Quick Overview
VaproLiqui-Shield is a sprayable/rollable STPE that is solvent and isocyanate free. It is installed above grade on the outside of the wall sheathing and behind rain screen wall cladding assemblies.
VaproLiqui-Flash is a high performance fluid-applied vapor permeable water resistive barrier/air barrier that protects the building envelope by allowing vapor to pass through (breathable) but not air or liquid water
- Forms a seamless, monolithic air and water resistive barrier
- 12 month UV and weather exposure before permanent cladding is installed
- Suited for open joint cladding requiring advanced UV protection
- Solvent and isocyanate-free formulation
- Sprayable and rollable application
- Bonds to common building substrates
- Drying capacity of 21 perms
- Application thickness 20 wet mils
- 20 year material warranty
