When applied to a finished concrete floor, old or new, CCI Acid Stains transform an ordinary concrete slab into a luxurious floor resembling marble or glazed stone. Stained and scored, it creates the appearance of expensive flooring, at a fraction of the cost. Each concrete slab accepts the stain in varying degrees of intensity, creating stunning, multi-hued color variations and an uneven surface that looks perfectly aged.
