How to Install 12 X12 Tile on Walls
- 1). Measure from the floor up the wall by 12 1/4 inches and mark it with your pencil. Repeat every 2 feet or so feet along the length of the wall to create a line of pencil marks 12 1/4 inches up. Mark a horizontal line though the marks, using a level.
- 2). Make a vertical line up the middle of the wall, crossing the center of the horizontal line.
- 3). Spread tile mastic along the base of the wall, from the floor up to the horizontal line, using a notched trowel.
- 4). Set the bottom course of tiles into the mastic, starting at the vertical line in the center and working to the sides. The upper edges of the tiles should be aligned with the horizontal line, leaving ¼ inch of space between the bottom of the tiles and the floor. Put tile spacers between the tiles as you hang them.
- 5). Cut the tiles at the ends on a tile cutter as needed to fit along the edges. Hang them with the cut sides facing the walls.
- 6). Spread more mortar across the wall, above the lowest row of tiles. Press the second course of tiles in place, again starting at the middle and building to the sides. Repeat for each, putting spacers between all of them. Do the whole wall.
- 7). Let the mastic set for 12 hours. Pull out the tile spacers.
- 8). Spread grout onto the wall starting at the top and working down. Press the grout into the spaces between the tiles, using the long edge of a grout float. Wipe up the residual grout with a damp sponge.
