Concrete Resurrection Weather Dance Water Repellant is a water based silane-siloxane water repellent product for porous construction materials such as concrete, brick, block, stone and mortar. It forms an invisible protective barrier that bonds to the unsealed concrete, stone or masonry surface by impregnating and chemically reacting with the materials to reduce water ingress. Concrete Resurrection Weather Dance Water Repellant does not add thickness and it is not a topical sealer. It does not make the surface glossy or change the appearance of the surface. Solvent-free Concrete Resurrection Weather Dance Water Repellant is ideal for protecting concrete in harsh winter climates where salt and ice melt chemicals are commonly used, or where there are repeated freeze/thaw cycles.
