Before i get it wrong i want to get it right!

Thanks for that Dave, just run though the dowlling through the dabs😳

Seems sorted now, or you could entertain the idea of D&D MR plasterboard and then tanking fully. Might be easier to get your levels flush?

Why not batten the wall that will take the 12mm HBB so that it will finish flush with the plasterboard when the HBB is fixed to it. Use self tapping concrete / frame screws through the HBB & battens into the brick behind.

this is what i was thinking, but im not confident that i can get the adjustment to get them level as i can with the d and d method, given that the brick work isnt that good.

Dave has given you the solution to your problem.
Dab a waterproof board on to the same thickness as your plasterboard.
Job done.

 

[little ed]

Yep this is what I think I will do thanks for everyone's advice

mm perfect ..?



Me thinks not..

yes you can D&D PB .. and then tank that .. i assumed backerboard was the option.. but PB tanked is as well 100%

Hi again, backerboard was my option and u was going to tank the backerboard to be confident it would be waterproof. Is plasterboard tank would be ok I might use moisture board and tank that. Would that be ok??

 

[DHTiling]

if you are tanking it , then normal PB is fine.
