W.R. Meadows Airshield LM

SKU: M16388005

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.

AIR-SHIELD LM has been specifically formulated to act as an air/vapour 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 an air and/or vapour 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.

  • Low permeability – prevents the transmission of air and inhibits moisture and vapour 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 clean up
  • 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.
  • VOC content is 0.0 g/L. Produces no harmful odours.
  • Compatible with other asphalt-based emulsion products.
  • May be applied to “green” concrete.
