W R Meadows AIR SHIELD LMP

W R Meadows AIR SHIELD LMP
(Liquid Membrane Vapor Permeable Air Barrier)

DESCRIPTION:
AIR-SHIELD LMP is a water-based air/liquid moisture barrier that cures to form a tough, seamless, elastomeric membrane. AIR-SHIELD LMP exhibits excellent resistance to air leakage. When properly applied as a drainage plane, AIR-SHIELD LMP prohibits liquid water intrusion into the substrate.

A low VOC version of AIR-SHIELD LMP is available for those in low VOC areas.

USES:
AIR-SHIELD LMP has been specifically formulated to act as an air and liquid moisture barrier, allowing vapor to pass through it.   It may be applied to most common surfaces and integrated into various wall systems. AIR-SHIELD LMP is suitable for both new construction and retrofit applications. Primary applications include cavity wall and masonry wall construction. AIR-SHIELD LMP 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/BENEFITS:

• Non-asphaltic – designed to meet stringent fire code requirements.
• High permeability – allows the transmission of moisture vapor through porous building materials.
• Highly flexible – bridges cracks, which may form in the substrate.
• UV resistant – gray membrane can be left exposed for up to six months. The black membrane can be exposed for an indefinite period and is ideal for exposed applications, such as beneath rain screen panels.
• 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 surfaces.
• Self-sealing – Nails and fasteners can be used without compromising performance.
• Low VOC content. (Extra-low VOC version also available.)
