We are ready to provide a full range of services for car painting. From local painting of cars and painting of separate elements of a body to full painting and polishing of the car.
Increasingly, you can see that cars from the low-cost segment in the pursuit of originality are painted at the factory in bright, eye-catching colors.
Painting cars of this color becomes an art, because the slightest deviation in color or defects in the preparation are immediately obvious.
- our center works with cars of any brands;
- painting works are accompanied by full or partial dismantling of the repaired elements. This significantly affects the final quality of the repair;
- in the presence of insignificant defect of a body the client is offered to carry out only local repair and painting. Thus, only the damaged surface will be exposed to processing, instead of a detail as a whole that, certainly, will help to save money and time expenses.
At your service computer selection of paints and highly skilled colorists. Use of both expensive and middle class paints: Sikens, R-M, Glasurit, 3-M, etc.
Painting the car body: painting technology and recommendations for painting
The paintwork of the car performs an important function of preventing the body from corrosion, protection from the weather and, in addition, giving the car an aesthetic appearance. Given that the body in the car is the most expensive component, then its preservation for the owner is a priority.
Next, consider the most common cases in which you need to paint cars with the technology of the painting process and recommendations for its implementation.
Option one. Separate removable body parts are required for painting.
Always the simplest option of painting is for removable parts (Photo 1) for a number of reasons. In this case, you do not need to select the transition line from the surface to be painted and the already painted surface. The whole element is painted completely. At painting there is a possibility without special problems to change position of installation of a detail at painting and to expose it optimally, for drawing a paint and varnish covering. With a small area of the removable part, you can not use the painting chamber. For best results, you can use a separate part of the room, covered with plastic wrap.

Option two. Parts of the body that cannot be removed need to be painted.
If there is to be painting of a part of a body (Photo 2), it is necessary to be defined with a transition line. As a rule, it is either a separate element or lines of bends, fractures, changes of the form. This rule only emphasizes the fact that the local painting of the body is very difficult. It is very difficult to paint so that imperceptible transitions from a freshly painted surface to a previously painted one were not visible. Although it is possible. It is necessary to tell that competently made partial coloring with transition is practically impossible to see. The cost of the truth of local painting is a little less than the whole detail, because despite the small size of this case will be more troublesome, but the repair if successful coincidence will be invisible.

Technology of surface preparation and application of paint and varnish.
In this case, consider the beginning of painting work to prepare the surface for the application of primer and so on. Skipping procedures if required by body straightening repairs, editing, puttying and form restoration. These works relate to body repair and will be described in the relevant section.
Surface preparation for car painting
Surfaces to be painted must be cleaned of old paint or well plastered. The surface should be homogeneous without pits and uncleaned areas of old paint. Depending on the stage, the surface can be cleaned with hand grinders. Applying the discs during the initial removal of the old paint and finally the sanding paper on a roller mounted in a drill. After that, the surface is cleaned of dust of old paint and degreased with solvent.
Additionally, I wanted to say about the putty. The layer of putty more than 1-2 mm is not acceptable, from putty it is impossible to “sculpt” a body, it is intended only for restoration of correctness of a surface, instead of for construction from it of new elements. In a thick layer of putty, there is a high probability of internal stresses, cracking, and as a result, damage to the paint after painting.
Body primer.
The primer is applied directly to the putty or on steel and galvanized tin. Before applying the primer on an aluminum or plastic surface, we recommend pre-applying a specialized primer and only then apply a second coat of primer for painting cars. After applying the primer, wait for complete drying from 2 hours to 24 hours, depending on the type of primer and drying temperature.
Choice of paint for painting a car
One of the most important, but not the last component is to contact a company that has a reputation in the market for the selection of paint, or rather to turn to a highly qualified specialist. Computer selection is complacency. The computer according to the car code gives out only the formulas put in it (6 grams of blue plus 3 grams of yellow plus 1,7 average grain, etc.), and does not carry out the spectral analysis with decomposition on components and features of paint of your car. The color should be proved by the colorist, on the faded sample from the car, looking at the prepared paint and paint on a car. And the colors should be compared in the light of a special lamp day / evening light. It is from his experience that the approximate similarity of the repair paint to that of your car depends.
Before painting, you need to make a test spray of the paint that you bought or are going to buy. And here begin the nuances to which special attention should be paid. So the colorist in the paint store sprays at a pressure of 2.1 bar in the gun, and you or the painter in the service will charge the gun 2.5 bar – the color will be lighter. The colorist made the spray from a distance of 20 cm, and you or the painter from 40 cm. The nuances of the mass and everything when painting are important.
Painting the car body
Painting can be carried out as one-component, ie directly drawing on a first coat and all, or to represent 2 -3 layer paint and varnish covering usually characteristic of metallic color. Currently, most cars use multilayer coatings, which are the most durable, chemically resistant and highly aesthetic. After applying the paint, in the case of one-component paints, it is considered complete immediately after painting. In the case of multi-layer paints, the paint is coated with varnish. Drying of paint depends on its type and drying temperature, it is specified in the instruction which is applied to paint.
Since the applied paint is the color background for the body of your car, the problems that arose during its application are the most significant in the whole painting process. The following are the main possible defects and signs in which they could occur
Protruding stains from putty (Photo 3)
- Too much hardener in the putty
- Poorly mixed hardener in the putty

