Ceramic tile can be a great option for a counter surface because it is resistant to heat, stains, and moisture. Installing tiles on a kitchen countertop can be an ideal first-time project if you have no experience working with ceramic tiles in the past, because it is a relatively small surface area and also horizontal. The keys to successful tiling are proper planning and making sure the surface is prepared.
Take careful measurements of your countertop several times before finally selecting the tile to use for it. When calculating the number of tiles required to cover it, be sure to allow for specialty tiles, such as backsplash and border tiles. To allow for all the cutting and breaking, you may want to order a little more than you really need. Buying an extra 10 percent is generally a good rule of thumb. Lay the tiles out on the counter once you’ve made your purchase, to make sure you really have enough for the entire job and to see where the cuts need to be made.
You’ll want the countertop tiles to rest on a surface that is solid and able to withstand some moisture. The leading edge of the substrate will need to be strong and thick enough to accommodate the edge you have chosen, while still being completely level in both directions. ¾-inch plywood with a ¼-inch cement backer board is usually the perfect substrate, but there are other options for you as well.
Make sure all cabinets are protected from falling debris or damage. You can cover them with construction paper or plastic sheeting to protect them. It would also be wise to have a cloth on the floor to avoid getting it dirty, which could easily scratch it. If you are installing an undermount sink, this must be done before you attach the backer plate. The backer board itself is easy to cut and install, it can be scored and broken like glass and then attached with special screws that are galvanized.
