Question about sealing wood

[SuzukiChopper]

Hey, I finally got around to purchasing all my wood for my project. Still snow on the ground though and a big drift infront of my boat at the farm so I can't quite start at it yet. I did have a question though about sealing the wood for the flooring.<br /><br />While I was shopping around for this, that and the other thing that I could use in the boat, I came across this sealant. I don't remember the name of it but it's like a paint, except it stays rubbery to expand and contract with the surface it's applied to. They state it's 100% waterproof and works on wood surfaces. It's also quite a bit cheaper than epoxy (about $50.00cdn for a gallon), easier to apply and not as "messy". I was thinking about coating the bottoms and edges of the flooring pieces with this stuff and then using epoxy on the top (going to carpet everything so i want something good for the carpet glue to adhere to). Any ideas of whether or not this is a viable solution for the undersides and edges of the flooring? It would really cut down on how much epoxy I have to order and have shipped in.

Without seeing what you're aiming to use, I can't answer this anymore than anyone else. On general principle, though, I think that you get what you pay for. Be careful with the snake gel. On the other hand, buy a bit, coat a 2x4 with it, and throw it in the snow drift. Check it in a month and see if it's as dry as it started out. Maybe you'll have a new suggestion for all of us.

You not talking about deck treatment?If so,read whats in it.If it has oil in it,by appling it,you will not be able to glass or paint it!

Re: Question about sealing wood

not deck treatment no. It's a paint, like an enamel almost, but supposidly stays rubbery. It kind of reminds me of the type of paint they use on concrete around pools. I think I'll go and get the name of the stuff. I'd try the little quantity thing, but they only sell the 1 gallon jugs

Suzuki, I will assume that this is a standard floor replacement over foam. If so, the accepted method is to seal the plywood with resin. For a floor, I usually use polyester resin ($25US/gal), and some cloth over sun dried, pressure treated 1/2 plywood. First I seal the plywood on the sides and botttom with poly resin, then saturate some cloth with more resin and lay it over the foam (to stick the plywood to the foam better)and stringers, then I screw the plywood to the stringers with ss screws. Finally I cover the plywood(and screws) with 1-2 layers of cloth and saturate with 2-3 coats of poly resin. Now, no water will penetrate the plywood, unless you drill holes in it.

Re: Question about sealing wood

I was going to do that, except using epoxy throughout. I just do not like polyester resin. But once I saw this stuff I thought it would be a great alternative. I'll try and get some information that can be seen on the web.

Re: Question about sealing wood

Suzuki, Epoxy resin will be stronger and much more expensive. However, I do not think you need the strength it provides for this application. I use epoxy for most structural hull repairs (with holes in the hull), and poly for most other things.

Re: Question about sealing wood

I agree. Unfortunately this hull does have holes I have to repair (some made by my own stupidity in drilling holes for mounting seats at the end of last year DOH!), so I have to order in epoxy for that. I'm also replacing the stringer and am adding 2x4 ribs in as well to help strengthen the hull. Going to be using epoxy anyways, and the extra cost of hazardous shipping to Canada for the amount of poly that I'd need is rediculous, not to mention any delays that might happen at the border (no I don't have anywhere local that is abe to sell enough poly to me, only quarts at a time for $25 a shot). I just thought that this sealer would be a good alternative to having to order another gallon of epoxy, and yeah, the strength for the flooring isn't needed. I could probably also use it to seal the parts of the ribs and stringers that aren't covered by epoxy, yet again reducing the cost. I think I have nothing to loose (won't have this boat for more than a few more years anyways), so I'll pick some up, coat a piece of wood and I'll let it sit in a bucket of water for a while and see what happens

Re: Question about sealing wood

I love you glutton! I've been hunting all over for a place in canada that supplied that stuff. I'll be giving them a call on Monday. <br /><br />Still going to look at this paint though and see. The one said it was good for 20 years.

Re: Question about sealing wood

Sounds like you're talking about UGL Drylock or something similar. Might be worth calling them to see what they say about potentially using it for your application.
