Cobble Loc is the newest technology in waterborne protection for concrete, brick pavers and surfaces decorated with our Texture Deck. Cobble Loc may be used over most porous surfaces as it has excellent water resistance and marking resistance. Unlike other clear finishes, Cobble Loc has excellent resistance to brake fluid, gasoline, bleach, and acids. Cobble Loc also seals grout and sand in place and prevents ant hills. It allows the applicator to clean and seal pavers on the same day.
