Liquid Membrane Thin Film Permeable Air Barrier- PDF

W R Meadows Air Shield TMP
Liquid Membrane Thin Film Permeable Air Barrier-DESCRIPTION:

W R Meadows Air Shield TMP is a water-based air/liquid moisture barrier that cures to form a tough, seamless, elastomeric membrane. This product exhibits excellent resistance to air leakage. When properly applied as a drainage plane, and it prohibits liquid water intrusion into the substrate.

USES:
This product has been specifically formulated to act as an air and liquid moisture barrier, allowing vapor to pass through it.   It may be applied to the most common surfaces and integrated into various wall systems. It is suitable for both new construction and retrofit applications.

FEATURES/BENEFITS:

  • High permeability – allows the transmission of moisture vapor through porous building materials.
  • Highly flexible – bridges cracks, which may form in the substrate.
  • UV resistant – can be left exposed for up to six months.
  • 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 a damp surface.

PACKAGING:
5 Gallon (18.93 Liter) Pails

COVERAGE:

Plywood 100 ft.²/gal. (2.45m²/L)
Exterior Gypsum Sheathing 100 ft.²/gal. (2.45 m²/L)
