    Hi Experts / Professionals and Experienced Trademen,

    We prepped the stone wall by removing most of the old wallpaper but it's an uneven wall. Once all the old wallpapers were more or less scrapped off, we then applied PVA glue and plastered the wall with just sand and cement which we mixed ourselves. We applied several coats until it was about 8-9mm thick and as it's an uneven wall, it's still not even and in some places it stands out around 5mm proud. Ignoring the fact that it's an uneven wall, we decided to clad the wall using the bathroom PVC panels with corner trims but noticed that the claddings were not really lined up with each other so we tried to take them off and only to find out we were taking some of the cements off with them as well :(
    After complete removal (ripping) of pvc panels, the state of the wall is now horrendous and you can see some patchy areas and we could do with lots of wall fillers. Some areas will need at least 8mm of plastering. What would you use here to fill the gaps and smooth out the wall again.
    After several days of thinking on how best to tackle the issue and surfing the net for possible solutions, we have found out the best way is using dots and dabs with 9mm plasterboard and the use of drywall plugs and nails or screws. This will save our time fixing the wall or not?
    Can someone please out there recommend the best way forward? This stone wall is part of the bathroom so we will install the PVC Wall Panels again once the wall is sorted

    We will post picture of the actual wall soon.

    Regards,
    Simon

    Have you considered strapping the wall out to fix your gyproc ?
    Aquapanels are quite unforgiving as they need perfectly true, plumb walls to fix to...

    True, but the ones we have are Geo Panels 5mm thickness but they also need true plumb walls unless of course we put plasterboard without fixing several holes in the walls which means we would need a lot of pollyfillers :(
    Yes we have already considered Gyproc Drywall or Stud Adhesives with screw or nail plugs.
    Would the backing plaster be able to level the wall?
    Which one is the cheapest option?

    Cheapest and quickest would be dot n dab.

    What would you use for dot n dab? Would this alone be enough to hold plasterboard in place? The wall is 2.5m x 1.8m.

    drywall adhesive...fix plugs through the dabs if you are going to hang any large format tiles from the sheets.

    OP,
    As a professional walking into your bathroom I would look for any damp signs inside, and render on the outside.
    Presuming an outside wall: I'd ask if the stone wall had given previous difficulties.
    And I'd hack off back to bare masonry.
    Then, after any dubbing out, I'd pull the wall out with two coats of sand & lime render which should straighten it up.

    Stay away from D&D and the rest - you might give yourself damp and/or penetrating salt issues or knock-on issues.
    The straightforward, traditional way to provide a safe, effective backing for any size tile is render.

    Ignore the doom and gloom merchant, he likes to create problems where there are none.

    Dotn dab to install your panels on will be quite sufficient and diyable.

    This is no issue with the wall and there is no damp at all. The wall is in fact used to be external but now internal as we have built a single lean-to extension on it and extended out by 2.8m. It was plastered ok but was still uneven. We are thinking of fixing it by re-filling the holes with sand/cement mix and smoothing them out.
    Sticking Geo PVC Panels on to the wall was a success but because they didn't line up, we had to ripe them all out and as a result, some plasters came off as well.

    Using dot and dab with plasterboard would make the wet room a lot smaller and some of the water and waster pipes are in the way too.
