Cat 5 is part of the family of PROSOCO R-GUARD® products developed to prevent the unwanted movement of water and air through building envelopes. Utilize Cat 5 as the primary air barrier over above grade structural surfaces prepared with R-GUARD Joint & Seam Filler and R-GUARD FastFlash. 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 155mph winds of a Category 5 hurricane.
This single component, 98% solids Silyl-Terminated-Poly-Ether (STPE) is roller applied to produce a highly durable, seamless, elastomeric weatherproofing membrane on structural sheathing and back-up CMU walls. Cat 5 can be applied in unfavorable weather conditions to dry or damp substrates. This feature eliminates many weather-related construction delays and accelerates the “drying in” of new buildings. The durable, elastomeric membrane adheres to most surfaces, is immediately waterproof and is compatible with most paints, sealants and self-adhered waterproofing or air barrier components.
Use Cat 5 as part of a building wide R-GUARD Air & Water Resistive Barrier system, or to complement conventional waterproofing or air barrier components. Appropriate for vertical above grade applications to structural sheathing, CMU, architectural metals, painted metals, glass, PVC, FRP, EPDM, and most other building materials.
