How to Make Molds for Cement Blocks

Making your own cement blocks or pavers can save you a substantial amount of money. You can also make a profit from selling the cement blocks that you produce to stores or other consumers. Before you can make a cement block, you will need to make a mold for the cement block. While the actual dimensions of the mold will vary depending on the size and shape of the blocks you need, the mold making process is simple and can be done using a few inexpensive items.

Wood
Saw
Power drill or screwdriver
Screws
Lacquer

Instructions

- 1
  Decide upon the dimensions of your cement block mold. You can figure this out by using the measurements of your desired cement blocks to create your mold. For example, if your cement block needs to be 6-by-3 inches, you will need to create a mold that is the same size as the block you will need.
- 2
  Cut four pieces of wood based upon the size of the cement blocks you plan to make. Keep in mind that the inside measurements of the wood when it is put together will be the size of the finished cement blocks. The wood should be approximately 2 inches thick, unless you plan to make thicker cement blocks.
- 3
  Assemble the four pieces of wood together into a square or rectangle and measure the inside dimensions. If the inside dimensions concur with the size of the cement blocks you plan to pour, you can begin to construct the mold.

  Screw the pieces of wood together to create the mold. Make sure that the ends of the screws do not stick out into the inside of the mold, or you will have screw indentations in your new cement blocks.
- 5
  Spray lacquer in the inside dimensions of the cement block mold, covering each surface area. This will help ensure that the cement block is easily released from the mold when it is dry. Allow the lacquer to dry thoroughly before you use your new cement block mold.
