Stone Sealer SB is an active solvent based silicone water repellent and impregnating agent for porous masonry surfaces such as concrete, block, brick, and unglazed tile. It enhances colored and stained concrete, decorative stones, pavers and cementitious overlays with no film build. Stone Sealer SB penetrates and chemically bonds deep within the substrate to provide long lasting protection against deterioration or staining due to water conditions.
