This is a specialized integral colored stamp process. It gives you a brick and mortar look. There is only one pattern in different widths, but several colors to choose from. The mortar is the liquid color hardener used above. Color hardeners allow more color choices than release agents. We do seal this product when it is installed but the sealer wears off because it is porous concrete. After that it is recommended that you reseal this product every 12-18 months to help protect the color.
