Thermoguard Asbestos Encapsulating Smoke & Flame Retardant Coat is a specialist sealer designed to permanently encapsulate rigid, sound asbestos in internal or sheltered locations that are concealed or not subject to mechanical damage. The coating bonds isolated or residual asbestos fibres, preventing fibre release and enhancing fire safety.

Provides certified fire resistance: BS EN Class B s1 d0 and Class O.
