GGCL Guide: How to remove ceramic wall tiles from plaster walls
It is an extremely difficult process to remove the ceramic wall tiles installed on the plaster board. If the installation was done in the contemporary method then the task becomes a bit simpler with thin layer of mortar or adhesive used under the tiles to stick it to the plaster board. In case the installation was done in the conventional manner then the task becomes quite daunting. You would find a thick wall of mortar under the tiles along with a metal mesh held against the plaster board. While the procedure to remove the ceramic tiles from the plaster walls is similar in both the cases, but it becomes physically exhaustive if the installation was done in the conventional method.
Before starting to remove the ceramic tiles from the plaster board, spread drop cloth or cushioning material under the area you are going to remove the tiles from. This cloth would help you avoid damaging the floor. Use the utility knife to remove the caulk from the tile edges. Now use the grout removal tool to scrape out the grout from the joints. Make sure you use the tip of the grout removal tool for scraping for efficient and clean removal of grout. In case the grout is too hard, use hammer to tap on the grout removal tool to break the grout.
Find the exposed edges of the tiles. Any tile which has the maximum exposed edge is where you should start. Insert the tip of metal chisel in the exposed edge diagonally. Hammer the other hand of chisel gently to push the chisel deeper along the edge. This would remove the tiles off the wall. Once all the tiles have been removed, use the chisel or the scraper to scrape off all the remaining adhesive or mortar from the plaster board.
