Vinyl Inflatable Repair Kit, Yellow Box Type B, 1 Pack

I elongated the seam tear in my air bed, so I could get my index finger inside the seam tear. Cleaned inside around tear with alcohol wipe. Cut two patches to cover tear and extending at least 1 inch all around tear. Removed protective paper from one patch, and cut it in fourths, then re-applied the 4 pieces of paper , back on the patch. folded this patch in half, long way, so protective paper was inside it. Slid patch inside tear, with bed completely deflated, and opened up patch inside of bed with paper side up. Used hemostats to remove one quarter of paper from patch inside bed and pressed down on top of bed to start contact with inside patch. Removed another fourth of paper and pressed down on bed smoothing out and removing air bubbles as needed until inside patch was completely in place.Ensured while installing the inside patch I was closing the tear and much as I could. Next took very fine sand paper and , removed top layer of cloth material from top of bed and around complete tear until area was as large as second patch. Cleaned area with alcohol, then I used Coghlan's Airstop Sealant, and put five layers of it along tear, letting each layer dry thoroughly, before applying next layer. Once 5th layer was dry, I spread a layer of the Airstop Sealant all around tear covering an area the size of the second patch and placed second patch in place, while sealant was still wet. Worked very quickly to smooth out entire patch and remove any air bubbles then let dry completely. Finally, I placed a layer of the sealant around the entire perimeter of the top patch and let the entire repair dry for a total of 24 hours, before inflating the air bed for use again. It's been in use for 3 - 4 weeks now with no issues. Patch work looks great.

I bought these to repair a tiny puncture leak on my iSUP. My iSUP would hold proper air pressure for a few hours but not days. I partially deflated the iSUP, cleaned the area with 70% isopropyl alcohol and a rag, let it dry and applied the patch. It held most of the air in but bubbled under the patch. Whoops. It still did a decent enough job that I felt safe on my iSUP but decided to redo the patch job once I was home. The patch was easy enough to peel off. My bad for not completely deflating the board. Round 2: after peeling the original patch off, I cleaned the area thoroughly with acetone and a rag. I cut a bigger patch this time but didn’t do a very good job of getting all of the air bubbles out. Shoot. Went ahead with it anyway, and used my heat gun to help cure the patch faster. Decided to use the smallest little patch directly over the puncture as a second layer and used my heat gun on that too. This seemed to work just fine even with the air bubbles! I’ve taken my board out two times since then (pumping it up and deflating) and it seems to work much better the second go around. I’m happy with this product and would definitely repurchase to fix another leak if needed. Much easier than getting vinyl adhesive (my iSUP repair kit had a patch but no adhesive).

Went camping over the weekend and never checked my queen-size blow-up mattress before we left. Well lessoned learn to check. Finding out the hard way that the mattress didn't hold the air and, sleeping on the hard ground was not fun. Back home found two holes underneath. After reading other types and reviews I purchased this kind. Works great. Simple application with an easy peel and stick application. Best to follow instructions for proper adhesion capabilities. Highly recommend.

This patch material exceeded my expectations by successfully repairing a significant cut in a tube. Taking the gamble paid off BIG time, saving us more than $100 on a replacement tube for just $10. Pictures truly are worth a thousand words, and I have more patch material ready for future repairs. It even covered a hole in our vinyl pool. I’ll definitely be purchasing this product again. Highly recommend! Served a week worth of fun and abuse and appears to have many more.

I purchased this product hoping it would mend a small (~1/4" tear) on an exercise ball that got punctured by a phone charger. Upon opening the package, two of the patches were peeling back and one of those had stuck to the paper backing of another patch, rendering it partially useless.Although this product is designed for inflatables and vinyl materials (exercise balls are both), the instructions do not specify whether you should apply the patch while the item is inflated. I was worried that inflating the ball after patching would stretch the patch too much so I partially inflated it and applied the patch.I then used a blow dryer for about 10 seconds to help the glue set. Note that the instructions say you can use a heat gun at 350 degrees Fahrenheit to speed the curing time. Blow dryers generally heat to less than 200 degrees. The heat apparently softened the patch enough that the pressure from the air inside the ball puffed the patch material out, and it distorted the tear in the ball so that rather than a slit it was now a gaping, almond-shaped hole. I let it cure overnight, but the spot was still bulging the next day. Worried that the patch would not be thick enough to protect the hole, I applied another patch without heat and let it cure overnight again.The following morning when my husband used the ball, the first patch started leaking air, and the tear grew from 1/4" to about 2" long. Because the ball material warped while heating, I was not able to line up the tear while deflated and repatch it. So I'm out $12 and I still have to buy a new exercise ball.Based off of my experience, if you are trying to repair an inflatable object, first deflate it and make sure the tear is lined up tightly before patching so that (hopefully) inflating will not stretch the tear out. Don't use heat unless absolutely necessary.
