I've boarded out my new wetroom with Marmox 20mm boards, but the missus is thinking about a change of plan.... to have some parts near the sink plastered, so is it possible to plaster on Marmox? Or do I have to replace the boards with traditional plasterboard/moisture resistant board.

Cheers, Warwick.

Why? is it so you can paint

I'd try and talk the Mrs out of it

Pretty much yeah and to break things up rather than have the whole room tiled, plus less tiles = less £s too

Loathed to rip off the board if it can be plastered over

Yes, pretty much, now she would like the top half of a couple of walls painted & less tiling = less £s for tiles.

Would like to avoid ripping out the Marmox and replacing if possible, so any ideas?

Yes it can be skimmed

Thanks Dave, in a "regular" fashion like on plasterboard?

I stuck the board to the wall with plaster, and it's stuck well so a skim should be no different

What kind of plaster did you use to stick with ????

hi warwickgooch

as dave said, yes they can be skimmed but you should have used a single part felxible adhesive to stick them to the wall, not plaster!

prime the marmox boards with SBR or acryllic primer. wait till the primer is tacky, then skim away.
