Oil paint has recently begun to be presented as something harmful, dangerous and inapplicable for use in residential premises. Indeed, this paint is made using volatile solvents. However, if you ask about the volume of production of oil paint for walls, it becomes clear that the demand for it has not fallen at all. Of course, painting the walls in the bedroom with oil paint is not worth it, but there are many other surfaces on which such a coating is quite acceptable and even irreplaceable.

What does oil paint for walls consist of?

In general, there are many options for the composition of oil paint, but we will consider the most common composition for construction.

Features of the manufacture and use of oil paints
The use of protective coatings by people for wooden or iron structures and products has been going on for more than one millennium.

Currently, repair work of any complexity is carried out easily thanks to the professionalism of the builders, innovative technologies and a wide variety of finishing materials. Paints and varnishes also play an important role in achieving repair efficiency. Their assortment is made up of various types of paints.

Peculiarities

Oil paints are paints and varnishes that are made in the form of suspensions with vegetable fillers. Depending on the type, they are used in painting, for painting wooden and metal surfaces.

The main components of paints are pigments and binders. The former give the paint a specific shade. They usually change the characteristics of the resulting suspensions, for example, they can slow down or accelerate hardening, reduce corrosive wear, and increase the service life.

There are several types of pigments:

colored (chromatic);
black and white (achromatic);
organic;
inorganic.

Oil paints are made with pigments on both organic and inorganic bases. Pigments are made from mineral flour that does not dissolve. Linseed oil is used as a binder. Coloring compounds settle at the bottom of the can, so shake the can thoroughly before starting work.

The second main component of paint is considered to be a filler, which is used in order to save pigment. These include kaolin, talc, mica. To improve performance, for example, for faster drying, a desiccant is added to the paint. It is a cobalt, manganese, lead salt that can dissolve in drying oil. In order to facilitate the dispersion of the pigment, surfactants are used.

Drying oil is the main component of natural paints. In recent years, their cheap synthetic substitutes have been increasingly used. Due to the slow evaporation of oils, drying of the painted surface will take quite a long time. Only with the addition of desiccants is an accelerated drying process possible.

The following types of drying oil are used for the production of oil paints:

In the composition of natural drying oil, the content of vegetable oil reaches 97%. Linseed, sunflower, soy, hemp base is used as oil, the remaining 3% is a process catalyst.
Oksol contains a little more than half of the composition of natural oils, 40% - white spirit as a solvent, a drier accounts for 5% of the composition. Unlike natural drying oil, the price of oxol is much lower, but due to the solvent content it prevents ozonation.
In the combined drying oils, the composition is the same as in oxol, only in different percentages. The solvent accounts for up to 30% of the total mixture, 70% is vegetable oil.
Alkyd drying oils are alkyd resins mixed with natural oil, a catalyst and a solvent.
The composition of synthetic drying oils includes products of oil refining and other industrial waste.

Sometimes, if necessary, the composition is brought to the required density. The following diluents are used for oil paints:

turpentine is an essential oil with a complex chemical composition, which is obtained by processing the resin of conifers and resin.
white spirit is a residual product of oil refining.

Since all diluents are active chemicals, they must be used with care. They are added gradually, in small portions, since the high content of the diluent destroys the bond between the pigment and the drying oil.

Specifications

For the correct choice of paint and varnish material, you need to know the most important characteristics of oil paint:

Content of film-forming substances. The best option is more than 26% of the total volume. For the durability of the paint, it is necessary to know the percentage of these components. The higher it is, the longer the service life of the coating will be.
The content of volatile components in the composition of the paint and varnish material usually lies in the range of 10%, since they are toxic and harm human health. At ambient temperatures over 20 ° C, they evaporate and give off a specific odor. Therefore, after painting the surface, it is recommended to ventilate the room.
The degree of grinding of the paint components. This indicator should be below 90 to obtain a smooth surface, and at high values, the probability of surface roughness is high.

