Joe, I'm going to do my best here to share what I did with 2 part foam and fiberglass, but it is hard to explain... Imagine a boat like a Boston Whaler with seats and such molded into the upper fiberglass section. Now imagine that the foam poured between the hull and upper seat/decks section did not fill all of the available space, but that space (those spaces) were intended to be closed up. This describes the boat I am restoring (it is an inboard power version of a Skipper 20 sailboat) The previous owner cut holes in the vertical seat walls to create storage spaces. The "inside bottoms" of these sea areas was the inside of the hull. The seat/deck section had gaps/spaces that allowed warer to down into the deck/hull gaps. The water that got into those holes now had nowhere to go. Over time, this waterlogged the trapped foam. With some strategic draining and drying (over months) I got to a point where I could start fixing things. I did not want to lose the storage, but it had to be done differently. I cut new access lids into the seat tops. I fiberglassed the holes in the vertical sections. I poured new/additional foam into the storage areas so it could fill the gaps. I shaped the cured foam (miserable job) so the floor of the storage areas was higher than the deck/sole outside the storage area. My objective was to then glass over the foam to create these storage areas. I would later add drain holes through the side wall so water could drain onto the sole and eventually to the proper bilge. The issue was that the foam expanded and cured in such a way that the edges and corners had deep gaps. I used deep pour epoxy to fill those areas and close up the forest the shaped foam. I was then able to glass the floors of the storage areas. Anyhow, I thought this was a worth sharing.

[@FishBumpTV]

Hey Joe, thank you very much for sharing your knowledge. I would like to ask you about flanges. I’m a saddle maker in Australia. I’m starting to explore making my saddle trees with these pour foam and fiber glass. I started working on my plug once that done I will need to make flanges to be able to bolt the mould together to then pour the foam and will expand it the shape of my saddle tree. Do you have any information already or would you be willing to share some of your techniques about making flanges. Please and thank you so much your knowledge so far has helped me so much I will for forever great full

[@FishBumpTV]

Interesting line of work that you are involved in! Some molds are very simple, and others are quite complex. I really don't know a lot about saddle making, so I'm a little in the dark on this one. I do have some videos back in our 29ft boat build series of videos that show me building the console and seat base for our 29. And of course, our hardtop mold building series. Maybe the answer is in there. If not, I will try to do some research. Maybe you can comment back after watching and let me know. I will also be opening up some of our patreon spots very soon. That allows me to consult directly with you via phone calls and emails. I wish you the very best with your project, and thanks for watching all of the way from Australia 🇦🇺!

[@gunnarfernqvist4896]

Great video as always and an interesting experiment! I have a followup for you, how would it be to fiberglass over the easily available boards with different resins. How would it react and more interesting, how easily would it delaminate? Maybe, what will the sandwich strength be?

[@mehrdadmorabbi6743]

Thanks Joe, I really enjoyed this one! My camper project is on hold until I finish my subframe, but I’m trying to soak up all the information I can on the use of foam and fiberglass for building structural components. One question, I’ve noticed most builders follow foam with CSM, is that for structural reason or aesthetics? I build a 2’x2’ sample 2” thick using 2 layers of 1720 and 6# polyurethane foam and it appears to be fine. I used a router sled to flatten the side that wasn’t in the mold and short of using more resin on the first layer of 1720 I didn’t notice any issues. Should I plan on using CSM before 1720? I don’t care about the way it looks cause it will be on the inside of the camper and will be covered with some form of paneling.

[@FishBumpTV]

I'm glad you are enjoying the videos! Csm seems to bond very well on the initial coat, and I do think that it has a nice look when finishing out. Just remember that csm doesn't behave with epoxy resin like it does with polyester and vinyl ester resins. I hope this helps, and thanks for watching

[@DavidGierke-nl1dl]

I have an application where it would be advantageous to remove the foam core after an outer (multiple layer) fiberglass shell has been constructed around it-for a one-off, light weight structure. Is there a chemical (acetone perhaps?) that might be used to dissolve the foam after the construction is complete? Thanks for for your professional, well-done presentations. I've been glued to my computer screen ever since I discovered your channel two weeks ago. A suggestion for a future topic: carbon fiber and kevlar in place of fiberglass. I'm a velomobile enthusiast (recumbent, tricycle, pedal and electric-motor-powered transportation vehicles that are shrouded in an aerodynamic shell -thus my primary interest in your work.

[@FishBumpTV]

You could, in theory, use epoxy resin over xps type foam or Styrofoam. Then use a solvent like acetone to dissolve the foam. I think that using sandpaper, a scraper, or a wire wheel would be the best way to remove the bulk of the foam materials first. A good shop vacuum would really help keep airborne particles down, or a vacuum assisted sander like the festool that we are currently using in the shop. Some small-scale experimentation on your side, before you tackle the actual part that you want to build, is always a good idea. I hope this helps and thanks for watching and commenting!

