I'd like to finish my 56-year old garage with drywall but I have concerns about moisture.
The wall construction looks like stucco over tar paper with metal wire support, then the frame.
My main concern is that when it has rained in the past, the inside of the stucco and the tar paper gets moist. On some parts of the wall, the paper is torn and I can see the stucco from the inside. If I drywall the interior, will the moisture still be able to escape and not cause moisture damage or mold?
Are there certain kinds of insulation and/or vapor barrier that would allow moisture to escape?
I have read that using an impermeable membrane could cause condensation and cause water to pool at the bottom of the wall.
