Hi all, I'm brad new to this site and am a novice at Plaster boarding. My question is: I want to plaster board 2 outside walls in my bedroom, my idea was to buy some plaster board and some polystyrene sheets to affix to the plaster board and then I was going to fix them to my wall over the existing plaster (which isn't in great shape). I was then going to just paint directly onto the boards when they've been applied to the wall. I just need to know whether this will work and what types of tools adhesives I'd need to do it.
Many thanks in advance!!
