Basic knowledge of painting metal products. Metal painting

In most cases, it becomes necessary to paint certain metal products with your own hands. In order to properly perform such an event, it is necessary to take into account some of the nuances of this process.

Consider how to paint a metal surface and what to look for when doing this procedure yourself.

Is it possible to paint metal with your own hands?

Only at first glance it may seem that this work can be done quickly and easily. Smeared more or less suitable paints and varnishes on the surface metal element and everything is ready, but in fact, not everything is so simple. Paints for metal surfaces are very different. It should also be noted that one metal alloy is different from another alloy - this circumstance determines the choice of a suitable paint and varnish material.

Note: Painting metal surfaces according to SNiP provides for a clearly defined technology.
Compliance with all aspects technological process in turn guarantees the quality of such work.

Types of metal surfaces

Different types of paints can react completely differently to a particular metal, so it is advisable to study a little the specifics of metal surfaces intended for subsequent painting:

• So, for example, ferrous metals are best treated with alkyd or oil compounds. and do it better as quickly as possible until the surface reacts with a humid environment, begins to oxidize and rust, and as a result may lose its original margin of safety, especially in open weather-prone areas;
• As for the processing of elements made of galvanized steel, it is a little simpler here, since a zinc alloy applied in a thin layer to the ferrous metal base protects it well from various aggressive influences. But, nevertheless, it will not be superfluous to cover the surface of the element with alkyd-based enamel to increase the service life;
• Non-ferrous metals are best treated not with paints, but with varnishes based on polyurethane and epoxy.

Note: Oil-based paint formulations are not very suitable for treating galvanized surfaces, since their molecular structure does not adhere strongly enough to the zinc alloy base, in turn, this threatens to quickly crack and peel off the paint layer from the treated base.

Stages and technology of painting metal surfaces

The service life of the paintwork directly depends on the quality of the prepared base. As a rule, an unprepared or poorly prepared surface has a lower degree of adhesion due to the increased content of metal oxides and other undesirable chemical compounds, which leads to a significant reduction in the service life of the protective or decorative coating.

cleaning

In order for the coating to last long enough long term the surface to be treated must be carefully prepared. Having spent quite a bit of time and effort on this, you can save a lot on subsequent (repeated) repairs in the future.

Cleaning the surface from metal oxides (rust), grease residues and possible old paintwork is done using special solvents and metal brushes or electric grinding machines with appropriate fittings.

Important to know: In some special cases, when the old paint layer is quite difficult to partially or completely remove, apply suitable types paints and apply them directly on top of the old layer.
The price of such materials is much higher than the usual ones, but it fully justifies itself.
In any case, when it is not possible to completely remove the old layer of paint, it is advisable to purchase suitable formulations albeit a little more expensive, but with a guarantee that the work will be done efficiently and the funds will not be wasted.

After thorough cleaning of the base, it must be primed with special surfaces. Primer compositions adhere strongly to the metal surface, ensuring subsequent, uniform application of paint or varnish.

The soil is applied to the base with the most different ways brushes, manual and electric sprayers, rollers, and in some cases even dip the part into the composition. Depending on the composition of the primer-solution, it is applied, as a rule, in one or two layers. After application, the treated base must be thoroughly dried.

Tip: Preparatory and subsequent painting work is best done in well ventilated but not dusty areas.

Metal coloring

As soon as the surface dries, you can safely proceed directly to the application of the paint itself.

Instructions for applying varnish or paint to metal are practically no different from applying to any other base. It is worth noting only one advantage of the metal - it does not absorb the solution, unlike, for example, and it is quite enough to cover the part with one thin layer of paint.

But in some cases, when a perfectly high-quality surface is required, it is necessary to cover the part in two or three layers, thereby hiding even significant irregularities.

To prevent smudges and streaks that are visually perceptible, it is necessary to apply the layer as thin as possible. It is still better to cover the part with two thin layers, after drying the first one, thus you will not allow inevitable smudges during the work.

