BRICKFORM Stampable Overlay (OL-60) is a gray cement premixed blend of special materials that, when mixed with water, forms a thin, Stampable concrete coating. OL-60 resembles gray concrete and is the only stampable overlay that can be used with Color Hardener and Antique Release. BRICKFORM Stampable Overlay is easy to install and forms a tough, durable topping that will withstand years of wear. When used on properly prepared surfaces, BRICKFORM Stampable Overlay will permanently bond to concrete surfaces.
