Decription:

Protecta® EX 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.
Protecta® EX Mortar will also maintain the acoustic design performance in walls and floors. Protecta® EX Mortar expands approx. 1% by hydraulic action during curing ensuring a very tight seal around the service penetrations and the surrounding opening apertures. Protecta® EX Mortar is easy to sand or drill. The compound dries to an offwhite colour.
