Pros and cons of painting basement walls in the unfinished sections?
Certainly a fresh coat of paint costs little in money, time, and effort for the difference it makes as an impression on your potential buyers (do the floor too for best impact.) I've done this, and heard from the realtor afterwards...
If you choose a light color (or white, my personal preference) it's much brighter, dust from raw concrete is reduced or eliminated, and it does not cause any detrimental effects if finishing is later contemplated.
I use flat, not gloss as it minimizes rather than accentuates the surface irregularities. Personally I like latex base concrete paint (easy cleanup, easy to recoat if ever needed) but I'll stop short of the brand recommendation. If your &quot;water issues&quot; are not interior, use the &quot;waterproofer&quot; variant of the paint (less coverage, thicker, entirely compatible.) Not a miracle, but I've had it hold minor leaks for years (serious leaks will beat any interior coating, IME.)
