wrote:
I am planning to build a walk-in closet in my basement, to be used for
storage of various items. My basement is currently unfinished, though
I had painted the walls with drylock to try and reduce moisture,
which is an ongoing struggle. I would like the closet to be as close
to "moisture-proof" as possible. I was considering using 2x4's for
framing, and plywood for wallboard (instead of sheetrock). As a vapor
barrier, I'm considering lining the entire closet with 6-mil plastic,
sandwiched between the plywood and the 2x4's. Has anyone tried using
6-mil plastic to prevent moisture from entering a closet? any feedback
is appreciated.

You will never stop moisture from the inside. If you have a moisture
problem, you have to stop it from the outside. First you have to keep
excess moisture away from your home. That means the ground all the way
around your home must slope away from your home at least 10 feet and I
suggest 20. If that does not do it, then it starts getting expensive;
digging out around your home to provide proper sealing of the exterior walls
and drainage at the bottom of the wall.

As for the closet, if you really want it in the basement, I suggest
making it free standing (not sharing a wall with an outside basement wall)
and providing forced ventilation bringing air in from the living area of
your home.
