Moistureproofing shop - now stage box

[Bob Hull]

I appreciate the reply, Gordon.

My concrete floor does have a layer of plastic
sheeting under it, if I remember right.  What type- I
don't know.  

I have seen moisture still come up through some small
cracks and the concrete will look damp around that
crack.   But, overall I don't think I have a big
problem.  I'm still getting the inside walls sheathed
with plywood when time allows.  The building is a
metal building that began as a horse barn.  I added a
ceiling, interior framing and insulation.  I've just
used the localized approach of multiple dehumidifier
bars and blankets draped for drying out soundboards
and this seems to do okay.  

I think next spring an additional or new dehumidifier
unit will be in order.  


I'm outa here for the day.
