RE: [papercreters] Re: fermented paper / was Several hundred pounds of books

I think this dicussion got started when someone said they left their paper in water for a long time. Then someone else said don't you ever have a mold problem.
 
I have had one experience with mold. I formed up a curved wall that was actually quite thick. I used 1/4" plywood cut in half to form a 4 foot square. I wedged it in to curve it and poured it full of papercrete. I can't dexcribe the shape of it but it was sort of triangular and held a lot of slurry. I left that form on for about almost a year I think. I had moved on to other things and just sort of forgot about it. Anyway, when I took the plywood off there was an area of black mold on one side of the wall. It was small, maybe 2 square inches or so. After it was exposed to the sun for a while it went away. The mold was on the plywood more than the papercrete so I think it was the plywood that infected the papercrete.

This discussion makes it sound like mold is a big problem with pc, whereas I have never had any mold problem in all the pc I have done, which is a considerable amount. Even when I let a mix sit in the mixer for a week all I got was a slight smell and a little bubble action from bacteria/yeast/whatever.

Mike McCain helped make a facility for growing mushrooms in CO, and they kept a hose running on the pc roof all the time to keep the interior humidity high. There was no mention of mold.

Has anyone on the list actually had a mold problem or is it just something that we talk about as a possibility?

Ozone generators do a fine job on mold.  There are lots of build instructions to be googled.
