FastFlash is part of the family of PROSOCO R-GUARD® products developed to prevent the unwanted movement of water and air through building envelopes. Utilize FastFlash as a liquid flashing membrane in rough openings and to counterflash waterproofing and air barrier components in new or existing wall assemblies.

Prosoco R-Guard FastFlash is a gun-grade waterproofing, adhesive and detailing compound that combines the best of silicone and polyurethane properties. This single-component, 99% solids, Silyl-Terminated-Poly-Ether (STPE) is easy to gun, spread and tool to produce a highly durable, seamless, elastomeric flashing membrane.

Use FastFlash as a liquid flashing membrane in rough openings of structural walls. Allows same day installation of windows, doors and other wall assembly, waterproofing or air barrier components. Use FastFlash to adhere, transition and counter-flash through-wall sheet flashing. Suitable for all climates, FastFlash bonds directly to damp or dry surfaces and cures under a variety of weather conditions. 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.

Appropriate for vertical or horizontal, above-grade applications to concrete, masonry, natural stone, structural sheathing, architectural metals, painted metals, glass, PVC, FRP, EPDM and most other building materials. Covers 15-17 square feet per 20-oz sausage.
