So, I've got all my deck down...1/2'' five ply MARINE grade

l_198eb501f2d7479e9d193e0067b3aa86.jpg


I plan on coating it all with a layer of epoxy, then a layer of like 1.5 oz fabric, then another coating of epoxy. Then off white paint with snap in carpet. I've used peanut butter to attach it to the stringers and hull along with counter sunk screws (along with overdrilling into the stringers, filling with epoxy, predrilling again). I'll be using 4'' tape to tab it in too. I've "caulked" it along the edge where it meets the hull with yet more peanut butter.

I will not be installing foam.

My belief is that all must be done to keep water from getting through to the actual wood of the deck and that the stringer's encapsulation must be excellent, and with my work, including 3 layers of 18 oz, I feel it's pretty good.

I've done a lot of reading and searching here and heard various different arguments on coating the deck, both on the top and bottom. I decided to NOT coat the bottom side citing the theory that it can "breath" and i take on a crapload of water, I shouldn't have anything to worry about because rain, boarding water, etc will be kept off of the top. As you can notice though I did coat the edge of the deck where it's cut out for the fuel tank fittings and for the not-pictured 4'' inspection port for the floor in the cabin (porta potti floor).

Might be a little late to post this, but what do you guys usually go with? To me, preventing water from getting in the hull is the most important thing. Pull the bilge plug (don't leave it in, and the boat outside over winter, like the previous owners did :( ...stringers were wet but not like mulch so it was probably okay until then), keep indoors when possible, keep the cover on when possible, don't allow for much leakage, that kind of thing. Then again aside from the "main" part of the bilge, water won't be able to get into any other compartments below the deck.

And aside from being attacked from water from above, the original deck held up okay with no coating on the bottom side

Re: Bottom side of the deck

Nice job F14. I how ever, personally believe in treating ALL sides of the deck wood. Water is a mysterious thing and she has her ways of penetrating. Now if you glass the top completely so no water can get under the deck, then you stand a good chance of having a lasting deck. How ever, if there is any way for the water to get underneath, then there will be problems down the road. Now glassing the top will definitely slow down the deteroration of the deck, and you may not see it come through for quite some time.

IMHO, epoxy it all including the sides and you will have a very rigid TOTALLY weatherproof deck..

I am sorry F14. I just now noticed you have marine grade ply down...You are good to go as they treat it especially for our applications. The glue is waterproof and so is the surface. You are good and protected now as you have done a nice glass job on the top..

I was speaking on a premium exterior non marine grade type of ply...My bad...

Very nice work!!!!

Your work, thus far, looks fantastic.

Re: Bottom side of the deck

I like to coat the wood thoroughly myself, but when you think about it, most of these boats we're redoing these days are 40 or so years old and most weren't very well taken care of and the original wood lasted this long. Anything you do to prolong the life of the wood with even minimal care has got to be better than what was in there from the factory.

I have a few boats with original wood that's survived, with nothing on the back side, and barely anything on the surface as well. They are just kept dry and have been since new. I've also had others far newer, well rotted that were left outside uncovered for 10 or more years.

I did one boat years ago, one of the first boats I had with a plywood sole, I cut out the old rotted wood, I traced the old wood and cut new plywood from what ever I had, probably just CDX sheathing, I painted all sides with several coats, set it in place with 5200, sealed all the edges, and laid down one more super wet coat of deck enamel and sprinkled on some sand. That boat is still in use today, the current owner leaves it in the water, uncovered all season, and only beaches it for the winter. The deck is still solid, still covered in paint. It's been no less than 20 years since I put that wood down in that boat.

thanks for the opinions and encouragement guys. I'll have to take some up to date pix...this is from a few days ago before I epoxy-ed in the plywood in the cabin

I'm currently working on the "boxes" that hold up the cushions and stuff. All will be peanut butter-ed and tabbed in. I would think that the wood in there is fairly important for structural integrity because the stringers don't extend that far forward.