The paint is applied with a spray gun. In this case, it is desirable to choose quality tools, which do not leave on the painted surface the villi from the roller and the hairs from the brush.

Conclusion

High-quality painting of metal surfaces today, given the rich assortment of materials to choose from, is quite feasible. Observing technological standards and using only paints and varnishes suitable for specific purposes, you can easily do all the work on painting metal surfaces with high quality and independently. For a better understanding of the technology for performing these works, be sure to watch the video in this article.

Today, painting metal surfaces is very popular, especially among owners. Vehicle. Sudden temperature changes, high humidity, corrosion - all this does not have the best effect on the condition of the metal. Painting of metal products performs two fundamental tasks: it improves external characteristics and protect the material from negative impact factors environment, mechanical loads. In this article, we will look at the methods of painting metal products and the benefits of powder coating.

Large tuning centers offer a whole range of painting services for individual parts of the car, and the application of coloring compositions can be carried out using a variety of technologies. It is customary to distinguish the following methods for painting metal surfaces:

• Using a special paint brush- this method is suitable for painting small metal products with a flat surface;
• Dipping - used for small free-form metal parts;
• Roller– this technology is most effective when painting large-sized metal objects with a flat surface;
• Paint spraying (air and airless)– produced by means of an airbrush during painting large areas metal surface;
• Powder coating followed by polymerization of metal objects– due to its unique technological and operational properties, it can be used on different kind metal surfaces (the most effective and easy to implement method of painting).

Choosing the right paint

Depending on the type of surface, the same coloring composition may interact differently with the metal. That is why it is worth studying in detail the features of metal objects that are intended for partial or complete painting:

• For ferrous metals, oil-based paints are best suited. As for the method of applying the coloring matter, then one should be extremely careful here - the solution must be applied with a brush or roller with quick, sharp movements (otherwise the surface may begin to oxidize, and the layer will lie unevenly and with bald spots). During oxidation, the metal surface loses a number of its operational qualities- the strength, service life of the material and resistance to weathering are reduced.

• Metal surfaces made of galvanized steel do not require additional protection, since the zinc compound (it is applied to the base of ferrous metals) has high wear resistance and resistance to aggressive environmental conditions. That is why alkyd-based enamel mixtures are used for painting such objects.

• As practice shows, non-ferrous metals interact better with epoxy or polyurethane-based paints and varnishes, however, powder coating is also a very effective way.

About the powder coating method

This type of painting is carried out using a special polymer powder with a complex chemical structure. Distinctive features of this composition are high heat resistance, electrical charge and versatility. This is the optimal coloring material for metal objects, which does not require prior dissolution in active type dyes.

Powder dye is often used when painting vehicles and individual components of the car structure, which experience long-term power and mechanical loads. It can also be noted that the cost of powder paint is much higher than that of standard color mixtures.

Powder coating of metal products can be carried out in any enclosed space using specialized devices (for example, using a household spray gun, which is easy to make with your own hands).

In the process of such painting, the metal product experiences the action of electricity - the spray gun blows powder paint through the nozzle, while charging the composition with positive electric charges. Thus, the application of paint is carried out under tension, which makes it possible not only to paint the surface, but also to assign the necessary pigment to the molecular structure.

On the video: an overview of the spray gun for powder coating.

Advantages and disadvantages

Like any material, powder coating has advantages and disadvantages. Let us dwell on the advantages of this composition, which are directly related to its performance:

• Good adhesion to all kinds of metal surfaces.
• Tolerance to sudden changes in temperature, high humidity air and other negative atmospheric factors.
• Insensitivity to the action of water masses and the appearance of primary signs of corrosion and rust - parts painted with powder paint not only acquire metal resistance and an attractive appearance, but also anti-corrosion protection.
• High stability, wear resistance and ductility of painted elements - a metal product with applied protective layer powder paint does not deform during long-term operation, even under aggressive mechanical loads.
• Due to its unique texture, the powder mixture is applied in a uniform layer that covers small surface defects of a metal object.
• This coloring composition performs not only a decorative, but also a protective function - no natural or mechanical effect is scary for objects with powder coating.

