This product has a foam core with a thin cement-based facing on either side. It is designed for lining domestic showers and bathrooms but makes a useful lightweight backing for mosaics. It can be glued directly to a wall surface with cement-based adhesive, or a timber batten treated with preservative can be glued to the back to allow screw fixing D-rings and wire hangers. On the ground it must be fully supported on a cement or sand bed, as it has little strength and the applied loads must be transferred through to the ground below. The foam edge should be covered either with adhesive or a frame of either timber or metal angle, as it deteriorates when exposed to light.
