Hello. I’m planning on half boarding some walls with 3mm MDF as I plan on using some 8mm MDF strips to create a wainscoting effect. I could just put the 8mm on and paint but the walls aren’t terribly smooth hence using 3mm. I’ve never done anything like this before and was just wondering how you would advise attaching the 3mm? Would just adhesive suffice? Also could I use an electric nail gun and if so will it go through any surface? Again sorry if any of these questions are dumb. Thanks in advance!
