Marine or regular plywood

I live in a dry area. I want to replace some wood on my boat. Is marine plywood an absolute necessity, or would a good grade of sanded one side suffice? About the only time it would get wet would be when it is outside and it rains, and we get less than two inches annually.

Hummmm, however many manufacturers use a rubber putty instead of real wood. It's a joke but to Steve, use marine ply on a boat... JustWaitAFreki...

He did.. In the old days they used to "encapsulate" wood with epoxy. Water will get in, and the result will be it can't get out.. JustWaitAFreki...

You need the marine when you are doing structural mostly. Supposed to be there are no voids inside to trap water. My floor lasted 17 years and was Pressure treated ply with Nautilex vinyl covering. Calif

Of course it is. Navy, Air Force and Army plywoods just inferior.

If you want the job done right, send the Marines.

Marine grade plywood typically has the voids filled as each layer is added. You see the void filler on normal plywood only on the outside layers. When I replaced my floor I selected a plywood that was not pine rather than focusing on marine grade. Right or wrong, I left the underside unsealed so that it could dry when it got wet. I also removed the foam and did not refill with foam. The foam traps the water against the floor. I added drain holes through the stringers. I boat in SE inland lakes so the flotation is not much of an issue for me. I have heard as alternatives to the foam, the use of 1 liter soda bottles with the caps on them as well as cut up sections of those kids noodles. jamesgangnc

When I was considering redoing the floor of by brothers old glastron. I ripped out what was left of the flooring and was amazed at how much foam wasn't under there. Yes, just a few little strips of the white square Styrofoam like stuff.

Not enough to even dink with.

With wood. Look at the surface of good plywood. You will see the biscuits they used to fill a defect. Marine uses the same method on inner layers. Calif

Don't know the answer to whether or not to leave the underside unpainted on a boat floor. But when I rebuilt an outside porch once with tongue and groove pine I primed/painted both sides. Wouldn't believe how fast that floor rotted. You probably did it right.
