I’ve got a 5’4" Bryne shortboard I’m trying to fix up for my cousin who just turned 8. Should be perfect for her. But unfortunately when I got it there was a massive delam on it. We’re talking about 3 feet long and on one side of the board. I stripped off the glass and reglassed most of it, but there’s one especially deep section were the foam had deteriorated so much it was soft.
Since where I live I can’t get a blank or even a scrap of foam, would it be feasible to make a plug for the hole using EPS and then glassing with epoxy?
And if that works I’d like to do deck patch with a resin swirl over it to hide the damage and keep her from dinging it any worse than I did. But will I have to use epoxy with to lam it or will poly over a small patch of epoxy work? I had read something about that in the archives (flex characteristics and all), but there seemed to be a lot of contradicting opinions.
Sure, attach it with GorillaGlue, Elmers (let set 4 daze), epoxy resin and microballon mix, TackyGlue, or any other adhesive that is stronger than the EPS.
Use epoxy resin for the whole job near the EPS, to be safe. Hope your resin is UV resistant and doesn’t change color.
Save you poly for other dings. Use epoxy resin anywhere near the EPS.
My advice: try first to get a sheet of polyurethane (the yellow one, used in insulation and by aeromodelists), so you will later be able to use poly resin instead of mixing epoxy and poly in the same board. It’s not easy to find polyurethane sheets, but spend some days trying. I found it inside pre-built walls for barracks.
If you’re in US or UK, you can buy easily (I hope I could do it here in Spain) a “2-part urethene foam kit”. It’s a kit of 2 small cans, one polyol and one isocianate. You mix them 1/1 ratio, pour the mix quiclky in the “foam valley” and let it expand. After some hours just sand it flush to deck and glass over it.
Other advice: You can use cloth inlay to make-up your restoration. Just fill/expand/sand flush/lam cloth/trim/lam glass/hotcoat.
