Perma-Cast Antiquing Release is dusted over the surface of freshly colored concrete flatwork before using a pattern-stamping tool. The release agent prevents the tool from sticking to newly colored, freshly stamped concrete. As the tool is pulled from the concrete the colored release powder is layered into the textured surfaces of the concrete. Upon washing and sealing, the difference in color between the underlying concrete and the release creates a visually attractive, antiqued look to the concrete. The added color gives the appearance of depth.
