Four days ago I layed porcelain tile on drywall using thinset mortar. When I went to remove the shims which were holding the tiles in place, chunks of the tile chipped off at the bottom on one of the tiles. Unfortunately, this will show and won't be covered by anything! Can I try to remove that single tile or will the drywall just be destroyed? I'm just sick about leaving something like that. It will make a brand new job look bad.
