The gate guarding the car in the garage or the entrance to the yard need regular maintenance and restoration. Door painting is done not only for aesthetic appearance. It is important to protect the metal from destruction due to corrosion. It is necessary to choose the right paint and make the preparation of iron sheets and forged items. At the same time, it is created with its own hands and original look gate.

Scale and rust on iron gates

The word "gate" itself means that the structure is outdoors under the influence of moisture and temperature changes. It protects against illegal entry into the garage and yard. Therefore, the gate must be strong, easy to open. They need to be looked after: lubricate the canopies, cover protective compounds the entire surface.

My friend built his house and the next summer came to me with the question of painting the iron gate. During the year they all lost their attractive appearance, began to corrode. The paint was flaking along the edges and at the joints. Restoration required different designs:

• sheet steel garages;
• forged at the entrance to the yard.

Vadik wanted to do everything with his own hands. I told him the main stages of painting the gate:

1. Clean the structure from dust and dirt, wash it well and dry it.
2. Remove rust.
3. Degrease the entire surface.
4. Coat with metal primer.
5. Apply fresh exterior metal paint.
6. Decorate the gate if desired.

Each of the operations can be simplified by using special means and tools. discussion various options my friend and I got busy.

Sheet metal garage doors

Vadik brought a garden hose with various attachments. First, he washed off the dust and debris with a jet of water. Then I sprayed the cleaning solution. Gates made of sheets had practically no transitions. With an ordinary brush, they walked with him on all planes, washing off dirt, oil stains.

The weather was good. The water with which we washed off the remnants of the solution quickly dried up. Then we had a competition. Vadik cleaned one leaf with a metal brush. The second I cleaned with a drill with sandpaper nozzles.

The dust was removed with a vacuum cleaner. On the manual way panicle and sponge did not bother. My friend is tired brushing.

The primer for metal was applied with their own hands, with brushes. Carefully brushed:

• places of welding;
• around awnings, handles, lock;
• ends;
• sheet joints.

Covered the entire surface. In places of doubt, walked twice. Don't forget the pens. The whole surface was completely dry only the next day. Painted with hammer paint. Used a spray gun.

The walls around the gate were covered with foil. We don't need paint. Sheds were greased with grease. Opened and closed several times iron gate. Then the excess grease was wiped dry. The lock was sealed with tape.

Difficulty cleaning forged elements

The forged gate at the entrance to the courtyard had many twisted and bent elements with large quantity hard-to-reach places. They were near the road and were heavily splashed with mud by passing cars.

If possible, washed them first with a strong pressure of water from a hose. Then the cleaning solution was sprayed. Attached to the drill round nylon brushes. Our wives wash such jars inside. Removed almost all dirt. The rest was removed with water.

Inhibitor and modifier will make it easier to clean the gate

Quickly paint the iron gate

They did not sand the rust in the gate structure with a large number of hard-to-reach places. Vadik asked me to tell him about other easy ways to clean corrosion with your own hands. I took out a pre-purchased two-component anti-corrosion compound from the trunk:

• the modifier enters chemical reaction with iron oxide, and changes its formula to inactive;
• the inhibitor suppresses the processes of connection with oxygen and the formation of corrosion.

The two substances are packaged in different containers and are mixed immediately before use.

After applying the rust modifier, Vadik went over all the surfaces with his own hands with a round metal brush, called the “witch”. He fixed it on a drill and set it to medium speed. For cleaning complex design a metal gate my friend spent a couple of hours.

hammer paint

We produce high-quality painting of iron gates

We covered the base with hammer paint. The two actions could be combined. On sale there are paints, which include modifiers and inhibitors. After application, the surface has a glossy appearance. But in places severely damaged by corrosion, rough spots remain.

Iron gates can be painted with different colors:

• nitro enamel dries quickly, but is aggressive to all other materials and does not last long;
• oil under the influence of moisture quickly collapses and ceases to protect the metal;
• alkyd resistant, but emit toxic substances;
• acrylic is unstable to temperature fluctuations and loses its appearance;
• hammer has an original appearance, resistant to moisture.

