How Do You Tile Uneven Walls?

To tile an uneven wall, mark the center, dry-fit the tiles, cut them, mount them with mortar, and apply grout. This three-day process requires a measuring tape, a chalk line, chalk, tiles, a saw, mortar, a trowel, grout, spacers, wedges, a mallet, a grout float, and a grout sponge.

  1. Mark the center of the wall

    Measure the height and width of the wall. Snap a chalk line along the vertical mid-point of the wall.

  2. Dry-fit the tiles

    Draw a chalk outline of the wall on a hard floor or driveway. Arrange the tiles in the outline. Notice where the tiles need to be cut in order to fit.

  3. Cut the tiles

    Use a wet saw to cut the tiles, return them to the chalk outline, and verify that all of the tiles fit inside it.

  4. Mount the tiles with mortar

    Load a trowel with mortar, and spread it along the bottom of the wall. Smooth the mortar until its surface appears even. Press a row of tiles into the mortar, starting at the center. Lay several rows of tiles, and tap them with a mallet to create a level surface. Place spacers between the tiles, and push the tiles together with wedges. Use this technique to tile the rest of the wall. Let the mortar dry for 24 hours.

  5. Apply grout

    On the following day, remove the wedges and the protruding portions of the spacers. Squeeze grout between the tiles, and press it down with a grout float. Make sure that the spacers are obscured. Scrape away the excess grout, wait 10 minutes, and buff the wall with a wet grout sponge. Rinse and re-wet the sponge frequently, and rub the wall until the tiles are clean. Leave the wall undisturbed for 24 hours.
