ASTRO PFP FR EX MORTAR

Astro PFP FR 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.

Astro PFP FR EX Mortar will also maintain the acoustic design performance in walls and floors. Astro PFP FR EX Mortar expands approx. 1% by hydraulic action during curing ensuring a very tight seal around the service penetrations and the surrounding opening apertures.

Astro PFP FR EX Mortar is easy to sand or drill. The compound dries to an off-white colour which may be painted.
