Odorless paint for radiators. How to paint a cast iron battery: paint selection, surface preparation and painting technique Is it possible to paint a hot cast iron battery

If during the repair of the room it is not possible to replace the old radiator, you can improve its appearance by applying fresh paint. This can only be done with cast-iron heaters or old-style radiators. It is undesirable to paint a more modern aluminum radiator with fins with your own hands - you need to apply a thin and even layer of powder paint on them, it is quite difficult for a non-specialist to achieve a smooth coating at home.

In order to avoid mistakes, before starting work, it is worth studying the recommendations, watching photos and videos of the process.

Any paint will not work for painting an old battery.

The tool has the following requirements:

It must be heat resistant. Since the temperature of the radiator during the heating season reaches about 80 °C, the paint should not crack under such conditions.
Possess anti-corrosion properties.
Do not fade over time, be resistant to wear.
Contain in its composition a minimum of toxic substances or be non-toxic.

It is not recommended to cover cast iron radiators with oil paint - it exudes a strong odor, dries for a long time, has a toxic composition, and therefore is considered obsolete.

Suitable types of paints:

Work surface preparation

Before you paint a heating battery, you should prepare it for applying paint.

Even if it is planned to paint a new battery, it is necessary to properly process it: clean it from dust and dirt, sand it and degrease it. This is necessary so that the applied coating lies evenly and is fixed on the surface as firmly as possible.
If these recommendations are neglected, there may be problems later: the dried paint will begin to crack, its integrity will be broken, the surface will turn out to be uneven. In addition, the heat transfer of the radiator will decrease.

Together with heating appliances, cast-iron pipes are also usually painted, then they also need to be properly prepared.

Action plan:

dust and dirt are removed from the surfaces with a damp cloth;
get rid of the remnants of old paint;
the places of the radiator damaged by corrosion are thoroughly cleaned;
using sandpaper, the working surfaces are sanded and then degreased with alcohol;
a primer is applied to the cleaned surface (it is advisable to use an anti-corrosion primer to protect the batteries from rust).

All incomprehensible points can be clarified if you watch a video with the advice of professionals.

Work should be done with gloves, open the windows and protect the respiratory tract with a respirator.

Ways to remove old paint

There are two ways to get rid of the remnants of the previous coating.
The first - mechanical - use a spatula, sandpaper or grinder. Even with the help of an electrical appliance, the process will be very laborious, so the second method is more often used.

It consists in applying a chemical wash. The solution is abundantly applied to all painted surfaces, the battery is wrapped in a film to increase efficiency, left for the time indicated on the packaging of a particular product. Then, using a brush with metal bristles and a spatula, the easily detached old layer of coating is removed.

General rules

You can only cover a cold radiator with paint - applying it to a heated surface will cause the liquid to bubble, distribute unevenly, and the dried-up battery will be covered with streaks and streaks.

It is right to do this before or after the end of the heating season. If it is necessary to carry out painting in the winter, access to hot water to the radiator is blocked using valves, and work begins after it has completely cooled down. Re-open the valves only after the paint is completely dry.

Coloring process

Start applying paint from above, otherwise the lower painted parts will be damaged by streaks. The whole radiator is covered with paint, including its rear part. For a high-quality and durable coating, it is necessary to apply 2 thin layers, making a break between them so that the first one has time to dry.

To facilitate the process of painting the radiator with your own hands, you can remove it - so there will be fewer hard-to-reach places, and it will become more convenient to work. In this case, it is better to use a spray gun. You can study the photo, which shows the process of applying paint with this device, to appreciate the ease of working with it.
It is recommended to dilute the paint to a more liquid consistency if painting with an airbrush is planned. This is done taking into account its type: water-based emulsion is diluted with water, and white spirit is added to alkyd enamels and varnishes.

When working, the jet should be welded from top to bottom, holding the device at a distance of about 30 cm from the surface to be treated.

You can also get a smooth and evenly distributed layer of paint using a small diameter foam roller. For places in which they are inconvenient to work, it is worth using a brush with a curved end, designed specifically for this purpose.

The paint is applied sequentially, without skipping, without picking up too much liquid on the brush at a time. A thick layer will look uneven, worsen the heat dissipation of the battery.

After viewing step-by-step photos of the staining process, a video in which experts talk about the nuances of work, and taking into account the recommendations above, you can easily and efficiently update the old coating on batteries with your own hands.

How to paint a heating battery? - For those who have old cast-iron "harmonicas", this question worries literally every 2-3 years. Sometimes people think about this, who, during the current repair, suddenly discover that the color scheme of the radiator does not fit into the color concept of the room at all. Every year, on the shelves of construction stores, the range of paint and varnish products increases and it becomes more and more difficult to make the right choice. In this article you will find all the necessary information about what paint to paint the radiators on the old paint, how to do it, and whether this decision is always the right one.

It is undesirable to paint modern aluminum and bimetallic batteries. Initially, they are painted at the factory with resistant powder paint, which, thanks to the peculiarities of the technology, lays down perfectly evenly. If you decide that the original color of the radiator (usually white) does not match the interior of the room, and you want to repaint it, then you are unlikely to be able to achieve the same perfectly even coverage. Even if you dismantle the battery and cover it with paint in a horizontal position. In addition, an additional layer of paint will reduce heat transfer, which is a significant disadvantage for regions with severe winters.
It is undesirable to paint plate radiators, especially those with a large surface area. They are installed in houses where a network with increased internal pressure passes. They have low convection but high heat transfer. As for our question, due to its design, it is difficult to paint a heating radiator of this type with high quality, especially with a brush. If it is really necessary, then you will have to take it off, clean it thoroughly (which is very difficult) and paint it in a horizontal position with an airbrush or spray car paint. But even so, you may not achieve a perfect application. Missing areas may remain in hard-to-reach places, because the elements of the plate radiator are too close to each other.

Convectors, tubes with fins (especially with frequent aluminum fins) are not painted, because painting can adversely affect their heat transfer. The design of the convector, in addition to the heat source, includes a removable casing. It can be painted to enhance the overall look.
It is recommended to paint cast iron batteries. This is not difficult to do, the colors are different and they do not affect heat transfer. The choice of color is huge.
Painting of steel panel radiators is possible. But there is a nuance here - it will not work to evenly cover the surface of the battery with a brush. You will have to use automotive paint in a spray can, and it is advisable to paint in a horizontal position.

