Tips for Removing Ceramic Tile

 Success at removing ceramic tiles from floors depends on the material the tile was fastened to at installation. In a very old house, the tiles might have been glued directly to a cement subfloor, making removal very difficult. In a newer property (built within the last 40 years), the ceramic tiles were probably fastened to a lightweight cement backer board, nailed to the timber subfloor. Follow these steps for effective removal of ceramic tiles attached to cement board.

What You'll Need:

• 75mm (3-inch) stiff-bladed scraper or filling knife

• Small flat-headed hammer

• Flat garden spade

• Steel crowbar

• Portable angle grinder

• Wet/dry vacuum cleaner

• Wraparound safety goggles

• Heavy leather gloves

• Long-sleeved shirt or jacket

• Half-face dust mask

Step 1: Start at the Edge of the Floor

Prepare to remove tiles from a floor edge that adjoins carpet, vinyl tiles, or other surfaces. Place the scraper under the edge of a tile, and tap it with the small hammer to lift off a tile. Depending on the strength of the tile adhesive, the cement board may come free along with the tiles.

Step 2: Remove the Tile Grout

Pry between the tiles with the scraper to pulverise the grout, so you can more easily pop the tile from the backing board. If the grout is very hard, use the angle grinder to grind out the grout and release the tile more easily.

Step 3: Continue to Remove Single Tiles

Once you have removed the tile grout and a few tiles, slip the scraper under each tile with the handle as close to the floor as possible. Tap the knife handle sharply with the hammer. The tile may break up or lift off all in one piece. Continue to remove tiles until a section of cement board about 20 cm by 15 cm is exposed. Avoid striking ceramic or porcelain tiles with the hammer, as they will shear into razor-sharp flaked pieces.

Step 4: Remove the Cement Board with Tiles Attached

Once you have cleared tiles off an area of cement board, break it up with the hammer so you can see the floor joists. Insert the flat garden spade under the cement board and use it as a lever to remove larger areas of the board with the tiles attached. Stop from time to time and vacuum the area with a wet/dry vacuum cleaner to avoid inhaling cement and tile dust. Move the spade to the left or right side of the floor joist as you encounter the nails used to attach the cement board. The bigger the gap you can create between the cement board and the floor joists, the larger the area of tile you can remove at once.  

Step 5: Remove the Nails from the Cement Board

Use a claw hammer or a steel crowbar with a nail slot to pull the nails out of the cement board. You can then remove these fragments from the floor joists and dispose of them.  

Step 6: If the Cement Board was Screwed Down

Use a power drill with a screwdriver bit to back the screws out of the cement board pieces, then remove and discard them. Vacuum the room thoroughly to remove dust from all surfaces.

Removing Ceramic Tile

 Depending on where they are and how they're installed, removing ceramic tiles can be either a nightmare or a relatively simple job requiring little effort. Stripping all the ceramic tiles from a wall or floor, rather than just trying to remove one or a small number, will also be easier simply because you're not worrying about damaging the surrounding tiles. Here are a number of different situations in which you’ll be removing ceramic tile and some ideas on how to do it right.

What You'll Need:

• Putty knife
• Hammer
• Chisel
• Flat-blade shovel
• Safety glasses
• Gloves
• Dust mask

Ceramic Wall Tiles on Cement Board or Gyproc

This is by far the easiest situation. If you want to protect the underlying wall, take a three-inch, stiff putty knife and hold it at a very low angle relative to the wall. Starting at the edge of the wall, place the blade against the mastic and give the handle a solid tap with a hammer. In most cases the knife will slide under the tile and by simply lifting the handle up, the tile will pop off the wall.

Removing a single tile from a wall can be trickier. In this case, your first step is to remove the grout surrounding the tile using a rotary tool, a thin chisel, or a grout removing tool. Once you've taken care of the grout, use your stiff putty knife again, tapping the end to slide it under the tile.

Removing Tiles on Concrete Board

Removing floor tiles laid on cement board is more work than wall tiles but the methodology is similar. Choose an edge, where flooring and the wall come together, and start by removing any edgings or moldings. Now, you may be able to remove a starter tile using your putty knife, but more likely, you will need to remove the grout around a few tiles first.

Once you get a few starter tiles off the floor, break up the underlying cement board by banging on it with your hammer and discard it. Now you've created a small opening where you can slide a flat-bladed shovel under both the cement board and the ceramic tiles. Lifting up the shovel from underneath will break the cement board and the grout holding the tile so you can remove it. Repeat the process, sliding the shovel under the cement board then lifting and you can get rid of the floor in chunks.

Old Ceramic Tiles Laid Directly onto a Cement Base

This is by far the most difficult situation to deal with and thankfully this installation technique isn't used anymore. There are lots of old homes with ceramic tiles installed right onto a cement base. Once the mortar has cured, the concrete base and the floor tiles are in reality a single piece. There are only a few ways to remove ceramic tiles in this situation. One solution is to break up the tiles with a sledge hammer. However, it's a back-breaking, labor intensive project, and you risk damaging the base if you’re not careful.

The easier solution to this problem is to use a chisel and a hammer. You will want to start at a broken tile, if you have one, or in an area with loose grout so you can get the chisel under the tile. As you get the chisel tip underneath, tap the end of the tool with your hammer to work it further in. These tools will also work to chip away at the old thinset mortar adhered to the floor, which can’t be removed with a sledgehammer. It will be a time-consuming job, but one that will get you a good, clean subfloor to proceed from.

A Safety Reminder

No matter whether you're removing a whole floor or wall of tiles or just a single tile, remember you need to wear wrap-around eye protection, good quality work gloves, and a dust mask. Obviously, it's also a good idea to place protective covering on the floors and walls around where you're working.
