Everbuild Fire Mate Intumescent Sealant Brown C3

The Everbuild Fire Mate Intumescent Sealant Brown C3, available at Trade Counter Direct, is a professional-grade, one-part acrylic emulsion sealant designed for fire protection and acoustic sealing. Rated for up to five hours of fire resistance, this intumescent sealant is suitable for a wide range of applications, including sealing joints, voids, and irregular holes in fire-rated walls, partitions, and around service penetrations. Its advanced formulation ensures both a firm yet flexible seal and effective sound deadening, making it ideal for demanding construction and maintenance environments.

Tested to the principles of BS 476 Part 20 (1987) and detailed in Warrington Fire Research Report No. 144508/B, this sealant reliably swells when exposed to heat, forming a protective char barrier. The product is easy to apply, requires no priming for most substrates, and is suitable for use in joints up to 50 mm wide. Its fast curing and overpaintable properties further enhance its versatility for professional use.
