[Cob] mold or fungus?

[Marlin Nissen]

me too, my 'moldy white' creases came in projects from the the summers in Illinois and Wisconsin,,,,but they seemed to disappear and/or become just a film as wetter weather disappeared....we weren't in huge hurry to plaster and and wanted to put in that people that covered there Cob projects with plastic ran into worse problems due to trapping moisture.

TMK there was no problem, structurally, with any of these walls after they dried.

Tys,

I experienced a similar issue with small patches of white mold growing on
cob walls before they were completely dry.  I live in south-central indiana,
in a heavily wooded area, and it can be quite muggy in the summer time.  I
thought similarly to you, and sprayed the areas with a bit of bleach water
once the walls were completely dry and before plastering them.  Haven't had
any problems since then.  I do wonder if the mold would have disappeared on
its own without the bleach water, but I was impatient to begin plastering
and didn't want to take a chance.
