These are liquid rubbers which are used to create flexible molds and tools for casting, forming, and texturing concrete. Polytek is used to create architectural precast molds, cast stone products, ornamental pre-cast and statuary molds, stamping tools and texturing skins, and rubber block-outs and hole formers. The two-part polyurethane and silicone liquid rubbers can be poured, brushed or sprayed onto any original pattern, regardless of how simple or complex its shape is.
