Hello,
Well, this was supposed to be a brilliant scheme. I recently developed my basement by rough drywalling the framed walls, stapling up tar paper, nailing on stucco wire, and covering the whole thing with a mixture of hybrid adobe (which consists of 50-60% pulped recycled paper, 25% earth, and 15% cement). It looks fantastic. However, for my first few loads of adobe, I must have skimped on the cement and not mixed it enough, because there were patches of pure pulped paper on the wall that didn't turn hard. This adobe stuff takes up to a couple weeks to dry fully, and as a result, those poorly mixed paper patches started growing orange mold. Fine. So I figured I'd just paint over them, hoping the toxicity of the paint would kill it. Nope. So finally I removed the orange patches down to the stucco wire and tar paper with the intent of slapping on some proper mix over the problem areas, but I noticed that in these spots there is some mold growing on the tar paper and a bit on the actual drywall behind it too.
So, my questions are:
1) It's not black mold. Is it that bad? Do I need to worry about it?
2) The source of moisture is now gone (because the adobe is dry). Can I just get rid of those orange mold spots, spray a fungicide over and around them, and re-seal my wall and leave it at that? Even if there is some mold left behind, I'm guessing it will remain dormant because of the dry conditions.
Having to rip apart the walls would be an incredibly difficult and time-consuming task. It's the absolute last thing I want to have to do.
Suggestions?
Thanks.
Luc

Not all mold is bad.
You may have just a staining mold and if the conditions are dry as you say they are, then all you may need to do is cover the stain with something like Kilz and then paint. I would suggest a permeable paint so that the wall can breath inward.

Thanks for the reply. I talked to some mold remediation people here and they said that Borax does a good job of cleaning up mold, so I took apart the adobe where the stains were showing up and wiped down the drywall with a Borax solution, then slapped on some pure cement. I heard that mold doesn't like lime, so hopefully this will work.... At any rate, everything's dry now so what's there behind the wall won't spread.
cheers
