MDDRLSR

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. 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.

  • 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.
  • Environmentally compatible – AIR-SHIELD LSR is non-toxic.
  • User friendly – single-component, water-based technology allows for 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
  • Low VOC content (<100 g/L). Produces no harmful odors.
  • Compatible with asphalt-based emulsion products.
  • UV resistant – membrane can be left exposed up to four months.
