Stampcrete System is cast-in-place concrete, integrally colored and stamped with U.S. patented platform/texturing tools to produce a surface similar to natural stone, brick, slate and other natural paving materials. Base color is achieved through integral color pigments in the concrete mix or surface treated with color hardeners. A powdered color release agent is used in the stamping process and insures maximum surface detail while providing a second color for surface highlights and distinctive grout line look. Stampcrete's special acrylic base sealer added in the curing process provides full color depth and richness with maximum concrete protection.
