We had a new mirror put up in a bathroom the other day. The handyman who fitted it had a problem with the wall and it cracked within 30 minutes of being put up. He suggested that I purchased a light weight mirror so that it could be attached with special glue made for this purpose (sold in Screwfix).
This is not something that I have come across and just wondered whether anyone had successfully done this? I've looked at a few mirrors on Amazon made to stick on, but they get a lot of negative comments.