The viscosity of a quality paint is in the range of 65 - 140 points. The fluidity, as well as the curing time of the coating, depends on it. A good oil paint dries in about 48 hours.
The hardness of the film is especially taken into account when treating external walls. With an increase in the degree of hardness, the service life of the paint increases and the effect of external factors on it decreases.
Absolute hydrophobicity is important for separating external walls, and for internal walls, the indicator ranges from 0.5 to 1 unit.

Advantages and disadvantages

Advantages of oil paints:

the possibility of using for internal and external walls;
fit well on an untreated wall, as well as over other paints;
resistant to frequent washing;
low consumption due to high coverage;
low cost compared to other types of paint;
good adhesion ability;
reliable surface protection.

Disadvantages:

due to the content of toxic components in the composition, a person may experience a severe allergic reaction;
sharp unpleasant odor;
dry for a long time (sometimes up to several days);
the painted surface gradually peels off and cracks due to the lack of the ability of the paint and varnish material to breathe;
when the paint is stored for a long time, it undergoes some changes: it acquires a rubbery or gelatinous appearance, the mass hardens. Such paint becomes unusable.

Despite significant drawbacks, oil paints are produced in large quantities. GOSTs strictly control the quality of these finishing materials, designating each type of paint with various combinations of letters and numbers.

Types and scope of application

Currently, two types of oil paints are produced: pasty, or thickly grated and liquid, and ready-to-use. The first is obtained in a mixer and grinding on a special grater. Obtaining the second type involves mixing the composition in ball mills or diluting pasty paints with natural drying oil.

The area of application of alkyd materials depends on the pigment and varnish used. They are applied to surfaces made of wood, metal, concrete, plastic, bituminous plaster. Often used for finishing as a primer. They are used to paint pipelines and batteries.

The paint is often used to protect against high humidity due to their water impermeability, which enamel and tempera coatings do not have. But this advantage of oil paints interrupts a serious drawback: during operation, the paint peels off on the surface and disappears.

When staining, it is necessary to take into account:

When processing window frames, door trims, walls and glass are usually dirty. Removing oil-based stains will not be easy, so you need to protect parts that should not get dirty beforehand. The walls can be made with plywood, cardboard, tin sheets, and the glass can be pasted over with paper.

If you still manage to stain the glass, you can prepare a mixture of crushed chalk and an aqueous solution of washing soda. The mixture should be in the form of a paste. It is necessary to apply the consistency to the glass and leave it as it is. The paint will soften and can be removed with cloth or paper material. To remove dried paint from the wall, apply aluminum foil and iron it with an iron. Then the soft paint can be removed with a spatula.
A drill can be used to stir the paint to avoid contaminating clothing. To do this, you need to make a hole on the lid of the can, stick in the rod and fix it with the back side in the drill. It remains only to turn on the device and mix the contents of the jar for 60 seconds.

To remove paint from the body, you need to use a special dissolving agent, but if it is not at hand, then you can try to cleanse the skin with vegetable or animal fat. Also, powder for washing clothes will do a good job with this task.
After painting windows and doors, you cannot close them until the paint has completely dried, but if the need arises, you need to lay foil between the sashes.
It is better to paint walls made of metal with a spray gun - this way the surface will look neater.

Colors

The coloring of a paint in a certain color depends on inorganic pigments - achromatic, giving black and white, and chromatic, giving color shades.

Achromatic pigments allow you to get:

zinc white, which is widespread and cheap, imparts a white color;
titanium oxide also imparts a white tint;
lipoton - zinc sulfide mixed with barium sulfate gives a shade of white;
carbon black (soot) and graphite impart dark pigments;
zinc, aluminum, brass, bronze powders give a bronze, silver (metallic), matte shade.

The most common chromatic pigments are:

yellow - iron hydroxide;
iron oxide - red;
red litharge - lead oxide;
brown - chromium oxide;
green - cobalt.

