Fitting Marmox board onto plasterboard?

[mono]

Hi all,

Can I mount Marmox board onto plasterboard, and what method would you advise? I could remove platerboard and mount onto stud but I know the studs aren't suitably spaced meaning adding more timber (every 300mm)

I did this yesterday on a smaller wall after some good advice off this forum, but this wall is much larger and if I can I'd rather just go straight onto the plasterboard. Obviously want to get this right so will rusted if I have to, juts after some opinions or advice.

Thanks.

What are your reasons for the marmox ?

Is it weight limits or tanking.?

Hi,

It's for tanking. Haven't selected tiles yet but don't anticipate they'll be anything out of the ordinary.

Already got the board so looking to use it along with the showerlay tray.

Ok.. just there are other methods..

What thickness of boards did you buy.?

 

[mono]

10mm

I replied to your PM , was quicker than awaiting your post approval :lol:... mods are asleep .

Haha, thanks for that. I thought that there was something wrong with the refresh button!!

So, adhesive and screw into the plasterboard/studwork? Will the boards take up any unevenness in the walls without issue if they are fully bedded down? The walls aren't too bad but aren't perfectly flat either.

You can D&D them but fixings must go through the dabs.. or flatten walls off first..

Hiya Mono.
As Dave says, i dunno what area you are doing, but if it's a shower make sure you'll have enough room for the tiles and the showerscreen to fit.

Hi Bugs,

Yeah, it's the shower. All good for tiles and screen. Next question is the floor:

I'm using a shower lay former (20mm) but because the floor was not level I had to sink it into the floor and hang off the joists to level up. This has left the showery tray sticking 10mm proud. Can I use the 10mm boards straight onto the chipboard floor, or would I be better with no more ply or similar?

Thanks, great forum this.
