When I did mine I had a piece of plywood with wax paper on one side. I poured one section at a time then put plywood over the top and kneeled on it to prevent the foam from expanding to high. I let any excess bleed over to the next section to be poured. I also had a removable piece of plywood cut to shape with the wax paper where you used the pink foam. It work out great and I didn't need to do any sanding. I wish I had done a video when I did mine but I didn't. I recently pulled the floor up on mine (marine grade plywood) and after 12 years the foam is in perfect shape. Good luck on the boat.
I did the same build 35 years ago. 14 ft. mirrocraft deep fisherman. Gutted interior complete. Installed flat floor,small deck w/built in storage built box across where center seat was w/flip top door on each side (gas and battery). Padded and upholstered top of 54 qt. cooler to set inside of box. 2 pedestal seats and carpeted throughout. All pressure treated 12x4 and plywood construction bout 200 lbs. of wood. A long story short, I researched the flotation of styrofoam and it only floats 50 lbs. per square ft. Glad I didn't have to see if my boat would float because I would be pretty wet!!!
So once you cut into it water will enter foam maybe next time pour foam and lay a piece of plywood over it with plastic underneath. it will come out perfectly level when you lift wood plastic will stay an barrier will no be compromised. Saves megga time..
Another way to do this (that would have given you a perfect glossy top finish that wouldn’t need paint) would be a sheet of ply + poly sheet with a hole in the Center. Pour through the hole and the excess will come out the same hole. Works perfectly.
I do wish I spent a little more time to research and do the foam better, hopefully it lasts a long time the way I did it though😬 I guess it’ll be a learning lesson if not.
I recently pick up Jon boat plans for something like your doing it has 3 seats and just need space for myself and maybe my dog so I look forward to seeing how yours goes Thankyou
Does it state on the bottle how much to mix in order to fill a certain size space, (volume)? BTW, good info in your videos. I am doing the same type of restoration on a 1981 Starcraft Mariner 18 center console. Should start the floatation install next week....
I don’t believe there was a specific amount of liquid / volume of foam ratio, if you order more foam than you need you could definitely do some test runs in a box or something? Otherwise it’s really just trial and error, it was in my case at least lol
The pink foam board and spray foam will disintegrate if it comes in contact with gasoline. It is not rated or approved material for this use. It worked as a temporary stop for your foam pour, but isn’t the right material to use. It would be better to block those gaps with other material that can be removed later or an approved foam insulation.
You said you want the foam to be as dense as possible. Not really. You want the foam to be less dense than water. 2lb density foam will give the greatest amount of buoyancy as it has more air entrained in it. 90 percent of the reason you put foam in the boat is safety. if you take on a rogue wave and/or can't pump water out faster than the boat is sinking the foam will provide the bouyancy to keep it afloat with water in the boat and at the very least slow it down from sinking completely. The other 10 percent reason you pour foam is for lightweight structural support. thats where some people use 4lb or 6lb density foam instead of the commonly used 2lb foam. it is more dense and thus stronger and more rigid. 👍
Appreciate the information on the foam.Am in the process of redoing a bass boat deck and transom and wasn't sure where to get the foam or what to use. Thanks
I bought a boat just like that one this summer it is a 1969. It had trees growing in it I watched other guys on youtube and thay put the floor on and drilled holes in it and poured the foam in. I like your way better Thanks for the video
Someone said when you cut into the foam, it’s not sealed anymore and could take water. I’ve never experienced it, but I coated my foam with an oil based paint to help reject water from entering the foam cells. Thanks for watching and good luck with your boat build!
@ryanbrady752 I’m not sure what they’re considered, they don’t seem like a deep V but I’m not sure I’d call them a mod-v like what people use for duck boats.
@@myparadiseonbantayanisland9030 Good point… I actually was asking US composites this week about shrinkage, and they said if your mix isn’t 50/50, it CAN shrink after a week or so. That would for sure cause problems. On the other hand, it’s very sticky, so if you cleaned the inside of the boat fairly well (get rid of grease etc.) it should be OK, at least in terms of water between the foam and the aluminum.
Thank you for the tips. Vibrater saw and pour more then less good to know. Side note. The surrounding look. Very western washington.. I live in east Kent.
Some other people dropped good tips in the comments I wish I followed, some said to put plywood on top of the cell so you don’t have to cut and it’ll stay a sealed cell that way as well instead of opening the cell when I cut it
@savagesenseoutdoors there is videos out there that show that working perfectly. Then the disaster of it not. From what I have gathered as the foam expands it hardens, bottom still liquid top slightly firm pressure from below the foam expanded too fast and lifted the deck. About 3 inches. That was a fiberglass boat..if your still with me. My boat is built like yours. Use scrap plywood that covers a few compartments and cut a 2 inch wide 2 foot long hole width wize. Then put oil or plastic wrap on the underneath side of the plywood so foam don't stick clamp inplace pour a few, lift and continue. Thoughts?
I'm following your build w my 16' MirroCraft Deep Fisherman project. i was leary of pour foam but you kind of de-mystified it. I can see some advantages for structural support. I was going to just stack pink foam. Keep the vids coming!
I considered doing pink foam as well, I think it’d work just fine for the water displacement/buoyancy aspect but I decided to go with the pour foam for the extra structure like you said and to help keep the boat as rigid as possible. Thanks for following along!
I’ve learned so much from you guys there’s not really anything I could add to it everything I’m learning is that is above board I’m a master carpenter. There may be some things. I’ll add when I put the beatbox in and things of that nature that make it more accommodating for me, but I also appreciate the free long sleeve shirt.
Just wish I’ve gotten more done on it last summer, I do wish I brought the subfloor all the way to the nose though. That’d make it easier when I get to framing the front deck
@@savagesenseoutdoors ya I started my restoration last September, told the wife I’d be done by the new year … that was a lie lol I have a 21’ StarCraft holiday so it was a cuddy cabin time bow. I’ll frame all the way to front. Framing never really crossed my mind until I came across your videos. Do you wish you’d done wood floor vs aluminum? I’m leaning towards since I’ll be bolting seats down along w vinyl flooring
I’d only wish I did plywood for the cost savings and it’d be considerably easier I think. But I’m hoping that the weight and longevity of the aluminum makes it worth it in the long run
I used all of it. A few pods got overfilled, I think I gave some good pointers in the video about what I would’ve done differently if I remember correct. You may have a little leftover if you take those tips. Otherwise I filled my low spots with spray foam and it seemed to work good.
@@irbinortiz5843 that’s awesome man! This is my first boat build as well and I’ve learned a ton from watching TBNation. I’m excited for Spring season so I can get back to working on the boat.

