PVC Stitch Liquid Patch

I got this to patch up a small hole on my 18ft pool. It’s September and it’s still holding on. Very easy to use

I barely bother with reviews, but when something is this good I feel obligated to write one. We’re not talking a minor evolution or some sort of gimmick. This is a true breakthrough. My hot tub cover is an air mattress type and for some reason it gets small holes right where seams are or two pieces of PVC join. I’ve tried everything, sticky stuff, all the kits there are. This product is the only one that works, and it is truly remarkable. I swear I would pay five times what they want for it now that I know how well it works.You glop it on just like the instructions say without pressure in the air mattress as soon as you’ve identified the hole by brushing on soap and water which bubbles right where the hole is. You clean off soap with a water rinse – I use a little bit of rubbing alcohol afterwards to make sure it’s really clean - and then you glop on this PVC cement. It dries in 15 minutes and in two hours they say it’s fully cured. I think it’s faster than that - and what do you know independent of curves and seams and structures that make it impossible for tape to adhere, this thing works. It is so good. I’ve told all my friends and I think it should be in all top best products of 2026 list. It truly truly works.

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.

This works perfectly for sealing holes. I used it on a Coleman air mattress I bought used. It had 2 puncture marks on the top and a matching set on the bottom. Multiple layers of duct tape didn’t work, so I tried this. Because the holes were on both sides, I had to do them one side at a time. It is easy to apply and took only a few hours to dry, so I was able to complete both sides in a day. I inflated the mattress and even had my adult son (about 200 pounds )hang out on it for a while watching tv. No leaks. I left it aired up for 3-4 days and my dogs jumped on it and slept on it, still no leaks. I think it’s ready for our next camping trip. Some have said that it dried up after the first use, and I have noticed that the cap isn’t completely secure, so I put a small square of tin foil on the top before screwing the lid on. Hopefully that will help, but I guess we’ll see.

Dried like it said and is flexible. Easy to use

Worked like a charm on my air mattress. It had a small leak and this sealed it right up!

Worked well. No patch needed. Air mattress held air very well after applying the liquid patch.

I never thought this product would work, but I was wrong! Just spread it over the leaking area, wait until the next day. It stretches as the air mattress are being filled. Repaired a hospital air mattress and my backpacking one. No problems since.

Amazing product, fixed pinhole punctures in my inflatable Kayak cushion (smooth surface), as well as my inflatable couch and inflatable foot ottoman, also with pinhole. For good measure I put some on a wear point on my Inflatable standup Paddleboard. Very happy with it.

رائع بصراحة ، وهو سائل كثيراً لذلك لابد أن تضعه على شكل طبقات متفرقة في الوقت ، بمعنى كل ساعتين تضع كمية خفيفة وهكذا عدة مرات حتى تتشكل رقعة صلبة، لانك لو وضعت كمية كبيرة مرة واحدة فسوف تنسكب المادة لانها سائلة جدا، لذا فإن وضعها بكميات بسيطة بشكل متكرر هو ما يضمن تشكل رقعة متينة وقوية

Todo muy bien

Used this product to repair a number of air leaks in my ageing Stand Up Paddle Board that were unable to be repaired with patches. So far, the repairs seem to be holding up which is a big result as otherwise, the SUP was destined for the tip!

ممتاز جدا جربته على مرقد الهواء ثابت وغطى القطع بس لازم تتبعون التعليمات بالضبط علشان يكون نتيجته ثابته
