Cat 5
air and waterproof barrier
Description
Cat 5 is a primary air barrier that’s applied with a sprayer or roller to above-grade structural surfaces prepared with Joint & Seam Filler and FastFlash. Cat 5 produces a highly durable, seamless, elastomeric weatherproofing membrane on exterior sheathing, CMU backup walls, and precast concrete. Proven to prevent water and air penetration of the building envelope in conditions ranging from everyday to the 155-mph winds of a Category 5 hurricane.

OVERVIEW
Cat 5 is a single-component, silyl-terminated polymer (STP) that's applied with a sprayer or roller to produce a highly durable, seamless, elastomeric weatherproofing membrane on exterior sheathing, CMU back-up walls, and pre-cast concrete. Cat 5 is proven to prevent water and air penetration of the building envelope in conditions ranging from everyday weather to the drenching rains and 155-mph winds of a Category 5 hurricane.
Use Cat 5 as the primary air barrier over above-grade structural surfaces prepared with Joint & Seam Filler and FastFlash. Solvent-free. Isocyanate-free. Phthalate-free. Complies with all VOC regulations.
