Product Offering

VaproLiqui-Flash is a liquid applied Waterproof Flashing material for window and door interfaces. It is designed for use with VaproShield Sheet Membranes in Air Barrier and Weather Resistive Barrier applications.

VaproLiqui-Flash is a unique material formulated to bond without primers to VaproShield membranes and most common wall substrates forming a monolithic, waterproof surface while remaining permeable to water vapor. It allows underlying moisture to escape to the exterior, reducing the potential for mold and decay that is often associated with non-permeable flashings.

Benefits

  • Allows same day installation of windows and doors
  • Bonds directly to damp or dry surfaces and cures under a variety of weather conditions
  • Skins-over in 30 minutes and dries in 4 hours at 70°F (21°C) and 50% relative humidity
  • Suitable for all climates and weather conditions
  • Produces an opaque membrane when installed at the recommended 12 15 wet mils simplifying inspection and quality control
  • May be exposed to weather for up to 6 months without compromising performance
  • Single component formulation
  • No shrinkage. No staining. No yellowing.
  • Breathable – allows damp surface to dry
  • Will not support mold growth
  • Non-corrosive and adds self-sealing properties to fastener penetrations