Important! In order to bring the battery as close as possible to the desired color and color scheme of the room, it is recommended to use decorative panels. They are sold in hardware stores and online stores. They can be made from wood, metal, plywood, plastic and even glass. These screens come in different shapes, colors and sizes. Figured carving, patterns, photo printing and more can be applied to them. So the choice is great, and you can pick them up for any, even the most sophisticated interior.

For painting a cast-iron radiator - straight and curved soft brushes, no more than 5 cm wide.
For painting a panel radiator - a foam roller of small width.
Paint in cans or spray.
Paint bath (if the paint is not aerosol).
Special paint remover (if you decide to get rid of old paint by chemical means) and a metal spatula.
Drill with a nozzle in the form of a metal brush for stripping the battery from paint residues.
Solvent.
Gloves, goggles, respirator or gauze bandage, protective clothing.
Newspapers, oilcloth, cardboard, masking tape to protect surfaces.
Rags.

What paints are suitable for painting a radiator?

In the process of repair, we think about how to paint the heating battery without smell, without streaks and streaks, so that the paint dries quickly and the beautiful appearance of the device is preserved for a long time. At the moment, there is no such ideal paint yet. However, there are several options for obtaining the optimal result.

For painting the radiator may be suitable:

water-dispersion and water-based paints;
alkyd enamel and auto enamel;
acrylic paint;
oil;
silicone-aluminum paint;
silver.

Let's consider each option in more detail.

Oil paint

Regarding this type of paint, we will immediately make a reservation that theoretically, of course, it is suitable. But in practice, it is almost never used for painting batteries:

Its biggest disadvantage is that it dries for a very long time. This process can take up to a month, you see, it is not very convenient.
In addition, oil paint has a rather unpleasant odor.
It is difficult to paint the surface evenly, without streaks and sagging.

Important! In view of such significant shortcomings, it is recommended to choose another option for these purposes.

Water-dispersion and water-based paints

Water-dispersion paint is made on the basis of polymers and water dispersion. Its main features:

It is moisture resistant and can be washed.
Diluted with water.
Mainly available in white.

The water emulsion is made on a water basis, and it:

It can have many colors and shades.
Not so resistant to abrasion, can be slowly washed off when in contact with water.
Diluted with solvents (eg white spirit).

Important advantages of this type of paints are:

their environmental friendliness and safety;
absence of chemical odors during application;
ease and simplicity of painting;
the possibility of tinting;
a wide range of application tools and affordable cost.

Important! The only negative is that the surface must be primed before painting, otherwise the water in the composition will cause rust.

Alkyd enamel and auto enamel

Alkyd enamel is one of the best options for painting a radiator. It behaves well at high temperatures (withstands up to 100 degrees), with temperature extremes, is resistant to abrasion and has many colors.

Regarding its capabilities:

This type of paint is sold everywhere and is relatively inexpensive. This is the familiar PF-115 and its imported counterparts (manufactured by ACE, Dulux, Sigma Coatings and others).
A significant disadvantage is the persistent chemical smell, which disappears for a long time after applying this paint to the battery.
In addition, poor-quality enamel may turn yellow over time.

Auto enamel also has a persistent unpleasant odor, so the room will then have to be ventilated for a long time. There are other nuances of application if you need to paint the heating battery:

Applying paint from a can is quick and easy, but this, of course, requires skill so that the paint layer lays down evenly.
With this application, unpainted areas may remain, and it is also necessary to carefully cover all surfaces surrounding the radiator from splashes.
Auto-enamel has a glossy sheen, it will give out and emphasize all surface irregularities.

Acrylic paint:

Acrylic paint is also water based.
It practically does not smell and has an affordable price.
The basic base is white, but if this color does not suit you, you can tint it in any other shade.
The temperature limit of acrylic paint is +80 degrees - this is quite enough for average radiators.
She dries quickly. It takes less than a day to apply 2 coats and it's all dry.
It does not turn yellow over time, but also requires preliminary priming in order to avoid the appearance of rust.
After drying, acrylic paint forms a polymer coating that is resistant to washing.

Silicon aluminum paint:

Perfectly lays down on any surfaces, forming a dense layer which narrows and expands together with metal.
It withstands temperatures up to 500 degrees, does not require pre-priming, is easy to clean by any means and does not lose its visual appeal for a very long time.

Important! This paint is one of the most expensive. Another disadvantage is the corrosive smell, which disappears for a long time.

Serebryanka

Known since Soviet times. On the shelves of hardware stores are its modern counterparts. For example, heat-resistant paint BT-177.

How is it different:

It consists of varnish mixed with aluminum powder.
Silverfish is inexpensive, but also has an unpleasant odor.

Color selection:

If you just want to update the look of the radiator without significant expenses, then paint it white. White and silver are classics of the genre.
If you want the batteries to be inconspicuous and fit into the decor, you can paint them to match the walls.
In a children's room, a radiator can be made part of a fun interior - cover it with bright paint or even make the sections multi-colored. You can apply patterns to the batteries with a brush by hand or using a stencil. It is possible to decorate the radiator with decoupage.

to content

What paint to paint the radiators - you already know, now let's get down to the process itself. It can be divided into two stages:

preparation (cleaning of old paint);
applying paint.

cleaning

Ideally, for high-quality cleaning, the radiator must be disconnected and the remaining water drained, since it will be difficult to get from the back side. We will miss how to wash the battery from dust and dirt, everyone will cope with this without additional advice. But there are several ways to clean up old paint.

Method number 1

The simplest and easiest method is to use a special wash. This chemical is sold in all hardware stores. But it is suitable for processing only cast-iron radiators, since cast iron is inert to this substance.

Procedure:

Method number 2

The second cleaning method is carried out using a building hair dryer or a gas burner.

Important! This method is not suitable for cast iron, as the process will take a long time and will be ineffective.

Procedure:

The essence of the method is to heat the paint layer to high temperatures with the device, and then scrape it off with a spatula or a stiff brush, without waiting for it to cool.
It is desirable to carry out such work in the open air, therefore, of course, the battery must first be removed. If this is not possible, protect the surrounding surfaces with plywood and open the windows.

Important! This method can damage the gaskets in the radiator, so be prepared for the fact that they will have to be replaced with new ones.

Method number 3

Another thermal method is processing the battery with a fire. The old “old-fashioned” method is laborious, but it allows you to clean the battery not only from the outside, but also from the inside.

Procedure:

Remove the radiator, unscrew all plugs and other parts.
Disassemble the battery into sections using a radiator key (the sections are connected by nipples with opposite threads).

Important! If this did not work out immediately, then you can do it after firing.

