Oil based paint In the name of the paint orenamel, and it is necessarily indicated on the packaging (label), designations have been introduced that help to find out the composition of the paint (enamel), its purpose. Paints are obtained on the basis of drying oils, varnishes and enamels - on the basis of synthetic resins. The binder on which the paint or enamel is made is indicated by the index of the letters behind the name. The letters MA denote paints on drying oils from vegetable oils, PF - enamels on pentaphtalic varnishes, GF - on glyphtal varnishes, YES - on oil-phenol varnishes, ML - melamine alkyd resins, MCh - on urea-formaldehyde resins, PVA - based on polyvinyl alcohol, BG - based on polyvinyl alcohol bitumen, AK - based on polyacrylates, MC - based on melamine styrene resins, PE - on polyester resins. The letter is followed by a number. By the first digit, you can judge the purpose of the paint. The numbers 1 and 5 say that the paints are suitable for external and internal work, number 2 - only for painting indoors, 0 - primer, 00 - putty. Paints on drying oils (MA), glyphthalic (GF), pentaphthalic (PF) and oil-phenolic (FA) varnishes belong to the group of alkyd paints. They are among themselves, they can be mixed in various ratios (proportions). Paints suitable for outdoor use should be prepared on pigments that are resistant to fading and on weather-resistant binders. Some pigments - zinc white, ocher, red lead, chromium oxide - do not fade even in bright sunlight.
Oil based varnishHigh quality oilThe compositions are obtained only on natural drying. They paint surfaces for protective and decorative purposes. If the main purpose of painting is to protect the painted surface, the painting is performed with compositions that form a glossy film. When decorating surfaces inside rooms, matte coatings are usually used, which soften the coloration tones and make less noticeable the defects of surfaces previously prepared for painting. waxes, diluted in solvent. Such coatings are beautiful, but their strength is low. When preparing for dyeing with matte compositions of oil paints, the surfaces are primed with linseed oil or paint and dyed at a time with a greasy oil composition to a gloss. At the same time the type of the prepared surface should be uniform. All alkyd paints and enamels are applied by brush or roller, usually in two layers. Paint consumption per 1 square meter of surface (in one layer) on average is about 150 g. Paint consumption depends on color and opacity; for white - not less than 200 g / m².