Of course, we will not argue that powder paint is an ideal material for painting metal objects. This coating also has a number of disadvantages, the main of which is the high cost and complex technology for applying the composition.

The production of powder paint involves applying the material in three to four layers, which as a result affects the speed painting works, and on their final cost.

How to apply powder paint?

As already noted, powder coloring compositions for metal have a very high cost, but they are characterized by minimal losses during spraying. This criterion is relevant not only for large industrial and production facilities(For example, storage facilities), but also for household painting - in such conditions, the paint is stored not in a specialized, sealed place, but in an ordinary garage or closet.

Do-it-yourself painting of metal using a polymer coloring powder should be carried out at a short distance from the surface to be painted. When working, it is also necessary to monitor the supply of paint, because due to high pressure it can be blown out of the appliance with different speed. It is better to process one part of the surface, and then move on to another - so the paint will lie more evenly and the substance will not volatilize.

Important! If you are going to paint a metal product with your own hands, please Special attention on cleanliness in the room - accumulations of dust can spoil the coating and lead to a violation of the adhesion of the dye to the metal.

Powder coating has excellent technological and operational properties, which compensates for part of the financial costs, and the painted object acquires increased anti-corrosion protection and an attractive appearance. appearance than other modifications of paints cannot boast of.

However, painting metal surfaces with polymer-based powder paints is a very laborious and costly process. If you have enough Money and want to achieve maximum results, seek the help of professional workers.

High-quality painting of metal products implies a number of operations that are mandatory, since the quality as a whole depends on them.

Product pretreatment

The product to be painted must be properly prepared. rust, dirt, old paint- all this should not be! It must be perfectly clean, only then it is suitable for further use.

Chemical degreasing

Proper painting of metal products with a powder suspension is impossible without degreasing. Even if there is no dirt or corrosion on the surface, it is necessary to carry out chemical degreasing and achieve perfect cleanliness.

Coloring

Direct painting begins with the fact that the object is placed in a specialized chamber where the powder is sprayed.

After that, the part with the applied paint moves to another chamber, where the paint is fixed (polymerized). Under the influence electric field the powder turns into a polymer film that penetrates even into the pores of the metal and covers it with an even layer.

Quality control

Good coloring of metal products is impossible without careful quality control. The part with the paint cools down and with the help of a special device it is checked how even the layer was applied.

Prices for the manufacture of a picket fence

The cost of the service includes loading and unloading, standard surface preparation (degreasing), as well as packaging of painted products. In addition, the price of powder coating depends on the volume, specifics of the work, as well as on the features of the metal products themselves. The nature of the surface and area, weight and size, the need for additional processing and other factors are taken into account.

In particular, the price in one direction or another is formed by such features as:

1. flat or corrugated surfaces;
2. flat or bulky products;
3. length of molded products (pipes, profiles, etc.);
4. configuration small items(price depends on its complexity);
5. urgency (urgent coloring is possible on the day of treatment).

Also, the cost is affected by the need for pre-treatment and preparation (cleaning from oxides, drilling technological holes, etc.). The extra charge is applied for urgent works, metallic, antique, wood grain, lacquer painting, as well as for painting in two colors (for example, car rims).

What influences the choice of powder coating

Paint based on polymer powder is characterized by several parameters:

• chemical composition (on a thermosetting and thermoplastic basis);
• type of film former (epoxy, polyester, polyvinyl chloride, polyethylene paints);
• appointment.

