Replacing floor board
I have ripped out the floor out of my boat as it was pretty rotted.
Replacing it with plywood is not an issue, should I cover the whole
peice of plywood in fibreglass to stop it from rotting again, or is
there a paint/stain/sealer I can paint the wood with before I carpet it
that would be better and less expensive?Thanks!

| I've gotten small pieces at a local outdoor sign company. I live in
Idaho and they get their's from Portland, Or. I was told that a 4 X 8
sheet of 3/4" was $115 + shipping. You might run a search for
suppliers. Jim

| Yes, a web search brings up a lot of info about it. I agree it looks
like an ideal substitute for regular ply. I didn't have much luck
finding any retail sources on the web, they were all industry or
supplier links. One company was finishing one side of it with various
colors for marine use. |

| Consider HDO (High Density Overlay) outdoor sign material. More expense
than marine ply but totally waterproof. Jim

| I've heard that stuff mentioned before. Where do you get it? I've not
noticed it in lowes. It sounds like a good material to consider for
outdoors sorts of projects. |

| Use Marine grade plywood and cover it with fiberglass both the top and
bottom of the plywood. Use silicon in all screw holes. |

| There are a number of opinions on that topic. One thing I think
everyone will agree on is that epoxy is better than polyester resin. I
find pretty good deals on epoxy at http://www.uscomposites.com/ c0d3phr3ak wrote: |

| Also I'm not big on marine grade plywood if it is still pine. Marine
grade just means it has no voids. That's pretty important for a
transom or hull but doesn't matter as much for a floor. Given the
choice between a better wood such as fir and marine grade pine ply I
would go with the fir. Pine just rots so easily when it gets wet.
Some people advocate pressure treated but it is difficult to get
anything to bond properly to pressure treated ply. |

| I would go with pressure treated plywood. Try to get it close to dry before
covering it with anything, I have heard it takes a full six months of drying
out before anything will bond with it correctly.
Having said that, I used PT to rebuild a set of seats. I used PT
construction adhesive and it worked great and I did not try to dry it out.
If you don't need the strength or can simply go to a larger size of PT, you
could probably forget the fiberglass. Providing of course that you can get
enough screws in it to prevent it from warping.... |
