Firemac FM Firestop Intumescent Sealant

Firemac FM Firestop Intumescent Sealant is a water-based, acrylic sealant utilising a highly reactive formula to reinstate the fire resistance performance of wall and floor constructions where the penetrations of single or multiple services are present. This product expands up to 20 times under an expansion pressure of 7 bar and so can be used as an alternative to pipe collars or wraps for certain pipe sizes.
