Create the Mold

Measure the base upon which the countertop is to be installed. Then using these measurements, cut the required strips out of a melamine or a wooden board to make the mold. Be careful to take a few centimeters more than the exact measurements to give room for finishing later on. After you have cut all the sides, attach them together using nails or screws to create a tight fit. The corners should be tightly fitting so that the wet concrete doesn’t come out.

Prepare the bottom board

The bottom part of the mold will be the top facing part of your countertop, so it is very important to make that surface extremely smooth. Cut the dimensions for sink and faucet from the bottom board to create space for installations. Then, run a silicone bead in all the inside corners and seams and smoothen them using your fingers. The silicone will seal the joints of the mold and prevent the wet concrete from coming out. Once the silicone dries up, carefully clean the mold to remove any sawdust or other debri. Now your mold is ready.

A sturdy internal frame made with steel rebars will hold the concrete in place and prevent it from breaking away. Measure and cut steel rebars using a cutter to fit the mold. Then lay them in a criss cross pattern on top of one another and tie them up using metal wires. This will prevent your countertop from cracking off. Then place small stones on the base and rest this rebar frame on top of them. Now your mold is ready for the concrete pouring.

Prepare the concrete mixture and pour it

Prepare a mixture of sand, loose gravel, cement and water to get concrete. Keep the proportions of sand: gravel: cement in the ratio 3:4:3 and mix enough water to prepare a thick concrete mixture. If you want to add color to your countertop, then you can also add color pigments to the mixture. After the mixture is ready, pour it out in the mold while constantly shaking it to remove any air bubbles. Smoothen the top part with a trowel and cover it up with a plastic sheet and allow it to dry overnight. Once dried, keep on pouring water on top of it every 5-6 hours for 2 days to strengthen it.

Remove the Mold and Finish the Slab

Remove the screws and pry out the sides of the mold. Then take out the concrete mold with the help of a small pulley crane as it will be very heavy. You may also call for some manual help. Turn the concrete slab over and grind the top face, sides and edges using a 220 grit sandpaper to give a smooth and curvy finish. You can paint the countertop or apply a coat of epoxy coating on top.
