MasonRE R-97 Water Repellent can be applied to brick, grout, unpolished marble, limestone, tile, and other masonry surfaces. Dries clear on surface. Creates an easily cleanable surface for dirt, oil, grime, tar, soil, etc. Due to its water-based composition, masonRE R-97 Water Repellent is odorless and leaves a natural finish (no sheen) on the surface. MasonRE R-97 Water Repellent works by penetrating into the substrate. It is not topical. After being absorbed, masonRE R-97 Water Repellent establishes a powerful chemical network within the substrate pores, keeping moisture and oil out. In addition to keeping treated surfaces dry and making it easy to clean, R-97 does not block the pores, permitting essential vapor transmission.