Build a good fire in the yard and put a radiator in it. Maintain the fire for about an hour, longer if possible.
After removing the battery from the fire, clean it with a metal brush, this process will be easy and fast.
After that, tap each section with a mallet to shake out all the rust accumulated over the years from the internal channels.
Now it remains to reassemble everything using new rubber gaskets.

Important! Gaskets can be cut out of an unnecessary car inner tube.

Wipe the radiator from dirt and degrease.

Method number 4

You can also use the mechanical method:

Put on a drill (grinder) nozzle - a metal brush or an emery wheel.
Treat the surface of the radiator.

Important! The disadvantage of this method is that it is difficult to reach many places with a tool, so the work will have to be finished manually, using a stiff brush and sandpaper.

As in the previous methods, the surface should then be cleaned of debris and degreased.

Painting

When asked whether heating radiators can be painted hot, experts answer in the negative, because most paints will not fit well on a hot battery. Painting is best done outside the heating season. If there is no way out already, then paint quickly, without picking up a lot of paint on the brush and then it, shading it with a thin layer. Or shut off the supply of boiling water to the radiator and wait for it to cool, then paint.

Important! During the dyeing process, remember to protect your eyes, hands, and respiratory organs from paint splashes and toxic odors.

After cleaning and degreasing, we proceed to the most important thing - painting. The procedure will depend on the type of dye chosen.

Acrylic and water emulsion

If your choice fell on acrylic or water-based paint, the radiator should be primed with an anti-corrosion compound, otherwise rust will appear over time.

Important! On sale there are paints in which the primer has already been added.

can paint

If you paint the battery with spray paint, then the technology is as follows:

Start in hard to reach places, and then move on to the front.
Move from top to bottom in zigzag movements, not stopping in one place, otherwise the layer will lie unevenly.
It is recommended to cover the surface with two layers, so after the first has dried, proceed to the second.

Important! You can take the radiator to the service station for painting, where specialists will do it professionally.

With the help of a spray gun

Painting with an airbrush takes place in the same way as in the case of spray paint.

Important! To reach all areas, it is better to paint the battery in the removed form.

Liquid solutions

If you paint with paints in liquid form, then protect the surrounding surfaces with oilcloth, as well as newspapers:

Pour the paint into the paint bath and with a curved brush, first coat all interior and hard-to-reach surfaces.
After that, with a straight brush, begin to process the front part, moving from top to bottom.

Important! Take a little paint on the brush, the layer should be thin, otherwise streaks will form.

After the first layer has dried, cover with the second. Two layers are usually sufficient.

Important! Acrylic paint and water-based paint dry quickly and without much odor, you can handle it without problems in a few hours. But alkyd enamel will dry out for more than a day and emit an unpleasant odor for a long time, so we recommend painting the radiator in the summer, when it is possible to open windows for a long time.

That's all the wisdom regarding the choice of paint for the heater and the process of applying the coloring matter. Using the useful information from the article, you can do everything correctly and with minimal losses. You can be sure that by successfully updating the old battery, the interior of the room will improve.

What should be the paint for batteries

A feature of any battery is that in operating mode it always heats up to a high temperature. Of course, the degree of heating depends on the temperature of the coolant and other additional factors. Regardless of whether, along with cast iron, steel or non-ferrous metal, the paint that is planned to be applied to the heating device will also heat up.

And so that the paint for heating radiators does not “please” with an unpleasant odor, harmful substances released into the air, as well as the loss of its solidity, it must:

withstand high temperatures;
do not contain toxic substances;
do not emit an unpleasant odor when heated;
be resistant to aggressive environments and abrasion.

Types of dyes for batteries

The above requirements are met by many types of paints, or rather individual representatives of these types. After all, most paints are designed for temperatures below +80 ° C. Therefore, manufacturers produce special modifications of their products.

In general, do-it-yourself painting of batteries can be done with the following types of paints:

acrylic enamels. They are based on organic solvents. This feature causes the release of the smell of the solvent during the application of the acrylic mixture to the battery. However, after drying, this smell becomes history, and a radiator with a pleasant glossy sheen appears in the room. This brilliance lasts for many years.
Alkyd enamels. They are known for their excellent resistance to wear and high temperatures. The range of colors of these enamels is very large, so many opt for such paints. These dye solutions also give off an unpleasant odor while drying. It can also be felt in cases where the heating radiator heats up very much.
Water-dispersion paint. Many experts note that such paint for radiators is optimal. This is because it does not upset the nose with a specific smell, and the drying time is very short. True, not every water-based mixture is suitable for batteries. Only the one on the packaging of which there is a corresponding designation is suitable. Its color can be any.
Oil paints. They were very popular in the past. Known for emitting a solvent odor at the time of drying and a long curing time.

It is worth adding that paint for a radiator may contain elements that resist corrosion and improve adhesion (they are constantly used in primers). Such mixtures have a different color, do not require primers and cleaning the radiator from corrosion.

At least that's what the manufacturers say. In practice, it is better to remove the rust of the heater and use a primer. The processes are long, however, the result is reliable. This is often noted in various videos.

Applying paint to a heating device

It seems that this process is quite simple, but it requires proper execution. Painting radiators includes the following steps:

Cleaning off old paint.
Removal of corrosion.
Degreaser treatment.
Applying a primer.
Do-it-yourself application of several layers of dye of a certain color.

The first four points are preparatory.

Features of preparation

There are two ways to remove a layer of old paint:

Mechanical.
Chemical.

The first involves the use of a spatula or a round metal brush attached to an electric drill. Working with a spatula requires physical effort, since they need to be moved by their own hands. Moreover, it will take a long time to wash the paint. This must be taken into account in calculating the total staining time. The disadvantage of this option is that it is difficult to reach the bottom of thin slots.

A round metal brush mounted on an electric drill is a more versatile method. It is able to process almost the entire area of the radiator, including many hard-to-reach places. At the same time, the time of work and the physical effort spent will be very small. Most people like this, including those who do the calculation of the repair time and shoot videos of the process.

The chemical method involves the use of special solvents or fatty acids. They process the entire area of \u200b\u200bthe battery and cover the treated surface with a film. Then they rest. The duration of the rest is indicated on the package. It may be different. During it, the paint becomes soft. Of course, it does not slip (and it would be very good), but its removal with a spatula, grinder or wire brush becomes very easy.

It is worth remembering that solvents emit substances harmful to the body. Therefore, when using the chemical method, you need to protect your hands with construction gloves, the airways with a gauze bandage, and even better with a respirator.

The surface of the radiator, cleaned of paint, is treated with sandpaper. They work especially carefully in places where there is corrosion. It needs to be completely removed. Only a pure metallic sheen should remain.

