I was asked to get some information concerning installing magnesium oxide wallboards. It's a material I just got to know and never worked with, so I want to learn what are requirements for installing these, specifically:
- Do I need to make special expansion joints, and - if so - what material is best for to fill the gap?
- If expansion joints are not needed - if I fix several of these with some kind of glue (or other compund) so they will form a larger surface - do I need to make some expansion joints then?
My question is about indoor-related works as these wallboards are seens as a substitute to drywall. Any related info (e.g. install manuals) greatly appreciated.
I need answers from hands-on experienced DIY-ers best. These wallboards aren't popular where I live, so I try my luck here, in DIY SE :)
