RockSolid® Stone & Slate provides excellent resistance against water, oil, grease, dirt and rust stains. It is specially formulated for use on dense masonry surfaces such as stone, slate, marble, granite, tile, travertine and limestone. Stone & Slate penetrates below the surface without altering the natural appearance of the substrate. It is UV resistant and application is quick and easy using a 9.5 mm (⅜”) nap paint roller. Stone & Slate is safe to use near grass and plants.