For degreasing use white spirit or any other alkaline solution.

The primer of the radiator is carried out with a solution that meets the following requirements:

is a product of the same manufacturer that produced the paint. In this case, the primer and paint are best suited to each other;
contains substances that can resist corrosion.

Features of applying paint

Before painting, the heating radiator must be cooled. This is because most paints are designed to be applied to a cold surface. If they are applied to hot metal, they will dry quickly. And this will not allow you to apply a uniform layer and correct smudges, stains and stains in time. In any case, under the condition of working on hot batteries, the time for applying paint becomes very short. In this case, the mistake made may remain uncorrected. This is often noted in different videos.

True, there are some exceptions. So, people who ask the question whether it is possible to paint hot batteries should pay attention to paints specially designed for this purpose. They are able to dry on heated metal very slowly. However, such paints are quite expensive, and the final result of calculating a small repair will be a considerable amount. Therefore, it is better, before painting the radiator in winter, to turn it off and wait for it to cool. It is best to change the color of the heating device in the summer season. Then it is convenient to ventilate the room and the batteries are cold.

If you have to paint a cast-iron heater during the heating season with ordinary paints, then you need to apply a very thin layer of paint. Apply two such layers.

The application of a coloring mixture of a certain color occurs in the following sequence:

Placing oilcloth or old pieces of newspaper under the radiator.
Applying paint to the top. Then they gradually go down. Thanks to this, such a problem as smudges is eliminated. First, the coloring mixture is applied to the internal parts of the device, and then to the external ones. You need to paint the entire surface.
Drying of the first coat of paint.
Apply the second layer in the same way as the first.

The battery is covered with paint using various tools, namely:

Brush.
Airbrush.
Spray can.

If you plan to use a brush, then you should take several of its options. The first should have soft, straight bristles. The other has curved bristles. Thanks to the second, you can work out with your own hands those places to which access is limited.

In the case of painting with an airbrush, it is better to remove the battery. So excess paint will not get on the walls. In addition, there is a great opportunity to paint the most inaccessible places. Spray painting is very fast. In this case, you need to perform zigzag movements. They move from top to bottom. The distance from the treated surface to the spray can should be 30 cm.

How to paint a heating battery: recommendations and photos

It is worth immediately clarifying that painting heating radiators is not possible in all cases. First of all, it is advisable to perform this operation for cast-iron radiators, on which a thick and uneven layer of paint not only spoils the exterior of the battery, but also greatly impairs the quality of heat transfer. The second type of batteries that can and should be painted are convectors made in the form of a bent riser pipe with fins pressed onto it.

Painting cast iron radiators

If you are the owner of modern models of radiators with aluminum sections, then it is better to refuse the idea of painting. Of course, you can paint it, but you will have to apply many layers of paint, and you are unlikely to achieve the expected effect. The fact is that the battery is painted with a brush, and this method is, by definition, worse than the factory one, so it is better to leave the new battery models alone, and if necessary, cover them with a decorative screen.

Brushes for painting radiators

Before proceeding to the main stage of work, you need to prepare. First, prepare soft brushes, which should be small in size and of two types - straight and curved. The straight brush is intended for painting external, easily accessible areas, and the curved one is for painting the rear and internal surfaces of the radiator.

What paint to choose

The main role in this work is played by paint for radiators, which can be of the following types:

water-dispersion;
alkyd;
acrylic;
oil.

Any paint for heating radiators must be resistant to abrasion, tolerate high temperatures (up to 100 degrees) and not emit toxic compounds when heated. In these parameters, the above options differ significantly from each other. For example, water-dispersion paints do not have an unpleasant odor and dry quickly, but this type of coating is less resistant to abrasion than others, that is, it will have to be updated more often.

Special alkyd enamel VD-AK-1179 for radiators

Acrylic paint has a chemical solvent in its composition, therefore, when used, an unpleasant odor is emitted, which takes a long time to weather out of the room. The advantages of such a coating are high abrasion resistance and an attractive glossy appearance.

Alkyd paint for radiators also has an unpleasant odor, but is in high consumer demand due to its high abrasion resistance and a huge range of shades. In addition, the smell from modern building materials is not so pungent.

As for oil paint, it is used less and less as a coating for radiators and pipes. The reason for this is an unpleasant odor, a long drying time and the difficulty in applying an even layer.

How to paint radiators is up to you, but it is best to use alkyd paints from well-known manufacturers. You just need to choose the right color for the cover.

How to paint radiators: preparatory stage

So, the materials are selected. Now you can proceed to the preparatory stage. Old cast iron radiators can have paint chips and many layers on top of them, so you need to completely clean the radiator from the old paintwork to the metal. This operation can be performed using a hot air gun, which melts the old paint with a jet of hot air, after which it can be removed with a spatula.

Cleaning pipes and batteries with a grinder with a special nozzle

If there was no mounting hair dryer at hand, then you can use an alternative option - a flushing solution. This solution is applied to the entire surface of the radiator, after which the heating device is covered with a film. After an hour of action of the cleaning solution, the paint can be removed with a spatula.

The main layer of paint has been removed, now we clean the battery from its remnants with fine emery or a special wire nozzle for a screwdriver. Then we degrease the surface of the radiator with a rag soaked in a special solution, such as white spirit. The final step is to cover the radiator with an anti-corrosion primer, which will protect the radiator from corrosion, but will also improve the adhesion of the paint to the surface.

Painting a heating battery: basic rules

It is immediately worth clarifying that the painting of the batteries should be done with the heating turned off. This limitation is due to the fact that the paint dries very quickly on a hot surface, which can lead to an uneven coating layer and smudges.

How to paint a heating battery after stripping

Before painting the radiator, lay an oilcloth or rag under it, which will protect the floors from paint getting on the floor. Start painting the radiator from hard-to-reach parts with a curved brush, and cover the front side with paint at the last moment. This approach will allow you not to smear the newly applied layer of paint, and your hands will remain clean.

Spray painting aluminum radiators

In order for the paint for the heating battery to lie evenly, it must be applied in two thin layers. To apply the second layer, you need to wait for the first to dry completely.

Possible painting problems

During the implementation of each stage of work, unforeseen difficulties may arise - the paint falls unevenly or the old coating is not removed. In order not to spoil the materials, you can pause work, wait until it dries completely and start again by cleaning and degreasing the surface.

You can find out what paint to paint radiators with consultants in a specialized store, they will help you decide on a specific brand that is most popular among buyers.

To avoid additional difficulties, pay attention to the video instruction, where experts will help to study the painting algorithm in detail and follow the detailed steps.

