Subject: [Mgs] Mold, part 2

I have received many great suggestions from the list. A simple start will be to create a moisture barrier between the concrete floor, which at present has a carpet, and the MGB.  This will be in the form of a tarp or plastic sheet.  Excuse my naïveté but what prevents moisture from forming on the tarp or plastic?

Theoretically it will form on the underside of the plastic=E2=80=A6 =
which will not be good for your carpet, which should be removed.

Leave the cover off for ventilation, as much as possible (obviously you =

Bob is right, in that ventilation is the key.
