I am refinishing my basement, starting with cinderblock walls and existing framing, which previously held luan-type wood paneling. Cement floor. I have minor efflourescence on the lower seams of the block wall in one corner, so moisture is a concern. I've never had actual flooding down there. I also have a dehumidifier which drains to the pipes in the half bath in that area. I'm planning to paint the walls with drylock first, put hard pink insulation between the existing framing, then put up walls. My question is, what are the pros and cons of various materials - drywall (mold resistant variety), paneling, plywood...any others you know of? Main considerations are the moisture and that I'll be using this as a music studio, mostly rehearsal, maybe some recording. Thanks.