All three parameters determine where and what paint is suitable for obtaining the best result. For example:

• Epoxy paints - provide excellent adhesion to the metal surface. They are distinguished by high mechanical strength and resistance to aggressive environments. They are a good dielectric. However, UV resistance is lower than other varieties. They are recommended for indoor use. Apart from decorative effect they provide metal products with reliable anti-corrosion and chemical protection.
• Polyester paints - have high resistance to abrasion, weathering and, unlike epoxy, to the impact sunlight. However, unlike them, they are less resistant to alkalis and have lower dielectric values. Widely used for painting products that are on outdoors under the influence of precipitation. They have a high decorative effect (gloss).
• Epoxy-polyester - they combine many of the advantages characteristic of epoxy and polyester paints: resistance to moisture, salt solutions, dilute acids and alkalis. Primary use - for products used indoors.

Areas of use

This dyeing method is used only for materials that are resistant to the temperature at which polymerization occurs. The lion's share of such products is precisely metal (made of steels, alloys, aluminum, cast iron, etc.) and their list is almost endless. Due to their characteristics and coloring results, powder coatings are widely used in various fields.

• Construction and Decoration Materials- doors, window profile, blinds, fences, gates, roofing materials And so on.
• Home Appliances — gas stoves, dishwashers, dryers, refrigerators, water heaters, washing machines etc.
• Metal furniture, plumbing, kitchen tables and chairs, office and warehouse racks, office partitions.
• Electrical equipment - electrical cabinets, transformers, motor and housing windings, junction boxes, connectors, etc.
• Transport and special equipment - cars (wheels, etc.), motorcycles, excavators, forklifts, etc.
• Sports equipment and more.

Although at first the answer to the question, how to paint metal, it seems not at all difficult, in fact, it is a matter that requires prudence and preparatory actions. And so that the painting process goes without problems, and then paint on metal kept for a long time, it is better to familiarize yourself with the tips that are presented in this article. Here it will be described how to choose the right paint from all the variety that is presented on store shelves. Also for different types metals require paints with different characteristics. And we will try to figure out which paint is right for your purposes.

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

More recently for coating metals used almost exclusively oil paints. But specially designed primers allow you to work with acrylic and many other types of paints. For painting metal paints with epoxy and alkyd bases are also used. However, whatever paint you try to use, make sure that it contains anti-corrosion additives (i.e. ordinary paint will not work). And the recommended choice would be paints that contain rust converters and which lay down in a dense layer after use. Their cost is usually higher than that of oil or alkyd paints, but they will last much longer without losing elasticity.

For each type of metal, there are most suitable species paints. Therefore, the choice of paint according to the rules is one of the components of the answer to the question, how to paint metal.

You can read more about what kind of paint to paint metal in the article on choosing paint for metal.

How to properly paint metal.

Black iron is often used in the construction of metal structures. The disadvantages of this material include the fact that it quickly rusts. Do not delay painting (and therefore additional protection) of such surfaces. In the course are paints with an oil or alkyd base. For better protection surfaces, experts recommend using an alkyd primer containing zinc compounds (chromate or phosphate).

Painting of galvanized surfaces. If the surface is galvanized, its resistance to corrosion will increase significantly. A galvanized roof should serve faithfully for about 15 years, but if you paint it, it will last much longer. And yes, it looks better. For painting metal roof choose alkyd enamel, on a similar surface the enamel is guaranteed to last for several years, unlike oil or alkyd paints.

Painting of non-ferrous metals. Non-ferrous metals are rarely painted, but if such a need arises, then varnishes are used.

Before buying any paint, read the instructions that come with it, it should be painted where it is best to apply it and how to paint the metal.

Preparing metal for painting.

First of all, you need prepare metal for painting. If this is not done, then the result of the work will not be satisfactory. Preparation, in this case, is the removal from the metal of everything that has accidentally stuck to it, etc.

To begin with, you should remove all kinds of garbage (this is usually the easiest). Then, if there is rust or residue old painting- they also need to be removed. It is better to use tools such as:

• scraper;
• emery or wire brush.

Even a sponge, which is used when washing dishes, is suitable for these purposes. After thorough washing, there should be no oily or grease stains, and in general - no dirt or dust. A soap solution is suitable for this, but it is better not to use abrasive products. After the excess is wiped off, rinse the metal again clean water. Wait until dry.

