The article provides a comparison of the properties of facade paint and varnish coatings currently used in construction and repair works. Particular attention is paid to silicate paints and varnishes, which are the most promising today according to the fact that their coatings have high vapor permeability and the ability to remove excess moisture from the mineral substrate, thereby determining such performance properties of facade paints and varnishes as reduced contamination, moisture and water resistance , chemical resistance, biostability, etc. The use of a mixture of liquid glass and diatomaceous earth as a binder gives sol-silicate paints additionally high functional properties associated with elasticity and crack resistance. The article presents the results of a study of the resistance of sol-silicate paint and varnish materials coatings to the effects of climatic factors in laboratory conditions using a method developed on the basis of long-term observations of the paint and varnish coatings aging processes in various climatic zones under natural conditions and development of laboratory test regimes taking into account the processes of destruction of paint and varnish coatings during complex impact of climatic factors. The retention of protective, decorative and adhesive properties of sol-silicate paint coatings of various colors was assessed during testing. The expected service life of the studied coatings in the considered climatic conditions was determined.
