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 seal to prevent the spread of fire and smoke through openings in fire rated walls and floors, including openings formed to accommodate building service penetrations.
Protecta EX Mortar expands approximately 1% by hydraulic action during curing ensuring a very tight seal around service penetrations and the surrounding construction. Protecta EX Mortar has a rapid setting time and is easy to sand or drill after cure. The compound dries to an off-white colour which may be painted if required.
