3M 5200 on a dingy?

Greetings,
After previous unsuccessful attempts at repairing dingy using pvc glues...
Just wondering why not use 5200 ? It is permanent, flexible, ok in water.

The tubes have separated from the flap that secures them to the transom.
I do not deflate these ever so that is not an issue.... Your thoughts?

We fixed small pinholes on PVC tubes but a bigger structural repair failed.

Mario:
We used it to bond a pvc [Herculite] floor to a 10 yr. old (at that time) hypalon Zodiac. It stayed waterproof till we sold that dinghy five years later, so no idea how it did after that. We were living aboard at the time, and some friends kindly let it dry (a whole week) in their living room. It sure looked big in there!

HH-66 worked very well on my old PVC dingy, I removed the whole floor and transom and re-glued, no leaks. Just follow the instructions carefully.

Re: 3M 5200 on a dingy?

BTW

We used 2 pack from soromap. Works great, but it is way too expensive.

Perhaps somebody knows what the mass market equivalent is?

PS It must be something that reacts to UV - the repairs come out pretty 'dirty' over time.

Sorry for the delay, I was away for a few days. HH-66 is a one-part product, not as easy to use as 5200, but much simpler than two-part glues, which by the way I had previously (unsuccessfully) used on the same inflatable.

It is applied with a brush that comes inside the same lid, similar to PVC pipe glue. The surface has to be as clean as possible (although I have to say HH-66 is very forgiving on this aspect) and lightly sanded (very important). You gently brush both surfaces, let them set for about two minutes, and glue them together. If set time is too long, or if the job is too large and you still find leaks after curing, it can be re-activated with a heat gun, just avoid excessive heat on the same spot as it can burn the PVC.

HH-66 solvent is highly recommended to remove old glue residue and for clean up. I would buy both glue and solvent for any large project.

Both the glue and solvent are very strong products, I would never use them indoors and except for small jobs I would always wear a respirator (not a dust mask, but one with cartridges for fumes).

I've also fixed a pinhole air leak on one of the tubes, re-glued the oar-locks and D rings, fixed another pinhole leak on a flexible water tank, and many other plastic items. This product is amazing.

The inflatable was in very bad shape, and kept as a spare, but as the "primary" one (a fancy one with inflatable floor, inflatable keel, and all the whistles you think you need... until you own one) is very heavy, I decided to fix it. The floor was almost beyond repair from previous failed attempts by the previous owner (silicon glue!), a couple of shops (which deemed it beyond repair), and my own attempts (two-part glues). There where several areas were the floor was open and I started fixing those, and immediately after new portions would open, so I decided to remove the whole floor and transom, and re-glue the whole thing. The floor at that point was in such a bad shape that I bought about one yard of shower pan liner (available at any hardware store) and cut it in 2" strips, which I glued on top pf the floor to tube seems. After that a few spots still needed a little additional work with the heat gun, which I fixed in minutes. This inflatable has not had a leak for the past two years and I had not used the other inflatable again.

Re: 3M 5200 on a dingy?

I gave up on the pvc glues... spent too much on them.
The dingy was repaired with 5200... last ditch effort before it was thrown in trash...
going on two weeks of use with 5 hp motor and kids playing in it, so far all repairs are holding.
Does not look pretty but that is just a theft deterrent. We will update on the longevity of these repairs.
Thank you all for your comments and suggestions.

Regards,
Mario

Re: 3M 5200 on a dingy?

All of the glues I've seen need a zero moisture enviroment to work on PVC. Hard to do in a climate with a 90% humidity year round. I tried repeatedly to glue a Zodiac I had, and finally gave it up and bought a hypalon rib.
