Improve the odds with SpecSeal® FastTack™ Firestop Spray. Fast Tack™ Spray is an elastomeric single component silicone/urethane hybrid spray coating designed to provide passive smoke and fire protection in construction joints.

SpecSeal® Fast Tack™ 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. And unlike water-based coatings, cold temperatures won't stop the job.

SpecSeal® Fast Tack™ Firestop Spray is engineered to adhere to common construction substrates and may be spray applied (using airless spray equipment), brush applied (for small applications or touch ups), or flow applied (self-leveling) in linear applications.
