Painting basement: Drylock over drylock

Point being, I'd use a latex based paint to allow the wall to dry when left uncovered from insulation. Drylock will force any outside water to find an alternate route in to your space using the next easiest place, slab, etc.

Gary, if you don't mind, I'll finish your excellent point. OP, do vapor test. Take a piece of plastic about one foot sqaure and tape it to the wall, seal it tight on all four sides, wait a couple of days. If there is condensation on the plastic your getting moisture through the walls. Good point Gary.

Ok. Yeah, I thought I had heard that before. You can clearly see that they painted it over old paint but what's done is done.

Interesting. Does it matter that it hasn't been particularly rainy or humid out the last few days? IIRC there was a little bit of mold along the bottom of the walls that I bleached off when I moved in. It hasn't come back and that was a year and a half ago.

BTW, I mentioned getting water in the OP. This only happens after prolonged periods of heavy rainfall. It only comes in at the base of the wall (on the opposite side of the house that the picture was taken) and even at it's worst has been manageable amounts.

Ptron, water coming in during rain and moisture transfer can occur simultaneously. It's like a leak in the roof, even during a light rain, the leak is drawing water, it's just being absorbed by the substrates inside the leak. When it rains hard they get saturated, overflow, and it comes through the ceiling. I would at least test first before you paint because if moisture is transfering through the foundation, your efforts will be in vain, at least in the area of the breach.

Thanks. I'll give it a try.
