I'm planning on slowly refinishing my basement. I'm drywalling & would like to put wainscotting (sp?) and a chairrail. My question is, do I put the wainscotting on top of the drywall, therefore adjusting the amount that the electrical boxes stick out of the wall during the rough-in phase? OR Do I drywall down the appropriate disstance, and secure the wainscotting directly to the studs below?
