W.R. Meadows Air-Shield LM Liquid Membrane Air/Vapor & Liquid Moisture Barrier 5 Gallon

W.R. Meadows Air-Shield LM Liquid Membrane Air/Vapor & Liquid Moisture Barrier 5 Gallon

AIR-SHIELD LM is a single-component, liquid-applied, water-based, polymer-modified air/vapor and liquid moisture barrier. AIR-SHIELD LM cures to form a tough, seamless, elastomeric membrane, which exhibits excellent resistance to air and moisture transmission.

Uses:

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 applications include cavity wall and masonry wall construction. AIR-SHIELD LM works equally well as 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.

Features and Benefits:

• 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.
• User-friendly – single-component, water-based technology allows for the simple, safe application and easy cleanup.
• Liquid applied – simplifies detailing and assures a monolithic, seamless membrane when applied to a rough or smooth surface.
• Sprayable – with appropriately configured airless spray equipment – low application costs.
• 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.
