How to tile mosaic backsplash

Tiling a backsplash above the counter is one of the easiest ways to upgrade an old, tired kitchen on a tight budget. You can choose from the vast array of handsome ceramic tiles available, including the easy-to-install one we show here—mosaic tiles.

In this article, we'll show you how to install the tile sheets. You'll need basic tile tools, available at home centers and tile stores, including a 3/16-in. trowel and a grout float. You'll also need mastic adhesive, premium grout and grout sealer. You can rent a wet saw to cut the tiles.

Before installing the tile, clean up any grease splatters on the walls. Wipe the stains with a sponge dipped in a mixture of water and mild dish-washing liquid. If you have a lot of stains or they won't come off, wipe on a paint deglosser with a lint-free cloth or abrasive pad so the mastic will adhere. Deglosser is available at paint centers and home centers.

Spread a thin layer of mastic adhesive on the wall, starting at the center line. Spread just enough adhesive for two or three sheets at a time so the adhesive doesn't dry before you set the tile.

Cut tile sheets to the nearest full row to fit around outlets, then fill the gaps with tiles cut on a wet saw. If you're lucky, you can fit the tile sheets under upper cabinets and around outlets by cutting the mesh backing with a utility knife. If not, you'll have to cut the tile with a wet saw.

Force grout into the joints with a float. Scrape off excess grout by moving the float diagonally across the tile.

Wait 24 hours after installing the tile to add the grout. We used a premium grout that has a consistent color and resists stains better than standard grout. Since the backsplash will be subject to splatters and stains from cooking and food prep, we recommend spending the extra money for a premium grout. You can find or special order it at home centers or tile stores. One brand is Prism. Sanded grout will also work and will save you a few bucks.

Mix the grout with water until it reaches mashed potato consistency, then put some on the wall with a grout float. Work the grout into the joints by moving the float diagonally over the tiles. Hold the grout float at a 45-degree angle to the tile. Scrape off excess grout with the float after the joints are filled.

Ten minutes after grouting, wipe the grout off the surface of the tiles with a damp sponge. If the grout pulls out of the joints, wait another 10 minutes for it to harden. Continually rinse the sponge in a bucket of water and wipe the tiles until they're clean.
