Just like natural and man-made stone, concrete and masonry are porous materials that will start to break down, dust, pit, crack, and/or stain when subjected to weather, water, oil, and UV rays. The only way to prevent damage and deterioration is to protect your surfaces with a good quality sealer. DRYLOK WetLook Clear High Gloss Penetrating Sealer is a non-yellowing, water-base sealer formulated for use on horizontal and vertical masonry surfaces where a high gloss, wet look finish is desired. DRYLOK WetLook Clear High Gloss Penetrating Sealer is a premium quality finish that protects and beautifies stucco, brick, bare or painted concrete, pavers, stamped concrete, and exposed aggregate, as well as natural and artificial stone.
