Steps

Preparing a Shower Wall for Tile with Concrete Board:
  1. Begin by removing any existing tile and drywall by chipping out the grout with your chisel and hammer set. Then begin pulling off the tiles by forcing the teeth of the hammer behind the drywall and pull the boards down. It is recommended to have your water shut off to the shower and protect any fixed surfaces, such as the tub and existing floor tiles.
  2. With any high moisture application, it's in your best interested to replace the original drywall boards. In this case, use 1/2" concrete board or water resistant drywall board with the appropriate screws. The screws should be placed every 8 inches into the studs.
  3. Make sure the surface is level and all exposed screws/seams are patched with a paintable waterproofing or Kerdi band. The Kerdi band is applied with a thin coat of unmodified grey mortar and a 3/16" V-Notch trowel. Let the waterproofing dry and clean the surface of any dirt

Preparing a Shower Wall for Tile with Kerdi Board:
  1. Begin by removing any existing tile and drywall by chipping out the grout with your chisel and hammer set. Then begin pulling off the tiles by forcing the teeth of the hammer behind the drywall and pull the boards down. It is recommended to have your water shut off to the shower and protect any fixed surfaces, such as the tub and existing floor tiles.
  2. With any high moisture application, it's in your best interested to replace the original drywall boards. In this case, use 1/2" Kerdi board with Kerdi board washers and Kerdi tape for the seams. The screws should be placed every 8 inches into the studs.
  3. Make sure the surface is level and all exposed screws/seams are patched Kerdi band, including the washers. The Kerdi band is applied with a thin coat of unmodified grey mortar and a 3/16" V-Notch trowel. Let the waterproofing dry and clean the surface of any dirt.

Preparing a Shower Wall for Tile with Kerdi Membrane:
  1. Begin by removing any existing tile and drywall by chipping out the grout with your chisel and hammer set. Then begin pulling off the tiles by forcing the teeth of the hammer behind the drywall and pull the boards down. It is recommended to have your water shut off to the shower and protect any fixed surfaces, such as the tub and existing floor tiles.
  2. With any high moisture application, it's in your best interested to replace the original drywall boards. In this case, use 1/2" concrete board with the appropriate screws and Kerdi membrane. The screws should be placed every 8 inches into the studs.
  3. Make sure the surface is level and clear of dirt. Begin to mix the appropriate mortar for your installation in your mixing bucket according to the manufacturers' instructions. It is advised to ware a dust mask, goggles and gloves when working with mortar as it is caustic. With Kerdi, you are required to use unmodified grey mortar with a 3/16" V-Notch trowel. Apply the mortar along one section of the surface covering the diameter of the Kerdi membrane, about one metre, pulling the trowel at a 45 degree angle. Cross over the mortar 2-3 times to eliminate air bubbles. Apply the sheet(s) of Kerdi membrane beginning from the top of the wall and smoothing it out with a grout sponge along the way. Repeat this process throughout the shower and let the waterproofing dry for 12-24 hours.

Tiling Shower Walls:
  1. Begin to mix the appropriate mortar for your installation in your mixing bucket according to the manufacturers' instructions. It is advised to ware a dust mask, goggles and gloves when working with mortar as it is caustic. When applying tile over concrete board, you are to use pre mixed wall glue for light weight tiles, such as ceramic, and polymer modified mortar for stone or heavy set tiles. Over Kerdi Membrane or Board, you are to use unmodified mortar regardless of the type of tile. In both cases, use white adhesive for stone and grey for porcelain or ceramic. Use the notched trowel, generally a 1/2" or 3/8" square notch for larger tiles and 3/16" V-Notch for mosaics, and spread the adhesive on a 2-3 square foot surface at a time. Hold the trowel at a 45 degree angle with the teeth of the trowel touching the surface. Simply drag the adhesive across and be sure to cross back over your previous application to smooth out any air bubbles.
  2. Apply a small amount of adhesive to the back of the tiles using the same technique as on the walls, but with half the amount of product. Lay the tile(s) on the surface into the adhesive and apply pressure to create a bond. Apply your next tile in the same fashion with spacers in between the tiles. Remove any excess mortar from the tile face and grout joins as you go and check to ensure each tile is level. Repeat this process across the shower walls. When you approach cuts, it is best to cut them as you complete each row and keep the excess for the opposing wall.
  3. To create cuts, measure the surface and create a mark on the tile you intend on cutting. Use your tile cutter, preferably a wet saw, to cut along the marked line. It is advised to wear goggles when cutting any tile.
  4. Once the surface is dry, begin applying the grout. Mix the grout according to the instructions, or until it has reached a peanut butter consistency, in your mixing bucket. Apply to the dry tile surface using the grout float in a cross sweeping pattern, held at a 45 degree. The grout should be pushed over the tile joints in 2-3 directions to ensure they are appropriately filled in.
  5. Begin removing the excess grout 5-10 minutes after application. You'll be aware of the appropriate time because the grout will begin to show a white haze. Fill a clean bucket with water and use your grout sponge remove the grout by washing the floor. Be sure not to use too much water or wash in a spiral motion. For the best effect, pull the grout downward in a dragging motion. This may have to be repeated once or twice with glossy or textured tiles.
  6. Use a clean, dry cloth to buff the entire surface clean of any dry particles.
  7. Seal any necessary surfaces, such as grout or natural stone tiles, 3-5 days after applying the grout.
  8. Install any fixed elements, such as the shower head and mixing valve, over the newly installed tile. Put a thin bead of bathroom silicone along the base of the tiles and in the corners of the walls.

Tips

It is recommended to ware safety goggles and gloves while removing tiles and wallboard.
Always double check your measurements before creating any cuts into the concrete board.