We settled on hammer paint. The silicone resin base makes it flexible. She gets into the cracks. Metal pigments and synthetic fibers, after drying, form a solid film on the surface with a pattern of small stains. It can cover even iron that has not been cleaned of rust.

High paint fastness is used in the machine tool industry. There it withstands not only water, but oils, emulsions, hot chips. Appearance kept for several years.

Imitation of different types of forging

For decorative design Vadik and I used paints imitating a textured, forged surface. They were called molotov. They have a golden and silver hue, are yellow and white.

Having picked up the colors according to the theme of the drawing, my friend and I began to paint curls and spirals with thin brushes. Vadik decided to turn the gate into an element of architectural decoration.

Paint used in artistic forging

Since artistic forging products are made from a steel profile, which tends to rust quickly, it becomes necessary to apply protective coating.

Forged products have certain features, namely:

• - they are made of ordinary steel, which does not form oxide film and therefore rusts;
• - they are used and mounted both outdoors and indoors;
• - they have a large number of connecting joints between parts;
• - they are often made from a metal bar that does not have a smooth surface.

These features impose their own requirements on the choice of paint.

1. The paint must contain anti-corrosion agents to prevent rust. If interior forging is practically not affected by atmospheric phenomena, then various visors, weathervanes, gates, fences and other exterior forging experience all the delights of the weather.

2. The paint must be sufficiently resistant to physical impact - i.e. do not peel off, wear out or scratch at the slightest touch.

3. For outdoor products, the paint must be resistant to a wide range of temperatures - not cracking at temperatures below -40 and not spreading at temperatures above +40.

4. The paint must be UV resistant and retain its color in any case.

5. The paint must be non-toxic both during drying and when dry. If for outdoor products, given parameter not too important for forged products at home, this is extremely important. The smell of paint in many causes an allergic reaction, dizziness and nausea. In addition, the painting of products most often occurs in indoors, therefore, for the safety of workers, it must have minimal toxicity in liquid state. a

6. The paint should have good plasticity and be easy to apply. Many joints and welds should be well painted to avoid rust.

7. The paint should evenly lay down on uneven surface.
To give originality to an artistic forging product, “patina” is often applied over the main color - a special coloring matter to give the forged products the effect of antiquity. When applying a "patina", the base paint should not change its properties and lose color.

Coloring process art products from metal comes down to several intermediate steps:

1. cleaning (the best is sandblasting),
2. degreasing,
3. application protective film(phosphating, galvanizing or nickel plating)
4. soil application,
5. application of the main paint and varnish composition of the desired color.

Now many people reduce the process of painting products to two stages - cleaning and applying paint. This has become possible thanks to new dyeing technologies and new paint formulations. Some compositions allow paint to be applied even to a rusty surface, these include Hammerite paints based on alkyd-styrene.

As for the types of painting, they can be figuratively divided into 2 types:
- powder coating, which requires special chambers;
- painting with liquid paints, which are applied with ordinary rollers, brushes or spray guns.

Powder coating requires polymer baking in special ovens at a high temperature in the range of 148-180 degrees Celsius. And since the furnace has a limited space, the spraying of bulky and voluminous forged gratings with a polymer becomes problematic. But at the same time, a strong, even polymer layer is created on the forged product. It is good to use this coloring on large surfaces with a small number of joints and openwork elements, since otherwise the granules do not quite densely fill multi-joints, and the polymer film there will be thin and not very strong, which can lead to rolling of the protective coating in these places when installation.

liquid paints suitable for any surface, but their consumption is much higher, especially when painting large openwork through products (for example, a fence or an “open” gate). Besides liquid paints more toxic. But at the same time, there is a guarantee that all joints and elements will be completely painted over. In addition, some liquid paints, when cured, also form a durable polymer film that is not inferior in quality to powder coating.

