  • Wood screws
  • Screwdriver
  • Silicone caulking
  • Foam boards
  • Utility knife
  • 3/16-inch reinforcing mesh
  • Wire cutters

  • Electric sander/polisher
  • Diamond grinding pads, 50- to 3,000-grit
  • Concrete sealant

Step 1

Purchase a countertop mold. Put the mold together by screwing the sides and bottom portions together using wooden screws. You should seal the seams with silicone.

Step 2

Place the foam inserts on the botton of the mold. Cut the foam with the utility knife to indicate the location, size and shape of the holes that may be in the countertops. Verify that the inserts are the hieght of the countertop. Cut the reinforcing wire the size you need. Add an extra ½ inch to the countertop edges. Set the mesh aside for later use.

Step 3

Mix your concrete. Do this according to the makers instructions. You a mixer attachment for an electric grill.

Step 4

Pour you concrete mix into the mold. Fill it only halfway. Make sure the mixture spreads evenly using the trowel. Make sure to fill the corners as well. Tap the side of the mold to help the concrete settle in place and to remove air. Allow the mix to stand for 10 minutes.

Step 5

Place the reinforcing mesh on the concrete. Pour the remaining concrete. Tap the sides to remove air. Use a piece of wood to even out the concrete. Allow the concrete to stand for a week.

Step 6

Make sure to smooth out the sides and the surface of the countertop. Throughly inspect that each run is polishing the countertop. You need to change grits to finely polishly the surface to a gloss and shine state.

Step 8

Use a concrete sealant to seal the surface from water or staining. Apply the sealant with a brush and allow it to dry overnight before mounting.
