Cob: Cob/Lime/Borax/Mold/Follow through

[D.J. Henman]

Kim,
    I am not sure that the mold itself is a problem. The walls will 
dry.   The main problem of mold  is that it might cause color blotching 
through a final thin finish.  What you could do is just let it be until 
the walls are well dried out then go along with a light grade sand paper 
and scape off the mold.  Then dampen the surface a bit to get a good 
bond with a final coat and apply a thin final rendering coat, which will 
dry  relatively quickly.
