pinhole leaks in Hypalon

[marbra]

Can someone tell me if a pinhole leak can be repaired the same way on a Hypalon boat as an PVC boat. I used pvc glue on my Bombard and applyed it directly on the leak and it worked fine. But I'm not sure if I can apply it the same way on my Avon. (Useing the correct glue of course.)

Thanks for any replys,

Mark

I don't think so.
Whenever I had a hole or a small hole (pin hole) on Hypalon tubes I had to patch it up properly.
This is what i was advised by a hypalon tube company in Greece.
I think that you can just put some glue on PVC and let it set cause is different glue and material altogether.
IMHO, PVC be repaired much easier than Hypalon
With hypalon you need to rub with sand paper both surfaces quite a bit, clean it with acetone or something similar, apply glue on both serfices let it dry a bit and then stick the paches together rub them hard and after that you'll have to wait for a while to set. With PVC clean surfaces with white alcohol spirit or acetone (acetone takes some colour off) just apply the glue on both surfaces, let it dry completely, use a hair dryer to warm it up a bit and stick both surfaces, rub them hard and in 10-15 mins is as good as new

Hi you could try this but I not shore how you would try & get it all around the inside of the tubes if your rib is over 5M long!
Easy with a sib.

If it is truly a pin hole, it'll probably be fine.You will need no pressure unside the tube. If you judged it properly, you could even arrange for the adhesive to be drawn slightly inside the hole. The adhesive does degrade in sunlight but it takes a good while.

Try it and let us know how you get on.

On one of our clubs AVON SIB’s we had a couple of small leaks in one of the tubes while on holiday, to do a temporary quick fix we deflated the tube and applied a few blobs of Aquasure.
These are still there 4 years later & they have stayed on better than some of the patches.

And it Say's not for Hypalon on the Aquasure tube! I take it they are Hypalon tubes?

Yes Nick they are Hypalon, Didn't know it said that on the tube, & NO it wasn't me that done it.

[Nick Hearne]

But it worked, & still is, so what the hell!

[Jackwabbit]

yes it's still there.
This is one of the problems with having over 40 people use the boats, they all think they know best, & some things that are done work or are an improvement while others dont.

Last year after some fishing trips, one of the guys landed a good sized bass and put it down heavily on one of our tubes. 3 of the spikes in the dorsal fin punctured the tubes and left us with tiny holes.......

We basically deflated the tubes, put a good sized blob of superglue over each hole ( I know sounds kind of weird ) and then use a hoover to take out the last few bits of air in the tube. We hoped that it would draw some of the glue into the hole.

Still holding to this day
