Prevention of undesirable condensation processes in the structure of building materials is possible using vapour barrier coatings based on mastics. The advantage of forming such coatings is their reliable fastening to the surface without the use of additional devices and complex equipment, operational reliability due to the absence of joints. The main attention is paid to the analysis of the dependence of the vapour permeability coefficient of films based on polymer mastics on various production and technological factors - consumption of components in the mastic, layer thickness and application conditions. It is necessary to take into account the viscosity of the composition, the condition of the surface when applying the mastic, and the mode of film formation for effective design of vapour barrier systems based on mastic compositions. Optimisation of work technology contributes to the expansion of the application of mastic compositions in construction, in particular for vapour barrier protection of building structures.
