Thank you so much for taking the time to make this video. I've watched it like 10 times now and I learn something new every time. Time to find some PU foam.
You're the first one I've seen repair one of these boards. I have several in disrepair and this is great information. I'd love to see more of these, most especially if you could work on some of the handles. I have always been confused as to how they are attached and how they are repaired. Keep up the good work, cheers.
I uploaded a video recently of a full respray of one of these. I needed to re attatch the handles at the end and honestly, it was such a pain in the ass I left that process out of the video 😆 I'll have a scrounge through the footage and see if I can piece something together for you
I really like that you use foam for your repairs. I’ve been picking up scraps of PU at a local shop so I have plenty if I have to fix mine or a friend’s board. I just started trying out expanding PU for some fixes and haven’t quite mastered it yet. Glad to see someone else going that route! Now if I could only find them in white, it would be awesome.
Good man, great to hear! Yea, the colour is the biggest downside for sure. It must be possible to source white stuff as they pour blanks out of it. Wil definately hunt some down at some point!
Thank you so much for making this video. I bought a 10’2” NSP used from a surf school. You could imagine the wear. But I got a real good price. I could make the right repairs due to this video. Thank you and I did subscribe.
can you use the expandable foam that comes in a pressure can. l know there is a can that puts out a cheap foam and a can that is more expensive and it's more like a surfboard foam. l do like the fact that you mixed the runny and you called it U P foam, can you get thyat on e bay. l like you video as you exsplan is in simple terms. thanks Keith
Question, why wouldn't you laminate over your 'fill coat' of resin + bubbles? Right after it gone tacky. Doable but on these jobs just to big or it to properly work?
Quite often on jobs of this size, once that filler coat has cured you'll find it can have some airbubbles in it or worse yet, has shrunk back. Often times that will mean it requires another skim coat before lamination. With all that in mind, I find it easier and get more peace of mind to just leave it overnight and let it set itself up how it likes
Could you give the link to the type of foam you are using please. You say you're mixing it, but all I can find is foam that comes out of cans like a spray can. Thanks for your help. Two part mix for foam ???
I totally thought you just used great stuff crack sealer from the hardware store. I don't know if they have that in Australia but we use it to fill cracks in window frames and drywall. It looks the same. I wonder if it would work.
Don't use that, very low density and full of air because of the way it leaves it canister. This foam is a much higher density and quality than builders foam for window jams
Very similar construction for the two for sure! Some of those mass produced wind surfers are done in a "surftech" construction so can be a lot stronger than these clubby boards
Following your channel for quite a time. Interessting how you show us the view from a professional, thanks for that. would you mind naming your specific product expanding pu foam? Greetings from switzerland, Ricky
I cant really name it other than expanding PU foam. It's not a product that is branded or sold whole sale, it just comes from a PU manufacturer. I can give you the hint if you're struggling to find it to look at taxidermy supplies as they use the 56kg foam to fill animals with