All information about the paint is written on the label, where the main purpose, the necessary thinners, the color palette, the average consumption per square meter, features and drying time, as well as the coloring conditions are noted.

It often happens that it is very difficult to find an identical shade of paint from one manufacturer. Therefore, it is recommended that when buying several cans of paint and varnish material of the same color, make sure that they are all produced by the same company, of the same brand and with the same batch number. Only in this case you can get the desired result.

How to choose?

Oil paints are often used for exterior finishing work. They have a high level of resistance to adverse weather conditions: frost, temperature extremes, sunlight. The paint protects the painted surface.

The composition can also be used for indoor use, but not for painting floors due to its low resistance to mechanical damage.

Before starting outdoor work, you first need to prepare the surface, for which solvents are actively used. They bring the consistency of the composition to the required consistency. The most famous solvents are gasoline, turpentine. Treatment with antiseptics and a primer will allow the coating to lie in an even layer without subsequent peeling and peeling.

Paints protect against increased moisture, prevent the appearance of mold and fungi, damage by pests. A high-quality choice of paint and varnish material will allow you to get a resistant surface to the effects of ultraviolet rays, a bright fresh shade for a long time. The coating usually lasts for at least 5 years.

Oil paints for finishing external surfaces on the modern market are presented in a small variety of color shades. To obtain a certain color, you have to mix several types of paints. Such a composition does not meet environmental requirements due to a pungent chemical odor.

The interior decoration of the premises should be approached responsibly both when choosing design solutions and when choosing an oil coating.

For interior decoration of the house, materials with organic solvents are used. The most commonly used solvents are gasoline, white spirit and kerosene. When working with them, you should observe safety precautions, and use a respirator during the staining process. Over the course of several days, the solvent gradually evaporates, so a sharp unpleasant odor is felt inside the room. It is necessary to ventilate the room until there is no smell left, since there are various toxic harmful impurities in the air at this time.

The main disadvantages of oil paints are the loss of the original color with the acquisition of a yellowish tint and a high fire hazard.

If it is necessary to paint a wooden surface, and the label of the can says that the paint is capable of killing wood pests, you should refuse to purchase it. Due to the content of pest control additives, toxic gases are released into the air.

If the label says “dry abrasion resistance” it means that the surface can be wiped with a dry cloth. And "washable, resistant to intensive washing" means that the surface can be washed with a damp cloth.

If the paint contains vegetable oil, it means that it meets the requirements of environmental friendliness. Usually the percentage is indicated on the label.

Natural paints differ from environmentally friendly and natural paints. They are made from harmless natural ingredients - silicone, methylcellulose, natural wax, shellac, casein and xanthene. The resulting shade depends on mineral, earth, plant and animal pigments.

For floors, you should choose high-strength paints, for furniture - not prone to yellowing, for doors, window frames - standole paints.

Compositions with natural ingredients are much more expensive than synthetic paints, but they are distinguished by a long service life and health safety.

Consumption

When finishing surfaces with oil paints, the average consumption is from 100 to 150 grams per 1 m2. The amount of material consumed depends on the structure and surface roughness. For example, wood absorbs liquid well, including paintwork, so 2 layers of paint are applied to the wooden surface. Also, depending on the degree of preparation of the wall for painting (primer, sanding) material consumption depends.

Manufacturers

Manufacturers such as Finnish Tikkurila, canadian Forester, German Dufa and several others. They manufacture products suitable for harsh climates. By doing this, they have acquired a good reputation. At large industries, materials are produced for all types of work, with a wide range of colors, means for surface preparation for painting.

Manufacturers, along with high quality products, offer an expensive price for it. Paying attention to lesser-known European brands, you can save a lot on paint. These manufacturers include Estonian Vivacolor, Spanish Isaval, German Reesa... They try not to be inferior to their not the cheapest counterparts, but their advantage can be attributed to the low probability of acquiring a fake.

