FIELD: manufacture of building materials.
SUBSTANCE: invention relates to heat- and hydroinsulation materials suitable for making and repairing various-type roofings, in particular to gluing roll bitumen and bitumen-polymer materials to brick, concrete, metal, wood, ceramic, and other surfaces, as well as for mastic hydroinsulation of construction units of buildings and installations. Bitumen-polymer mastic is composed of. wt %: toluene 31-34, bitumen 30.5-37, thermoelastoplastic 5-11.5, mineral filler (talc) 21-23, resin-colophony 2.5-3.5. Mastic preparation method is also described.
EFFECT: simplified composition and simplified mastic preparation method, achieved compatibility of mastic with a variety of materials, in particular with roofing materials.
