We used 1/2" thick 4x8 sheets of flat pvc.....(in stock at DBS)
First we got all the sheet stock pvc, screwed and plugged to the bottom of the floor joists...we then covered the seams where sheets are butted and the perimeter with batten strips of 3/4" x 2 1/2" pvc.
.... you might want to consider using the pvc t&g beadboard....not the 4x8 sheets......it's 1/2" thick x 5" wide ...it would a little easier to install than the sheets especially if doing by yourself. I got a piece in the shop so i went out a took a picture for you.
You can blind nail it and not need screws and plugs.
