Prosoco Cat 5 Air and Waterproof Barrier, 5 Gallon

Prosoco Cat 5 Air and Waterproof Barrier, 5 Gallon

Cat 5 is a primary air barrier designed for use over 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 every day to the 155-mph winds of a Category 5 hurricane.

Advantages:

• Silane functional polymer provides superior long term adhesion, crack bridging and weathering characteristics. Self seals fastener penetrations.
• Bonds to most common building materials without priming to produce a durable, weatherproof membrane. Easy to repair if damaged.
• Will not tear or lose effectiveness when exposed to weather during construction.
• Bonds and cures in wet weather and on damp substrates.
• May be fully exposed to UV and weather for up to 12 months depending upon conditions. If longer, contact for inspection.
• Single component – saves time.
• Easy roller application in all climates.
• Breathable. Allows damp surfaces to dry.
• Compatible with most sealants and waterproofing or air barrier components.
• Solvent free. Isocyanate free. Phthalate free.
