FP370 FIRESEAL MORTAR

Bostik FP 370 Fireseal Mortar is a dry white powder consisting of inorganic compounds and perlite. When mixed with water, the compounds form a highly thermally insulating fire sealing compound to prevent the spread of fire and smoke through openings in fire rated walls and floors, including openings formed around building service penetrations. Bostik FP 370 Fireseal Mortar expands approx. 1% by hydraulic action during curing ensuring a very tight seal around the service penetrations and the surrounding
opening apertures. Bostik FP 370 Fireseal Mortar is easy to sand or drill. The compound dries to an off-white colour
which may be painted if required. Bostik FP 370 Fireseal Mortar will also maintain the acoustic design performance in walls and floors.
