Finished Basement Walls(exterior)

hey guys, I have a pretty good system for doing exterior walls in finished basements. Most of the basements in my area are block, or poured.
The newer houses are poured.

Do you guys that use foam board insulation, install drylok waterproofting paint on the concrete or block first? I think this could be a double vapor barrier so if the basement is dry, I just put the foam boards against the block, tape the seams and then build my wall right up against that. I don't use plastic behind the drywall either.

Do you think it's bad to have drylock then rigid foam insulation up against it?

I won't use fiberglass insulation in basements anymore.

Nope, not at all...Drylok is similar to Thoroseal which i use and are negative side waterproofers. Thoro claims to breathe vapor anyway and good choice on the rigid. U use steel studs/furring for the framing or still using wood?

Re: Finished Basement Walls(exterior)

I still use wood unless it's a damp basement. I guess I haven't ventured into the steel stud world yet, but it's something that I'm not opposed to. I am going to bid this next finished basement with steel studs and see how different it is to work with. What's the best thing to cut them with a cutoff saw or are they thin enough that you can use a fine tooth carbide blade in a miter saw. I have an older non slider dewalt miter saw that I use for cutting aluminum with. I was thinking of using that.
