Air-Shield LM
Brand: W.R. Meadows, IncAir-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.
Features- 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.
- 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
- VOC content is 0.0 g/L. Produces no harmful odors.
- Compatible with other asphalt-based emulsion products.
- May be applied to “green” concrete.
- Self-sealing – Nails and fasteners can be used without compromising performance.
