Do I need to prime marmox ? - TilersForums.com

[dholdi]

I've been doing a bit of research prior to tiling my bathroom.
3 walls are lined with marmox boards and the fourth, which is an internal wall and well away from any wet areas, is plastered.
From research on here I realise I will have to prime the plastered wall with Mapei primer G, but will the marmox boards need priming as I cant find any reference to this in Marmox' literature but Mapei's mentions cement board in their primer g literature.
Any advice is much appreciated.

You don't need to prime Marmox, as long as its clean and dust free.......

as above ^^^

Also as above, if the boards are a bit dusty, then a wipe with a damp rag should be all you need

Thanks very much everyone.


Just one more question, my electric underfloor heating came with a liquid insulating primer. Would applying this to the marmox boards on the floor have any detriment ?
I am thinking along the lines of it preventing the adhesive from adhering to the boards correctly ?

I shouldn't have thought so. I prime No More Ply boards before fixing UFH as it helps the tape stick to the boards but i am unsure if Marmox recommend priming.

I wouldn't use it for that reason and it won't improve the insulation values you'll already be getting with the marmox.

Thanks Rich & Stewart,
I think you could probably tell from the question that I was dubious about using it.
Your replies have just backed up my bad feeling about using it.

Thanks Again
