Platform stamping tools are tools constructed of a cast aluminum alloy, and are light enough for easy lifting by one man. According to the developer their use can cut costs 50 per cent under conventional walks, floors and patios in California homes. Imprinting of the concrete is done in five steps. After framing, the concrete is poured in the usual manner and struck off. Color topping is then put on the surface of the wet slab. Next, the surface is troweled to the desired texture. Stamping tools are then applied to create the desired pattern.
