Hi, New to the group here. I'm just starting the process of renovating the basement and have found the answers to many of my questions on basement drywall and furring strips already by going through the archives. My job is made harder by the fact that 15 years ago I did my first effort of installing furring strips and drywall and did a fairly sloppy job. Before I can start again I have to deal with fixing past sins. First, I installed the original 2x2 furring strips by pounding masonry nails into the block. Unbelievably it appears I dodged a bullet and the blocks did not crack. 1) Should I try to pull these old strips off the wall or will that do more damage than leaving them in? They really were put in sloppily and are not in the best locations. Also, after stripping the old drywall off the strips I have a dried bead of liquid nails sticking up. If I leave the old strips in and put better ones around them the liquid nails is going to be sticking up above the new strips. 2) I do want to put a few outles in the wall. Assuming I use the 2x2 furring strips you suggest how do I thread the electrical cable through the strips? Just predrill a hole through the side of the strips before mounting? 3) We've lived in this house for quite sometime and the walls are dry and it's pretty warm down there without insulation. Do you suggest installing a vapor barrier before putting the drywall in? Thanks for the help.
