I have a brand-new section of marine grade carpet that I purchased for refinishing my pontoon deck. It is a brand new, blue, 32 oz weight, with a rubber backing that is designed to be glued down.
I had to purchase a roll much larger than I needed. The original roll was 8' x 12' long. After I cut out my section, the remaining piece is 4' wide x 12' long with a small L section that is 4' x 4'.
