VAPOR SHIELD is a chemical hardener, densifier, and soluble chloride reducer used on bare concrete before cementitious coating applications. Vapor Shield blocks and reduces vapor emissions through concrete while allowing the concrete to breathe. It blocks hydrostatic pressure up to 20 psi. It does not alter the color of the concrete and does not make the surface slippery. Vapor Shield helps reduce efflorescence on floors. It shortens the green concrete window from 28 days to an average of 5 days. Vapor Shield reduces vapor emissions for surface coating applications such as polyaspartic coatings, epoxy coatings, urethane coatings, as well as carpets, floor tiles, vinyl sheets, and hardwood floor coverings.In conditions where salty air and moisture attack concrete, causing rebar corrosion, Vapor Shield has been proven to stop such corrosion activity. When Vapor Shield is applied to concrete exposed to such conditions, exfoliation or expulsion of chlorides occurs. Vapor Shield reacts with the free alkali in the concrete, forming a silica hydrogel that fills the capillaries inside the matrix. This hydrogel waterproofs and seals the surface after removing all harmful materials for concrete. This process can take up to thirty days or more, depending on the residual concentration of chloride and acid in the capillaries.
