AIR-SHIELD LM is a single-component, liquid-applied, water-based, polymer-modified air/vapor and liquid moisture barrier AIR-SHIELD LM has been specifically formulated to act as an air/vapor and liquid moisture barrier within the building envelope. It may be applied to most common surfaces and integrated into various wall systems. AIR-SHIELD LM is suitable for both new construction and restoration. Primary purposes include cavity wall and masonry wall construction. AIR-SHIELD LM works equally well as an air and/or vapor barrier on precast concrete, cast-in-place concrete, masonry (concrete block), interior and exterior gypsum board, Styrofoam, primed steel, aluminum mill finish, anodized aluminum, primed galvanized metal, drywall, and plywood. AIR-SHIELD LM cures to form a tough, seamless, elastomeric membrane, which exhibits excellent resistance to air and moisture transmission. Low permeability prevents the transmission of air and inhibits moisture and vapor from passing through porous building materials Highly flexible bridges cracks, which may form in the substrate Environmentally compatible AIR-SHIELD LM is non-toxic User friendly single-component, water-based technology allows for simple, safe use and easy cleanup Liquid applied simplifies detailing and assures a monolithic, seamless membrane when applied to a rough or smooth surface Excellent adhesion remains firmly bonded to the substrate, even when applied over damp VOC content is 0.0 g/L. Produces no harmful odors Compatible with other asphalt-based emulsion products May be applied to green" concrete Self-sealing Nails and fasteners can be used without compromising performance Packaging5 Gallon (18.93 L) Pails55 Gallon (208.20 L) Drums****Available upon special order only.
