Thanks guys.
Honestly, I'd like to avoid a lime plaster if possible.

I just sprayed the walls with a bleach solution and the mold immediately disappeared in most places, except where there was some dark growth.

Next, I intend to re-plaster the remaining walls and ceilings with a commercially produced wallpaper adhesive instead of flour paste, due to the fact that it has a mildew-cide in it. I also intend to add borax to the mix.

I'm not sure in what ratio though as it's been a long time since I've used it in plaster (suggestions welcome). I then intend to paint all the walls with a lime-wash in hopes that it alters the surface pH to be less hospitable to mold and mildew.

The existing recipe is 2 parts fine play sand, 1/3 part 200 mesh silica, 1 part kaolin clay, 1/4 part flour paste, 1/16th part titanium white, and a pinch of control fibers.
thanks again

Hey y'all
I'm in humid Georgia and just put up a natural plaster recipe onto drywall.  It's a recipe that I used to use in California without a problem.  Unfortunately it's been really wet and rainy here and 90% of the walls now have a fuzzy mold on them, which is no bueno at all.  I was thinking of either bleaching them or painting them with lime water and then potentially re-plastering them with the same mix that has borax added to it.  I haven't done much natural building in almost 15 years though and I'm very limited on time (running an organic farm during peak season while doing this), so I can't really go through much more trial and error than I already have and I'm currently way behind on finishing this necessary building.  Any experienced recommendations would be greatly appreciated.
Thanks in advance,
Steve
