QUICK OVERVIEW
VaproAirSeal™ an air and watertight single component sealant fills gypsum seams and fasteners in preparation for fluid-applied air barrier
- Improves air and water tightness of fenestration systems; sealing the interior window frame to the window rough opening flashing.
- Air and watertight - bonds to VaproShield materials without primers (or priming).
- Minimum application temperature: 40°F (4.4°C).
- Permanently Flexible - allowing for +/- 50% joint movement.
- Paintable – in two (2) hours
- Emits very low VOCs – contains no solvents.
- Compatibility - Compatible with all VaproShield membranes and accessories.
