Just removed the plywood flooring from my boat, and found that the stern end of the ply has dry rot. I cut back to clean timber, but is there a paint or other substance that i can apply to prevent this happening again. the ply seems to absorb moisture through the open fibres on the ends but top and bottom are fine, so i need something that i can apply to prevent moisture entering.

this is flooring from an alloy boat, trhe only timber used is the flooring, the ends are where the water is getting in and rotting the timber.

You have discovered the weakness of ply......unsealed endgrain lets in water and rot soon follows, as rot needs warmth and water to activate it to eat the wood.......
in 30 years of building/repairing boats, I've not yet heard of using laquer in this application..what does work is good old epoxy resin..thinned with Toluene or denatured alcohol, brushed on till the end grain stops soaking it in......do it to all the end grain you can reach, and all the endgrain of the new ply going in.
You can buy WEST resin at most marine supply stores; Git Rot sorta works but I'd spend a few more bucks for the epoxy and catalyst from WEST

I'll agree with yankee, the best thing you can do is seal with epoxy. I'm a fan of West System as well. Keep in mind that epoxy will bond to polyester resins (like most fiberglass hulls) and be much stronger, but poly resin will NOT bond to epoxy. ANY wood on the boat needs to be completely encapulated with fiberglass and resin... by "any" I mean all stringers, floor cores, gunnels, etc... the structural parts. That doesn't apply to teak or mahogany trim, which you should still treat with an oil or varnish.

You could fiberglass it, or at the very least soak it in resin. But the best and permanent way to fix that is to use marine grade plywood. Made just for what you need. It may be hard to find if you are not near a boating community, and its not cheap, but it worth it if you want a fix done right.

Use West system epoxy resin to coat the boards against water damage or dry rot or T88.

may i suggest that you think very careful about what you ask!!!
what are you using for your timber deck??? have you give it a thought re: Laquer! good old marine laquer!! go to your Marina outfit/ repair supplier etc. etc. and also you could also do with waterproof Epoxy compound to seal the gap you created!!

simple. get a can of epoxy resin from your nearest auto parts house. coat whatever is necessary to solve the problem. it's cheap.

Hmmm. I'd apply either a sealer, like Thompson's Water Seal, or i'd fiberglass it.
