Painting a car is important not only in terms of aesthetics, but also in providing anti-corrosion properties, it protects against the effects of precipitation. Sometimes a partial painting of the car is required, and sometimes a complete transformation awaits it. Interestingly designed "steel horse" looks harmonious, stylish, fashionable, elegant. How to paint a car the right way?

Classification of species

Staining techniques are varied. Often, the owner of the transport is faced with the question of which method is better to choose. The difficulty lies in the fact that not the entire surface was damaged, but only its separate section, and it is required to choose a paint and varnish product to match the main paint. It is much more rational to use partial body painting than to do a complete “reset” of the color scheme.

Special techniques have been developed to help resolve the issue.

1. Partial painting of the car body, deep "abrasions" of the affected vehicle. The damaged area is being processed. The service station master will select exactlycolor using a special table. The complex of works includes cleaning procedures, degreasing, grinding tactics.
2. Full refinishing is used when partial painting of the car will not help. Here you will have to tinker. You can choose the aerosol method, the most common due to obtaining a quick result. The explanation is simple: the spray contains paint under pressure, it is easy to spray on the car.
3. Specialists offer a powder method for partial painting of a car or the entire body. This requires a specialized camera.

What do paint and varnish manufacturers offer?

Palette

The master, like a real artist who paints a picture, selects the right range of shades, since there is plenty to choose from. The pigments that make up the basis of the product can be heat-resistant, moisture-resistant, and have other properties. Solvents allow you to achieve the desired consistency. The pigmented particles are bound by the resin, helping to achieve gloss, elasticity and weatherability. A successful result with partial painting of a car is obtained when using acrylic-based enamel paint. The components of the hardener in combination with the dye are mixed in the right proportions and together with the solvent give the expected result. Hardening, acrylic acquires the strength of the polymer.

Alkyd enamels are often used. These coatings improve the performance properties of the body. Additives speed up the processdrying.

Professional Secrets

"Resuscitation" of a car damaged in an accident does not cause problems: it is easy to find a professional center with a coverage restoration service. First, it is worth assessing the extent of the damage, making a choice in favor of partial painting of a car part, or deciding on a complete modernization. The first option is quite laborious, it requires special knowledge and experience from the auto painter so that the tone of the base matches perfectly with the new coating.

Large service workshops are distinguished by the presence of perfect computer programs. This approach greatly simplifies the selection of tones, speeds up manipulations. Neglecting to find a professional can be detrimental to the final result.

Is it possible not to resort to the services of workshops?

How is partial painting done?

To independently paint a car partially (of an element) or completely (of the entire body), you need to have skills in preparing paint and varnish mixtures. The main thing is to prepare well for the labor-intensive process, be mentally prepared for possible incidents, be able to navigate in their elimination, arm yourself with the necessary tools, and decide on the choice of paint. The procedure can be divided into three stages.

Preparations

First, the car needs to be washed. Dirt should not be left with the slightest chance to spoil the new coating. Examine the car for defects, scratches, dents. Atthe need to partially paint the car door or other parts. Not only the car should be prepared, but also the room. It must be clean, dry, ventilated, dust-free. Compositions of paint and varnish products are highly flammable. It is worth remembering this and removing sources of fire. There are still subtleties that play a role in relation to the premises. The importance of preparation cannot be overestimated: it directly affects the final result. The old coating from vehicles is removed carefully with the help of special washes or a nozzle on an electric drill. In the future, the surface is degreased, primed for better adhesion of the composition to the metal.

Nuances of alignment

Puttying will help remove bumps, roughness before partial painting of the door, hood or other structures. It is better to buy a universal putty, easy to use, with classic application recommendations. It is convenient to work with paint spatulas. On the spatula, the amount of putty necessary to cover the defect is collected. Red hardener should also be added here: 2-3 g per 100 g of product is enough. It needs to dry quickly. But do not exceed the norm, otherwise the putty will turn red, and again you will have to think about choosing a shade to get rid of this effect. The hardener is undesirable on metallic, light shades. After puttying, you need to walk the sandpaper over the surface.

About local wing painting

Partial painting of a car fender (withminor damage) is achieved by retouching. For this method, you will need a narrow-profile tool, lint-free rags, paint in a bottle with a brush. For the perfect combination of color with the base, it is better to focus on the factory paint number. Painter action:

• the site is cleaned, degreased;
• wipe dry with a cloth, paint mixture applied with a brush.

Work is recommended to be done in two or three layers, waiting after each time until completely dry. In more difficult situations, the ability to hold a grinder, spray gun, compressor in your hands will come in handy. In extremely difficult areas, the specialist uses straightening. An amateurish approach is extremely inappropriate here. After that, a skin or professional emery is used. Putty is applied to the defect. It dries for about half an hour. After that, the surface must be sanded again. After priming, you can start painting.

Final stage: varnishing

Varnishing creates an imposing image of the "iron horse", makes it original, fashionable. Goals pursued when varnishing the body:

• gloss, gloss;
• extension of protective functionality against chemical and mechanical actions;
• extending paint life.

There are increased requirements for drying: this must occur at a temperature of 60 degrees. The body must be heated to 20 degrees. When partially painting a car with their own hands under normal conditions, in a room with poor ventilation, some self-taught people use a thinner. This makes it possible to obtain a high-quality film. Lacquering can be carried out using the hot technique without recourse to special thinners.

Mistakes of amateurs

In ideal condition, the temperature of the varnish should be 20 degrees. In some services in winter, the varnish is on the floor, which is wrong. Painters recommend the following.

1. The right choice of equipment. It is optimal to stop on a pistol with a nozzle 1, 3 or 1, 4.
2. Competent gun setup. It is important to monitor the air inlet pressure - it must be set according to the manufacturer's regulations. The torch and supply should be opened to the fullest.
3. Solvents, hardeners, additives are selected taking into account the temperature conditions of the room, the dimensions of the object.
4. Precise observance of the proportions of substances in the mixture.

With the observance of application technologies, a qualified approach, optimally selected conditions of spray booths, the result will please, and only memories will remain from the accident.
