Painting a car body element requires the master to have the necessary qualifications, skills and the availability of the necessary tools. The technology for painting large removable parts sometimes involves dismantling. Sometimes it's easier to remove the hood, fenders or doors than to insulate other parts of the body. Painting hard-to-reach or small car parts eliminates the need for such a procedure.

The technology of preparation for painting a car element in the technical center AMS Moscow on the South

Before you start paint body parts their preparation is necessary. Do not paint the area of ​​the car without first washing and drying it. If necessary, remove rust and chipped paint. Experienced craftsmen will do this with a grinder or special fine-grained paper designed for a similar task. The next task will be priming the surface and puttying, and the final step will be degreasing the surface of the part.

Our car service will paint car body parts without loss of warranty.

The main stages of painting one element of the car

In order for the work to be done qualitatively, it is necessary to strictly follow all the stages of painting and follow the technology. After washing and drying, rust and chips should be cleaned. The finished surface is blown with air, degreased with white spirit or acetone, and the dust is collected with a special cloth.
Then follows the procedure of priming and putty. To avoid drips, the primer is sprayed with a thin layer and dried for at least 20 minutes. The putty is applied in a thin layer to the sides and from top to bottom. As a result, the surface is smooth and without bumps. After the above procedures, the surface is ground and re-primed.

Possible problems

Unpleasant incidents arise for a number of reasons: unprofessionalism, lack of special tools or improper use of materials. To avoid this, you should contact the masters with experience and a full-fledged material base. The most common defects in painting:

  • Color unevenness
  • Loss of adhesion
  • bubble
  • Discoloration
  • Solvent bubbles
  • scratches after treatment
  • microcracks
  • clouding
  • Dry spray
  • craters

How is painting done?

Car painting is carried out in several stages. The first stage is preparatory. It includes:

  • removal of plastic parts;
  • removal of rust and old paintwork from a damaged surface;
  • primer of all parts, providing reliable protection against the negative influence of the external environment;
  • coating surfaces with putty.

At the next stage, using a computer program, the optimal shade of paint for cars is selected, after which you can proceed directly to painting.

This step is key. The car body is immersed in a special chamber. It is in it that painting and drying takes place in a stream of air cleaned of dust. This procedure is very economical, since re-painting is definitely not needed, and environmentally friendly.

In addition to direct painting, we are ready to offer you a number of additional services, namely:

  • restoration of various body elements: bumpers, hoods, roofs, etc.;
  • body painting in any color after repair work.

car painting technology

And you need to paint. The time has already come for a complete painting of the car, or a situation has arisen when you need to do it further. Exit? There is always a way out. It consists in painting the car body with your own hands. Don't worry, everything will work out for you. Just before you start painting, practice on the old body parts, which are in abundance around any garages.

Let's start by revealing a "secret" to you. Auto painting technology has general principles of action, it doesn’t matter whether you want to produce or paint in metallic, paint a body part or carry out.

The difference will be only in the selection of materials for painting and the time you spend. Do not forget to include here the material and time for training - training painting. A little more time, a little more materials, but the experience gained is worth it.

So, we will conditionally divide the technology of painting a car into the following areas:

  • Stages of car painting.
  • Car painting process.
  • Vehicle painting technique.

But conditionally, because these areas of action can change or organically complement each other.

Stages of car painting

Preparation of material and equipment. What do you need to paint a car? Painting materials: putty, primer, paint and varnish, depending on the area and your choice of car color. standard.

The main elements of the equipment are: a grinder with circles, a building hair dryer, an airbrush, a compressor, sandpaper, a grinding planer.

Body preparation. This stage includes: washing the body, dismantling everything that does not need painting, repairing parts of the body if necessary, preparing the surface for puttying, puttying, priming the surface.

That's it, your car is ready for painting. But this requires preparation. The instructions for painting a car directly indicate the presence of a perfectly clean place when applying paint and varnish. Here we will make such a spray booth from the garage.

Site preparation. A stage that is rarely mentioned is the preparation of a place for painting. This place is the garage. A standard 3x6 garage is not suitable for full painting, but it is ideal for local painting of body parts. The technique of painting a car completely requires at least a space of 4x6 meters.

