Removing Tile Mortar From Walls

Thinset mortar is generally used as the adhesive when tiling a wall.

Removing tile mortar from walls.

Start removing mortar from tile with the tiles free from the wall or floor you can now start cleaning them so can reuse the tile. It depends on a lot of variables in place at the time the tile was set but it comes down to how well the tile is bonded to the mortar. Tiles installed with thinset or another tile adhesive often require more work to remove them. Most likely though if the tiles were installed onto drywall the drywall will be damaged during removal.

Start by holding the tool horizontally or vertically in the case of vertical seams turning on the power and lightly pressing the blade to the grout. Lay the tiles face down and use the putty knife to scrape across the tile back removing as much old mortar as possible. When the old tile falls off or is removed from the wall the thinset that was initially used to attach it has dried and become. Wipe the tiles dry with a rag then scrub them again with the textured side of a kitchen sponge.

Removing tile from older style mortar walls can be very challenging. If any stubborn traces are left you may need to gently chisel it away or sand it off with a rotary sander and 50 grit sanding disk. Fit the oscillating tool with a blade specially intended for removing tile grout. Begin by giving the tile a good cleaning with a sponge and soapy citric acid water as a descaling solution and use a toothbrush to deep clean grout to remove deposits and stains that may make removal more challenging.

Use the scraper to clean off large debris and then clean off any soapy residue with a damp cloth. A wide blade putty knife is helpful in prying the tiles loose. Use a chisel to scrape away the dried thin set carefully chipping it loose from the tile without scratching it or harming the tile itself. There are inexpensive tools designed specifically for grout removal.

In some cases the only way to tear out the ceramic tile is with heavy equipment such as a jackhammer or air chisel. Once those tiles loosen pry them off. Use a ball peen or masonry hammer and cold chisel to tap the pieces free. Use the grout scraper to remove any thin set from the grout lines that is more than 40 of the tile thickness.

Always wear safety glasses when removing ceramic tile. Sometimes you can get a flat chisel behind the tiles and pop them off one at a time almost whole. After removing the grout use a small pry bar or a similar tool to pry the tiles away from the wall. Wipe the tiles down with a dry rag.
