I recently removed my basement drywall and the old insulation behind it. The basement was first finished about 30 years ago (by old owners).
The walls are concrete blocks. Most of them are fine, but one corner clearly has some moisture issues and some mold. This is near the only part of the house where the soil isn't well-graded outside so the location makes sense, and I'm going to fix that.
I was planning on re-painting the walls with some Drylock paint and also some anti-mold paint before having the walls spray-foamed (with closed cell foam).
I've had a lot of luck with this anti-mold paint on bathroom ceilings. I painted one five years ago and the ceiling still doesn't grow any mold.
Does it matter whether I put the Drylock on first or the anti-mold paint? Does the Drylock have to go right up against the concrete and get absorbed or something like that?
