Dr Boat Heavy Duty Repair Kit for Boat Kayak, Canoe, Tent, Inflatables, Swimming Pool, Hot Tub - LIQUID PATCH Resistant to Fresh and Salt Water UV-Resistant Long-lasting - 40ML

I used this on an inflatable kayak and it’s great. Dead easy to use, and it works. Superb stuff.

After trying the lazy spa patches I was about ready to give up and throw the hottub out because I SUCKED at using those. Fixed one hole, great, fixed second and then the first sprung again.In a last ditch effort I hunted Amazon for anything else that could help and found this stuff. It's so easy to use that even this idiot didn't get it wrong. Super gloopy and it's a surprisingly small tube BUT it is so worth the money.It fixed the two holes we had and then we found a third and it's fixed that one right up too.It doesn't look pretty but honestly I couldn't give a monkey about that. I also got it on my fingers and it was really easy to wash off. Honestly very impressed with this stuff!Will definitely use again in the future. I just searched on YouTube before using it to check I was doing it right as the instructions on the box aren't a great translation.

Was cautious of using it. But actually it worked really well. It’s very “gloopy”. Used it in a small hole on a blow up kayak. It took 12-24hoira to fully dry and seal. Being inpatient I expected immediate effort. But I left it outside for 1 day, and it was fully secured. I made a poor cosmetic job but that’s on me. Very much recommend this product.

Tried a few other solutions involving waterproof tape and they couldn’t take the pressure of the combo of water and air from our blow up hot tub. We were considering chucking the spa away as we couldn’t get any patches to work. Saw this on Amazon and thought we would give it a go.It was very easy to use. We deflated the spa, patched the hole with Dr Boat, 2 layers of it with a 15 min gap between each application, and waited 12 hours for them to harden. We filled the hot tub with air and water - voilà! no air leak. Has been holding air well ever since. Excellent value for money. We love the stuff and is essential for blow up spa ownership.

I must admit I was very sceptical about this product as I was told the puncture I had on my base bladders on my kayak might not be repairable and was going to be charged £49.99 to be attempted to be repaired. so I thought id give this a go. I can honestly say that it has %100 worked. the slice in the bladder was about 2cm wide very close to the seem. its been inflated and has stayed up. excellent product 👌

Received product today, wasn’t damaged but it was out of date.by a year this month 🤨 it wasn’t opened so I’m just gonna try my luck and see if it still works. The glue itself inside looked fine and was applied to damage patch on the hot tub fine with no issues and easy to use, I’ve just applied the 2nd coat and it seems to be setting quite quickly as its feeling less sticky … but that might be because it’s 30+ outside 😂 i will be updating this review at a later date with the results and so far I’m optimistic as already the patched area feels firmer and sturdier than previous fixes👍🏻😊not sure about the price as it was a smallish tube and just about covered the fix but if it does set and there is no leakages so I’m hoping it was worth the money.

We were gifted a hot tub from my friend and this was the only thing that repaired it, the lay z spa repair kit was shockingly rubbish and this stuff is super strong and actually fixes the issue

Terrible. Had a very small puncture in a kayak. Put this on and followed the instructions. Then pumped the kayak up and it ripper the hole making it 10 times larger. The product cant deal with the pressure and sticks to the kayak causing it to rip more. Avoid.