Blisters on the surface layer of paint (Photo 4)
- water residues from grinding in corners, edges, bends, cavities and under decorative laths;
- the water used for grinding is too hard;
- polluted compressed air;
- poor insulation of polyester materials;
- high humidity (over 80%);
- condensation due to sharp temperature fluctuations during the dyeing process;
- non-compliance with the drying time.

Shrinkage of the base, possible cracking during drying (Photo 5)
- not dried, not hardened previous layers of applied paints and varnishes;
- too thick layers of previous paints and varnishes.

Incompatibility of paints and varnishes (Photo 6)
- mixing enamels made on different incompatible or partially compatible binders (resins).
- Recommendations for the use of one paint to another must be checked in the instructions for use on the cylinder of the paint can.

Traces of grinding in cover enamel – risks (Photo 7)
- sanding the previous primer with sanding paper of inappropriate (too coarse) grain size;
- insufficient insulation of putty before applying the coating enamel;
- too low viscosity of the coating enamel.

Poor spreading (shale surface) (Photo 8)
- inappropriate (too high) viscosity
- inappropriate application technology, operating temperature
- use of an unsuitable solvent
- inappropriate gun – spray (nozzle), pressure

Leaks (drops of dripping paint) (Photo 9)
- unsuitable – too low viscosity, spray technology, intermediate exposure time in air and application thickness
- inappropriate gun – spray (nozzle), pressure
- too cold material, base or too low temperature in the room
- use of unsuitable solvent or hardener

Formation of depressions with a large area (craters) (Photo 10)
- remnants of wax, fat, silicone
- contaminated compressed air due to condensate or oil residues
- use of silicone polishes or aerosols
- insufficiently cleaned surface before applying paints and varnishes

The final stage in a multilayer coating is the application of varnish. Apply at least one layer, but more layers will only improve the appearance and performance of the paint. Colorless coatings smooth and create the effect of a smooth transition between areas with old and fresh coating.
General recommendations for painting and after it
After the final painting, the car should not be washed for a month if it is winter time and at least two weeks in summer. To prevent scratches and abrasions on painted surfaces.
To attention. It is always easier to choose darker tones of paints than light ones. Selecting paint for lighter body tones is a difficult task. Therefore, the greatest success should be expected if the car has a dark color.
Memo about safety when carrying out works on painting of a body.
When carrying out peeling and painting works use means of protection. Special clothing, gloves, goggles, respirator.
Price – quality when painting a car
If you want to achieve factory quality, know that you need experience. No one is saying that you end up not getting it, but how much material time and effort you will spend on it is a big question.
Also, do not save on sharing the work, that is, order the paint yourself and deliver it to the painter. The painter can always say: “Here, they say, what paint you brought – that’s the result!” It is better to show the defect to painters and ask: “How much does it cost not to be seen?” Not surprisingly, but more reliable. Then the quarrels between painters and paint sellers will disappear, and you will be like a runner between them! Demand will be from the end result and from a specific person.
In conclusion, it is necessary to tell the capital truth about painting a car, that it is first of all a difficult choice: the price – quality, and then technical questions come from here.
