Build the mold

Use melamine-coated particleboard

Place a sheet of 3/4-inch melamine fiberboard that’s larger than your finished dimensions on two sawhorses. The cement you’ll be using is heavy, so use a few 2- x 6-inch boards stretched between the sawhorses as additional support for larger countertops. Mark the size of your countertop on the panel. Use a table saw to tear 1-1/2-inch wide strips (or the thickness of your countertop) of the melamine for the edges of the mold. Measure and crosscut the strips to length.

The strips used for 2 sides of the mold are going to be used as an abutment to the opposite edges, in order that they should be cut 1-1/2-inches longer than the countertop dimensions to accommodate for the thickness of the melamine board. Clamp the pieces in situ on top of the bottom panel, drill pilot holes in 12-inch intervals, and use coarse-thread screws to secure the shape. Apply a bead of silicone caulk inside the mold at each corner joint and round the perimeter. Run a wet finger along the silicone to smooth it, pressing it into the joint and creating a rounded edge.

Use a dark color of caulk to form it easier to ascertain the surplus that you’ll remove later. If your countertop requires a cutout for a sink, cut a bit of 1-1/12-inch foam insulation panel to the size of the opening you would like. Glue the froth to the bottom of the countertop form within the proper location. Use painter’s tape around the edges of the froth to stop the concrete mix from seeping in.

Cure the concrete

Cover with plastic sheeting and let dry for at least 18 hours

Next, use a wood float, raising its vanguard slightly, to smooth the concrete further. Meanwhile, tap the edges of the shape gently with a rubber mallet (or grab a partner and shake the shape side to side very lightly) so on create the vibrations necessary to dissipate air bubbles. After letting the concrete harden for a few of hours, come to the shape and another time run a tool over the concrete surface. This time, reach for the trowel and use it to eliminate any lingering imperfections.


Remove the slab from the mold

Take apart the mold, and pull it away from the edges

The Conclusion
