A ceramic tile countertop is decorative and useful, providing a solid, moisture-resistant surface. Laying a tile countertop generally entails at least three kinds of tiles: field tiles, the regular squares that make up most of the surface; bullnose tiles, which are just like field tiles but are rounded off on one side to give a clean finish to the front row of tiles; and trim tiles, which are narrow pieces for the front edge. Using self-spacing tiles (with nubs on the sides to set them a little apart from each other) will make the project easier.

1. Step 1

   Sand the wood surface of the countertop base with your vibrating sander and 100-grit sandpaper, getting it smooth and flat. Clean up the dust.

2. Step 2

   Use your tape measure and square to mark a line across the center of the countertop, from front to back. Lay one side of the square along the front edge of the countertop to ensure the line is exactly 90 degrees in relation to the front. Take the line down around the front edge as well.

3. Step 3

   Spread tile adhesive on the front edge of the countertop, using your notched trowel. Press the narrow trim tiles along the front, starting on either side of the center line and working your way toward the edges. Cut the end pieces as necessary on your tile cutter.

4. Step 4

   Spread adhesive on the top of the countertop, along the front. Press your bullnose tiles into place, with the bullnose side of the tiles facing forward and lining up with the face of the narrow tiles on the front edge. Build out toward the edges and cut the end tiles as necessary.

5. Step 5

   Lay the rest of the tiles starting at the center line and working out toward the edges. Cut the end tiles. Let the tiles set overnight.

6. Step 6

   Spread grout over the surface of the tiles with a grout float (a flat rubber trowel), pressing the grout into the lines between the tiles and squeezing it off the face. Wipe off the excess grout with a damp sponge. Allow the grout to dry for the time recommended by the manufacturer.