Outcome

Painting radiators plays an important role, as this element of heating attracts attention and is a subject of interior and design of the room. Using the above tips, you can ensure that the old cast-iron battery after processing will look no worse than the new one, and the coating will last for many years.

Choosing an odorless paint for radiators

The choice of paintwork for the heating system is a rather relevant and undoubtedly important issue. The paint must meet the objectives: withstand high temperatures, maintain gloss for a long time and not snap off. But this is its functional and aesthetic load. But the question of what kind of odorless paint for radiators and how to paint them sometimes remains open. An informative excursion into the world of paints and varnishes will help to understand.

Which one is better to choose

The choice of paint for the heating system of an apartment or house is closely related to the material from which the batteries are made. Each of its types has certain properties that are friendly to the paintwork or conflict with it. The main types of materials used for the production of radiators:

cast iron;
bimetal;
steel;
aluminum.

For painting heating radiators, the market of manufacturers offers a wide range of species and a rich palette of coatings:

№	Varieties of coatings	Kinds painted radiators	Advantages	Flaws	Firm- manufacturer

Can it be hot dyed?

The opinions of experts on the issue of painting radiators differ: some argue that they need to be painted to protect them from corrosion. Others retort that the application of one or another type of enamel on radiators does not perform any protective function and is purely aesthetic in nature. Another thing is painting pipes in winter when the radiators are hot.

Paints and varnishes suitable for the heating system and withstanding high temperatures require painting on cold batteries. If the radiators are covered with enamel on a hot surface, then the paint will dry “on the fly” and the quality of the coloring will get out of control: sagging and unsightly spots will appear.

It would not be superfluous to recall that when covering a hot radiator, the smell of paint will increase, and opening windows in winter for ventilation is problematic due to the cold.

Important! Consumers most often choose the white color of the battery coating, but experts say that the dark tone of the radiator color contributes to better heat dissipation.

The painting process

Before proceeding to the stage of applying paint, you need to stock up on the necessary equipment:

radiator brush (curved, with a long handle);
regular brush (100 mm wide);
rubber or silicone gloves;
respirator (if paintwork is odorous);
newspaper (to protect the floor from paint stains);
sanding sheet No. 2 (if necessary, cleaning the batteries from irregularities);
rag;
primer;
dye;
white spirit (for unexpected skin contact with paint).

Sometimes, the preparatory work takes more time than the staining process itself. This is not surprising, because the radiator has a lot of hard-to-reach parts that need to be washed, and in some places peeled off paint and sanded.

Important! If there is a desire to remove the old coating completely, then you can use a special wash.

Prime the prepared surface.
In order to avoid drips, painting starts from the top of the heating system.
The internal parts of the batteries are also coated first.
Layers of paint are applied evenly in a thin layer.
As the paintwork material dries, the radiators are repainted.

Stages of painting a radiator

Technology of painting on old paint

The condition of the paint on the heating system can be different:

The coating, although old, faded, but has a monolithic adhesion to the base. It is enough to sand the surface a little with sandpaper for reliable adhesion of the next layer of paint.
The old coating is worn in places, peeled off and metal is visible in places. Here, a more thorough grinding of the surface will be required so that chips and irregularities do not show under the new layer.
The paintwork is hardened, flaky in large areas, rust shows through in places. Such paint must be mercilessly removed with a metal brush or special preparations for washing. The prepared surface is primed before applying the first layer of paintwork materials.

Important! You can simply update the old paint: apply a fancy pattern to it, after sanding, for better adhesion.

in cans

For the convenience of consumers, paint and varnish manufacturers produce an aerosol coating for radiators. It has excellent properties:

withstands high temperatures;
easy and quick to apply;
dries almost instantly;
has a pronounced gloss;
adheres well to any surface.

The only negative is a strong smell, but it will disappear in just an hour.

Balloon paint is sprayed onto the surface to be painted from a distance of 30 cm. The movements should be smooth, but fast, in a zigzag pattern. Depending on the quality of the surface of the heating battery, it may be necessary to paint in several layers.

Important! When working with aerosol enamel, it is necessary to cover a large area around the radiator with newspapers, because. skill in painting with spray paint will not come immediately.

Having the necessary information about the coatings of radiators, you can get useful tips and learn about the features of the technologies for using paint and varnish products.

Welcome!

Agree, the peeling paint on the batteries looks extremely unattractive. In addition, in the places of cleavage, the metal oxidizes over time and becomes covered with rust, which shortens the life of iron heaters. The paint for heating radiators presented on the market of building materials allows solving this problem. However, a wide range of radiators and enamels can confuse not only a simple man in the street.

We offer you to figure out what paints and varnishes (LKM) can be used to paint batteries, as well as how to properly paint them.

When painting, special attention is paid to the internal elements of certain types of radiators. For example, the steel plates of convectors, the so-called comb or "ribs" strung on pipes, cannot be painted. An additional layer of paint will significantly reduce the level of heat transfer. Only front flaps and screens are painted.

What parameters should the paint meet?

For painting radiators and heating pipes, special paints and varnishes must be used that meet the operating conditions of the heating circuit. The following requirements apply to them:

Temperature resistance from 80⁰С and above. With insufficient resistance to heat, the paintwork will turn yellow or change its original shade already in the first heating season, crack and begin to peel off.
High thermal conductivity. A low thermal conductivity index will lead to a decrease in the heat transfer of the heater.
Anti-corrosion and moisture resistance. The main purpose of painting radiators is protection from the harmful effects of the environment and rust. To do this, the paintwork must not be porous.
Resistance to abrasion and mechanical stress.
Environmental friendliness and safety. The paint should not contain toxic substances that evaporate especially actively when the house or apartment is heated and thereby harm human health.
It is desirable that the paint for batteries be quick-drying and without a strong odor.

Types and differences

There are a lot of heat-resistant enamels on the market. To understand which one is best suited for your radiator, you need to focus not on the manufacturer, but on the basis of the paintwork. Not the least important is the planned method of application and the decorative effect that you plan to get after staining.

We note right away that we immediately exclude traditional oil paints from the review. Although some of them are marketed as heat-resistant, in general they are not suitable for hot pipes.

Alkyd

The composition of alkyd heat-resistant paints includes alkyd varnish (glyphthalic or pentaphthalic), a solvent (most often, white spirit), microfillers based on granite, sand or marble, and coloring pigments. Some formulations can be supplemented with antiseptics that protect the surface to be painted from damage by fungus and mold.

