FastFlash is a liquid flashing membrane available in gun or rollergrade.
FastFlash can be used in rough openings, to fill joints and seams, to counter-flash waterproofing and air barrier components in new or existing wall assemblies, and to seal around penetrations.
You may use FastFlash independently or with compatible R-Guard products to prevent the unwanted movement of water and air through building envelopes.
