good morning all, I’ve got a customer who’s had a shower installed in their bathroom when there was only a bath before. The plumber has chased the pipe work for the shower into the walls. It’s an old property and the walls aren’t the best! My question is can you still use a waterproofing kit on plastered walls?? I’ve never faced this before so any advice on any aspect of the installation would be appreciated, regards, Stu.