High hiding power allows the use of alkyd enamels both for the main coloring and for creating a decorative pattern over the base coat.
Elasticity ensures evenness and smoothness of the coating, and also prevents the effect of shrinkage.
Resistance to abrasion, moisture, corrosion and temperature changes guarantees the durability of the coating.
Color stability.
High adhesion index with metal.
Drying time - from 12 to 36 hours.

Of the shortcomings:

Insufficient heat resistance. Designed for heating circuits with a heating temperature of not more than 80-100⁰С.

Organosilicon alkyd enamels with increased heat resistance (up to 600⁰С) are distinguished into a separate category. Silicones are significantly more expensive than conventional alkyd compounds, but they are used to paint fireplaces, chimneys and stoves.

A specific pungent odor requires mandatory ventilation of the premises in which the staining is carried out. The first heating of the pipeline will also be accompanied by the appearance of a pungent odor.

Important! Pay attention to the digital encoding indicated on the label. "2" indicates the possibility of using the paint in the premises, and "8" ranks it among the heat-resistant.

Acrylic

Acrylic paints for radiators are a mixture of acrylate (acrylic polymer emulsion) with a color pigment and water. The polymer coating lays down in an even, smooth layer, not prone to smudges.

The temperature maximum is 120⁰С.
Without smell.
Ultra-fast drying - from several minutes to several hours.

A special advantage of acrylic enamel over analogues is that it can be applied even to a hot battery. This fact does not affect the quality of the coating and the period of service of the coating. Among the shortcomings - instability to mechanical abrasive wear.

Hammer

Hammer paint is a type of alkyd enamel based on a nitro-polymer with a dye. A distinctive feature is the decorativeness of the coating, which imitates a metal surface beaten off with a hammer, while hiding small irregularities. Hence the name.

Additional advantages of using hammer paints will be:

Refusal of preliminary priming. A prerequisite is only mechanical cleaning of the metal from dust, while the active elements of the coloring composition can easily cope with grease stains and rust, simply by dissolving them in themselves.
The highest adhesion with a metal surface. And during the preliminary sanding, the paint is so eaten into the structure of the metal that it can subsequently be reduced only by chemical means.

Water emulsion

Water-based (water-dispersed) paints are made from water, pigments and polymers. Depending on the type of binding base, they are divided into:

Polyvinyl acetate (PVA);
Polyacrylate.

PVA paints are characterized by low resistance to moisture, so they are definitely not suitable for batteries.

Polyacrylate is a subspecies, which we talked about above.

silicate

Silicate compounds are coatings based on liquid potash glass, ethyl silicate and powdered metal pigments. The presence of zinc and aluminum pigments gives the coloring composition anti-corrosion qualities.

According to the type of binder, silicate paints are:

Silicone.
Dispersion-silicate. One-component formulations based on pure acrylate, ready to use.
Silicate silicone. Two-component: separately - powder, separately - liquid glass, which are mixed before painting.

It is the presence of organosilicon resins in the composition that gives radiator enamels unsurpassed strength.

Of the undoubted advantages - fire resistance, of the minuses - high toxicity during staining.

Powder

Powder dyes are a polymerized pigment powder sprayed onto the surface to be painted in a special high-temperature box at a temperature of 170-350⁰С, where it melts and forms a reliable, durable coating.

Unfortunately, this staining technology is used only in factories and specialized auto repair shops, and is not available for self-performing at home.

Aerosol

One of the alternative painting methods is spray paint. Modern technologies allow almost any type of paint to be produced in aerosol cans. Among the presented range of aerosols, it is important to choose exactly heat-resistant compositions, in extreme cases - car enamels, which were originally designed for adhesion to metal and high temperatures.

Serebryanka

If you want to give the batteries a characteristic silver tint, you can use a do-it-yourself silverware made from PAP-1 pigment aluminum powder and BT-577 bituminous varnish.

The heat resistance coefficient of this coating with the correct component ratio reaches 300-400⁰С.
Serebryanka is not subject to delamination, is resistant to corrosion and external influences. The coating will last at least 10 years.
Dries quickly and is non-toxic.

On a note! Serebryanka is not compatible with most other paints, therefore, it requires a complete cleaning of the surface to be painted from the remnants of the previous paintwork.

Matte

Matte finishes look respectable, especially on cast iron batteries with a textured pattern. But it is better not to choose matte white paints. The microporous structure is prone to the accumulation of dust, which means that white will soon acquire a gray tint.

Glossy

Gloss is ideal for batteries with a perfectly smooth surface, as well as for cast iron radiators, if the goal is to smooth out their characteristic roughness. In addition, the smooth texture is easy to care for, just wipe it with a soft, damp cloth.

The composition of the enamel is supplemented with fine chalk or titanium dioxide. Chalk, unlike titanium dioxide, provokes a change in the color of the paint. Give preference to titanium components.
When choosing the right paint, pay attention to the markings. The inscription "For heating radiators" and an emphasis on compliance with GOSTs will ensure that the technical parameters comply with the requirements indicated above. You should not choose products manufactured according to dubious specifications.
Be guided precisely by the mass of paint, and not by displacement. The larger the mass, the higher the hiding power index. Diluted enamel adds volume, but loses coverage.

What paint to choose for aluminum or cast iron radiators

It should be noted that each type of metal has its own paint and coloring technology:

Cast iron is characterized by excellent adhesion to almost any kind of enamel. In this case, you should be guided by the effect that you want to achieve after staining. A paint with a dense viscous structure will hide the rough texture, while a light one, on the contrary, will emphasize the showiness of cast iron.
Aluminum and stainless steel are more capricious in choosing the right paintwork. The painting technique used at the factory (powder coating and heat treatment) is practically not feasible at home. Therefore, priority is given to high-quality paint materials with a high adhesion coefficient - alkyd or acrylic. Some experts talk about the effectiveness of aerosol paints applied to hot batteries.

Epoxy primers designed to treat metal before painting will help enhance the adhesive effect.

How to calculate paint consumption

On the labels, the manufacturer always indicates the average consumption of paintwork per 1 m². Thus, it is not difficult to determine the required amount of enamel when it comes to flat radiator models. But here, too, one should not forget about painting the inside of the battery. With cast-iron accordion radiators, it is still more difficult.

In this case, technical documentation for heaters will come to the rescue, usually it indicates the total area of \u200b\u200bthe product. If the registration certificate is not preserved, special online calculators are used.

Calculator

The online calculator takes into account all the parameters of the upcoming work:

battery model.
Number of sections.
Paint type.
The need to paint the pipeline.
Estimated number of layers.

