kiln dried pressure treated plywood

Is this the same thing as marine grade? When researching this, it sure sounds like it is.

Any body know for sure.

And who in the metro area actually carries kiln dried or marine grade plywood?

I think they are pretty much the same. I have used green treated 2x4's under carpet for bunks on my drive on trailer. They have 7 years on them now and are just fine....I know one thing, its a lot cheaper buying green treated lumber at Menards than buying marine grade wood at a Marina! I would go with the green treated at Menards or Home Depot!!

The main difference between marine plywood and exterior plywood is that marine isn't allowed to have any core voids. Any good DRY treated plywood is adequate for most boating needs. I would only reccomend using marine plywood if you are building a wooden hull and even then I would use exterior for the framing

Not building a boat, building a fishhouse and looking at what I should use for the floor.

Right now I am looking at going with Kiln dried because it is already preshrunk and much lighter. Going to be carpeting the top side with outdoor glue and carpet and most say the glue is enough for a waterproof seal. For the bottom, I am thinking about coating it with truck bed liner paint.

korn_fish,

I have a suggestion for you, when you put the floor in your fish housemake it a sandwich construction. The last house I built, I put 1/2" plywood down, then I put 1" dense styrofoam, then I topped it off with 3/8" plywood and Juteback (sp) carpet. After the house gets warm you can walk around in your stocking feet and they'll be warm. It made a huge difference.

I didn't use green treated or marine plywood, I bought the cheapest stuff I could find and painted the heck out of it on the bottom side.
