I have a 9-year-old cement foundation, that is 24x50 and live in New Hampshire. One full length of the foundation is an exposed walk-out with wood walls. The other 3 sides are cement and mostly underground (approx 2 ft exposed above ground). I have no water problems and have a French Drain around the foundation. The walls are always dry. The basement
has low humidity as I run a dehumidifier in the summer and a woodstove in the winter. My ultimate goal is to drywall or panel over the cement walls and never have to do it again.
Thinking that it would be a simple project, I have nailed 2x3 furring strips (flat-side against the wall) horizontally along the base of the wall and the top of the wall. I then nailed 2x3 vertical furring strips (flat side against the wall) every 16" on-center. The furring strips are kiln dried and not treated. The cement wall has not been water-proofed. Since nailing on the furring strips, I have heard conflicting reports on what to do next.
Questions: Should I Tear off furring strips and start over (I would really hate to do this)???? Should I waterproof the cement wall??? Should I a
dd rigid insulation
between furring strips??? Do I need to add a vapor barrier??? If so, is the VB
to be placed between the furring strips and drywall/panel??? Any advantages to paneling vs drywall??? I want to make sure I do this project right, and not create mold/moisture problems that I will later regret. I would appreciate any advice you can provide. Thank you very much.
