In my bathroom I’m going to be ripping out the green plasterboards in the wet area and putting in the fibre insulated backer boards and tanking it. But the other sides of the bathroom where it’s not exposed to much water or moisture is currently painted but is also green plasterboard. I want to tile the entire bathroom. What’s the best way to tile over the existing boards that have paint? I’m assuming the paint really should be stripped off first? But what’s the best way to strip the paint without damaging the surface of the boards so that I can tile over it?
Thank you.
Thank you.