Manufacturers in Russia have just begun to establish the production of high-quality paints and varnishes. Among the most successful manufacturers are "Lakru", "Tex", Kotovsky paint and varnish plant, "Stroykomplex" and "Olivestu"... They are trying more and more often to update and improve the quality of their products.

Tikkurila Is the number one brand in Russia for the production of paints and varnishes. In the production laboratory for new product development, employees create new recipes with unique textures and improved properties of the manufactured products. The manufacturer offers over 20 thousand shades.

Another well-known manufacturer of paints and varnishes is "Lacra", founded in 1996. He specializes in paints, varnishes, water-based paints and varnishes and PVA. In addition, the manufacturer produces and sells primer, parquet varnishes, enamels. The entire range of products meets quality standards and is manufactured on modern equipment according to European technologies.

In Russia, manufacturers of paints and varnishes constitute a large branch of the country's chemical industry. They produce more than 2000 types of paints and varnishes, while these volumes are increasing every year. The expansion of the production capacity of the paint and varnish market per year is from 20 to 40%. This is due to the import and increase in the volume of products manufactured by the Russian branches of foreign companies. Domestic manufacturers are in leading positions in the development of various types of paints and varnishes.

The rich assortment of Russian paint and varnish enterprises is:

paints;
enamels;
fire retardant paints;
putties;
primers;
organic silicate components;
quick-drying varnishes;
solvents;
paints for facades.

Due to the expansion of the range of paints and varnishes due to toughened competition, requirements for labor protection, health and nature, the production of water-borne and powder materials has been increasing recently.

For how to quickly remove old oil paint from a wall, see below.

Having made a decision about painting walls in your apartment, you may have a question, what kind of wall paint is considered the best. Nowadays, a huge assortment of all kinds of repair products is offered, so it can be very easy to get confused and choose the wrong option.

To calculate the paint consumption, you can use the paint consumption calculator.

There are differences in paints for walls, ceilings or floors, they differ in their properties. For example, wall paints should not be taken on clothes after drying. It's good if cleaning can be done simply with a damp cloth, and some paints will have to be wiped off with a soap brush. Therefore, please pay attention to what kind of surface this paint is for before purchasing. In our case, there should be a mark “Wall paint”. If you want to make your job easier and buy a universal paint, then think that its parameters will be worse than that of a specially designed paint.

Types and types of wall paint.

In terms of their composition, paints are divided into:

Silicone wall paints are made on the basis of silicone resins. In the world of paints and varnishes, this is a novelty that has many advantages. The most important advantage is their ability to pass water vapor. Silicone paint is often used for exterior work, as it has the ability to form a surface that repels water.

Alkyd wall enamels are paints, the main component of which is alkyd resin. This paint dries quickly due to oxidation when interacting with air. After drying, a strong film is formed on the surface, allowing steam to pass through. It is good to use alkyd enamel to protect metal surfaces from destruction. It is not recommended to use this type of paint indoors, as it has an unpleasant odor for a long time even after drying.

The main component of oil wall paints is linseed oil (oil). Oil based paints are known for their strength and durability. They can be used both for interior painting and for exterior painting on various surfaces. The main disadvantage is that oil paint takes a very long time to dry. The paint does not allow moisture to pass through, as a result of which the substrate may peel off. Due to a specifically sharp unpleasant odor, oil paints are practically not used for painting walls indoors.

The most economical paints today are water-based paints. They are also called water-soluble or in another way - water-based. Such paint dries very quickly due to the presence of water in the composition instead of a solvent, and also has practically no smell. The properties of the paint depend on the polymers used in the composition, which serve as a binder. The cheapest option is considered to be water-based paint based on PVA glue. This type is suitable for painting in dry indoor ceilings. Paints based on acrylic resin or latex will also be inexpensive. All water-based paints can only be used in dry rooms. Such paints are distinguished by their practicality - dirt is easily removed from the painted surface without being absorbed into the paint structure. Water-borne paints are "breathable", that is, vapor-permeable.

