FIELD: construction.
SUBSTANCE: invention relates to the field of construction, in particular to a method for constructing a fireproof protective layer of roofing coatings. In the method for constructing a fireproof protective layer of roofing, in which, as a primer coating, a first layer of fireproof roofing mastic is applied over the roof covering, or waterproofing, or roofing covering, after hardening of the first layer, apply at least two layers of fireproof roofing mastic with a time of drying between their application. Fire protective roofing mastic contains the following ratio of components, wt %: chlorinated varnish based on polyolefins 40–80; incombustible fine-fiber natural mineral 20–60; surfactant 0.1–2.
EFFECT: technical result of the invention is an increase in the performance characteristics of coatings by increasing the fireproof properties, reducing the spread of fire.
