Hello, I have been working on my basement (unfinished) when I have free time. I have been installing drywall over the last year and was preparing to paint. I noticed surface mold along the floor line (on the dryall - standard; non mold resistant drywall). I am wondering if it simply caused by the fact that my floor (non finished) is causing the issue and that this situation will be remedied by floor covering. Or (option 2) do I need suspect the worst?
