Question: covering the marine plywood thoughts
I am building a houseboat and trying to understand the concerns with covering marine plywood with something like a rolled vinyl. The product is cheap enough that thinking to put on top for sure and maybe even underneath before installing floor.
1. Are there any negatives to this idea (like trapping moisture rather than avoiding it)?
2. Would I be better off rolling some sort of epoxy product on top/bottom/sides?
3. Should I spend the money and use a composite decking like Trex?
My goal would be to get about 30 years use.
Appreciate anyone thoughts.
Thanks
Joe
