STI SpecSeal LC Endothermic Firestop Sealant - 29 oz Tube


SpecSeal® LC Sealant is a latex-based, high solids firestop compound. This material, when properly installed, will effectively seal penetration openings and joints against the spread of fire, smoke, hot gasses and water.

SpecSeal® LC Sealant is engineered to adhere well to virtually all construction surfaces and may be applied using a standard caulk gun or by troweling with a standard mason’s trowel or with a putty knife.

SpecSeal® LC Sealant dries to form a flexible shield against the propagation of fire. Its premium latex binder system is totally resistant to water and will not re-emulsify after drying. SpecSeal® LC Sealant is non-halogenated, contains no asbestos or inorganic fibers.