The base for acrylic wall paints is acrylic resins. After drying, they form a tough, hard film due to the bonding properties of the resin. The paint is quick-drying, odorless, abrasion-resistant, and suitable for painting surfaces in damp rooms. If moisture constantly gets on the painted surface, then both the surface under the paint and the paint itself will quickly deteriorate. Some stores stock acrylic wall paint that is grease resistant. Acrylic paints are characterized by bright colors. Among the varieties of flowers, you can easily find the one you need. It is also not difficult to mix paints by color, getting a new shade. Can be tinted with computerized tinting systems. Acrylic paints give the surface a pleasant matt finish.

Latex paints can also be referred to as water-borne wall paints. Their main advantage is considered to be excellent abrasion resistance. To obtain a silky and matt surface, latex paint must be applied in an even thin layer. Most often, latex paints are used when painting wallpaper, textured plaster. When dry, latex paint perfectly retains the surface texture, forming a thin film. Latex paints are distinguished by the degree of surface gloss.

Decorative paints have recently appeared among paints and varnishes. Therefore, their properties and features should be considered separately. With the help of decorative paint, you can easily get different design effects, simulate any surface. You can make your walls look like stone, velvet, silver or gold, or even imitate silk. There are even paints on sale that change the color of the surface at different angles of illumination.

To receive decorative wall paint an aqueous base is used with the addition of minerals and polymers, depending on the desired properties. Decorative paint is the best option for painting walls in living quarters. In addition to decorative qualities, this paint is environmentally friendly. The painted surface will be resistant to abrasion, dust practically does not settle.

To obtain the intended design effect from decorative paints, you can use various painting tools and techniques. To create the necessary pattern and texture, use brushes of different sizes, rollers, metal and plastic spatulas and much more. In the place where you will purchase decorative paint, you can ask for all the necessary information about obtaining decorative effects. Specialty hypermarkets and decorative paint stores usually provide samples of specific paint effects.

Eco-friendly wall paints.

In connection with the increased interest in the ecology of the home (and ecology in general), the so-called "green paints" have gone on sale. When working with them, special ecological paints do not emit harmful fumes at all.

This environmentally friendly paint excludes the addition of such harmful substances as: zinc, mercury, lead, chlorinated phenols, cadmium compounds, as well as other chemicals dangerous to human life. Eco-friendly paints can be safely used in children's for painting walls in the children's room. For people with allergies, this paint will be the best option. You can determine the ecological wall paint by the manufacturer's signs. Each manufacturer has its own mark.

The choice of paint for walls, you need to approach carefully, thinking over the details.

Among the many varieties of paints, there is also oil paint for walls. Thanks to her, the surface will be beautiful and protected from external factors. Unfortunately, with the growth of technological progress and the creation of new types of paints, it began to be forgotten. Not only is it called outdated, it is also criticized for being quite toxic. Nowadays, water-based paints, enamel, acrylic or latex are considered more popular.

In this article, we will take a closer look at the features of oil paint, its characteristics and the principle of application to the surface.

Composition and features of oil paints

The name itself speaks of the main component that is included in this paint. The oil contained inside used to be completely natural and natural. But, these days it is an expensive pleasure, therefore, the composition of the oil paint includes a combined and synthetic drying oil, paired with an alkyd resin. The drying oils themselves contain a suspension of fillers and pigments, which are fine-grained inorganic powder of various oxides, mineral rocks and additives, as well as salts.

To dilute the paint and give it the desired consistency, use the following volatile organic solvents:

Turpentine.
Simple white spirit.
Xylene.
Acetone.
Toluene.

Note! When linseed oil, whether synthetic or natural, reacts with air, the substance begins to harden as a result of oxidative polymerization. A film appears on the surface, after which the composition hardens. This effect serves as the basic principle of oil-based paint as a protective and decorative layer.

