Sika Stamps are a key component of a system of matched concrete and overlayment pattern and texturing tools used to transform the surface of freshly placed architectural concrete into patterns and textures that mimic other building materials such as stone, slate, wood, or brick. Stamped concrete is both easier to install and more cost-effective than these other materials. They create natural appearing, low-maintenance, textured surfaces with the structural strength and wear-resistance of concrete in a wide variety of imprinted patterns. Sika Stamps are marketed under the Sika Scofield LITHOTEX® Pavecrafters® brand.
For existing concrete, a stampable overlay such as SCOFIELD® Texturetop® Pro can be used, that can be textured or stenciled to provide a new surface texture. Stamped concrete should always be colored to achieve the most realistic appearance. There are several ways to color stamped concrete, with the most common being a combination of Sika Scofield's LITHOCHROME® Color Hardener and LITHOCHROME® Antiquing Release Pro.
Another option for adding texture to a concrete surface is to use a concrete surface retarder such as Sika Scofield's LITHOCAST™ Surface Retarder, available in six formulations. The surface retarder is sprayed onto the surface of the freshly placed concrete, where it delays the set time of the surface paste. This allows the surface paste to be washed off later, revealing selected amounts of sand or aggregate on the surface. The final effect can be enhanced by adding Sika Scofield's CHROMIX® Admixtures integral color into the concrete mix.
