With a mould for concrete landscaping bricks, you can easily make decorative paving stones at home. Creating beautiful landscaping stones from concrete is simple and will enable you to save a great deal of money. Making a mould for the bricks is an easy project that can be finished in a couple of days, including the time needed for the mould to dry completely. The supplies required are inexpensive and easy to find.
Mix the silicone according to the manufacturer's instructions. The silicone will become the body of the mould used for making casts of landscaping bricks.
Choose a landscaping brick to be the model for the mould. Paint the top and sides of the brick with silicone. Use thick, even strokes to cover the brick. Do not cover the bottom portion of the brick.
Add six or seven layers of silicone to the brick. Allow each layer to dry for 10 to 20 minutes before adding another layer. The silicone should be thickening as each layer is added and dries.
Add an eighth layer and cover the wet silicone with strips of gauze. The gauze will become stiff in the mould and help it keep its shape. Allow the eighth layer to dry before adding two or three more layers.
Place the mould in a cool, dry place to allow it to dry completely. Do not move or touch the mould for at least 24 to 48 hours. When the mould has dried, peel it back from the brick to use it in creating concrete casts.
When making concrete casts, place the mould in a bin of sand to help it keep its shape when the concrete is poured into it. Concrete dye can be used to create casts that match the original landscaping brick or complement house siding.
