This concrete sealer is a high-tech, clear, water-based sealer. The penetrating, inorganic, modified potassium silicate material “fuses” to concrete and appreciably reduces damage to concrete. The unique formula in Permacolour KS500 reacts with the calcium hydroxide in the concrete to form a calcium silicate hydrate gel. This gel is insoluble in water and hardens to densify the concrete, decreasing the moisture permeability and porosity. With the fusion, the substrate actually becomes more resistant to acid and other chemicals. Use in conjunction with Permacolour Repel SS to create the ultimate protection.
