Steps To Make The Countertops By Yourself
Build the mold

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.
Mix the concrete

When you’re able to mix concrete for the project, closely follow the manufacturer’s instructions. Aim to realize a thick, oatmeal-like consistency. If you discover that it’s too hard to figure with, add a touch of water (but only a little). The wetter the concrete, the more brittle it becomes upon drying. Consider augmenting the concrete countertop mix with additives that inhibit cracking and shrinking. referred to as admixtures, these need to be readily available at your local home improvement mercantile establishment.
Pour the concrete

Pour enough concrete into the shape to fill its volume completely, then use your hands to figure the fabric along the sides and into the corners. If you attached the steel mesh reinforcement to the frame itself, cut those connections now. Then proceed to use a flat board, like a one-by-four, to level, or screed, the concrete. Move the board back and forth so as to smooth the surface and fill low spots. Keep a trowel at the ready, so you’ll quickly affect any excess.
Cure the concrete

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

Remove the screws that were holding the shape together. Insert a spatula into the side joints with gentle taps of a hammer. Carefully pry the shape sides from the concrete. Use the spatula and shims along the perimeter of the kitchen concrete countertop to loosen it from the fiberboard base. Lift the slab and take away the bottom melamine panel. Turn your new countertop over and rest it confront on the sawhorses
Finish the surface

Sand the concrete countertop surface and sides to show any air bubbles near the surface using an orbital sander and 80-grit sandpaper. Mix a slurry and include an equivalent pigment ratio if your concrete is tinted. placed on some rubber gloves and spread it over the whole surface to fill and gloss over any voids. Allow drying.
Apply a sealer

Sand the whole slab again using the orbital sander and 80-grit abrasive. Wipe clean and switch to 120-grit. A final sanding using 220-grit abrasion will leave a smooth polished surface. Vacuum the concrete countertop then wipe with wet cloths to get rid of all dust. Allow drying. Concrete is porous and may easily stain, so it’s vital to use a concrete sealer to assist prevent permanent blemishes. Choose a food-safe variety if your countertop is going to be utilized in the kitchen. Apply the concrete countertop sealer consistent with package instructions. generally, this may require multiple coats and maybe a required step to guard your new DIY concrete countertop.

Final Verdict
The Conclusion
This is an excellent way by which the concrete forms are built and therefore the countertop is poured, complete with whatever sink cutouts, coloration, or additives are requested. During fabrication, the countertop slabs are usually reinforced with fiber or metal mesh of some type to offer them strength and rigidity. After fabrication, the concrete countertop is allowed to cure fully, and therefore the surface could also be ground and polished to whatever finish the client has requested. Sealer is applied, often a really hard epoxy. Once curing and finishing are complete, an installation crew carefully delivers the countertop to the worksite and installs it.
