My basement currently have 2x4's framed around. I just stripped off the the old wood paneling and noticed some efflorescence and some damp/wet areas on the wall. Nothing pooling or substantial.
I want to refinish the wall, and add insulation.
I was looking to clean off the efflorescence and put something on the walls to resist water (don't know what yet).
But in insulating the wall (interior), should i go with something like DOW Blue Styrofoam or anything Styrofoam, I don't want to use foam as I am a bit apprehensive either doing it myself, or the price of paying somebody to do it.
