Hi, I have an unfinished storage area in our basement and it has concrete block walls (that back up to the dirt) and would like to paint them a color. I plan on turning part of this area into a crude exercise room.

Some of the places do, very rarely, get damp.

Not water on the floor though.

I would like to know what kind of primer and paint I should get. I plan on painting the place a sunny yellow.

And, I need to get the cheapest paint/primer that will still work fine.

Thank you so much!