Due to the presence of pigments in oil paint, you can get the desired shade or paint the raw material in a variety of tones. Pigments can be organic or inorganic. But for oil products, organic pigments are practically not used.

As for the mineral substances (pigments) that make up the composition, they are divided into two groups:

Achromatic substances are used to obtain gray, black and white. Such substances are lead, titanium and zinc whitewash, black, lithopone, aluminum or bronze powder, soot or carbon. The result is black, gray or white oil paint.
Chromatics are used to form rainbow colors and hues for hikes. The composition turns out to be colorful and pleasant to the eye. Used pigments: chromium and cobalt salts, iron metahydroxide, litharge, cadmium salts, red lead.

Since we are talking about a suspension of oil-insoluble particles, the mixture is thoroughly mixed before painting a wall or other surface with oil paint. The thing is that particles of pigment and filler settle on the bottom over time. When you do not mix the oil paint, the top layer will not be as saturated as the bottom, where most of the pigments have gathered. At the bottom, the composition will be thick and bright in color. If you cover the surface with such paint, then it will look uneven. There will be a bright shade in one place and a dull shade in another. This is not at all the result that any developer needs.

Methods for applying oil paint

You don't need to have some kind of supernatural tool to paint any surface. For work, the standard set used by every painter will fit:

If you work with a brush, then immediately tune in to the fact that the material consumption will be the greatest. However, the brush will penetrate most cracks and grooves, carefully painting over the wall with paint. This is especially useful for those who process loose, porous, complex or corrugated surfaces. It will take maximum time to complete the work.

If you want to cut costs and also speed up the entire process of applying paint to the wall, use a roller. Thanks to the bath for it, you can control the amount of mixture applied to the wall. And the work will go much faster.

In the event that you want to speed up the process as much as possible and minimize material consumption, use a spray gun. With it, any house will turn into a beautiful home in just a few hours. This is professional equipment that will need to be rented. Not everyone can afford to buy such a unit.

Note! Since you will have to pay for rent, spray guns are chosen only when you have to paint a large area, not one room, but several, or even a whole house. Then the costs will pay off.

You need to apply oil paint on a previously prepared surface. Almost any finishing material requires this preparation and cleaning. If you had old finishing material on the wall, such as wallpaper or another type of paint, then all of this will have to be removed. The only exceptions are the walls covered with oil paint. Just make sure it sticks well to the wall.

Scope of use of oil paints

This type of paint is suitable for almost all surfaces. It can handle metal structures, brick, concrete or stone walls. And, of course, a plastered wall would be an ideal coating. It is recommended to use the paintwork outside as they are toxic. If you need to paint the walls inside the building, then use another type of paint or apply it in a limited amount.

In addition to being quite toxic, allergenic and carcinogenic, the formulations have another undesirable property. It is very important for living quarters. What is it about? About vapor permeability. Oil paint does not have it. Walls covered with oil paint do not breathe. It will not work to create a favorable microclimate in the room, since the composition does not support natural humidity.

Note! It is rational to use oil paints inside when the ability to pass steam is not needed. For example, these can be bathrooms, basements, open balconies, kitchens, etc.

It is not recommended to use paint for finishing the bedroom, living room, nursery, glazed balcony. If earlier this was done, since there was no other option as such, nowadays you can purchase formulations that have no toxins and are environmentally friendly. And it's not even about the smell, since there are materials without it. The solvent remains inside the coating and flows inside. This can lead to poisoning.

Advice ! It is necessary to work with oil paint inside especially carefully, using glasses, a respirator and protective clothing. In addition, it is important to leave all doors and windows open for fresh air.

Now the material is especially often used for processing ferrous metal. For example, sports equipment, gas and water pipes, parts of the city's infrastructure. And also it is used for processing wood: benches, gazebos, windows, doors, window sills.

Advantages and disadvantages

No matter how much consumers argue, the scales lean towards product disadvantages rather than advantages. And here we are talking not only about the real shortcomings of the material, but the whole point in marketing policy. We will not consider it, but we will say one thing: each material has its own advantages and disadvantages. Let's look at them to draw our own conclusions.

