Probably a simple answer for you tilers.
I want to tile a fireplace (just the wall surrounding a gas fire.) It's an old house and the wall is very uneven. Was thinking of fixing some pink plasterboard and then tiling onto that. Do I prime the pink plasterboard with something or can i tile straight onto the plasterboard?
Tried to look it up and all i can find is the PVA argument but all them cases where when tiling in a shower or other high moisture areas.
Thank you all in advance for your time answering