We remove everything superfluous and perform a general cleaning of the premises. With a vacuum cleaner and "Dichlorvos" in the summer. Thus, we eliminate the possibility of dust, debris and insects to spoil your car painting efforts during the varnishing stage. Wet the walls, floor, ceiling with water. There is no need for puddles, but there should not be dry places either.

As an option: the garage from the inside, after the full preparation of the body for painting, can be covered with plastic wrap. To do this, you just need to have adhesive tape and a film.

Car painting procedure

Each master has his own procedure for painting a car, but, nevertheless, there are basic principles that should be followed. All removable parts must be removed and painted locally. This applies to doors, optics, handles, moldings, etc. Those. the body of the car must remain "naked".

Painting parts should begin with internal or hidden surfaces. Exterior painting is carried out last, and it begins with the roof of the car.

car painting technique

The technique of painting a car for different types of painting is also no different. If you are using an aerosol can to remove chips and cracks, the instructions for use of the can are given on it.

When painting a car with an airbrush, it is important to follow the general rules of painting technique. They do not differ in complexity, but the quality of the layers depends on their implementation, and as a result, the appearance of the car.

  • for applying paint. Recommended No. 1.4. It all depends on the paint.
  • Compressor pressure selection. As a rule, 2.5 - 3 atm is optimal.
  • The distance of the spray gun nozzle from the surface to be painted is 150-250 mm.
  • Application layers. 2-3 coats of paint are recommended. Application movements should be uniform and it is important not to overdo it with the thickness of the layer to avoid smudges. Otherwise, this place will have to be repainted completely. The intervals between applying the layers should be 15-20 minutes to dry the paint.

After painting, the coating is subject to various influences for several more weeks, despite the fact that the varnish hardens after a couple of days. On average, it is better not to use the car after painting for at least one and a half weeks for optimal paint crystallization and creating a film on the surface. At this time, you can not use brushes for sweeping dust, avoid direct sunlight and precipitation on the coating. If there is no way to meet the deadline, then you should avoid traveling on country roads and over long distances. As for polishing, you can do this procedure only a month after painting. Until then, you can use the usual gentle paint care products containing wax.

Many motorists are wondering when it is possible to wash the car after painting and not harm the paintwork. You can wash the car, and even more so with high-pressure washers, only after two weeks. Someone washes a car after a couple of days, but in this case, there is a high probability of damage to the coating, especially if washed incorrectly. First of all, at least a month you need to exclude detergents with an aggressive chemical composition, you can not use household chemicals. It is advisable to use a soft sponge and clean water at first, it is better if it is flowing. Do not wash the car in the sun, because water drops can become real lenses and heat up certain areas, thus damaging the paintwork.

Here, in fact, such is the technology of painting a car. After painting, in 98% of cases a car is required.

Good luck to you car lovers.

The complexity of the process of painting a car and the time and financial costs associated with it directly depend on the type of paint that is used. What kind of paint can you paint a car on your own, and which one requires special skills and equipment to use? Which paints and varnishes dry quickly, and which form a better finish? Which paint is suitable for full painting, and which is only suitable for minor repairs? Let's deal with everything in order.

Cellulose paints for car painting. Click on the photo to enlarge.

Cellulose paints are a material with a long "experience" in the field of mechanical engineering. The composition of such paints includes a nitro solvent, which evaporates quickly at normal ambient temperatures, so the coating itself dries quickly. In this regard, there is no need to carry out painting in a special closed box in order to avoid contamination of the freshly painted body with settling dust.

Among the disadvantages of cellulose paints are the following:

  • they are flammable, as they are characterized by a low ignition temperature;
  • a single application of cellulose paint on a car body forms a thin film, therefore, for high-quality painting, several layers are required with thorough drying of each of them;
  • cellulose paints quickly lose color brightness;
  • By themselves, such coatings do not have sufficient gloss, therefore, after painting, polishing is also required.

How to paint a car with cellulose paint? The body must be puttied, sanded and primed. Cellulose enamel is diluted with a solvent in a ratio of 1:1 (for the finishing layer - 1:3) and applied using a paint sprayer.

