How do i fix this?
I need some advice please i've just aquired this little Avon Typhoon complete with a multitude of leaks along the seams, its been patched before but some of those have started leaking again. I've got some pvc material a bit like a very light grade tarpaulin and i'm thinking of cutting it into strips to go over the top of the seam all round? to bond it would i be ok using sikaflex/polyurethane adhesive (strong but still a bit bendy) or do i need some of the 2 part adhesive that i've used to patch hypalon but for plastic? I'd be grateful for any tips or suggestions on the best way to tackle this thanks all!

Hi Mate,
The key here is to be thorough and take your time. Make sure you have the correct material either Hypolon or PVC according to what your boat is made of.
You need to use two part for a really good bond, don't use Sikaflex it's not permanent enough to really glue things together and is more of a sealant than adhesive.
Make sure you sand or "key in" the material that is to be glued, then clean it with thinners.
Use three layers of glue on the patch and surface and wait 20 mins between each application.
After all three are almost dry, then attach the patch.
As for all the niggly leaks that may be too difficult to fix, there is a Marine version of the stuff you put in bike innertubes specifically for inflatables.
As for covering the seams, use it as a last resort after trying the "innertube" solution.
If your still having problems and a pro is too expensive, you may have to write it off.

Don't worry, it's still good stuff for transom work so hang on to it. Get some two-part on Ebay for a fiver. There's also material on there too.

I'd bin it.
You need to find out if its PVC or hypalon, then buy the respective glue and thinners, two coats will do letting them go tacky/dry once the patch is on roller is hard to make sure it takes.
What gave you the idea of using sikaflex.......

leaking typhoon
Hi Chewy its PVC
reference the sikaflex the leaks are coming from the middle of the little white strip shown in the 2nd pic this overlaps where the tube meets the floor and its stitched all the way along seemingly into the bottom part of the tube? don't quite understand how it works thought they were just like rib tubes bonded onto a plastic floor? where it leaks is where the stitchings broke anyway i've squidged a small bead of sika into/along a small section of the deepest part of the stitching/crevice (excuse the rude word) and its held it? so i thought if i could sika a pvc overlay strip on top of the whole white strip it might work but like you say i think its heading for the bin

Hi everyone, I've just been given a Typhoon T3 by a mate whose bought a
Honwave.
It looks exactly the same as shoestrings boat including the colour. The only difference is its probably a bit bigger,and it has a wooden transom.
There's a metal plate on the transom with the model details ,it also says
Avon International. So I would say shoestring that you have an avon.
I also have air escaping from the seams. That's why I've just registered.
I can't decide wether or not its hypalon or pvc!
Any idea would be greatly appreciated so I can buy the correct glue etc.
Regards,Bob.

Hi there mine was definately pvc and after too many hours of fannying i surrendered to chewys advice and binned it although i did manage to sell the seat and outboard bracket on ebay. I did attempt an overlay repair with sikaflex (as its my answer to everything) and this did seem to work but i could tell it wasn't going to last on a longer term basis especially being folded up in a bag/ being reinflated on a regular basis. I decided it wasn't worth the risk of it going tits up and me the dog & the Mrs (in that order) getting a dunking. I guess with the correct adhesive it may have been more of a success but i wasn't prepared to put any more time into it, anyway i wish you good luck with it hope it works out for you
regards AL

Looking at your picture, I'd say that is PVC. Hypalon is kinda rubbery and doesn't usually take on that slightly bent crinkly way after being folded.
If you're going to glue it, do a ribnet search and you'll find how to do it. You'll need adhesive, some PVC fabric and MEK. Thinners or acetone are not what you need.

Typhoon repairs
Thanks for the info gents, mine certainly has a few crinkles in it so it looks like getting PVC repair stuff.
Now the choice is between polymarine 2 part adhesive, IBS PVC Boat adhesive & activator, or HH66 Vinyl Cement Adhesive.
Your opinions on the best choice would be invaluable to me as I am a complete novice at this sort of thing, even at my age!
I also have my eye on some MEK on Ebay for the prep work.
Many thanks,Bob.

I don't know the HH66 but either of the other two will be fine.
