How to De-Form, Polish and Install a Customized Concrete Vanity Top
DIY pros show how to finish a concrete countertop for a bathroom vanity, including de-forming, polishing and installation.
Measure the current countertop that will be replaced or the vanity edge that the counter will rest on and cut the bamboo sheet to those dimensions.
Cut an additional strip of wood for the outside edge of the three sides. This will add thickness and create a clean edge on the countertop.
Use wood glue to adhere the strips to the bottom edge of the bamboo sheet.
Use a nail gun and brad nails to secure the edge. Shoot in two nails right next to each other at 6" intervals along the underside.
Sand all sides of the countertop with an orbital sander. Wipe the countertop with a cloth to remove dust.
Apply three coats of epoxy topcoat, sanding lightly in between each coat.
Measure the size of the sink and faucet holes and tape the area to be cut to avoid scratching the finish of the bamboo.
Draw a pencil line on the tape and use a rotary saw to cut out the sink hole. Use a drill to cut the faucet hole.
Apply a small bead of caulk to the vanity edge where the counter will rest.
Lay the countertop down, make sure it is centered and apply firm pressure to the edges.