Conventionally, paints can be divided into the following:

1.Emulsion paints. This group includes all oil and alkyd paints.
Alkyd paints are paints based on organic solvents. The most common solvent for such paints is white spirit (purified kerosene). Alkyd paints withstand wet cleaning with conventional detergents. They also protect metal surfaces well from corrosion and wear both indoors and outdoors. If you need to get a glossy finish, then again choose these paints. Application alkyd paints justified and when it is necessary to convey to the forged product the full saturation of the selected color. The colors of this group also have disadvantages. They take longer to dry than acrylics and are more toxic.
The best representatives of this family of paints is the Finnish Tikkurila paint.
Our company regularly uses a wide range of paints from this Finnish company.

2.Water-dispersed paints. Including acrylic paints.
The main advantage of such paints is low toxicity and fire safety.

WS-Plast acrylic paint was specially developed by a German company for painting metal surfaces. The resulting paint composition has excellent adhesion to many metal surfaces and solid polymers, due to which the service life of such coatings can reach 6-8 years or more. Most blacksmith companies that produce premium forged products use this brand of paint to color these products. If you need to get matte surface, it is better not to find acrylic paints. About WS-Plast acrylic paints they say that they emphasize the skill of a blacksmith.

3.Nitroenamels.The main advantage of such paints is the speed of drying. But the disadvantages are very significant - high toxicity and the need for perfect preparation metal surface before painting, which is very problematic for forging.

Many companies have appeared on the Russian market offering blacksmith paint with different properties, therefore, knowing what criteria paint for artistic forging should have, choosing the right one will not be difficult.

Nowadays decorative elements from metal occupy one of the leading places in the design of interiors and exteriors. And thanks to the use of forged elements, which are distinguished by their special beauty and originality, metal decorations in design projects become almost indispensable.

One of distinctive features forged metal products is their wear resistance and durability. But, despite this, like any metal products, forged elements are subject to negative atmospheric phenomena, and as a result, the appearance of rust. To prevent such situations, as well as to give them a more spectacular look and match the designer's creative idea, forged elements are covered with special decorative or protective compounds, in other words, they are painted.

How to prepare forging for painting

Before proceeding with painting, it is necessary to thoroughly clean the forged product from rust. As a rule, this is done with an ordinary metal brush. A more expensive, but also better way to clean rust from products is sandblasting.

After cleaning from rust and removing dust and dirt from the product, a primer layer is applied, which subsequently ensures high-quality application and retention of the coloring layer on the metal. When choosing a primer, you should pay attention to the fact that it would be intended specifically for metal surfaces.

Painting options

Painting of metal forged products is conditionally divided into four main varieties:

• Normal (budget) painting;
• Textured (forge) painting;
• Powder coating;
• Electrostatic painting.

Consider the features of each type of painting in more detail.

Regular paint. As a rule, ordinary oil or nitro paint is used to paint forged products. Apply to the product with a brush or sprayer. Differs low, in comparison with others, the price. It has minimal anti-corrosion properties. When used outside buildings, it requires coating with a special anti-corrosion compound to protect the product from rust.

Textured (forge) painting. Textured paint differs from the usual one in its increased anti-corrosion properties, however, for outdoor use it also requires the application of an anti-corrosion coating. Tests show that some species texture paints protect metal from corrosion for 6-7 years, after which the coating must be renewed. The main advantage of textured paints over conventional paints is their decorative properties.

Textured paints give products a rich, refined color and a unique shade. For the most part, they are used for painting forged elements indoors.

Electrostatic painting. The most durable, reliable type of painting forged products, but at the same time the most expensive. Accordingly, really expensive, unique products are subjected to electrostatic painting. It has excellent anti-corrosion properties. Applied at the factory. Not applicable in everyday life.

