I am finishing my basement off. It is currently unfinished with concrete (slab) floor and cement block walls. My basement is VERY dry. I've never had any problem with water or any type of moisture problems.
Question #1.... Do I need to paint some type of water solution on the wall's before I start building my framed wall.
Question #2.... I've been told to use insulation that has a vapor barrier built into the insulation, and that I should not use plastic between the concrete walls and the frame (I've read that moisture vapor has to pass through the wall). Whats your thoughts? and what should I do? I keep hearing different stories and I'm confused.

I think they are talking about the green fanfold insulation. It has a plastic coating around it. This vapor barrier for some reason is always a disputable area. The code books say that the vapor barrier must be next to the concrete. This prevents moisture from getting into your wood and insulation. If moisture gets into the wood or insulation, mold and mildew sets up. This makes sense doesn't it. Good Luck
