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

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

AIR-SHIELD LSR (liquid synthetic rubber) is an asphalt-free, single-component, synthetic rubber-based liquid air/vapor and liquid moisture barrier. AIR-SHIELD LSR cures to form a tough, seamless, elastomeric membrane, which exhibits excellent resistance to air and moisture transmission.

Uses:

AIR-SHIELD LSR 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 LSR is suitable for both new construction and restoration.  Primary applications include cavity wall and masonry wall construction. AIR-SHIELD LSR works equally well as an air 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:

• Non-asphaltic – designed to meet stringent fire code requirements.
• 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 simple, safe application and easy
• 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 surfaces.
• Low VOC content. Produces no harmful odors.
• Compatible with asphalt-based emulsion products.
• UV resistant – membrane can be left exposed up to four months.
