Bostik FP370 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 FP370 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 FP370 Fireseal Mortar is easy to sand or drill. The compound dries to an off-white colour which may be painted if required. Bostik FP370 Fireseal Mortar will also maintain the acoustic design performance in walls and floors. The product is certified for use in walls but it is recommended to use Bostik FP320 Fire Batts for these applications. CE-marked Easy to apply Up to 4-hour fire resistance High sound insulation Certified to the latest European standard EN 1366-3 CE Marked to ETAG 026-2 Fire resistance up to 4 hour The fire performance specification of the compound has been derived when the seal has been left to cure for 1 month Classified in walls and floors of concrete, brick, gypsum etc. Suitable for cables, bundled cables, cable racks, cable trays, steel, copper, alupex, plastic pipes and air ventilation ducts High degree of mechanical resistance, the seal is load bearing without reinforcement No priming necessary prior to application in most building material substrates however metal services in contact with the seal must be corrosion protected Easy to apply leaving a very smooth finish Fully set within 1 hour
