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.
- Solvent free. Isocyanate free. Complies with all VOC regulations.
- Silane functional polymer provides superior long term adhesion, crack bridging and weathering characteristics.
- Bonds to most common building materials without priming to produce a durable, structural, weather-tight seal which is not subject to tearing or displacement when subjected to wind loads during construction.
- Will not tear or lose effectiveness when exposed to weather during construction.
- May be exposed to weather for up to 6 months without compromising performance.
- Single component formulation saves time and requires no mixing.
- Easy to gun and spread in all climates.
- Produces an opaque membrane when installed at the recommended 12–15 wet mils to simplify inspection and quality control.
- Bonds and cures in wet weather and on damp
