  1. Gather Materials and Tools

    Estimate your tile needs, based on the square footage of the wall area. It’s best to pad the estimate by at least 10 percent to allow for waste and breakage. Home centers and tile specialty shops will stock some tile styles, but specialty styles often require special orders. When required, also buy required trim tiles, such as base tiles, edge trim, or bullnose top trim.

    Most wall tiles are best installed with a mortar-based glue known as thin-set adhesive, made of cement, fine sand, and a water-retaining agent such as cellulose. Thin-set usually has some latex additive that gives it some flexibility to prevent the tile job from cracking.

    Thin-set adhesive is applied with a notched trowel. The proper size of the V-shaped notches in the trowel depends on the size and thickness of the tile and on the recommendations from the tile manufacturer. In our subway tile sample project, the recommendation is for a trowel with 3/16 x 5/32-inch notches. This size works well for most tiles that are 6 x 6 inches or smaller.

  2. Protect Surfaces

    Tiling can be a little messy, so it’s wise to protect floors, countertop surfaces, and fixtures against spills from tile adhesive and grout.

    Buy a thick rosin builder’s paper, which you can find at a big-box home improvement or painting supplies store. Cover the countertop and floor surfaces with the paper and secure it in place with painter’s tape. Cut slits in the paper where sink faucets and other fixtures are located. Cover the exposed surfaces of the fixtures with strips of painter’s tape.

  3. Plan the Layout

    The goal in planning the layout is to make sure that there won’t be thin slices of cut tiles at the sides or at the top and bottom. Spend time getting the layout right; you will use the layout lines to install the tiles beginning at the center and working outward in quadrants.

    Start by choosing the most visible wall in the room. (In a bathroom, this is often the center of the vanity wall above the sink). Use a tape measure to establish the horizontal and vertical center point on the wall.

    From this center point. use a level to extend vertical and horizontal layout lines from side to side and from ceiling to floor. Then, use a sample tile to mark the layout lines to show the approximate location of each tile along the lines, including the thickness of the grout lines.

    If you begin to see that there are too many areas requiring thin slices of tile, you can adjust the starting point left or right, up or down, to create the most effective layout.

  4. Apply Thin-Set Adhesive

    Once you are satisfied with the layout of the vertical and horizontal lines, begin applying adhesive, starting at the center point and working on one quadrant at a time.

    Spread adhesive onto the wall quadrant using the flat side of the trowel, covering only as much of the wall as you can comfortably work in 20 to 30 minutes.

    Immediately trowel back over the skim coat, using the notched side of the trowel to create a pattern of ridges and valleys in the wet adhesive. Hold the trowel at a 45-degree angle and “comb” the adhesive in one direction.

    The wall section should be covered with thin-set adhesive, but you should be able to see the wall surface between the ridges of adhesive left by the notched trowel.

  5. Lay the First Row of Tile

    Position the first tile (or tile sheet, if you are using mosaic tiles) into place on the wall at the center point of the layout. Align it carefully with the horizontal and vertical layout lines. Press the tile firmly into the adhesive; as you press, the adhesive flattens out, filling the spaces between the ridges created by the trowel.

    After the first tile or sheet is set in place, complete the first row along the horizontal layout line, using plastic spacers to ensure uniform spacing between tiles. Install only the full- tiles—leave the trimming of partial tiles until the end.

    When the first row is complete, check it for level using a carpenter’s level, then begin the second row of tiles, taking care to offset the vertical grout joints by exactly one-half the tile . Continue installing the subsequent rows, again using plastic spacers to maintain uniform joints between tiles. With the running-bond pattern we are using, it is critical that you get the offset correct so that the joints have the proper spacing from row to row.

  6. Complete the Field Tile Installation


    After each small section of wall is completed, use a short block of wood and rubber mallet to very lightly rap over the surface of the tiles. This action will “set” the tiles in the adhesive and flatten the surface. 

    Working systematically in sections, repeat this process until the entire wall is covered. Leave the tiles that need to be trimmed or cut until the end of the project. As you reach the last full tiles, scrape off any excess adhesive from the areas of the wall left exposed. This will prevent the adhesive from hardening as you trim the last tiles and prepare to finish the installation. 

    As the adhesive hardens, inspect the grout lines and make sure they are free of excess adhesive. If necessary, scrape away the excess using a pointed stick or small screwdriver. The grout lines need to be clear and open for grout to adhere when you reach the finishing stage. 

    Use a damp sponge or cloth to wipe any adhesive from the face of the tile. The adhesive is very simple to clean when wet, but will be very difficult once it dries.

  7. Fill the Side Gaps

    After the full-sized field tiles are all installed, cut and install the partial tiles along the sides of the wall. Cutting partial tiles can be done with a manual snap cutter or a wet saw.

    When using a snap tile cutter, place the tile into position in the tile cutter, then score the surface by firmly moving a tungsten carbide scoring wheel from bottom to top across the face of the tile surface. Then, place the pressure bar pad across the tile and apply firm pressure on the lever to snap the tile across its scoreline.

    If you have many tiles to cut, a tile wet saw is the better option for cutting partial tiles. It’s also essential for thicker floor tiles, or for porcelain or natural stone tiles, which are very difficult to cut with a snap cutter.

  8. Fill Remaining Gaps

    Where tiles need to be trimmed to fit around outlets, light switches, pipes, and other obstacles, use a tile cutter or tile nipper to trim them to fit the space. If filling in around outlets, make sure the tile doesn’t cover over the opening of the electrical box. Make sure to wear eye protection before trimming or cutting tile.

    When installing small tile pieces, it’s easier to butter the back of the tiles with adhesive. Then, score the adhesive with the notched side of the tile, and press the cut tile into place on the wall, using plastic spacers to maintain uniform grout lines.

  9. Install Trim Pieces

    If your layout includes border tiles or other trim pieces, install them last. Here, we are using 1 x 6-inch cap tiles. Installation is similar to how the field tiles were installed: Butter the backs of the tiles, then press them into place on the wall.

  10. Inspect Grout Joints

    Make a final inspection of all grout lines. Clean out any excess adhesive between grout lines. Let the tile adhesive dry for 24 to 72 hours before grouting the tile.

    Tip

    Some people like to pry out the plastic spacers before grouting, but it’s best to follow the grout manufacturer’s recommendation on this. It’s generally not necessary if the spacers have been pushed fully into the joints; you can simply apply grout over the tops of the spacers.

    If you do want to remove the spacers, make sure to do it before the thin-set adhesive has fully dried.

  11. Grout the Tile

    Using the tile manufacturer’s instructions, apply grout to the joints. Joints that are wider than 1/8-inch typically call for a sanded grout, while narrower joints use non-sanded grout. Make sure to clean the excess grout off the tiles and to wipe away the dried haze after the grout dries.

    After the grout fully hardens and cures (this can take from a few hours to a couple of days, depending on the grout), apply a sealer if the grout manufacturer recommends it.