The program automatically gives the result in kilograms, taking into account a 10% reserve or the total surface area for painting, according to which you yourself need the desired volume of the product.

How to remove old paint

The basic rule for painting used radiators is to remove the old paintwork. You can accomplish this task in one of two ways (or in combination):

Mechanically.
With the help of chemicals.

For high-quality cleaning and subsequent painting, it is better to remove the battery from the wall.

mechanical way

Mechanical cleaning involves the removal of the old paintwork with handy tools.

First, the battery, and if necessary, the pipe, is cleaned of dust and other contaminants with a damp cloth. For best results, you can use a vacuum cleaner.
Then the surface is carefully sanded with sandpaper. . To speed up the process, a drill with a brush attachment with stiff bristles or a grinder is used. To remove paint in hard-to-reach places, you can use a building hair dryer, it heats up the enamel, which is then removed with a scraper.
Finally, the work surface is again dedusted and degreased.

There are many disadvantages of mechanical cleaning:

High labor and time costs.
The process is quite dusty.
There is a high chance of metal damage.

On a note! If the paintwork on the radiator does not show signs of wear (bloating, peeling, rusting), but still needs to be replaced, it can not be removed. To ensure adhesion to fresh enamel, it is enough to lightly sand the radiator coating.

By chemical means

For chemical cleaning, special preparations, washes are used. They soften the coating that has served its age and stimulate its peeling from the metal.

Apply them in a dense, even layer with a brush with natural bristles. The gel form of the drug adheres well to the surface.
After the time specified by the manufacturer, the wash is simply removed with a wooden spatula along with the dissolved paint, and the radiator is washed with soapy water.
The cleaned battery is additionally treated with a corrosion inhibitor, after which it is degreased.

On a note! Some manufacturers produce washes with a corrosion inhibitor already included in the composition. They cost a little more, but significantly reduce the time to prepare the radiator for painting.

It is important to remember that chemicals are toxic and flammable. Therefore, work must be carried out in a well-ventilated area away from sources of fire. Personal protective equipment will also be useful - a respirator, gloves and goggles.

How to paint heating radiators with your own hands

Battery preparation

Removing the old layer of paint is only the first preparatory stage. In the future, the following recommendations should be followed:

Irregularities and roughness are leveled by putty on metal. After its setting, the surface of the battery is cleaned again, dedusted and degreased.

On a note! If you plan to paint with acrylic enamels, it is better to use acetone as a degreaser, and white spirit or gasoline for alkyd compounds.

The next step will be priming. This also takes into account the type of future coverage. The basis of the paintwork and primer should be of the same type.
Each coating (putty and primer) dries naturally at room temperature.

Painting process

Staining is also carried out at room temperature. In this case, it is desirable to choose the period between the heating seasons (before or after). Only some types of paints can be applied to a heated battery.

Being engaged in the repair of residential or industrial premises, almost every person wants to choose high-quality consumables that will be safe for health and have good characteristics. A particularly important issue in this matter is the choice of paint for radiators. The difficulty lies in the fact that in the case when it is chosen incorrectly, it will take a lot of time to completely dry the treated surfaces. After heating the radiators, the room will be constantly filled with a pungent and unpleasant odor, and the layer will easily snap off.

Due to the fact that heating batteries often change their temperature and often heat up to too high rates, the coloring matter used must necessarily be calculated taking into account these features. Therefore, preference should be given only to well-tested brands that produce high-quality heat-resistant products that do not emit unpleasant odors, do not turn yellow when heated frequently, and also meet all generally accepted requirements for these products.

Today, many manufacturing companies offer a fairly wide range of products such as odorless paint for radiators. Thanks to this, buyers have the opportunity to choose the most suitable type for themselves:

acrylic enamel;
Alkyd enamel;
Oil enamel;
Water based.

All types differ from each other in production technology, composition and characteristics.

acrylic enamel

Acrylic paints:

do not have a characteristic odor and are great for interior work.
Their widespread use in everyday life is also due to the fact that they are quite dry quickly,
different increased moisture resistance,
uniform application on any surface
and are also absolutely safe for people.
Due to the fact that the composition of the substance includes special additives, a layer of paint does not start to crack and turn yellow when the temperature of the radiator or battery rises.
In addition, it should be noted that manufacturers offer huge range of colors, therefore, acrylic paint for heating radiators is often used in the decoration of surfaces.

As for the shortcomings, the most significant of them is high price. However, it is fully consistent with the good performance of the paint.

Alkyd enamel

Alkyd paints, manufactured using the latest technologies, have the following advantages:

The surface covered with a layer of such a substance is resistant to elevated temperatures - it does not crack when heated up to 120 0 С;
High strength;
Homogeneous structure layer during application;
Good abrasion resistance during the operation of heating batteries and radiators;
Wide range of colors allows you to choose almost any color;
Layer maintains integrity for a long time.

However, in addition to the advantages, there is also a disadvantage - for several days after painting, the bad smell, which can later appear with sufficiently strong heating. In addition, some brands sometimes fade a little, and may also change the shade.

Water based enamel

Water-dispersion paint for hot radiators, odorless, is an excellent option for coating radiators. It differs from other species in a number of features:

It is made on the basis of ordinary water, so it is absolutely safe for people and environment;
Special dispersed particles are not harmful;
No unpleasant odor;
For complete drying absolutely required a little time;
Easy to apply and even layer
Due to the water-repellent effect, the dyed batteries can be washed without destroying the layer;
Suitable for use in most different rooms.

The disadvantage can be not too many colors because it's mostly white.

oil enamel

Oil products are in rather high demand due to a number of their advantages:

No harsh or unpleasant odor after application and further heating of batteries and radiators;
Are divided into colored and colorless;
Easy to apply on metal surfaces;
form uniform layer;
Fine suitable for indoor use both residential and non-residential premises;
Low cost compared to other types of battery paints;
Can be used for decoration surfaces - applying patterns and complex patterns.

The downside is that complete drying requires a lot of time. This is due to the fact that a solvent is added to the paint.

How to choose the right paint for radiators?

A wide range of different brands leads to the fact that buyers are faced with the problem of which paint to prefer. Therefore, when choosing, it is imperative to pay attention to whether the enamel meets the following requirements:

Go to bed exactly for metal products;
Provide protection from rust and corrosion damage;
Withstand increased temperature;
keep original color for a long time.

When choosing a paint, it is important to consider the material from which the radiator is made.

