Amazing. Fixed a puncture in my hot tub
My hot tin had somehow picked up a puncture. Stick on patches kept failing, this worked perfectly. Was easy to apply. Absolutely no complaints.

Excellent product. Works as advertised.
Excellent product. Used with success on inflatable mattress. Seal provided is strong and dries relatively quickly. When dry it turns milky white. Will Look to use on paddling pool as well.

Works well for holes in paddleboards :)
This is amazing. I had a few holes in my paddleboard from where it's been dragged and scraped, one was at least 15mm long. This stuff is so good, I really wasn't expecting it to work, but it really does. I applied a layer and then another a few hours later, went paddleboarding the next day and it worked, no air coming out! The board has been in my garage for a couple of weeks since and it's still fully inflated! I really thought I'd be buying a a new paddleboard but now I've found this stuff I won't need to :) Very very happy.

Not sure just yet
Received product today, wasn’t damaged but it was out of date.by a year this month 🤨 it wasn’t opened so I’m just gonna try my luck and see if it still works.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.

It’s ace. It works! Get some!
This stuff is ace. Lay-z-spa had a split right on the seem! Tried a few other things and they never held. But this stuff worked. And it’s flexible too. And it’s really bonded to the hot tub material

Very good
Very good, first layer 30 minutes wait, then 2nd layer and 5 hours. Air mattress like new, that whole was so big and not flat surface made it impossible for special tape, and for that price it is a lot of uses maybe like 10 at least. Can recommend and using it again on another hole

Bon produit pour réparer spa
Produit très efficace pour réparer des petits trous dans un spa gonflable intex . Un peu de produit suffit pour colmater de façon durable sous forme d’une petite couche translucide.

Un salvavita indispensabile per tutti i proprietari di gonfiabili! 5/5 stelle
Ho acquistato il kit di riparazione Boat da 40 ml con un po' di scetticismo, ma si è rivelato assolutamente eccezionale! L'ho usato per riparare un piccolo strappo sulla mia piscina gonfiabile e il risultato è stato impeccabile. La colla è potente e l'applicazione è stata sorprendentemente facile, anche se non sono un esperto di riparazioni. Ciò che mi ha convinto di più è la sua resistenza.Inoltre, il fatto che sia resistente ai raggi UV mi dà la tranquillità che non si rovinerà al sole. Il formato da 40 ml è perfetto: è abbastanza piccolo da essere portato nello zaino, ma sufficiente per diverse riparazioni. È un prodotto estremamente versatile, ideale per chiunque possieda barche, piscine, vasche idromassaggio o anche solo gonfiabili da campeggio. Riparazione forte, veloce e duratura. Un prodotto che fa esattamente quello che promette. Consigliatissimo