[@HikerBikerMoter]

Those three structural foams to the left are perfect if your looking to sandwich it between two layers of S-fiberglass/epoxy for a DIY 24 foot boat to circumnavigate the globe. Great way too add thickness to your thin hull and presumably the foam also has good? heat insulation properties too...

[@FishBumpTV]

Agreed! Thanks for watching and commenting!

[@bkrmar]

Hi Captain Joe How about PVC foam board? I plan to use it as flooring for the boat console. The plan is to laminate it with poly resin and csm. What is your opinion ok this method?

[@FishBumpTV]

Sure, PVC foam board that is designed for structural marine applications can be a great material. Just do plenty of research, and maybe some testing before you start your project. I hope this helps and thanks for watching!

Can you make a plug with the foam by pouring into or over a object with some plastic layed down so the foam won't stick?

Did you use some sort of release agent on that container? I've used that pour foam before and it sticks to EVERYTHING. I'm planning on fiberglassing my bathroom subfloor so I have been watching your videos to prepare. You make it seem easy and almost relaxing but i know that anytime i work with something that has a limited working time i am stressed out, i always forget something in the prep phase, and i wind up with material everywhere.

[@FishBumpTV]

No, I didn't use any kind of release agent. The little clear bins came straight from Lowes. I always try to lay everything out beforehand and mentally run through every step of the job. Having a nice work table on wheels that you can position near your work is also a big help. Having grown up using these materials my whole life also gives me a high comfort level working with these materials. That will happen for you all as well. The more you work with it, the easier it will get for you. I hope this helps, and thanks for watching!

[@chrisevans2645]

@@FishBumpTV I try to think of everything but I always forget something. Fiberglass is definitely something that I want to add to my skill set but I don't plan on doing enough to get to your level. I'm more in the jack of all trades category. While I wish I could be a master of all trades I think the best I can hope for is competency in each. If it weren't for people like you, thunderhead289, essential craftsman, mrpete222, adept ape, abom79, stud pack, and many more it just wouldn't be possible. Books can only go so far and few tradesmen would ever bother trying to pass on their knowledge that way. While the printing press was a huge leap forward the Internet allows average people to share their knowledge. Of course you have to filter out the noise that comes with that but how else can you learn so much so fast? People may spend their entire career in one trade, watch a few KZbin videos, and learn something they never knew.

I'm looking to an alternative to 'stitch and glue' build up for a small sailing dinghy. I was wonder if some form of fiberglass, foam and resin might have some advantages...perhaps 1. Cheaper, 2. Easier to build 3. More Floatation 4. Lighter. Any thoughts if this is a good idea? Or, should I just stick with marine plywood and 'stitch and glue'? Thanks

[@ninehundreddollarluxuryyac5958]

Nidacore honeycomb core is about the cheapest core material available. It weighs almost nothing and is super strong after fiberglass is laid over it. You can lay one layer of chapped strand or surfboard cloth over it and still bend it into shape. Tape the seams instead of stitch, with big gaps between tape. Fill the gaps with thickened resin to hold it together, then remove the tape and glue the gaps with the same thickened resin and fiberglass a bunch of layers over the completed shape.

[@FishBumpTV]

Sounds interesting! I have built several stitch and glue style skiffs before, and it is pretty hard to beat plywood for strength and cost. I think coosa board could be good, but it costs considerably more. Some testing on your end could be a good idea though. Hope this helps and I appreciate you watching!

My dad built boats with marine grade Douglas fir plywood back in the late 50’s to early 60’s. He covered the bottom and deck with fiberglass. Many of those boats are still around.

My dad used to have a company making Polyurethane kit (not yacht based). When he was sorting the mixture out he would stick enough into a plant pot type vase. There would be enough that it would expand and just overflow enough to make a mushroom shape. Quick spray over that with white for the "stalk" and red paint over the top with a bunch of white spay dots.......sold them to the local garden centre for more than he'd have got for throwing the test pieces in the bin 😆 My concern is how Polyurethane these days handles any "sweat". Although it is water proof it can rot with any water ingress. Too many people insulate their homes with Polyurethane and it's just going to cause issues. Hopefully this Polyurethane doesn't have those issues (I'm 30yrs out of date when it comes to Polyurethane)

The foam comes in spray cans too. You can use masking tape to close off areas and spray foam in through a hole in the tape to fill in an void or hollow area. It takes almost nothing to hold a bunch of foam in place to build up an area, then sand back to the shape you want once its hard.

If you paint XPS, resins will not distort.

[@daiquiri.]

But there will be no adhesion between the resin and the foam - the resin will stick to the paint and the paint to the foam, so the adhesion of the paint will be the weakest link in the chain, not very ideal..
