I am shocked at how well this came out. Check out this video where I use BetterBoat's Epoxy to seal the plywood used to deck out the Jon Boat Build. Big thanks to Better Boat for sending over the epoxy for this build: betterboat.com/ In this video, I go over the process of sealing wood with epoxy as part of the Jon boat build. Epoxy is a durable material that is perfect for protecting wood from water damage and rot. I'll show you how to properly prepare the wood surface, mix and apply the epoxy, and finish the project.

So what do you think, will it keep the water out?
your voice is calming 😌
Thanks for this video. I am considering this for a plywood camper I want to build. I'm in the research stage now. I figure if it's good enough for a boat, it should be good enough for a camper. I wonder if you can paint over it.
For sure! I've painted it no problem. Great idea
Did your foam roller last for the entire first coat or did you have to use multiple rollers? How long did it take to dry? And how long did the rollers stay usable
@@itidbits7205 I used a couple rollers, once the epoxy starts to thicken they start to fail so it's best to work with small quantities.
I want to build a casting deck for my jon boat. Would you use the epoxy or resin next time?
I worked for a polyester resin manufacturer for 15 years. Most of my customers were boat builders. (Ranger, Cobalt, Bayliner, Skeeter) At the time all the stringers, decks, and transom’s were made of wood, encapsulated in resin and chopped strand. Some of the hulls and transom’s woven roving. (Kevlar was just starting to by used and Ranger built a company that made 2x4’s out of what was call “pultruded resin”. Basically a block of resin molded into whatever length, thickness and width needed.
Long story story, polyester and epoxy resins will waterproof and strengthen the hell out of plywood and 2x4’s. (I’m building a casting deck fore and aft on a Gheenoe. Using polyester resin on the 1/2” plywood and covering the platform with “Glasliner” board. (See Home Depot) It’s a pebbled anti slip surface.(Fiberglass Reinforced Plastic) You see it a lot in gas station bathrooms. Very durable, high UV protection, easy to clean. (What I don’t know is, how it best bonds to a sheet of plywood that’s been treated with polyester resin….)
Nice video, Thanks for sharing! So do you think this stuff works better than the tried and true fiberglass resin? I'm building a new transom for my crestliner and just wanted to get your opinion on hardness and strength vs the fiberglass resin. Thanks again!
In my opinion, both produce a hard waterproof shell. Resin is looser and a bit easier to apply but has a very strong smell and more expensive. Epoxy has always been a great wood sealer as well. I will say that the epoxy shell is much thicker on the surface so if you're working with tight tolerances you'd need to keep an eye on that.
Love the video very helpful. How long after the first coat before you did the second coat. And did you wait 24 hours to do the other side. Thanks
I did one coat on each side, I waited about 24 hours before doing the other side. Long enough for the one side to stop being sticky
@@mvboutdoors so you gave one coat to both sides of the panel and no second coat.
@@andrewrodriguez6345 that's correct, I did a second coat on the sides but the top and bottom coats were very thick so I didn't see the need for another.
Do you recommend cutting out the hatch holes before the epoxy or would be okay to cut out the hatch holes later?
If you cut out after epoxy you'll need to seal where you cut or it will be extremely susceptible to water damage.
Which one was cheaper overall? This or the bondo resin?
Would 1 order of the gallon epoxy cover plywood that would cover an entire 1648 jon boat?
I'm not sure what is cheaper per Oz or coverage. The 2lb kit was way more epoxy than I needed for the one boat, I think 1 gallon would get you pretty far depending on what you were doing with it.
I like it! So why are table top epoxy generally cheaper? Do you think they would adhere together? I’m building a transom with epoxy so I need something that holds together and will have great strength for the motor
Are you casting a transom out of epoxy or sealing wood?
@@mvboutdoors I’m layering 2 inches of plywood and sealing with epoxy and hoping I can seal each layer and have them stick to each other
@@Nobadcasts It would definitely bond together, the instructions say to added second layers around the 24hr mark so you could plan it out where you coat each piece and bind them at the end.
@@mvboutdoors thank you!