Powder paints for forged items

The advantages of powder coatings over others are undeniable, they are environmental friendliness, economy and durability. Technology powder coating significantly different from other methods. The name of the paint speaks for itself: painting is done by applying powder on a special resin base to the metal. Advantages of powder paints:

• Wide range of colors and shades;
• High strength and wear resistance;
• The content of only environmentally friendly components;
• Low percentage of material waste during painting;
• No need for special preparation of painted surfaces;
• High anticorrosive qualities.

Like any material, powder coatings have a number of disadvantages:

1. The impossibility of "repainting", which allows them to be used only on finished, solid products;
2. Limitation of application to non-standard forms;
3. Difficulty in application at home.

As a rule, powder coatings are applied to finished goods, such as forged furniture, in the factory

Painting grills and fireplace grates

Special attention should be paid to the issue of painting products exposed to high temperatures. Such products include barbecues, etc. For such purposes, special heat-resistant paints are used that can withstand a temperature range of 600-8000C. These paints are environmentally friendly, which prevents the release of harmful substances under the influence of high temperatures. These paints include organosilicon enamels and special heat-resistant powder paints. In the factory, the oxidation method, or bluing, is used.

How to paint the gate if you ordered an unfinished structure from the manufacturer or decided to renew the corroded and peeling leaves damaged by corrosion? In the first case, everything is simple. It is enough to remove dust and pre-apply a layer of primer.

Photo No. 1: the procedure for painting the gate with a spray gun

We will talk in more detail about the re-staining of metal doors. From the article you will learn:

• how to clean and prime the surface;
• pick up paint;
• apply a pattern to the gate by airbrushing.

Preparatory work

As we have already said, you need to start work by cleaning the surface from contamination. Choose a method based on the state of the material and budget. Unfortunately, if the metal is rusted to holes, no measures will save it. You will have to completely replace the sashes, this is an excellent reason to buy sliding gates - comfortable, modern, practical.

Surface cleaning

Since the finish coat will lie evenly only on a clean, fat-free surface, you will need to first remove the traces:

• old paint;
• oils and rust;
• dirt and grease.

Budget cleaning method

To inexpensively remove old paint and dirt, you will need:

• conventional spray gun;
• metal brush;
• sandpaper No. 60;
• white spirit or gasoline;
• rag.

You will spend 8-12 hours manually cleaning the sashes. Advantage - in minimal cost. The procedure is as follows.

1. Wash the gate with a stiff brush. Let the metal dry.
2. Remove old peeling paint with a wire brush.
3. Sand the unevenness of the remaining coating with sandpaper.
4. Degrease the surface with gasoline or white spirit.

Important! It is required to clean from rust and traces of old paint not only the sash, but also all fasteners and locking elements, as well as the frame.

Mechanized cleaning of metal from rust

You can paint iron gates after a simpler one, mechanized way cleaning. You will need one of the following tools to work.

Photo No. 2: metal brushes are used to mechanically clean old paint

• Screwdriver with brush head. Easily copes with the task of removing old paint and traces of corrosion. The downside of the tool is that it runs on battery power. The screwdriver is quickly discharged, you will have to wait until the next start.
• Sanding machine. Great alternative sandpaper. The cost of such a tool is small - from 2000 rubles. The equipment is mains powered.
• Bulgarian with a metal brush. Brass nozzles in the form of brushes are suitable for removing old paint. If we are talking For heavy dirt, pick up a brush with interlaced threads. Work with gloves and a mask.
• Sandblasting. The most expensive and difficult cleaning option. To remove dirt and traces of the old coating, the gate is removed from the hinges. If you apply a layer of paint according to the technology on a previously cleaned surface, it will last up to 6 years.

Chemical cleaning

Usually separate chemical treatment do not use. And really to do beautiful gate for a summer residence or country house, it is better to play it safe and remove a layer of old paint before exposure to the sash with a reagent. So you will achieve maximum adhesion of paint to metal.

