Remove tile
When the tile is arched, it can be taken down directly in most cases, because when the tile is arched, the tile and cement have been layered. If you can't take it off, you can use a flat metal ruler to lift it slowly along the ground and take it off.
Clean tiles
After that, the cement originally stuck on the edge and back of the tile will be removed, cleaned with a rag, and then coated with white glue on the back of the tile and compacted in situ.
Find a decorator.
If there are a lot of floor tiles arching, it is recommended to find a decorator to repaint them, because this shows that there was a problem when the tiles were laid at the beginning, and repaving can completely solve the problem, otherwise the symptoms will not be cured.
Marking order and direction
Mark the order and direction of removing floor tiles. This can restore the original appearance and save some material costs.
