Prosoco Cat 5 Air and Water-Resistive Barrier for Rain Screen Construction, 5 Gallon

Cat 5 Rain Screen is a roller-applied air and waterproof barrier that produces a highly durable, seamless, elastomeric weatherproof membrane on exterior sheathing behind open-jointed or vented rainscreen cladding. Use Cat 5 Rain Screen as the primary air and water barrier over above-grade wall assemblies.


  • Silane functional polymer provides superior long term adhesion, crack bridging and weathering characteristics. Self seals fastener penetrations.
  • Bonds and cures in wet weather and on damp substrates.

  • Waterproof on the application and for the life of the building. It creates an unmatched drainage plane.
  • The dark bronze color keeps the backup wall unseen through rain screen joints or vents. Single component – saves time.
