Basic principles for choosing spray paints
So that as a result of applying the paint a quality and resistant to destructive effects surface is obtained, the rules of choice should be followed. The dye must match the material on which it will be applied:

The choice of the desired shade should be carried out according to catalogs such as RAL or NCS. Special effects created by paint should be chosen in accordance with the general style of the decorated interior item. The calculation of the amount of material can be carried out according to the data on the consumption of paint per 1 sq. M, you should also take into account the planned number of applied layers.
How to apply spray paints
The second prerequisite for the quality of painting will be compliance with the rules for its application. It is recommended to work in a respirator and goggles - to avoid poisoning. Before painting, you need to prepare the surface: remove dirt from it, degrease it with alcohol or acetone. Surfaces that are not to be painted should be sealed with masking tape. If the material to be painted is porous, it is first treated with a primer. Drains should be removed until they are dry, with a clean rag. Before applying the paint, the can should be shaken several times - the consistency of the paint from this will become uniform. Test staining is performed on a foreign object. The distance from the spray can to the surface to be painted should be about 25 cm. When applying paint, the uniformity of the layer to be created is monitored - exceeding the required amount will cause sagging. To work outdoors, it is better to choose a cloudy, quiet day.
If possible, the surface to be painted should be placed horizontally, if you need to apply paint on a vertical surface, then the coating is performed from top to bottom, this will prevent the paint from dripping. If the paint is applied in several layers, then before applying the next one you need to wait about half an hour. Before you start using the painted product, you must make sure that it is completely dry, this may take about a day. To fix the paint on the surface, you can apply a thin layer of acrylic varnish.
Do not spray paint near a fire - their mixture with air is a highly flammable substance. Work at temperatures above +50 degrees is prohibited. A high-quality surface will be obtained if the soil, paint and varnish from the same manufacturer are used in its creation.
Spray paints should not be given to children as a toy. It can be used only in well-ventilated areas.

The chemical composition of automotive paints may vary, depending on it, the paint is divided into:
- alkyd enamels, characterized by rapid polymerization at ordinary temperature and pressure, used in local repair;
- melamine-alkyd enamels, the application of which requires a high temperature (about 110-130 degrees), characterized by a wealth of shades, the ability to create special effects; the drying time at high temperature caused the use of melamide-alkyd paints in the factory or at specialized enterprises;
- acrylic, the most common, quickly hardening, creating glossy and matte surfaces, resistant to aggressive environments and not requiring varnish coating. Among the disadvantages are the rather high cost of the material.
Aerosol enamels allow you to create interesting effects on a painted surface: in addition to a glossy or matte look, they can look like metal, a chameleon or mother of pearl.
spray paint
The basis of heat-resistant aerosols are organosilicon compounds. In their composition they also contain polymer components and pigments, fillers. Heat-resistant paints are not afraid of exposure to high temperatures, vapors and chemicals. This type of paint is intended for application to ceramic, metal, brick and concrete surfaces; it is used to cover the surfaces of stoves and fireplaces, engines, boilers, and all kinds of building structures. Walls cover it in saunas and pools, bath rooms.
A type of thermal paint, characterized by the ability to accumulate light, is used to decorate road signs, fire protection equipment, certain types of dishes.
It is possible to carry out work using such paint at a temperature not lower than -15 and not higher than + 40C. Drying time depending on humidity and temperature can last about two weeks.
spray paint for plastic
Resistant to chemicals and high humidity, has high wear resistance. Depending on the composition, it can create a surface: glossy, rough or velvety. Hiding power also depends on the composition - the amount of material consumed per unit area.
Paints for plastic are divided into several types:
- polyarylate (polymer), with excellent adhesion, including a primer with enamel qualities;
- abrasion resistant, created on the basis of polyurethane resins, their use allows you to create a glossy surface;
- structural, with good thixotropy, hiding minor surface defects, giving it perfect smoothness;
- Soft touch, a special acrylic-polyurethane composition that creates a velvety surface;
- designed for painting polyvinyl chloride surfaces, well-held on them and providing protection from ultraviolet radiation;
- monadic based on modified alkyd-polyvinyl chloride resins used for application to polyvinyl chloride surfaces.
