Clear, non-yellowing, water-based acrylic coating formulated for use on interior or exterior masonry surfaces. Provides superior hardness and durability. Protects against efflorescence (white, powdery, salt-like deposits) visible on the masonry. Built in flash rust resistance prevents orange staining of surface when applied to masonry containing natural metals. Excellent chemical resistance to de-icing salts, gasoline, oil and weathering. Blush resistant formula will not turn white or haze when exposed to moisture after full cure. Ideal for horizontal and vertical surfaces such as walkways, driveways, pavers, brick, poured concrete, Chattahoochee stone and artificial stone. Not recommended for use on wood, metal, granite, marble, pool decks or areas immediately adjacent to pools or areas subject to hydrostatic pressure.
