PVC Stitch Liquid Patch – Air Mattress Patch Kit Heavy Duty, Inflatable Patch Glue for PVC & PU, Inflatable Boats, Rafts, Kayaks, SUP, Hot Tubs, Waterbeds, Bounce Houses. Waterproof, 3-hr Cure, 20 ml

Great PVC glue to fix boats and rafts.This glue fixed my inflatable paddleboard that needs 15 psi. I globbed some glue on it and let it sit overnight even though it says it can cure in a few hours. The leak was a small 1cm crack thay was a slow leak, not a full slice into the side. Blew it up to 10+psi and no leak!The repair seem flexible and hopefully will hold up.I also used it to repair an inflatable raft that only needs 1 psi. Im sure it will work on the low pressure raft but I havent inflated that one yet. The previous sticky patch I tried on the hole didn't hold so it needed this stronger flexible PVC glue. It was also about a 1cm long hole in the raft.Im keeping it in the freezer to keep it supple so I can use it again. But for the price, it's worth even just one fix and I already got two out it. Great value fir the money.I included a pic to see the crack versus the size of the tube of glue.

Got this on a last ditch gamble for our air mattress. I am glad I did! It worked like a charm. We’ve used the air mattress at least 3 times since patching it with this and no air loss. Easy to use, but follow the directions exactly. Would definitely recommend for use.

Has to be one of the best products I have bought. Easy to use and only takes a couple hours to fix a float or tube. Use it all the time to repair cheap pool inflatables.

The product does work. However, I noticed that even though I patches the hole in my air mattress to my best abilities, the mattress still does deflate a bit more than normal. It's not even close to how deflated it was without this problem, but bottom line is that it fixed about 95% of the issue not 100% of it. I would definitely recommend this product tho!

This might seem expensive but compare it to the cost of a new air mattress at $100 - $150 for anything decent (internal pump and made of PVC, not vinyl).I had to repair a spot where the seam separated. I had left it a tent pumped up pretty firm and the day got up into the 80s. It still probably would have been fine if I hadn't off taken a nap on it not letting some air out first. Operator error.It can be seen in the photo, about 1/4" in length. I had previously tried another product which used an adhesive and patches. This did not work for 2 reasons. It was a seam but more importantly when the air mattress is pumped up it stretches. This will pop the patch loose because they don't stretch the same. I tried putting successively larger patches (2) over the original patch. It held for one night but only because I used a heat gun to carefully heat up the patches and mattress while it was pumped up. The varying stretch though made the patch start leaking again. It was remarkably easy to peel the patches off to use PVC Stitch so they were never really well attached.I spoke with the owner of the company and did the following on his advice (love small companies. He had tested this product himself on various items including a BC bladder to more than 3 atmospheres. That's quite a bit more pressure than any air mattress will be under).I cleaned the area with 90% isopropyl alcohol (air was out but not sucked completely flat using the pump). I set up the mattress so the split in the seam was at the bottom of a shallow indentation. This was the hardest part because the mattress kept shifting. I used some light weights to hold it in place. I opened the tube of PVC Stitch and squeezed out enough so the seal would extend 1/2" on all sides of the split, and let it dry. Don't spread it out just let it flow out by itself. It will spread a little and flatten out by itself.As a note, I had asked how long the tube would last once open and was told to close out back up immediately. Do not let the tube sit open. It is about 80% solvent which is how it melts the surface of the object you're trying to repair do that the PVC Stitch is unitized with PVC or vinyl to trying to repair.I made the repair at about 65° F with under 50% humidity. I waited 24 hours to pump it up again but I was assured that it would be usable in about 2 hours (dependent on temp and humidity. Affects how rapidly the solvents evaporate). When you can no longer smell the solvents in the repair area is good to go.My air mattress is PVC which is the strongest type made and stretches the least (although they still stretch a little).I used it last night and it didn't leak a bit of air.This product saved me a lot of money, not to mention the fact that this air mattress is no longer available.Since this split when I was camping I had to go out and buy a replacement. The replacement leaks from the inflation, deflation port which apparently is a very common problem with this design. There is no way to fix that. The result is that a supposedly normally functioning air mattress has to be pumped up 2-4 times a night.My repaired air mattress is working flawlessly thanks to PVC Stitch.Thankfully I didn't throw it out even after the first attempt to fix it failed.

Did not work reattaching pieces back onto Brig Hypalon dinghy. Did not hold at all.

So far, I have fixed four pin hole slits in a twenty year old air mattress that belonged to my mom. After applying the product and letting it dry, I have laid down on the mattress and not one of the four repairs leaks. Five stars to a great product.Please note that I spread the product at least 1/4 inch around the hole so that the product has more surface space to adhere to the vinyl.Request to Amazon Vine. I was a member of Amazon Vine last year (2023) and then had some medical issues in the first half of 2024, where I was unable to actively participate in Amazon Vine. Unfortunately, Amazon Vine dropped me from their program, due to inactivity. I would like to request that Amazon Vine reinstate me into the program.Thank you.

There was a 2mm tear on my air mattress. The sealant did seal the gap, however, when I inflated it again, a bubble appeared underneath the sealant. The sealant is like a layer of foil patched on the mattress surface, but not sealing the hole. So I didn't pump the mattress to the psi I used to do, because I am not sure how much pressure the layer of sealant can bear.
