How to make cobblestone paver molds

Updated February 21, 2017

Pavers are expensive. With quick-drying cement and a mould, you can manufacture your own pavers at a much lower cost than buying them preformed from a home improvement centre. You might have used plaster to make moulds as a child. Now you can employ the techniques you learnt to help you save money.

Select a container large enough to hold the paver you plan to use to form the mould. Make sure the container is at least twice as deep as the paver is thick.

Mix the plaster with the appropriate amount of water. Follow the guidelines on the plaster's packaging, as the amount of water needed will vary by brand.

Fill the container 3/4 full with the plaster mixture. Level the plaster with a trowel.

Place the paver in the plaster face-first until the back edge of the paver is level with the surface of the plaster. If you want your pavers to be thicker, press the paver down further into the plaster. If you want the paver to be thinner, don't press the paver all the way into the plaster. The plaster is thick enough to allow you to create pavers 1 1/2 times thicker than the original paver if you choose. Do not push the paver to the point where the face of the paver touches the bottom of the container, as this will change the way the pavers will look.

Remove the paver from the mould. Allow 24 to 48 hours for the plaster to dry. Once dry, you have an impression of the paver in the plaster.

Tip

To create new pavers, line the inside of the mould with plastic cooking wrap and then fill the mould to the brim with fast-drying cement. Give the cement 24 hours to dry, then flip the mould over to expel the new paver.