Awesome! I’ve got footage of framing my rear deck I’ll be editing up soon
the foam is going well and to see it on the water
Doing my 14' aluminum now. Putting the framing in.

Can water get between the foam and the aluminum? If it stays wet there corrision may be an issue.

Hi the video is so nice and helpful! I also have bass boat and would like to foam it. What is material and what brand of the pouring foam?
I think I showed it in video, but it is Totalboat expanding foam. Got it from Amazon
Looking very nice and light weight,in the process of getting my StarCraft 16ft salvage also looking for ideas 💡
Awesome! I bet your boat is pretty similar to mine
love the video we are going to use pour foam also
Yay, a free shirt 😂
You’re late to the party. And who doesn’t like a free shirt?
With aluminium hulls you want water to freely drain. The best solution here is to fill the compartments with empty plastic milk bottles.

Thanks man! Hope it goes well for you. I’ll have a subfloor decking video posted sometime this week👍🏻
Will the foam help you draft less and run skinnier or just help you not sink?
Great video the boats looking good

It’s total boat flotation foam, I bought it off Amazon. I think I went with the lightest pound per sq ft compound.
Awesome boat
Thank ya sir! Hope to get some more work done on it soon
Got the same Boat same Color but it is 20' put a new Transom in and now the Floor Total suck Nice Video
chain locker ,fuel tank water tank in bow put small deck on bow ,3ft by whatever side to side,
I’d like to see a full deck on the front
Yes sir! I’m currently excavating for a 30x30’ on my property but the next step for the boat is framing the front deck!
Is the foam waterproof
Foam gets waterlogged after time if you never pull your drain and let it sit in water but it is meant to be waterproof

How many gallons of foam did you use?
I believe I only bought one kit and it was barely enough for what you saw, one gallon of foam and one gallon activator I think. They mix 50/50
They came in a kit on Amazon
why would you put oil based paint on a boat
To try and keep water from entering the foam cell
I like the foam
Thanks! It worked well👍🏻
Everything on amazon is 4 1/2 stars , even junk