If you have to paint something massive, then the described cleaning process may be excessively delayed. In this case, an oxy-acetylene torch will help. Under the influence of its flame, the old paint will burn, and rust and scale will disappear.

If there is too much rust, then you can apply phosphoric acid solution(known as "rust converter"). First, the surface is smeared with this solution, left for a couple of hours, and in the end, washed with water and dried.

In very advanced cases, when it is not possible to scrape off rust or otherwise remove rust, use paint that contains anti-corrosion additives.

After the surface of the metal is cleaned, you can proceed to priming. This will be a good protection against adverse external influences and against the spread of rust.

As well as in the case of the choice of paint: first read the instructions - for what purposes this or that primer is intended. In general, if a ferrous metal surface is being processed, then the primer should have durable anti-corrosion coating, and for non-ferrous metals - check the adhesion strength in the primer.

And now we go directly to the explanation of how to paint metal. Before painting the main surface, try a small piece - see how the paint lays down. If everything is fine: there are no defects, and it lies well, then you can start painting everything else.

For painting surfaces with a complex, curved shape, a brush is better suited. A standard surface is covered with 3 thick coats of paint, and for curved forms it is recommended to apply 5 to 6 thin layers over and over again.

Choosing the right one plays an important role painting tool, for different types of surfaces it will be different. So for touching up minor areas, an aerosol can is quite suitable. Hold the sprayer at a distance of about 15 cm from the surface, spray the paint in a thin layer. In this case, at least 4 layers are done. Wait about 20 minutes before applying a new one.

The roller is used when painting large and even surfaces. If this method is used, then the paint must be mixed 10% with a solvent. Then 2-3 layers are applied. Any edges and corners are painted with a brush.

Whatever method of painting is chosen, between the application of layers it is necessary to pause for about half an hour. In no case - no more than 3 hours. Otherwise, the paint will harden. If the paint has hardened, then the next coating is carried out only after a month and a half.

Modern technologies for painting metal products are developing rapidly. The use of liquid paints is gradually receding into the background, and most of the manufacturers of steel or aluminum structures are increasingly giving their preference to powder products. Their use guarantees better protective covering capable of lasting for a long time.

Application areas of powder coatings

Powder paints are among the high-tech materials that have unique characteristics that are not characteristic of liquid coloring agents. Their composition consists of coloring pigments, catalysts and resins necessary to form a durable layer. Catalysts play the role of an accelerator for the hardening of the composition. Unlike liquid analogues, powder-based products do not contain a solvent, and air plays the role of a dispersion medium. This reduces their toxicity and significantly saves in their production.

The method of application of these materials is not suitable for all purposes. It has found application in cases where it is necessary to provide reliable protection from the effects of corrosion. In certain cases, this method will help to increase electrical insulation.

In industry, the application of such materials is used to:

• painting of forged products, galvanized and aluminum profiles;
• work with medical and laboratory equipment;
• furniture manufacturing;
• production of household appliances;

This method is also often used in the manufacturing process sports equipment. Often, well-known auto concerns apply the technology for applying such products.

Advantages and disadvantages of modern technology

There are many benefits to powder coating. First, as a result of work, a minimum of waste is generated. Work with the use of high-quality equipment is most effective.

Secondly, the work is carried out in the best sanitary and hygienic conditions. This technique is environmentally friendly. Even inside a specialized oven, which is used to cure paint, the amount of toxins does not exceed the maximum allowable rate,

Thirdly, solvents are not used during operation, due to which shrinkage is reduced, and there are practically no pores on the surface of painted metals.

The use of compounds is considered a fairly economical method of painting. It will take no more than 30 minutes for the layer to harden, resulting in a hard coating on the surface. Thanks to this, you do not need to apply additional layers of material, and during transportation you will spend less money on packaging.

The painted surface is highly resistant to sunlight and moisture. In addition, painted products are less susceptible to direct fire.

