Video: Oil And Emulsion Paints
They consist of pigments and fillers, rubbed on drying oil with or without additives. Paints for outdoor use in temperate climates, when coated in two layers on metal, retain their protective properties for one and a half years.
According to GOSTs, oil paints of the following brands are produced (depending on the type of film-forming substance):
MA-021 - on natural drying oil;
MA-025 - on combined drying oil;
GF-023 - on glyphtal oil;
PF-024 - based on pentaphthalic varnish.

E-VA-27APG - white, light pink, light yellow, etc.;

The number 2 indicates that the paint diluted with the appropriate varnish is intended for all surfaces.
Ready-to-use paints are sold packaged in containers of 0.5-3 liters. The labels indicate the purpose of the paint, color, consumption per 1 sq. surfaces for one-layer and two-layer coating, used thinners, etc. These instructions should be strictly adhered to.
To make the paint more liquid, suitable for priming, it is diluted with solvents or thinners: white spirit, turpentine, kerosene, etc.
All brands of paints have the following colors (the hiding power of the paint for the paint consistency is indicated in brackets):
The coverage characteristic should also be considered when choosing a color.
They are neither oily, nor enamel, nor adhesive, they consist of the smallest particles of plastic, evenly distributed in water. When evaporated, its plastic particles form a very strong and elastic film.
Water-based paints have a number of advantages: they are diluted with water, so they are not toxic, the ceiling and walls painted with these paints let water vapor and air ("breathe"), the applied coatings can be washed. They are stronger than glue, but weaker than oil. They are used instead of oil compositions when painting indoors, which helps to save on the cost of paint and varnish. It is better to apply emulsion paints with a paint spray gun or a foam roller.
Stir the paint thoroughly before use, and if it thickens, dilute it with water to a working viscosity, adding baking soda in small portions. Water-based paints can be used to cover primed metal, wood, cardboard and even freshly applied plaster (water will evaporate through the pores of the paint). They are easily applied to the surface with a brush, roller and spray gun. After evaporation of the water, a matt, durable paint finish is formed. The time for light drying of the surface at a temperature of 18-22 ° C is no more than 30 minutes, full drying time - 1.5-2 hours. By adding pigment, paint of any color can be obtained. It is recommended to apply it in 2 layers, the second after the first has dried.
The paints are applied to a clean, dry, well prepared surface. It is better to use "emulsin" as a filler. Plastered and protected surfaces are primed with the same paint that is applied by moving the spray gun first in vertical, then in horizontal directions.
Water-based paints have a high hiding power, which can be increased even more if you add a little chalk and turpentine to the paint - in this case, you get a paste (it is especially good to cover wooden surfaces with it). One kilogram of emulsion paint is enough to cover a surface of 5 square meters.
Finally, water-based paints can be applied to surfaces previously coated with enamel, oil and glue paints. It should not be forgotten that Water-based paints can be applied to adhesive paints only if vitriol and alum primers that destroy the water-based emulsion have not been used. If you are not sure that such a primer was not used, it is better to blur the surface by removing the glue paint, then paint it over and then apply two coats of water-based paint.
The following brands of paints are produced:
The colors are as follows:
Covering rate - from 70 to 220 g / sq.m.. Shelf life - 6 months from the date of issue.
