Stamped Concrete In the past, imprinted concrete was usually limited to a mason scoring a flagstone-like design freehand, embedding sticks, leaves, and even coffee cans. They pressed them into the surface to achieve the desired effect. Today, the leading edge of concrete is a process called stamping. This process involves “stamping” or “impressing” three dimensional patterns into the concrete. Special stamping tools are used to complete the process. Stamping is done on either freshly poured concrete or on an existing slab that has had a polymer enhanced, fiber reinforced layer of concrete bonded to it. When the stamping is complete, the concrete is then sealed. Which in turn, highlights the colors and provides greater stain and weather resistance. The result is a surface that combines the beauty of masonry with the durability of concrete!
