You require a cobblestone mold in order to make cobblestones for your patio or pathway in your garden. Cobblestones will be a charming addition to your outdoor area and it will help enhance the beauty of the place. Keep in mind that it is not costly to make cobblestones out of concrete and remember that molds are available at your local home improvement store.

Step 1 – Marking the Spot With Stakes

Determine the spot in your outdoor area where you want to put your cobblestones. Mark the place with the wooden stakes and drive them into the ground in the corners. Use the wooden stakes to mark curves in the cobblestone design as well.

Step 2 – Clearing the Area

Clear away any grass or turf from the area where you want to place your cobblestones. Make sure that the grass is removed from a depth of between 1 and 1½ inches. Do not throw away all the grass, save the best of it to surround the cobblestone pathway.

Step 3 – Mixing the Concrete

Pour the concrete in a wheelbarrow or tub and as you mix it thoroughly, put the concrete colorant that you want. Read carefully the manufacturer’s instructions given with the cobblestone mold to check the quantity of concrete needed, depending on the area on which you want to place the cobblestones.

Step 4 – Molding the Cobblestone

Clean the cobblestone mold by spraying it with water from a garden hose first, before you fill it with concrete. Put the cobblestone mold in one side of the prospective cobblestoned location. Fill the mold with concrete and make sure that you leave nowhere empty. Use a trowel if you find an unfilled gap and use it again to smoothen the surface when the mold is completely full.

Now you need to wait for a few minutes and remove the mold. Clean the cobblestone mold again by spraying water from your garden hose. Put the cobblestone into place and repeat the molding until the cobblestone pathway is ready. Remember to turn the mold slightly, approximately a right angle turn, in order to give the cobblestone the appearance of natural stone. Another useful tip for when using cobblestone molds is that to obtain an ongoing cobblestone pathway you should let one mold touch the one next to it.

Step 5 – Finishing the Cobblestones

Use a gentle hand when finishing the cobblestones. Apply a sand coating to the concrete and make sure that the sand coating is not too heavy. Fill up the joints in the concrete with sand by using a broom.

Wash the cobblestones lightly with water from your garden hose. Lay a thin piece of plastic over the cobblestones for a maximum of 96 hours. The thin plastic enables the cobblestones to dry without cracking. After this time has passed, wait for 30 days and then apply a concrete sealant to your cobblestones.
