Things you need

- Paving stone mould
- Sponge (optional)

Nail some scrap lumber together to match the outside dimensions of your paving stone mould. The top of the lumber should be at least as tall as the mould.
Mix some fibre reinforced concrete as indicated on the bag. Use a wheelbarrow or other large container for mixing.
Add concrete colour if you would like coloured paving stones. Concrete colour is available in a wide range of colours to match the surroundings where you will install the paving stones.
Place your square concrete form on a piece of plywood and make sure your mould slips inside easily.
Shovel the concrete into the form to the approximate top level of the mould. Press down firmly on the concrete surface and smooth it with the trowel.
Press the mould down into the concrete until it touches the plywood underneath the concrete.
Wiggle the mould to make sure that the newly moulded paving stones are separate.
Remove any excess that has been forced up above the mould with a trowel. This will ensure that each paving stone is of consistent height.
Add surface texture if desired using the trowel or a wet sponge.
Tap the sides of the form to help separate it from the concrete. Lift off the form.
Gently tap the mould to get it to release from the concrete and lift the mould off. You should have one or more paving stones, depending on how many the mould is designed to make.
Press any additional desired materials like glass beads, broken pottery or other decorative items into the wet concrete.
Apply concrete sealer with a brush when the concrete is hard, but still a little wet. The concrete seal will make the surface harder and tougher.
Allow the sealed concrete to cure for a day or two before laying the paving stones.
Tips and warnings
- Mix your concrete a little dry to make it easier to remove the mould.
- Reserve a little concrete mix to help dry out the mixture if you find your mix is a little wet and sticking to the mould.
