Suitable for all climates, FastFlash bonds directly to damp or dry surfaces and cures under a variety of weather conditions. It dramatically reduces surface preparation time by eliminating the need for reinforcing tapes at sheathing joints, inside and outside corners. It simplifies the process of producing watertight details in new or existing construction.
Use FastFlash as part of a continuous, building wide air barrier system, or to complement conventional waterproofing or air barrier components. Use FastFlash to adhere, transition and counter-flash R-Guard SS ThruWall or other through-wall sheet flashing.
Limitations:
- Not for use as a structural sealant
- Not for use in place of appropriate through-wall flashing
- Not for use below grade or in locations designed to be continuously immersed in water
