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.Steve |

| 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... |

| 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.. |

| 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. |

| 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. |

| 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. |

| 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. --Vic |