So let's start with the material shortcomings:

What about the benefits of the products?

You can compare all the pros and cons of the material to understand whether you need this paint or not. Experienced consultants will help you decide which oil paint to choose.

Conclusion

Despite the shortcomings and competition, oil paint on walls and ceilings is being produced and used more and more. In their field, oil products are pretty good and usable. If you use the cons of the material correctly, then they can be compensated. And in order to see how you can paint the surface using oil compositions, we suggest you watch the video:

In modern renovation, the use of interior paint for walls and ceilings is common. The compositions that were used before have long been replaced by new ones, now painting the walls with paint is a durable and reliable way of finishing. But in order for the painting of the walls to meet expectations, it is important to choose the right interior paint. It is not enough to choose the color of the coating for the paint to hold and serve for many years; it is necessary to choose the appropriate type of interior paint depending on the coating material.

Classification of interior paint

There are 3 main types of paint for walls and ceilings. The rest of the options that are found in the hardware store are derived from these paints.

Oil paint for walls and ceilings... The basis of the oil paint is varnish oil. The disadvantage of oil paint is long drying time. In addition, the paint smells strongly, for the duration of staining and until it dries completely, it is necessary to free the room from people and animals. The advantage of oil paint is its low cost.
Alkyd paint for walls and ceilings... The alkyd paint contains synthetic resins. Forming a film on the base, this paint is resistant to moisture and UV rays.
Water-based dispersion paint for walls and ceilings... Water-based paint contains water instead of solvent. Non-toxic, breathable paint, but not resistant to moisture. To eliminate this problem, acrylic is added to the composition of the water emulsion.

How to choose interior paint

The choice of interior paint depends on the substrate to be painted.

Use oil or alkyd paint to paint wooden surfaces. The water contained in the water-based paint will harm the wood. Do not forget to pre-treat the wood, and finish painting with a protective varnish.
If the walls of the apartment are prepared for painting by leveling with concrete or plaster, water-based paint will do. But when painting walls in a bathroom or kitchen, it is better to cover the same base with alkyd paint, it interacts better with water.

For the ceiling, the type of paint is unimportant, but for the convenience of painting the ceiling, purchase a thixotropic paint (it can be of all types). Its peculiarity lies in its density. When stirring, the paint becomes liquid, but as soon as you stop stirring, the solution thickens to the state of sour cream. This is convenient for working with a horizontal ceiling surface. But for walls, you should not choose it: ordinary paint spreads itself under the influence of gravity, in contrast to thixotropic, which will have to be carefully distributed.
Working with a metal surface is similar to working with wood. Metal also does not like water, so oil or alkyd paint is suitable in this case.

Difficulties arise when there is already a coating on the walls and ceiling, and it is impossible to determine its composition. In this case, it remains only to completely get rid of the old paint, and only then apply a layer of new one.

How to apply interior paint

Painting the walls and ceiling is only the final stage. Before you get the brush, you will have to complete the main part of the work, prepare the base for painting. There are several key steps:

Removing the old coating if the repair is not done for the first time.
Aligning the walls. Use cement mortar for large level differences.
Primer application. The primer has several functions. It enhances the adhesion of materials and also reduces the amount of paint wasted. Without a primer, the first layer of paint will be absorbed into the wall without leaving a trace. Pair a primer with paint - acrylic primer with acrylic paint, for example.

Correct the flaws in the base. Restore the cracks in the walls and ceiling using a filler.
Treat the walls with an antifungal and antiseptic solution if necessary.
Paint the finished walls and ceiling using the required staining technique. Wait for each coat to dry before applying a new one.

Painting walls and ceilings with your own hands is not difficult work, but creative and requires patience. Do not rush, wait for each layer to dry, then the coating will delight the eye for a long time and look like freshly painted.
