Fire-Resistant Sealants

Seal up gaps around pipes, cables and services in fire barriers, preventing spread of smoke and fire, with fireproof sealants, foams, fillers and mastic from Rawlins Paints. Choose intumescent sealants that expand in fire to plug holes, or fillers and compounds to repair cracks and damage to fire barriers and surfaces.

Fireproof adhesive bonds most materials and surfaces together in fire applications, such as sticking fire sponge into place, reflective foils and fire barrier curtains to trusses and beams, and many other fire-stopping projects.
