I'm putting PVC 4x8 sheets on the ceiling outside to a front door (alcove). After their installed, tongue and grove boards will go on the side (vertically). When I install the ceiling I will use construction adhesive to go against the joist. My question is how do I go about nailing? My initial thought was to use a trim gun and making sure the setting didn't blast through the PVC sheets. But I'm a little concerned that may not work. The reason I'm using PVC is to create less maintenance in the future. I will never have to replace the sheets unless they crack, all I may have to do is repaint.
