Description and classification
The first lacquer appeared in the XIX century. It was then that the need arose for creating quick-drying paints and varnishes.
Currently, automotive varnish is a two-component composition that allows you to create a durable, resistant to external influences and externally attractive coating. Usually the product already has a certain color. However, it is possible with the help of a color scheme to make the shade that is suitable for a particular car.
Varnish is packaged in cans or spray cans. Car spray cans are very popular in part because of their ease of application.
All existing varnishes can be divided into several types:
- cellulose;
- glyphthalic;
- acrylic;
- metallized;
- acrylic polyurethane;
- polyurethane.
Cellulose and glyphthalic varnishes
The cellulose type of coating appeared before anyone else. For painting cars, it has been used for about 20 years. It quickly dried out, but was flammable, burned out and needed to be polished. Therefore, in the 30s of the last century, it was replaced by glyptal varnish.
Gliftal coating had several advantages:
- better covering properties;
- glossy surface;
- durable coating.
Glifthal lacquers, currently produced, dry much faster than their predecessors, all thanks to their interaction with the hardener.

This type of coating first appeared in the 1960s. It included dye and sparkles (aluminum and bronze). Now such products are made on the basis of acrylic varnishes.
Acrylic car paint dries quickly and forms a shiny coating on the surface of the car. It is applied in several layers over the primer. It takes about 2 hours to fully dry.

Acrylic-polyurethane varnish contains polyurethane and acrylic resins. Use it to create an opaque coating. It is applied in three layers with an interval of 10 minutes. In this case, the humidity level in the room should not exceed 75%.
Polyurethane varnish is the most popular among motorists. It has several advantages:
- creates a strong and resistant to external influences coating;
- has excellent coating properties;
- glitters;
- dries quickly;
- easy to apply.
The disadvantages of this tool include sensitivity to low temperatures.During operation, the room temperature must be at least + 20 ° C.
Polyurethane products are often available in aerosol form. Working with them has some features. One of them is sequence. After applying the first binder layer, wait about 15 minutes. Next, a second layer is applied. After this is the drying period.

The process of applying a glossy or matte spray varnish to a car consists of several stages:
- First of all, it is necessary to clean the surface from contamination.
- The next step is grinding. You need to do it with sandpaper. In this case, the car must be in a place that is reliably protected from dust.
- To close those elements on which there should not be a varnish.
- Degrease the working surface with special tools.
- Now the most important step is staining. The aerosol is applied from a distance of about 25 cm. Sites of a small size are painted in a spiral, and large - crosswise.
- The spray must be applied in several layers. Between them should be an interval of about 10 minutes.
Do not immediately apply a thick layer, otherwise this place will be too prominent. Also, there is no need to rush - it is better to carefully understand the staining technology and adhere to the instructions. If difficulties arise, it is correct to seek the help of specialists.

Now more and more popular is the matte finish. A special matting composition for cars will help to make it. The spray is applied in several layers directly to the paint. After drying, the surface of the car becomes dull. It is worth remembering that neither mother of pearl paints, no chameleon effect will be visible through this type of coating.
Matte varnish in the form of an aerosol has several undeniable advantages:
- It is more durable than conventional paint.
- It fills small cracks in the initial coating, slowing down its corrosion.
- After applying a matte finish, the car does not need to be polished.
- Simple care. It is enough to wipe with a damp cloth.
Car varnish will help protect metal surfaces from destruction, give them shine and protect against external influences. It is recommended to use it as described in the instructions. Only then will it be possible to create a strong and durable coating.
