Influence of protective and decorative coatings based on sol-silicate paints on the moisture regime of external walls of buildings

The object of research is the humidity regime in external enclosing structures coated with paints different vapor permeability: ash-silicate, silicate, acrylic and silicone. purpose to evaluate effect a paint-and-varnish coating based on developed sol-silicate paint change moisture wall, depending type construction. Comparison effectiveness use various varnishes carried out. properties for finishing walls buildings are described. results calculating influence To assess regime, technique was used determination outside air temperature, decrease which condensation begins fall out walls. This makes it possible compare high accuracy conditions structures. designs presented: aerated concrete (from blocks grades D400, D600), brick, expanded clay concrete. In brick structures, insulation (mineral wool mats, polystyrene) also assessed. course research, thickness layer varied from 0.2 0.6 mm. According article, shown that when using temperature onset likelihood reduced comparison acrylic, silicate silicone paints. Recommendations given choice facade paint, taking into account inside fences designs.
