Right then, I’m changing my bathroom and after removing the old tiles I have patches (not very deep, adhesive would more than cope filling it) down to the old black mortar/render they used to level the walls. Now it seems a bit dusty and was wondering would a coat of BAL be advisable or should I do something else?
Due to width of bathroom I’m not going to be able to skim a new surface so I just need to confirm the best way to prepare the old wall.
Thanks for any tips in advance
