Does anyone know of a concrete nailer that actually works to nail down tackstrip to concrete? I purchased an expensive PNI pneumatic t-nailer a couple of years ago, but I had the same problem with most concrete that I have when hand-nailing. If the nails are too thin, they bend, or chip out the concrete. I even contacted PNI to see if they could tweak the gun to shoot 10 gauge nails, but after numerous emails back and forth, nothing ever came of it. Any suggestions?