In addition, it is also necessary to take into account what material the batteries and radiators are made of. After all, they can be made from a variety of metals, as well as their alloys. Experts recommend following a few tips:

For devices made of steel, aluminum and bimetal composition is better to use acrylic or alkyd paints;
For cast iron batteries are well suited to any kind of enamel, except for oil. However, in order for the substance to lay down in an even and thin layer, it must be mixed with a diluent;
It is better stop using oil paints even the most famous brands, because it very rarely performs protective and decorative functions at the same level as others

How to properly paint?

There are two ways to apply the product: on an existing coating or from scratch. In both cases, the whole process is carried out in two stages:

Preparatory work;
Application of the substance.

Training

In the first case, it is necessary to knock off the crust of their old enamel over the entire surface and in hard-to-reach places by performing the so-called sanding. After removing the old paint from the radiators, they should be treated with a rust converter. If there is no coating on the surface, then it must first be cleaned of grease, dirt and dust residues so that they do not distort the color of the freshly applied layer, and then coated with an anti-corrosion compound.

To obtain the highest quality result, the preparatory work should be done in the following order:

Deleted old layer;
Places with rust carefully are cleared until a metallic sheen appears;
Whole surface sanding using sandpaper;
Product needed degrease with white spirit or slightly alkaline solution;
Applied primer to protect metal from corrosion.

Painting

Before proceeding directly to the coloring of the batteries, you need to provide the appropriate conditions.

Yes, the device must be disabled,
and its surface temperature should be the same as in the room, but not lower than 15 0 C. Otherwise, the base will not dry and will not be able to polymerize.
To make the result look neat, a radiator or battery must be removed.
To reliably protect the surface from corrosion, it is necessary to completely cover the internal surfaces, the back panel, the lower parts lamellas.

It is important to paint the radiator with the heating turned off, otherwise the base will not dry.

Coloring begins from the inner ribs, rubbing the substance well with a brush. At the same time, you need to make sure that there are no leaks.
After everything is dry, they covered again paint and at the same time capturing and bezels. It is better to apply paint in several layers so that there are no gaps.
After that the device should not be connected within 5-12 hours so that the enamel has time to fully polymerize. If the work is done correctly, the result pleases for about five years.

Popular brands of odorless battery paints

Almost all companies producing such products offer paints that are suitable for painting radiators and batteries, performing a protective and decorative function.

Among alkyd enamels, the following brands are especially popular:

"Miranol";
"Malta 30";
"Jamaica 90";
"Dufa Heizkorperlack";
"Tex".

From the range of acrylic enamel often get:

"VGT Profi";
"Jobi Termoaquaemail";
"Barbados";
"Colorika Aqua";
Ceresit CF 33
"Tikkurila";
"Euro Extra 20";
Caparol Samtex 7 ELF.

Water-based paints are also in great demand:

"Tikkurila Thermal";
Dulux Master Lux Aqua.

Of the oil types, the following brands are often preferred:

Alpina Heizkorper.

These brands differ from each other in color, some properties and price. Each buyer can choose for himself the product that will fully meet his requirements.

Prices and reviews

The cost of paint, which is odorless and suitable for heating batteries and radiators, is affected by its type and brand, as well as its main characteristics.

The price of a can by weight 2.5 kg is:

Enamel for heating batteries brand VDAK 1179 from company VGT is 600-670 rubles;
Brand "Rogneda" produced by the company Dali costs about 570-650 rubles;
"Dufa Heizkorperlack" – 1500-1700 rubles;
"Tex" costs 1100-1270 rubles;
Enamel for heating radiators "Tikkurila Thermal" will cost approximately 2900-3300 rubles;
Brand "Alpina Heizkorper" worth about 1300-1450 rubles.

If properly painted, the battery can keep its beautiful appearance for up to 5 years.

Despite the fact that all of the above brands are widely used in the construction industry, some of them are much more popular than others. This difference is due to the fact that they are of different types and differ from each other in characteristics and properties. Therefore, they receive different reviews.

Most users prefer acrylic or alkyd enamel, noting:

their resistance to abrasion and cracking,
as well as ease of maintenance of painted surfaces.
In addition, they are attracted by a large range of colors.

O oil and water-dispersed paint

During the operation of the heating system, it may be necessary to paint the batteries. The quality of the work performed determines the appearance and durability of the heater. Therefore, it is important for users to know how to paint a heating radiator with their own hands.

Paint selection

Taking into account the specific operating conditions of radiators, the following special requirements are imposed on the paintwork:

high temperature resistance. The coating must be designed for continuous operation at a temperature of 80-90 degrees;
color stability. The coating must retain its original color for a long period;
high protective qualities. It is necessary to choose paints that provide effective protection against corrosion;
good adhesion. The paint should fit well on the metal surface and not peel off during the operation of the radiator;
high strength and wear resistance of the created coating;
safety. When heated, the coating should not release toxic substances and foreign odors into the air.

Best of all, modern acrylic paints meet all these requirements.

Coloring technology

Before you paint the heating battery, it must be cleaned of the old coating. This can be done manually with a metal brush. You can also use a grinder with special attachments. Another option is to use special chemicals. For example, it is convenient to use aerosols, under the influence of which the old paint peels off easily. After removing the paint, it is also necessary to get rid of rust, dirt, and thoroughly degrease the surface.

The cleaned surface must be carefully primed. For this, a primer recommended for use in conjunction with the selected paint is selected.

After that, you can proceed directly to staining. At least two brushes are used. One, ordinary, brush is used for painting external surfaces. The second brush should have a long, curved handle. It easily penetrates into hard-to-reach places, so it is convenient for her to paint inside the radiator fins. Before use, you need to fluff the bristles of the brushes, which will get rid of loose hairs. First, the inner surfaces are painted, and then the outer ones. In this case, staining is done from top to bottom, which helps prevent the formation of streaks and drops. The radiator needs to be painted in two layers. In this case, the second layer is applied only after the first has completely dried.

Painting of bimetallic and aluminum radiators

Available already with paint finish. It is applied by powder coating in the factory. Such a coating is characterized by high protective properties, mechanical strength, wear resistance, and temperature resistance. Due to this, these radiators do not require painting during operation.

The exception is cases of mechanical damage to the radiator coating during transportation, installation, operation. To remove chips and scratches, you can use automotive putty. It is also best to paint damaged areas with car enamel, the quality of which is comparable to the quality of the “native” coating. For application, it is convenient to use aerosol cans. It should be borne in mind that car enamel dries better and faster on hot radiators.

If you need to completely repaint an aluminum or bimetallic battery, then this does not require the removal of the old coating. The surface must be degreased and coated with a primer. After that, with a spray gun, you need to apply paint of the corresponding color in two layers. Water-based or alkyd paint is best suited.
