SLAVYANKA coating waterproofing — bitumen-polymer mastic

SLAVYANKA coating waterproofing mastic is based on bitumen, polymers and an organic solvent and is applied cold — by roller, spatula or spraying, and on horizontal surfaces by pouring. It is used for external protection of foundations, basements, piles and tanks, on bridge elements and pipelines, and in damp non-residential rooms; it is not used inside residential premises. Work is possible at air temperatures from −10 to +50 °C if the surface is heated above zero. The coating elongates by 1,500 %, withstands bending in frost down to −42 °C and serves from −60 to +110 °C.
