Repairing a Ripped Seam on an Inflatable SUP
HTML-код
- Опубликовано: 16 апр 2020
- I repair a huge 16-20" rip in the seam on my Boardworks Verve inflatable Ppaddleboard. I can't believe it actually worked! Since the repair I've used the board on both flatware and whitewater and it's holding up just fine.
Here is what you will need:
- MKE or Acetone to clean and remove old glue
- Sand paper to rough up the surfaces
- Vaccum
- Isopropyl alcohol to clean surfaces
- HH-66 Vinyl Cement
- Wood piece to clamp with (may require shaping)
- Clamps to keep in together (recommend test fitting it dry)
- Rubber gloves
- Safety goggles
HH-66 should sit for 2-5 minutes before you clamp the sides together. It dries in 3-5 minutes and will reach full strength in 24hrs. Pay extra attention to cleanup and gluing at the edges of the repair.

For anyone attempting repair, LET THE GLUE SIT. It's gotta get tacky. I have been trying to patch a hyplaon sup/boat and it's been a huge pain. But the best results have been with very detailed prep as shown in the video, and waiting for the glue to get tacky and dry a bit before clamping. I applied it too thicc and wet and it didn't dry.
sit how long?
Helpful, I ordered some HH66 glue and thinner to give this a shot after a local shop told me my board is “unrepairable.” It’s a Body Glove SUP and while the board is awesome, the factory glue job was total trash. So, a lot of cleanup at various places but I think it’s possible.
Awesome DIY tutorial. Thanks!
Thanks for making this video! This is a tremendous help!
Nice job dude, going to add some of that HH-66 cement to my kit indeed
Thank you! This was super helpful!
You are welcome - I am glad it was useful. The repair is still holding.
Thank you, I’m fixing my daughters birthday present that has sat unused after a mysterious hole appeared after loaning it to the neighbor. You are a life saver!
Awesome! Have fun!
Thank you, this was very helpful
Helpful video. I have a similar blowout on my Red Paddle board so I will try this fix. Thanks!
How did it go?
Cool Video!
Acetone can attack certain types of plastics and paints. It will easily dissolve styrofoam for example. Quite fun to watch. It will also discolor acrylic glass and make it milky and make it crack. It can be used as a solvent and as a stripper for some lacquers but in this case it's main function is to degrease the surface to be glued. Grease is one of the nemesis of glue. The sandpaper is used to roughen up the material and give the glue even more surface to bond to.
While not being exactly the same scuba dry suit neck and wrist seals are fixed in a very similar way. Remove old seal, remove old glue, scuff up drysuit and seal, degrease drysuit and seal, apply multiple layer of glue then press together and let it rest.
Isopropanol is also a good degreaser but it usually does not attack plastics. I feel that acetone does a better job at degreasing in comparison to isoprop. Don't know about MEK but I heard it's similar to acetone.
Yes, MEK is typically used to dissolve or thing things similar to acetone, it’s just considered slightly stronger, but I’ve never some across any job when acetone didn’t suffice.

Thanks for clarifying.
What do you think about using mineral spirits? or paint thinner?
You can actually just paint that stuff on your seams at the first sign of a little bubble leak no clamps and use the board the next day. The stuff works well. :)
I have patched two punctures in an ISUP with that HH 66 cement, 1 of them four years ago......no problems with either hole.
Thank you for this useful video. I have a nearly identical problem. Could you post a link to the kind of clamps you used?
Unfortunately the clamps are 15+ years old. However, they are standard wood working clamps. I created a simple wood strip that I shaped to the edge of the sup to achieve better hold.
Hi! I have the same problem with a seam on my inflatable kayak. Did you have another leak on the same seam you fixed after a while? Also, I am curious to know how you selected the HH-66 Vinyl Cement because I am not sure if that works well for marine/water environments. I am planning to use the Weaver Adhesive 3001. My kayak only requires 3.2 psi instead of 15 psi, so I hope it works.
Hello, no it’s been perfect since the repair. I found HH-66 after doing research on how to do repairs. I honestly think the most important step of all is properly cleaning and preparing the surfaces. Good luck!
Trying this on a paddle board I got for free with a ripped seam. I let the glue sit for about 3 minutes but didn’t test it to see if it got tacky, and I applied a liberal amount. I hope it works! If not I’ll have to try again!!
I’ve been successful with all but one repair so far. The key things are to clean, little bit of sanding, clean some more, glue (not too much, not too little), and they apply pressure as it dries. I messed up the last part on my last repair and it did not turn out well. Good luck!
What type of glue is it?
Has it continued to hold air? I lost 2 in one day to seam rupture. Left them in the sun. Live and learn. Plan to attemp the fix on the oldest one this weekend. If it works, will do the other.
Yes, it has! Honestly I was a bit surprised - but it appears to be as good as new. Good luck!
What glue did u use?
thank you for the video, what did you use to pump your board up?
Thnak you. I use my air compressor with an adapter I found on amazon. I made another video on the channel about that.
please tell me how I can open to adjuste a hole from a bad reparation and do you think acetone can demage the sup ...I love your video
That’s an excellent question and something I am trying to figure out myself. Unfortunately I don’t have a great answer as I’ve never done it. But, I am thinking about trying with acetone. As long as you can open up a space between the layers you may be able to use acetone to loosen up the old glue. Just be careful not to let it sit on too long. Good luck!
