Protect and seal Our water glass-based concrete seals ensure quick and easy protection for concrete surfaces. They penetrate deeply into the surface to be sealed and ensure a long-lasting seal and consolidation of the substrate. Besides concrete, many other substrates, such as screed or masonry, can benefit from BV 25800 and BV 19621.
Benefits Environmentally friendly and non-toxic fire protection, colourless and odourless permanent protection against acids and other chemicals. Impermeable to water The treated surface is easier to clean Virus and bacterial load is reduced. Consolidation of the substrate For aged substrates we recommend our BV 19621 sealant, which is based on potassium silicate and is particularly quickly absorbed into the substrate. In contrast, our sodium silicate-based sealant BV 25800 is particularly suitable for fresh concrete substrates. The coating can be applied on small areas by painting, brushing or rolling. The quickest way to protect large areas is by spraying the sealant. The sealants are available in 5 L, 10 L and 20 L canisters, as well as 1000 litre IBCs.
