Framing "basement" walls - moisture protection?

Coastal SoCal. No HVAC or insulation needs. Not a true basement, but a detached building built into a hillside such that most of it is underground. The building walls are concrete, and I want to frame it out to build plywood walls for ease of mounting french cleats, storage racks, etc. vs. bolting into the very old concrete. I plan on painting the concrete with a couple coats of Drylok and doing the framing with pressure treated lumber. Is that enough, or should I also install plastic/Tyvek/some other moisture barrier between the studs and the wall? Only if they touch? If so, what's the easiest way to do that? I probably have to frame the wall in place due to space constraints. submitted by /u/deeyenda [link] [comments]