Great video, we have a similar ploblem, we just order the hh66 but we have no idea of what grit of sandpaper we should get?¿ any advice?¿ thanks
I recommend something that isn’t too rough - anything 100-160 grit should work. I had to repair a 2nd iSUP this summer and it also worked great. Good luck!
@@campbikeski Thanks!
Which HH-66 should I get? On Amazon there’s one with white can like in this video and the other is green I’m confused anyone can answer?
I am not 100% sure but I think they are actually the same - just newer packaging or size specific packaging. Just make sure you are in a well ventilated area when using this stuff. Good luck!
What kind of glue did you use?
I've got a similar problem and no place to take it for repair. Would like to know how it turned out. Did the repair hold? Did any additional seams split/open? Lastly, how do you generally inflate your inflatable SUP?
Hello. I have done this repair now 4-5 times and it has always been successful. 2 of my SUPs developed more leaks which I was able to fix (apparently due to bad glue). I currently use a combination of a 12v electric pump and the hand pump. Good luck.
What kind of glue did you use? I had exactly the same problem.
It is called RH Adhesives HH-66 Industrial Strength Vinyl Cement Glue with Brush, 8 oz www.amazon.com/dp/B00BUB5JOA/ref=cm_sw_r_cp_tau_NzB4Eb4MVBJJB
Hi! Thank you for the great tips and video! I am in the process of fixing my SUP.
How do you clean the glue excess when taking off the clumps? I have a couple of dry-glue spots after the repair and not sure on how to get rid of them. Thank you 😊
I did this repair and it seemed fine, went to pump it up at the lake, it held well until I got to about 13 psi (it recommends 15), then the seam blew out in the same spot… what to do? Trying again
I have done 6 repairs and all have held. I think the key is to clean well and then let it sit 24hrs before inflating. Good luck.
Any tips on the glue application ? I seen a BIC video where they put on 3 applications of glue every couple minutes before clamping, did you just do one application and wait couple minutes before clamping ? Have a speedy Starboard Whopper inflatable that has very similar blown seam
I roughed it up with sandpaper, applied one liberal coating, and waited a few minutes. It took quite a while for me to apply due to the large rip (maybe 4-5 min). We just went whitewater paddling last weekend and the repair is still holding.
@@campbikeski has still held? My buddy and I both have tower paddle boards, his busted a seam a couple weeks ago and mine did today. He's been too afraid to try to fix on his but I'm not giving up my board!
Yes, still, holding - no issues at all. It’s definitely worth the time to try to repair. Just make sure to clean properly and dry-fit your clamping setup before applying the glue. Good luck!
Bro, which electric pump u used to inflate
When I made this I used a compressor as my Intex pump broke. I finally got an Aquaglide pump from REI which I have been happy with. There is an identical knock off version on amazon but I cannot say if it works as well.
Man U did such a great job showcasing the acetone! But when it came time to show the glue, you just forgot to show us. Can someone please respond with the type of glue that was used? I'd like to use my paddle board this weekend.
It is called HH-66 vinyl cement. Please check the description for a full list of items you’ll need. Good luck!
You realize people
Watch the video for the information?
How has it held up with use since the repair?
Im a bigger guy(280) and my iSUP blew on Canada Day after a 2 hour paddle and left it floating while my Nephew and Dog ran around. It blew out the seam almost the entire length of the iSUP plus a small section on the other side. I think mine is possibly too far gone for a repair that big with a user of my size.
Great video though!
It’s held up like new! I have to give props to Boardworks because they did replace the board right away and let me keep this one as well! Good luck getting yours replaced.
I've used that HH 66 to repair two holes on a body glove ISUP one back in 2018 I haven't had issue with either. The cement if it spreads beyond the patch and dries will discolor a little but you will not get it off. I am 6 ft 240 lbs.
Hi, how is this still going 3 months on?
Still working great! No issues at all. I have had it inflated for several weeks at a time and have deflated/inflated several times as well.
Thanks. Any particular tips, I'm about to attempt a repair of a seam with MEK and HH66. Were you worried about getting glue on the inside on the drop stitch?
I tried my best to avoid it - but I am sure I did not entirely avoid getting glue on the drop stich. Clean, sand and dry fit before attempting to glue it. The template and testing the vise setup dry was a huge help.
What glue did you use?
It’s called HH-66. It’s nasty stuff but it works very well. Work in a well ventilated area.
Anyone know what glue he used?
It is called HH-66 vinyl cement
IMHO a tear like that is a factory problem and the vendor should sort out a new one. I bought a damn expensive top of the range Starboard Astro 10yr ago and it never held its PSI.
Despite complaining to the vendor it would a cost a fortune to return and get a new one shipped out (only if they found an actually problem)
Few years after lots of frustrations… blow out. Massive tear in the seam.
Pissed me off.
I just repair my board by this way. Is it still good after one year ?
Yes, it has held great.
You better stay close to shore
Make a video out of patch of board and you don’t even see what kind of glue you use
