We want to have a flat surface for DIY installation of tiles in our bathroom. The tiles will go up about 2m in some areas, and 1m in others, with the untiled bits of wall painted plasterboard.
I have searched the posts and think that the best option for us would be to fix Villaboard to the uneven bricks in our bathroom so that we can tile as well as paint. My question is:
What is the exact, best and safest method of doing this?
I don't think gluing-only is sound, and battens will take up a lot of space (I think). Someone mentioned zee furring, though I don't know how that would work. I am looking for a sound method that does not require a lot of space lost. Perhaps a 30mm max? Also, what type of hardware would one use to fix any battens/furring/etc?
We have had quotes from renderers in the thousands of dollars, so that is not an option.
