Thanks for the video, I bought an old sup that needs repairing. this breakdown of repair steps is going to be real helpful.
No problem. There is also an article on my website at AppalachianDIY.com that you can read through also. glad you enjoyed the video👍
Appalachian DIY what type of resin/hardener did you use? Fiberglass resin and hardener doesn't usually mix 2 to 1

great video. I just had Hobbie pedal boards given to me. They look like they were dropped off of a cliff. Hopefully I'll be able to bring them back to life.
Goodness! Well good luck and come back to let me know how you make out
Thanks, great step-by-step and tips. Much appreciated!
Thanks!
You can use foam filler like Q cell to fill space after cutting first, then layer with few layers of glass save yourself some time.
Wow! Thats awesome, didn't know there was a product like that. Thanks. New video perhaps :)
Foam filler! Mix it in your epoxy or poly rez til its thick like paste .
Also its a good Idea to tape the area your working in so you don't over sand.@@appalachiandiy2415
3 years later, I'm sure the crack came back or the patch has fallen off since you stuck it to the gel coat.
You need to sand off the gel coat to get the fiberglass to stick.
It's still going strong. no cracks and no flaking. It is a good idea to "rough up" the area for better adhesion of the resin. thanks for the reply
THANK YOU for doing this.
Chris Browning your welcome! Glad you enjoyed it
Great Tips!
Review Outlaw thanks!
I use JB waterweld epoxy putty to fill holes as it won't eat the foam inside. Coat over the top for a quick and long lasting repair or go all out and fiberglass it. (really depends on the size of the crack or hole)
Great tip! Do you keep it with in case you damage your sup while your out?
@@appalachiandiy2415 Any vessel i'm on I always have a little waterproof satchel or waist pack with JB waterweld, keys etc. Poke a hole in your john boat, kayak, canoe, SUP? Plug it and continue on the day til you can do a more permanent fix. It will last a long time even if you just kneed the putty and stuff it into a hole and leave it at that. if it's a rotomolded kayak, it's a FIX that will allow you to continue on your way but you will have to use heat and do a true repair on that. I Used to carry a mini roll of duct tape for "Oh Sh*t!" moments, waterweld is so much better!
@@bullyakker Nice! I've never used the water weld but have used the original more than I can count
What coating do you apply over the waterweld? Just Paint? Or Paint plus 'hot' coat?
@@peterdawson3690 I like hot coating fiberglass (or similar on my kevlar kayaks) over. Add some dye and brush it on, sand it down and make most damaged areas hide well. On the aluminum John boat? I chipped it out and used regular job weld to repair it (some years after the initial patch and the waterweld was still holding well all on a 2 minute "stuff the hole!" Patch). I sanded then painted the entire vessel with enamel. Can't even see where the 1" round hole was. I just repaired a buddy's SUP using waterweld, fiberglass and then after 80 grit sanding, hot coated with color and I was impressed I could match color so well (it was white, WHITE! LOL) that's a permanent repair that will likely be stronger than that inexpensive styrofoam board with a thin wood laminate and fiberglass over the top. After that repair, he'll be bringing his good boards to me as he knows I can do it and make it look good. I wind up repairing lots of styrofoam SUP's as the fins are only held into the styrofoam with some type of glue. I can drill just into the plastic mounts and stuff waterweld into the holes I put all around the mount then pack it down, sand, sometimes fiberglass cloth and sometimes just a hot coat as the waterweld is waterproof on its own so the decision is more about how much someone wants to spend, and what the craft is worth
Hi Shawn,
Thanks for your video. Have a ding to repair in an old board, so will be putting your method to the test soon! Just wanted to ask about the "Hot Coat". What is it? Just a layer of epoxy spread thinly over the repair area? If so, is it a standard epoxy mix, or diluted somewhat? Thanks again.
Yes, its just a thin layer of epoxy. Just the same stuff you will use for the repair will work. Good Luck!
Nice video! What type of resin do you use?

How can you not sand out the paint first?! the resin will not bond well and peel off after several use
Do you mean sand like I did at 2:35?
Great video man. I damaged my board and was researching how to get it fixed. Question for you ! You look very confident and experienced in this type of work ... but you said its your sisters paddle board . You also have a wetsuit hanging .... so what your story man ? 😁 thank you for the video . Helped alot
I have done auto body repair with fiberglass, First time on a SUP though but same concept. I SCUBA Dive so thats the wet suit. Thanks for the reply!
Thanks for the video. I have a similar, but slightly bigger crack in my board - on a dark green with bamboo veneer board. But one side of the crack is much lower than the other side, so they aren't level. Plus, the crack is on the slant, where the standing deck meets the rest of the deck. Also some of the crack on one side extends to the bamboo veneer. What do you suggest for fixing it, given the sides aren't level and it's on slant? And does the crack in the veneer need to be fixed differently?
Its kind of hard to picture what your describing. You can send a picture to AppalachianDIY@gmail.com so I can better understand how the crack looks. You can fiberglass over your veneer but it's not going to look the best. It may be possible to fix the crack then get some bamboo veneer and hot coat over it to cover what you grind/sand away.
Can you tell me what the products that you use are?
When you see a hot-coat do you mean a clearcoat as a last step , how would make it shine as new?
Thanks
I think a "hot coat" is just a light coat of resin only, no fiberglass.
wardoc77 jeff is right a hit coat is resin with no added fiberglass. It should be shiny if you apply it smooth and dont mess with it to much let it "flow"
Hey hey, i need to fill up the crack.. the epoxy resin wil not eat away the inside of the board ?
(The soft tempex)...
I would test a small amount before filling the entire thing.
Hi , I was wondering if you can send me a link for the last product you used after you used the white paint . Thanks
I just updated the link in the description. Its solarez from amazon
👍
What do I do with big divit where styrofoam is showing?
My board was missing chunks of foam, so i filled it with a light density foam insulation from the hardware store, cut the excces with an exacto knife, Then followed with fiber glass and resin, sanding in-between each step obviously...then spray paint.
is that pargliding gear in the background?
Tom S its SCUBA gear
Thank you!
Absolutely!
