Cement board to drywall

I was confronted with the dreaded laminate Pb wall a few years back. Think it was 2 9mm boards with something like 20mm board in the middle. Pissy wood frame around the edges, nothing running vertically in the middle.

It was all coming apart, but the lounge was on the other side and all well papered. Carefully removed the layers leaving one 9mm wall papered wall, dabbed the middle layer back on then bonded osb on, before tile backer boards. No room to build a stud frame as bathroom was tiny and there was a wall hung basin to be fitted and grab rails.

It’s obviously not the only way of doing it Andy, but had to find a solution there and then as I had a tight deadline to get it done as the old lady was coming back out of hospital. Osb was half the price of what it is now though. I’d rather be confronted with paramount board tbf, as at least there is a bit more in the way of studs to fix to.

If I'm reading correctly that's 4 layers on the wall that will eat into my 800 shower tray and create a step in the wall that continues bathroom side of the recessed shower are

Yes. The top layer of Pb is off, then osb and board. It adds about an extra 20mm. You obviously have to do complete walls. The one I showed, I did it to 3 of the 4 walls. On the 4th, there was a small towel rad going on, so I bonded some strips of ply on as the middle core before the Pb to get a solid fixing. There weren’t really any other options.

You could probably just bond your boards on with instastik. I’ve used it on a few jobs and it’s brilliant stuff.
 
We are getting somewhere.... im thinking CT1 some pieces of wood to each side of the middle pb and use them to fix and support the aquapanel...... aquapanel is only going up to a height of 1.2m should be a solid fix for it along with added dab..

I’ve told you how to do it, but may have misinterpreted where you’re at. If the middle layer of Pb is still attached and virtually flush with the stud frame, then just clean the dabs off, get some instastik foam and bond osb over the top. You can get a few screws in around the edges. You can then screw on whatever backer board/Pb you want and you’ll have a really solid wall (relatively speaking) I’ve done it before.

Failing that, build a new stud wall.

Don't think he's listening to ya mate horse to water and all that
 
Mate of mine did that, he used sbr on the back of it hoping it'll help it bond, it all came off the next morning...

Hi bud

Don’t use gypsum dab adhesive with Aquapanel, the suction in Aquapanel pulls the water out the gypsum adhesive so it effects the cure (will work but not as strong) but issue more with moisture from the shower re-activating the gypsum dab adhesive later and tiled boards being heavy might just pull and fall off… use tile adhesive if you have to dab Aquapanel

Hi bud

Don't answer such old questions, the work will have been done long ago. Thanks for trying though.

Hi all just stripped the ensuite! The recessed shower walls (built in cubicle) have no studs, instead the builders who built the house placed a peice of drywall inbetween 2 plasterboards of all internal walls by the looks of it! Anyway..... ive taken off the 'face' plasterboards in the recessed shower are and now I am left with the bare internal plasterboard (the one sandwiched between 2 boards) looks like everything was dot and dabbed to each other! I've removed the dabs..... how can I fix Aquapanel to the plasterboard baring in mind there's no studs! Can I use drywall adhesive to dot and dab to the plasterboard that was sandwiched? And then screw into the dabs when hardened for extra support?..... hope I've managed to explain! Thanks

Crispy is right, there is a frame right around it, can see it in the pics. I'd rather rip the lot out and put a proper stud wall in, but you seem intent on bodging it. For some reason I'm liking the idea of stiffening it all up with an OSB 3 board first if your not going to do that.
Then Glassroc H full height, with or without the OSB. Don't feck around with part-way in Aquapanel - take it back and get your refund.
