WAFSHIELD IB is a fluid-applied fire retardant façade coating or vapor barrier protective coating that forms a membrane that expands and contracts. Specifically formulated and designed to apply over all types of substrates from concrete, precast concrete, various types of concrete blocks, stones, plastering, and wood as a waterproofing, air, moisture, and fire barrier with UV resistant protection. It will not crack, crumble, or peel despite exposure to severe weather or total joint movement and retains its elasticity at very low temperatures and in extreme heat, protecting it from water and aggressive atmospheric chemicals.
