Hi there,
I am having my bathroom done up, and I need to re-tile the walls.
The old tiles have been removed (I couldn't tile over them as I wanted to extend the area of tiled wall), but there are still thick traces of the adhesive on the wall in some areas. Do I sand this down first before starting to tile? Or do I just put the new adhesive straight on top and start tiling?
Any help would be greatly appreciated!
