Hi all. I will be glueing a bathroom mirror to the wash basin wall soon. However, I removed some tiles a couple of weeks ago and it wasn't very difficult. It seems the tile cement had afixed itself to the emulsion paint only, and merely required a bit of encouragement with a thin screwdriver and 3 @ 20cm x 25cm tiles came off undamaged.
This is a lath & plaster wall but I'm not very keen on the idea of knocking holes in it to insert noggins to match up with the miror drill holes. So should I treat this emulsion with something before No-more-nailsing the mirror to it?
Thanks.
Arthur
