Hi. Have a shower enclosure that is slightly too wide for the tray. It has been suggested to me that I could affix a moisture resistant plaster board to one of the existing plastered walls to narrow the gap. This makes sense, but how would this be done. Can you use board adhesive on walls already plastered? The existing plaster is many years old. If so, which products would I use and what is best practice?
A more in-depth description of the issue follows.
We are replacing the tiles in the enclosure with wet wall panels. The tiles have now been removed and in doing so has revealed a gap varying in width between 2mm-6mm between the shower tray and the three walls. I know that this gap would ordinarily be filled with silicone sealant. My great concern is that the Mermaid Wet Wall panels that we have purchased are only 3mm thick. The instructions state that a 6mm bead of adhesive is to be used to fasten the panel to the wall, but obviously this adhesive will squash down to 1mm-2mm. There are sections where the panels could end up sitting behind the shower tray instead if on top of it. I know that this is a big no no. It was for this reason that someone suggested, chopping out two of to the three walls, (let's say the rear wall and the left hand wall) this will effectively allow the tray to be set into these two walls, thus closing the gap. However, in doing so, as the tray is moved to left, this increases the gap at the RHS. Installing a moisture resistant plaster board at the RHS would eliminate this gap. Which now leads me to another question...I imagined that I would have to then plaster the new plasterboard newly situated on the right, before I could apply the Mapei Shower proofing kit (paint). I thought that this would really slow down the process, because I would have to wait ages until the plaster had dried sufficiently to apply the tanking. But, i have been told that because I am using wet wall panels, I don't need to even tank the walls, probably because moisture can't get in. I guess
Because there are no porous grout lines. Is this true? Can I fix the wet wall panels directly to non plastered plasterboard? Is it really wise to not even tank the walls, whether they be plastered or simply plain non plaster plasterboard?
Sorry, I know there is so much to take in there. Any help you can offer will be greatly appreciated
