## Description

ProsocoR-Guard Fast Flash

## Features

- Waterproof rough openings on new builds and retrofits. It dramatically reduces surface preparation time by eliminating the need for reinforcing tapes at sheathing joints, inside and outside corners.     Suitable for all climates, FastFlash bonds directly to damp or dry surfaces and cures under a variety of weather conditions. Bonds and cures in wet weather, on damp substrates, and tolerates rain immediately after application.     Utilize FastFlash as a liquid flashing membrane in rough openings and to counterflash waterproofing and air barrier components in new or existing wall assemblies.     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.
