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

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).

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.

Work great for my blow up couch that I got fixed the problem and never had a leak in it again

Better than any other patch I have used. As long as the hole is not near a seam - this one is the one.

I just used this product to fix an intex durabeam air mattress that I accidentally gashed with a picture frame. The gash formed a slit in the vinyl about two inches in length, and is shown in the photo. So far, here are my observations: 1) The box delivered to me was in good shape, but when I opened the box, I noticed that one of the smaller, pre-cut patches had partially detached from the wax paper backing, and adhered to something else in the box. Luckily, I wasn’t intending on using this piece anyways (too small for a two-inch gash) but regardless I was nonetheless able to move the patch back onto its appropriate place in case I need to use it another time. 2) The patch material is clear, so the patch becomes less visible when adhered to the vinyl, regardless of its color. This was desirable for my application. 3) Comes with two alcohol pads to prepare the application area. 4) It has been roughly 8 hours since the application of the patch, and it appears to do a good job of adhering to the vinyl, although I have not yet inflated the mattress as the patch needs 24 hours to cure. Steps taken: I deflated the air mattress on the floor, and pressed the sliced portion of the air mattress so that it was totally flat and parallel with the floor. I made sure there were no wrinkles in the material, and avoided any pleats underneath the damaged area to ensure flatness. I took measurements of the gashed region, and designed a rounded patch shape that exceeded the edge of the slice by about one inch on a computer, printed it out, then taped the printout to the included patch, and used scissors to cut the shape out of the patch material. Then I thoroughly scrubbed the damaged air mattress area with the included alcohol pad, making sure to clean everywhere where the patch would come into contact. I then turned on the fan in the room to help the excess alcohol evaporate, which only took a couple of minutes. Next, I placed my customized patch with the protective backing still on, and moved it until I was satisfied with its placement, making sure to try to keep the edges of the patch about one inch from the tear. Then without allowing the patch to slide, I removed one small region of the protective wax paper on the side of the patch, and pressed it against the vinyl air mattress. I then used a debit card in my wallet as a squeegee, and simultaneously squeegeed while pulling the protective backing off, allowing the patch to remain perfectly flat and aligned during application, and ensuring no air is trapped under the patch during application. When the entire patch had been applied, I introduced strong pressure with my fingers, and also the plastic handle of a pair of scissors to help ensure thorough contact between the surfaces. I went over this multiple times vigorously, making sure that all the edges were also well-adhered. The instructions say that a heat gun may be used to expedite curing time, but I don’t have one, so this technique was not used in my case. The instructions also indicate that the strength of the bond (for the type B patch) asymptotes to approximately its final value in about 24 hours when a heat gun is not used. I intend on inflating the mattress only after at least 24 hours has elapsed, so I will have to return and update this in the future. So far, the solution seems to be working as advertised, although I have deducted one star for the poor packaging that led to one of my stickers partially detaching from the wax paper backing, and sticking to other objects in the box. Luckily, this development did not affect my project, since I only needed the larger patch, which shipped without detaching at all. EDIT: It has been a week since I performed the repair. The repair is NOT a permanent solution, at least for a 2 inch gash. On at least two occasions, I woke up on the mattress when I discovered that the mattress was losing air. For this kind of hole in a pressurized air mattress, the patch stretches as the vinyl expands due to the inflation. This allows the tear to bulge open wider, which allows the vinyl to spread away from its original position, which can gradually cause the patch to peel slightly on the edges. To make matters worse, since the patch doesn’t hold the tear shut, the corners of the tear tend to continue propagating, making the problem even worse. I ended up with the tear spreading much closer to the edge of the patch than I had started with, which ended up causing leaks. In order to reduce the likelihood of leaks, I had to use my fingers to press down on the patch before going to bed every night to make sure to re-establish the bond. Admittedly, This product would probably have worked better if I had made the patch longer in order to account for the tear growing after application of the patch. My leaks always occurred on the left side of the patch where there was no longer sufficient distance between the tear and the patch edge. Also, I could imagine that this product would be adequate for pinhole punctures, which wouldn’t have a tendency to continue spreading open and tearing. I could also imagine that this product could work for a long gash (like the one I have) if a before application, a few stitches were used to forcibly hold the gash closed. Then when the patch is applied over the stitches, it would be the stitches, not the patch itself, that would bear the spreading force. Then the patch would probably be able to do its job of making an airtight seal, which it seems to be quite good at.

I’ve used these to repair holes on Halloween and Christmas inflatables of every size and color. Some of the previous repairs I’ve made have lasted several years without failing. Definitely need these in your repair box. Easy to use. Just follow the directions. You can cut them to size. Just make sure you patch with a piece that is probably 1/2” larger than the tear, so the patch has something to adhere to. It is thick enough and flexible enough to endure multiple holiday seasons.

It failed really bad on the aerobed It did not seal the small hole in the mattress. I let it sit for three days before re-inflating as soon as the mattress is full It’s separated from the mattress in the air escaped. So it is not really recommended to mend an air bed.

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.
