Fluid applied, vapor-permeable membrane for use as an air and water resistive barrier in above-grade wall assemblies. The product is a one part, moisture curing silane-terminated polyether (STPE). Barrithane VP is a high-solids, low VOC product. It is highly moisture resistant after cure and can be applied over damp substrates. Barrithane VP will not freeze, can be installed at sub-freezing temperatures and resists rain wash-off immediately after installation. The formulation is also fire-resistant, which allows for its use in many NFPA 285 wall assemblies. Barrithane VP is applied in single or multiple coats by roller or brush at 15-25 wet mils over exterior sheathing and 30-50 wet mils over masonry and concrete. Upon cure, Barrithane VP provides a monolithic, fully adhered membrane. 100%-solids, fluid-applied, single-component, moisture-reacted, elastomeric, coal-tar and solvent-free, modified polymer that cures to form a flexible, monolithic, waterproof membrane on vertical and horizontal surfaces. Due to the moisture-reactive and non-gassing properties of the membrane, it provides tenacious adhesion to concrete substrates above- and below-grade, preventing lateral water migration, even with moisture present in the concrete. The inherent toughness and resilience of MiraSEAL and MiraTITE enables it to bridge structural or shrinkage cracks that may develop in the substrate
