SpecSeal® FastTack® Firestop Spray dries rapidly and cures in the presence of atmospheric moisture to form a durable, flexible, water-resistant shield against the propagation of fire, smoke and combustion byproducts.

Check out this video highlighting one of the key benefits…. As you will see, the water-resistant properties of our product make it the ideal product when firestopping the slab edge. 

SpecSeal® FastTack® Firestop Spray is engineered to adhere to common construction substrates and may be applied using airless spray equipment or with a brush (for small applications or touch ups). As an option, SpecSeal Fast Tack Firestop Spray may also be used as a self-leveling sealant and poured into the linear opening to the required thickness as specified in the individual UL System design.
