I have a very dry basement but apparently poor ventilation in
this unfinished storage room. I have a white mold growing on the
lower part of the joists. I removed it about two years ago with
a spray product from Home Depot. It said it would remove and prevent the growth of mold. Well it's back. I'm wondering if I should repeat the process and then paint the joists with a mold resistant/preventative paint. If there is such a thing.
