FM Mortar

Charcoat Firestopping

CharCoat FM Mortar is a dry white powder consisting of inorganic compounds and perlite. When mixed with water, the compounds form a highly thermally insulating 4 hour 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. CharCoat FM will also maintain the acoustic design performance in walls and floors.

CharCoat FM expands approx. 1% by hydraulic action during curing ensuring a very tight seal around the service penetrations and the surrounding opening apertures. CharCoat FM is easy to sand or drill. The compound dries to an off-white colour which may be painted.

CharCoat FM will also maintain the acoustic design performance in walls and floors. CharCoat FM has great strength and adhesion properties with un-paralleled impact testing and the ability to withstand loads of up to 15kN concentrated load and 500Nm serviceability