People ask what's happening, I tell them confidently MVBoutdoors is happening! in order to use the BB epoxy resin, do you have to have a scale? Thx again!
Haha, my man. You can mix based on weight or volume, I prefer weight because its easy to mix smaller quantities. This is the one I use: amzn.to/3xGWNzg
I’ve been to Lowe’s, Menards, and looked at Home Depot online for epoxy I couldn’t find, of course Amazon. I do live in Kansas
Yeah I ordered it online, Lowes has epoxy but im not sure if they have it in larger quantities.

How do you glue carpet on? Contact cement or some thing you special order, thx? Also went to academy, nuthin
HD has PC rot Terminator in large gallons. I think it's the same thing?
Been reading epoxy can be cut up to 20% acetone for thinning and penetrating also use a slow hardener for more penetration a cheaper than expensive penetrating epoxy
That would have been a great idea, I would have liked to try that.
Yep,it is waterproof sunroof too
I am wanting to paint me deck what is your recommendation for that
I have not painted any decks personally so I do not have a recommendation based from experience. I would make sure that whichever you choose it has some non-slip properties to it!
Can I now use oil paint on it & the paint won't strip off easily?
Yes, make sure to clean and prep the epoxy first though!
Yep use latex paint,acrylic paint or urethane water based
I am using 11/32 ACX plywood. Home depot didn't have RTD. The temperature where I live will be triple digits probably for at least 30 days straight. I don't care what the floor looks like in that it will be covered . I just want plywood to be waterproof. I will get everything ready and carefully mix it the 2 part resin like the MFG's directives. is this OK? Please say yes
Oh yeah, if you seal that up it will be great -- that's better quality than the stuff I normally use.
Did you put 2 coats of epoxy?
I did two coats on the side that would be facing out and I did one coat on the other side
@@mvboutdoors Thanks. This is my first time working with epoxy. Nice work!
@@keysailfisher it works really well for ceiling wood, I was very happy with it
Just keep an eye on the actual plywood you are using. Plywoods are vastly different in price and quality. Do your research on some woodworking channels. You'll be amazed. Sometimes it doesn't matter, but in some applications it does. I've had cheap plywood delaminate, found ply voids, and even plywood that has wildly different moisture content. The substrate is equally as important at the coating! Keep up the good work and progress!!!
Great tips! I use exterior grade ply so the adhesive used to bind the layers is water resistant to avoid any delamination. It's true you do not want to use bottom barrel plywood.
I’m low low tech, is there something ekes besides boat epoxy which has to mixed just right, is useless after 15 minutes, and is expensive, like some kind of satin paint
Yes, any oil based paint will provide some waterproofing. I like the rustoelum enamel.
@@mvboutdoors I’m not up to the advice on epoxy, aluminum, etc and “doing it right” if “doing it right” is going to take 5x the time and expense of just putting a new deck on after if it rots.
With this Epoxy, does it seem to make the plywood stiffer?? Maybe we can use a slightly thinner plywood & make up some stiffness with this?? What ya think??
Slightly, but if used for a floor I would still go a little thicker but for side panels or something not load bearing for sure.
fiberglass resin? You mean Polyester resin?
Good review, thank you
Glad it was helpful!
The Instructions Before Using This Product tell you to “Work in a clean, dust-free, dry environment with an air temperature between 70°F and 85°F.” “Air temperature must be above 70°F in order for Epoxy to cure.” Nothing is messier than epoxy that doesn’t cure properly.
I would suggest looking at Marine grades of plywood for your boat projects. Local to me, The Plywood Company, Fort Worth, TX, carries
FIR - AB - 1/4" MARINE GRADE PLYWOOD, 4/8, Full Thickness, 7 Plies, at $104 per sheet
FIR - AB - 1/2" MARINE GRADE PLYWOOD, 4/8, Full Thickness, 7 Plies, at $137 per sheet
FIR - AB - 3/4" MARINE GRADE PLYWOOD, 4/8, Full Thickness, 7 Plies, at $152 per sheet
Thank you for the info!
