Help with magnesium oxide board installation[edit]

please any suggestions for the proper jointing compound required for the boards also what type of material is used for the skimming of the the boards?41.219.220.112 (talk) 23:41, 29 January 2009 (UTC)[reply]

It is best to ask a question like this at Wikipedia:Reference desk/Miscellaneous. Graeme Bartlett (talk) 01:58, 30 January 2009 (UTC)[reply]

water/moisture resistance?[edit]

What's up with those claims? Magnesia does react with water, after all, and even dissociates into Mg2+ and OH- ions. I suppose the pressed material offers very little surface area for that, but "waterproof" would be quite strong a claim.

I would guess it's similar to how aluminium forms a passivation layer and is quite hard to dissolve except in the presence of catalysts such as mercury.

What's the effect of acid rain or H2CO3 (worse, a combination of the two) on MgO boards?

'Disadvatages' section reads like an advert from one of the biggger suppliers in the industry, the language should be changed. — Preceding unsigned comment added by 86.132.24.130 (talk) 12:29, 17 December 2011 (UTC)[reply]

Rosendale Natural Cement non-fired?[edit]

The article about it: https://en.wikipedia.org/wiki/Rosendale_cement says that it is "calcined" (~=heated) in a kiln.

So if they're the same thing and that page is right, then the claim here that it's non-fired is wrong.

I think that what's natural about it is that the manufacturers found geological sources of appropriately pre-mixed minerals. ArthurDent006.5 (talk) 07:50, 3 January 2016 (UTC)[reply]
