Blue Shield is a single-component, liquid-applied, water-based, latex copolymer, air barrier and water resistive barrier membrane. Applied by roller, trowel or spray equipment, it cures to form a tough, seamless, elastomeric membrane, which is resistant to liquid water, air leakage and vapour diffusion. In its liquid state, Blue Shield is light blue in colour and cures to a translucent dark blue colour.
- Highly flexible, bridges cracks which may form in the substrate
- Liquid characteristics assures a monolithic, seamless membrane
- Water-resistive (WRB) air barrier membrane. Prevents air leakage and water ingress
- Remains firmly bonded to the substrate even when applied over damp surfaces
- Water-based technology allows for simple and safe application and easy clean up
- Can be sprayed
Blue Shield is used as an air barrier within the building envelope and as a seamless elastomeric membrane. It isw intended to be applied to most common surfaces and integrated into various wall systems in both new construction and restoration. Blue Shield is an air barrier and a water resistive barrier (WRB).
Typical uses are:
- Water resistive/air barrier for EIFS application
- New and existing walls
- Plywood, cement board and glass matt gypsum sheathing, masonry & concrete
- ICF-Insulated Concrete Forms
