3M 5200 on a dingy?

Yes, yes, I KNOW this is an old thread. But y'all always tell me to do a search first before posting, in case it's been covered, and this is what I found..

I'm in the Turks and Caicos, with a hole in a hypalon dinghy. Local boat supply store ( only one in the nation far as I know) doesn't have any hypalon glue or patch material. I can import patches, but am running into issues shipping flammable glue via usual methods.

I can get 5200 here no problem, also 4200. Does this truly work well to patch hypalon? I need a small round patch for the hole, and also to glue about three feet of the rub rail back on. boat is one of West Marine's 11.5 ft. RIBs.

Any special prep for using 5200 on Hypalon? Normally I'd scrub it with MEK or Toluene and rough it up pretty good with some coarse sandpaper.

Try contact cement

5200 was used by a friend and it worked, but looked very foul

Thanks for the encouraging reply. Did it look foul because it was messy?

I was thinking I'd have to mask the area of the patch off, apply the patch, and then trim the excess ooze that slopped over onto the masking tape.

Other than the mess, did it hold okay? Do you know if your friend considers it a permanent patch, or was this a hold-til-you-it-home job?

i do not know as i left kali when he was still using it... it did last a bit of time, a year at my last knowledge...much white leavings ar edges of repairs..he used it to patch without material....mebbe canvas of some color or sail cloth would improve appearance and mebbe make patch last a bit of time....

ah, NOW I got it. He just smeared 5200 over the hole and used that as the patch. That's actually pretty encouraging.

No 5200 is crap on hypolon. But it will do fine, or 4200, till you get some 2 part hypolon glue.

In fact as it will be a temp job the 4200 may be better as it will be easier to get off.

On my old dinghy 5200 came off fairly quickly. But I would think it will give you a few months before its critical again.

Wow this is still alive...
I am the OP, I cleaned the sections needing repair with acetone. Applied 5200 and clamped, walk away in disgust and 2 days later went into service to the present with out problems.
I'm happy to report my repairs with 5200 have held up so far.
Still my next one will not be an inflatable...
Looks were not great, but then again I made no(great) effort to make it look nice. I was teed off and it was this or the trash. I believe it could be done in a way to make it look nice.

I did find an original container, unopened of the real Weldwood contact cement on board when we bought the boat. This is the pre non-flammable i.e. the good stuff. I'm sure it's still on board, although I didn't check to see how old it is. It's still liquid and sealed. Would that be a better choice for a repair until I can find the real hypalon stuff?

There's nothing in the plumbing aisle that would work, is there? I know there are several types of PVC glue around. Very limited choices here. I might be able to find Gorilla super glue.

Yes, use your contact cement. Let us know in a few years how it worked

[Canibul]

got patch stuff on the way. Still scrounging the island for suitable glue.

We have been using super glue for years on small holes on our Avon and AB dinks. For small punctures we only let a little air out, scuff the area and the patch. Smear some super glue on it and press the parch on. 4 minutes later we are back in business. So far none of the small larches have leaked. I have to admit most of these holes were caused from fish spines or sharp rocks.

Good luck

I have used 5200 for trim. Happy with the result, but wouldn't use on structural or hole repairs. Better stuff is Bostik NE486/2402. Two part and designed for the job.

[forsailbyowner]

Best results ive seen are with the stuff you pour inside and roll the dinghy around. Ive only heard of successes using this stuff.

We used 5200 on our elderly, but hard working Avon hypalon dinghy and it has worked great for over 3 years.

We used it with a hypalon patch, kept it somewhat deflated while it set overnight. No problems, looks neat.
