Air Barrier C3
AIR BARRIER C3 is a ready-to-use, class 3 waterproof air barrier membrane. It is liquid-applied directly to a variety of approved substrates and will function as a vertical above-grade waterproof air barrier when properly detailed with LATICRETE® Flashing Sealant or LATAPOXY® Waterproof Flashing Mortar.
This non-toxic, water-based, liquid formulation applies seamlessly and does not tear or lose its effectiveness with exposure to weather during construction or while in service.