Melting stands out among the minuses powder paints at temperatures from 150 °C. Because of this, they cannot be painted with plastic and wood. Apply thin layer composition is problematic. It is important to remember that for the preparation and use of each shade, you will need to use separate containers. It is quite difficult to paint objects with such a coloring agent. non-standard shape. In addition, if scratches still form on the surface, then it will not be possible to remove them locally - you will need to paint a large area. There are no tinting agents in stores, so only standard factory colors can be used.

Classification of powder formulations

Depending on the type of film formed, powder compositions are divided into thermosetting and thermoplastic. In the first case, the coating is formed as a result of certain chemical reactions. In the second - powder coating of prepared metal objects is carried out under the condition of exposure to high temperature, without the participation of chemicals.

Thermosetting compounds are more popular. Epoxy, polyester and acrylic resins are used in their production. Their main advantage is that the painted surface will not melt or deform during secondary heating. This type of paint is suitable for working with items that are designed for use in extreme conditions.

In the manufacture of thermoplastic compounds, the role of resins is played by vinyls, nylons and polyesters. A hard coating is formed upon cooling and final hardening of the layer. When reheated, the paint will melt.

Common paint application methods

Powder coating of various metal products can be performed in several ways. The first of these is air spraying. To do this, the object to be processed should be heated, after which the particles are evenly distributed over its surface. To improve the quality, it is necessary to heat the object to be painted to the highest temperature possible at home.

Electrostatic treatment is the adhesion of material particles caused by electrostatic stress. At the end of the polymerization, the object must be left to dry naturally. This technology is well suited for painting small and simple objects.

The third method is based on the use of flame. For work, special pistols are used, which are equipped with a propane burner. In the process of application, the particles, passing through the flame, melt and fall on the surface of the product in a semi-liquid state. The surface of the product itself does not heat up. As a result of using this technology, the applied layer is uniform and thin. This method is used exclusively for painting large items.

Painting equipment - what tools do you need?

In the powder coating procedure, the application of a coloring agent is not the final stage. In order for the composition to reliably adhere to the surface, the product will need to be heated in a special oven.

To apply the paint, you will need a sealed chamber in which the work will be performed. Spraying will require an electrostatic spray gun. Due to the presence of static electricity, the paint will be evenly distributed over any design.

For the procedure, you will also need a compressor, which should be connected to the painting chamber. On the large productions the number of necessary also includes devices for moving painted objects. This is necessary in cases of painting large and heavy structures.

Color application procedure

Painting of products is carried out in a specially prepared chamber, to which a compressor is connected to pump out air. Dimensional objects are painted in walk-through rooms, and small ones - in dead-end chambers. In more technological production, the paint is applied with special guns controlled by people from outside.

The entire spraying procedure is carried out with a gun. In it, paint particles are charged, after which they are sprayed onto the surface of the product and stick. The algorithm of work is as follows:

1. 1. In a special hopper, the paint is mixed with air. Valves are used to adjust the proportion;
2. 2. The mixture passes through an atomizer equipped with a high voltage source;
3. 3. As a result, positively charged particles are sprayed over the product and quickly set to its surface.

During the operation of the air pumping system, particles that have not had time to charge are sucked out of the chamber. Outside, they fall into a special bunker so that they can be used again or disposed of.

How does the polymerization process take place?

After applying the paint, the product must be placed in an oven, where the part will heat up under conditions of high temperature, and the paint on it will begin to harden. The particles of the composition will melt, resulting in the formation of a film. Immediately after this, the product should cool down. The polymerization procedure will take no more than 20-35 minutes.

Temperature is very important factor for the successful drying of the paint. It should reach 170–200 °C. With its help, the molten particles will fill all the microcracks, forming a perfectly even and durable film.

The coloring composition will begin to acquire all its properties in the process of hardening. It will take at least 20 minutes for the product to cool completely. In this case, the structure should cool naturally, but the use of any devices for cooling is strictly prohibited.
