When kitchen counter tops become damaged, one often-expensive option is to replace them completely. An option popular with many DIY homeowners is to reface kitchen counter tops with a concrete overlay. Overlays typically require a minimal amount of concrete, making this an inexpensive project.

Use fibre-free concrete for a smooth appearance. Fibre-free concrete is available with pigment added, making it easy to match the colour of the concrete to the kitchen's decor.
Lay dust sheets over the surfaces surrounding your existing counter tops and secure tightly to keep concrete from seeping underneath the cloths.Cover the wall and/or back splash around the top of existing counter tops with painter’s tape.
Cut one piece of wire mesh concrete liner for each flat surface on the counter top with wire snips or sharp scissors. Leave 1/2 to 1 inch of counter top on every side uncovered to prevent the mesh from sticking out if the corners of the counter top chip.
Attach all of the mesh pieces to the existing counter top with 2-inch screws. Sink the screws in straight lines with a drill and screw bit. Space the screws approximately six inches apart.
Combine concrete and water in a plastic bucket according to manufacturer's directions. Mix well with a shovel.
Trowel a 3/8-inch-thick layer of concrete over the existing counter top. Keep the application smooth and even. Remember to cover the edges of the counter top.
Lightly mist rough or uneven areas of concrete with water from a spray bottle. Brush the concrete in these areas with a medium, clean paintbrush to smooth and level the counter tops. Allow the concrete to cure for one hour.
Apply a second layer of concrete to the counter top as thick as you want the finished product to be. Level the concrete as much as possible with the flat side of the trowel. Make the surface of the concrete smooth and even with the spray bottle and paint brush.
Float the surface of the concrete with a rubber float. Place the float very lightly upon the counter top and use broad, rotund motions to work the concrete until you are satisfied with the surface texture. Cure the finished counter top for 48 to 72 hours.
Apply two coats of masonry sealant to the refaced counter tops. Wait two hours between applications. Let the sealant dry 24 hours before using the counter tops. Reapply the sealant annually.
