Anyone had any experience using magnesium oxide boards as a gypsum board replacement ?

Question

A list of US suppliers is here w/ some discussion. http://www.concretecottage.com/Magnesium-oxide-boards.htm

I need advice on how to hang it as wallboard, ceilings and floor tile underlayment.

Answer 1

Haven't experienced it but from what I read in your link, it gets hung/nailed like drywall and underlayment.

If you're not familiar with how to hang drywall, the first link is a very informative step by step video.

Second link, though not a video is how to install cement board/fiber underlayment.

Hope this will be of help to you - good luck!