hi, thanks for the video! what would you recommend to use for a PU foam, 4 lb/ft³ density (14x expansion) is enough? which one do you use?
11 місяців тому
so silly of me, i just watched your other video. the options for me are either 48kg/m3 or 64kg/m3 versions -- i'm slightly worried that the lighter material might not be enough for parts that have to be load bearing, like the footpad etc. what's your take on this? might 48kg/m3 work?
Gday mate, So I generally do repairs with a 36kg foam which is pretty much bang on to a PU blank you'd buy to shape. I use 64kg foam for really sever dings like large delams or snaps but that's pretty rare. The strength against impact should really be coming from your glass not the foam, the foam is acting more as a support for your glass rather than a structural component. For comparison, an EPS sup or surfboard is maximum 28kgs so all the options you've listed are far stronger than any EPS board you'd buy, at least as far as foam is concerned
Just dinged my week old Torq epoxy surfboard, attempted to do a solarez repair, but started sanding and these little holes are showing up, thinking they are air bubbles, Any advice on how to get rid of them, cheers.
Howzit Ian? Guessing the pin holes are appearing in your solar rez and not the original class surrounding the ding? If that's the case then give it another rough sand and using a squeegee, credit card or whatever you're spreading resin with and reapply another really tight coat of your solar rez over top. Load it up thick and then keep wiping and applying your resin really hard to jam it into the holes. You can do this step a couple of times if that's what it takes to fill them all 🤙
Thanks great video. What pu foam do u use. I have a snapped eps tolhurst with no timber stringer. Have repaired pu snaps and creases but never one of the tolhurst mal. ???????
I have a video dedicated to this foam so search that out. The foam is compatible with EPS so it may come in handy with your repair. Epoxy repairs are all much the same, regardless of the "tech" in the initial construction. If it's EPS and epoxy, that's all that really matters when it come to repair technique. 🤙
@@smallkinedings so generally any 2 part mix pu foam should be ok,? like this..Poliu-foam, Polyurethane foam Compound A and B Multiple Uses Presentation 1/2 Kg. 250 grs. Compound A and 250 grs. Compound sorry I'm trying to source in Mexico currently. thanks for your input as I'm not sure specifically what to look for.
@@rainham1 hey hey, so the foam used on this job was a 56kg so 1/2kg is going to be way to soft. I wouldn't go for anything less than 30kg and nothing over 62kg. 56kg is the ideal and matches PU foam the closest
@@rainham1 gday bud, so ideally you'd find a 3lb but if you can't find that I'd got with the harder of your 2 options. By the time you sand it, it will be a little softer than advertised. I'll leave this link for you which converts kg/m3 to lb/ft3. Just for reference I most commonly use 56kg/m3 and sometimes 64kg from really big jobs like SUP snaps www.convertunits.com/from/kg/m3/to/lb/ft3
So from the little I know, the way they measure foam density is either A. The weight of one cubic meter of the material which comes out in kilograms, or; B The weight of one cubic foot which comes out in pounds. So, the 56kg density foam I use here would be 3.something LBs. A 6lb foam would then come to about 96kg which is insanely dense, I actually can't imagine a foam that hard. The hardest foam I use is 64kg which = 3.99lb so I would say that 6LB would be way to hard for surfboard repair purposes.

@@johngibson3952 no worries man. Sorry, slight correction, I've just edited in the previous comment. I used 56kg foam in this video, not 36 which is what I originally wrote!
I have a question, here in germany everyone say work with epoxy ... PU will eat your Board, can you link your PU Foam that i could try it like you? Greetings from Germany
Gutentag! Pu resin will eat your eps foam. If i poured only the foam liquids, unmixed over eps, it would probably melt too. Once the liquids are mixed together though, it's a matter of seconds before it expands and hardens so, there isn't enough time for it to damage the eps. Any two-part expanding pu will be fine. Mix until it begins to expand then pour it.
A little bit more work with the foam but the use is more for structural integrity when surfing. If I were just painting an art piece I’d probably just fill it with resin too 🤙
Thank you so much for taking the time to make this video. I've watched it like 10 times now and I learn something new every time. Time to find some PU foam.
Unreal, so glad it's helpful!!

Looks good! Feel better soon!
Congrats, man! Amazing job!
Wow, I always thought that PU would eat the EPS! New to me!
Me too
I would have as well, always worth doing tests on things like this just to be sure. This one paid off big tike in the long run
You use the same paint I use to use. Nice work.
It's good shit!

I have a specific video on the foams but short answer is no. Foams from a can lack density and are full of air, not the ideal product for surfboards

So.. how much would you charge for that repair? If you don’t mind me asking. In the UK 80-150 pounds
Yea, pretty much the same in NZD. This one was likely around 200 to 300 mark.
would a can of spray expanding pu foam work? ..the type for insulation etc
Generally that spray foam is too soft, crumbly and porous for surfboard repairs

@@floti99 pleasure, let me know for sure how you go!
I didn’t think of using the foam to fill in the dings on the surfboard I’m prepping to art/paint. I used resin so now it will be a messy sanding.
A little bit more work with the foam but the use is more for structural integrity when surfing. If I were just painting an art piece I’d probably just fill it with resin too 🤙
eeee just slap some duct tape on it and it is ready for paint :)
That board’s “foam” isca real shit material
EPS is possibly the worst material anyone could ever make any kind of surfcraft out of. I'll never understand...
