Fire Block Specialty Sealant, Gray, 10.1 fl. oz.

Fire Block Sealant is a single-component, non-combustible sealant designed to block drafts, smoke, and fire, capable of withstanding high temperatures and preventing smoke passage in non-rated construction. Use it to fill interior gaps around wires, pipes, HVAC ducts, and vents in wood or steel-framed non-rated structures. This fire block becomes tack-free in about 15 minutes and has a formulation that resists shrinkage and sagging to ensure durability, along with a halogen-free composition. It also provides strong adhesion to concrete, brick, metals, wood, plastic, and cable jacketing.
