Replacing a mirror tile. I was installed using mirror mastic.
Tile is in a very tight area. Should you tape it and just crack the mirror?
But how about the removal of the mastic

The mystic can be either scraped or sanded to get enough off to install new tile.

The mastic takes many years to harder, you should be able to chip it off with a sharp putty knife, and yes tape it for safety

Very good. Thanks
