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.

Works well repairing inflatable canoe and paddle board.
Worked well when repairing our inflatable canoe. Easiest to apply once the item being repaired is deflated.

Worked like a charm
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.

Absolutely amazing hot tub repair.
This stuff is amazing. I honestly thought I was going to have to tell the wife we were going to have to bin our hot tub. We’ve not used it for over 5 years and tbh I probably didn’t pack it away properly. So when I blew it up on Saturday I found it had 5 holes in it. I tried the layzspa patches which were rubbish. This repaired all the holes and I’m confident they will hold. Can’t recommend this enough. Small price to pay compared to an angry wife and a new hot tub.

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Received product today, wasn’t damaged but it was out of date.by a year this month 🤨 it wasn’t opened so I’m just gonna try my luck and see if it still works.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

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

Hot weather to blame !!! Seemed to get blamed for everything else!!!!
No good this time … product is good have used before However it must have stored wrongly as the bottom of the tube had blown open So there was nothing left of the contents!!! Just a congealed mess Saved enough to fix the job Too messy to send back !!!

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