The ideal composition for removing rust is Hammerite paint and its analogues. Before applying, degrease the surface with white spirit and wash the sashes with acetone. Checking whether the metal is well degreased is simple: attach thin paper to the sash. If the fat spot does not appear on the sheet, proceed to staining.

Rust neutralizer

Now we will describe how to use a chemical wash before finishing the product.

1. Apply the reagent to the surface cleaned with a wire brush. Use a wash with a gel-like consistency - it has the best covering ability.
2. Cover the sashes plastic wrap- the created greenhouse effect will accelerate the process of paint removal.
3. Wait half an hour and remove the old coating with a spatula. Reuse the reagent if necessary.

The choice of paint and primer for the gate

Now we will tell you which primer is better to use and what paint to paint the gate with. It is important that the finish coat meets the following requirements:

• good covering ability;
• enhanced adhesion to metal;
• the absence of components that oxidize iron;
• high moisture resistance;
• high rate of elasticity;
• strength to mechanical stress.

Several types of paints for metal on the market meet these requirements.

• Silicone enamel. Differs in high strength properties and elasticity. Moisture resistant. Adheres well to metal. All silicon-based organic enamels have anti-corrosion properties.
• Alkyd enamel. Elastic and resistant. Suitable for exterior finish. Supplied in a wide range of colors.
• Hammer paint. It is convenient because the coating does not need to be cleaned and primed before application. Provides excellent water and dirt repellency. It is applied from a spray gun under pressure.
• Acrylic enamel. With its help, you can beautifully paint the gate of any type - swing, sectional, retractable. Withstands large temperature fluctuations, is not afraid of moisture and chemical substances, weather resistant.

Popular paint brands

Now consider the most popular brands of coloring compositions for metal.

Metal primer

As you remember, before applying the paint, you will need another coat of primer, which will protect the surface from corrosion and provide better adhesion. finish coat with metal. To work you can use:

• ship minium;
• silver coin;
• phosphating primer VL-02;
• minium metal;
• primer for metal GF-021.

Use a sprayer to apply primer evenly. After that, you can proceed to finishing.

Color selection

Since everyone has different tastes, the shade of the future gate depends only on the preferences of the owner of the garage. The most popular are green, burgundy, brick and blue colors. For ease of choice, we place a palette of shades.

Staining tools

It is better to paint the gate using:

• spray gun - allows you to apply the coating in an even layer, without streaks;
• roller - reduces the time of work, but leaves strips that have to be rolled several times;
• brushes - increases paint consumption, complicates the procedure.

Sequence of work

We paint metal gate sequentially from top to bottom, observing the following recommendations:

• cover surfaces that do not need to be painted with masking tape or tape;
• overlap one layer with another to hide transitions;
• wait for the layer to dry and paint over the dotted missing areas;
• paint over the hinges, grooves and latches with a thin brush;
• apply the second coat after the first one is completely dry (recommended time is indicated on the paint package).

Important! Do not apply more paint than necessary. A thick layer reduces the strength properties of the material. The optimal number of layers is 2.

Temperature regime

Image No. 1: properties of enamels and varnishes

What happens if you ignore advice temperature regime? In 8 cases out of 10:

• the paint will swell;
• the color will turn out dull, with transitions;
• there will be streaks and influxes.

How beautiful to paint the gate?

Beautifully paint the gate allows the method of airbrushing. To work, you need an airbrush - a device similar to a spray gun, but more functional.

Photo #8: This is what an airbrush looks like

Before drawing a picture, stock up on a sketch and paints. Where can I find a sketch? You can pick up an image on the Internet or design it yourself.

Sequence of work.

1. Transfer the contours of the future image according to the sketch. To do this, use paper templates.
2. To convey the depth of the picture, alternate light and dark shades colors.
3. Work out the small details.
4. Cover the drawing with varnish to add shine and realism.

Examples of work performed by the airbrush method are presented below. Such drawings can be applied to retractable, swing and sectional garage doors.
