GRAY LIQUID MEMBRANE FOR VAPOR-PERMEABLE AIR AND MOISTURE PROTECTION
AIR-SHIELD LMP is a water-based, single-component air and liquid moisture barrier that cures to form a seamless, elastomeric membrane. It provides superior resistance to air leakage while allowing vapor transmission, creating a durable drainage plane that prevents liquid water intrusion into substrates. Ideal for both new construction and retrofit applications, AIR-SHIELD LMP is user-friendly, safe to apply, and simplifies detailing with a monolithic, fully bonded membrane.
USES
- Air and liquid moisture barrier for cavity wall and masonry wall construction
- Suitable for new construction and retrofit applications
- Compatible with precast concrete, cast-in-place concrete, masonry (concrete block), interior and exterior gypsum board, rigid foam insulation, primed steel, and untreated plywood
- Ideal for integration into a variety of wall systems
FEATURES
- Resists mold and fungus growth
- Non-asphaltic; meets stringent fire code requirements
- High permeability allows moisture vapor transmission through porous building materials
- Low-temperature flexibility down to -20° F (-28° C)
- Phthalate-free and formulated with natural flame-resistant polymers for low flame spread and smoke development
- Highly flexible; bridges substrate cracks
- UV resistant – gray membrane can be exposed up to six months; black membrane ideal for long-term exposure
- Sprayable with properly configured airless equipment for low-cost application
- Excellent adhesion; bonds to damp surfaces and self-seals around nails and fasteners
- Quick-dry technology unique to the air barrier market simplifies installation
