efflorescence in a smal area
i'm in the process of cleaning up, and gradually finishing my basement, and was planning on starting by painting the cinderblock walls with dry-lock. i haven't had water problems yet, but i figured i'd rather spend a few bucks i didn't need to rather than cheap out and wish i hadn't later.
anyway, i'm cleaning the walls real well, and i notice some white deposits on some of the bricks, seems to match the description i've read of efflorescence. the thing i'm wondering about though, is i only see it in one area, about 7 or 8 bricks, 3 rows high starting at the floor. i was wondering if this was some indication of somthing else i should be aware of, possibly outside the basement?

This white spot area could be caused by many things. But my bet would be acid from the brick. If the brick was made from soil with a high acidity in it, over time when the brick became damp, the acid leached out. This is not at all that uncommon. I would just wipe it off and see where it leads you. It might also be mold or mildew. Wipe it off with white vinegar and watch it. Not much to be concerned with at this point. Good Luck