Glyptal varnishes and paints

Glyphthalic car enamel, unlike cellulose, forms a thicker, durable film, and also does not require subsequent polishing. However, glyptal paint dries for a long time: at a temperature of 20-25 ° C, the coating becomes hard in a day, and completely loses its sensitivity to solvents and mechanical stress only after 15-30 days.

Glyptal varnishes can also be dried at a higher temperature (60-80°C), but then there is a risk of damage to plastic body parts. Before painting with glyptal varnish, the surface must be carefully primed so that the adhesion to the paint is stronger. When diluted with a solvent, it must be taken into account that the viscosity of the varnish may vary depending on the ambient temperature. Most often, the degree of dilution varies between 15-35%.

Acrylic car paints

If you are interested in what kind of paint you can quickly and efficiently paint a car, then we advise you to pay attention to acrylic car enamels. After applying this material, the surface is durable, uniform and shiny. Acrylic coatings quickly harden and quickly become resistant to solvents and mechanical damage.

The only negative is the low covering ability, that is, in order to achieve the maximum effect, several layers of enamel must be applied to the body. Acrylic coating is quite self-sufficient, so varnishing is not necessary. But if you want to make the surface perfectly even, and the color even deeper, then 1-2 coats of varnish will come in handy. Before applying varnish, the acrylic layer must be thoroughly dried and sanded with a fine sandpaper.

Alkyd paints

Alkyd car enamels are another option that is attractive in terms of price and quality. The main advantages of these paints are ease of application, good coverage and resistance to chemical and mechanical stress. The disadvantage is the need for long-term drying of the coating due to the fact that a film forms on the surface of the paint almost immediately, slowing down the hardening of the inner layers. This problem can be solved by increasing the drying temperature, as well as adding a special material to the enamel - an accelerator.

Nitro paints

What paint is better to use in order not to completely paint the car, but only to get rid of minor coating defects? The answer is obvious - nitro paint. It dries very quickly, but has poor weather resistance. In this regard, nitro paints are used mainly for current body repairs and require the mandatory application of a finishing layer of varnish.

Paints with a metallic effect

The coating created using metallic paints can be one-, two- or three-layer.

Single layer metallic

The process of applying such paint is similar to painting with melamine alkyd enamels, since it includes varnish. The difficulty of working with single-layer metallics is that if a smudge forms, it is almost impossible to remove it, since a freshly painted body cannot be polished.

Double layer metallic

The mechanism of working with this material is as follows: metallic paint of the required color is first applied to the primed surface, and then varnish. Of course, varnishing is carried out only after the metallic has completely dried, which takes at least half an hour. The only function of the paint here is to give the body a certain color, while the varnish makes the coating weather-resistant, durable and shiny. When using this method, painting is usually limited to two coats (metallic and lacquer), but this number can be higher depending on the covering power of the paint.

3 layer metallic

Examples of three-layer painting are chameleon or white pearl coatings. The painting of the car is carried out according to the following technology:

  1. the body is carefully primed;
  2. the first coat of paint is applied - a primer-tonor, which gives the car a base color;
  3. a second layer of paint is applied, providing the desired effect, for example, mother-of-pearl. It is translucent, so it does not overlap the base color of the body;
  4. varnish is applied.

The quality of the coating will be truly impressive if you find out in advance which paint is best. Metallic or mother-of-pearl, used for painting cars, is characterized by the complexity of the composition and manufacturing technology, so you can only trust well-known manufacturers. Such a car looks expensive and solid, but it is quite difficult to repair it, even if we are talking about small chips and scratches.

Powder paints

Powder paint is a dry mixture, which is sprayed onto a prepared body using special equipment, and then polymerized during heat treatment, forming a strong homogeneous film. Paint that does not get on the body during spraying can be reused, so the losses during such painting of a car do not exceed 2%. Powder paints are a wide range of shades, as well as the ability to create different effects (gloss, metallic, matte surface). Powder enamels of some types melt at low temperatures, so you can paint them not only on the body itself, but also on plastic and glass parts. Painting with powder enamels is carried out only by professionals, which makes it a very expensive procedure, but the high quality and attractiveness of the coating pays off the costs many times over.
