Video review of a homemade silicone mold under an artificial stone in the form of tiles 300 * 95 mm for $ 3. Make this shape can be made of silicone sealant and ordinary flour, and also using a piece of board, galvanized profile 28 * 27 mm, screws, screwdriver and finished tiles under the stone. And it seems to me that in this way it is possible to make a good business in the garage, since this product can be used more than once.
