I'm putting up some walls and a subfloor in our basement. I've read in some
places to put a vapor barrier right against the bare concrete walls, then
stud it, then insulate and put up another barrier. Some other books say to
omit the one against the concrete. I'm thinking I just paint it with a good
basement paint. There's no water coming in, just an overall dampness. I
assume the same goes for the floor? Just paint it, or plastic then stud and
insulate, then plywood over that?





One advantage to having a barrier on both sides of the studs is that you
can wrap around the top and bottom plates and tape the whole thing up,
making it more airtight. Also using an external barrier may offer longer
protection against dampness; it's important to keep your insulation dry.

I used a black waterproof "scutan paper" that was pretty easy to work
with. If you paint, I think you're supposed to grind the stuff into the
concrete with a wire brush.
