FastFlash is a versatile, fluid-applied flashing membrane designed for quick, reliable detailing of rough openings, joints, seams, and penetrations in both new construction and retrofit applications. Available in gun- or roller-grade formulations, FastFlash simplifies the process of air and water sealing by providing seamless coverage that cures to a durable, flexible membrane.
Whether you're sealing around windows and doors, counter-flashing existing waterproofing components, or integrating with air barrier systems, FastFlash delivers high-performance protection against air leaks and moisture intrusion. It can be used on its own or as part of a comprehensive R-Guard system to ensure continuity of the building envelope.
Built for durability and ease of use, FastFlash bonds to a wide variety of substrates and remains resilient under tough jobsite conditions—no mesh, no fabric, no hassle.
