I bought and prepainted composite chair railing for my den. When I went to install with a nailer I found out my interior walls have studs 24" on center. Given the long distance between nails the railing will tend to gap. Do I have any alternative ways to install? Will some type of glue help? Not sure how to hold while it dries! I searched this site and have not found someone with a similar issue. It is a small room (11' by 11") and the outside wall has normal 16" studs. Any help is appreciated!
