A concrete overlay is an inexpensive do-it-yourself project. The finish can be left plain and smooth, or be stamped and stained for a custom result to suit any design plan.
Things You Will Need
-
Roughen the existing tile surface with 60-grit sandpaper on an orbital sander. Move the sander back and forth across the tiles evenly. Wipe away all of the dust after sanding.
-
Apply a smooth, thin layer of concrete bonding adhesive to the tiles. Use a paintbrush to spread the adhesive over the entire counter area.
-
Cut woven wire mesh with wire cutters or tin snips to fit the edges of the counter. Woven wire mesh is sold anywhere where concrete mix is available. Use a staple gun to attach the mesh along the edges of the counter. This gives the concrete something to hold onto on the sides.
-
Mix general use or type I concrete according to the manufacturer's directions. Mix it in a medium-size bucket so the concrete can be moved with you as you work down the countertop.
-
Protect your hands with rubber gloves and then begin applying the concrete to the counter by hand. Smooth the concrete between the cracks of the existing tile. Apply only a thin layer at first, just enough to fill in between the tiles. Spread slowly along the edges to cover the mesh. Allow the first layer to dry for several hours.
-
Apply a second layer of concrete by hand-spreading a thick layer over the entire surface of the counters. Use a trowel to square off the edges and smooth the top. Allow to dry for 12 hours before applying and smoothing out a third and final layer.
-
Add a smooth finish with an epoxy concrete sealant. Roll on the sealant with a paint roller and allow to dry. Ventilate the area well during this process.
