Today the distinction alkyd, acrylic, glyptal, perchlorovinyl, polyvinyl acetate, phenolic and polyester primer. Let us consider in more detail each type. Alkyd primer perfectly suited for wood before painting. This primer creates a dense layer of matte color, thereby increasing the final surface color. Dries, this primer for 12 – 15 hours.

Therefore, according to the composition in any case can not blot the surface of ferrous metals. Glyptal primer used for the treatment of surfaces in dry conditions. It is also perfectly suited for the processing of metallic surfaces. Complete drying time is 24 glyptal primer hours. Perchlorovinyl primer applied as a coating of metal, concrete and masonry surfaces. Perchlorovinyl dries fairly quickly, within one hour. But to use such a composition for interior decoration not recommended due to the content in it are harmful to human health. PVA formulations used before applying the paint with the same title.
