Dink Air Leaks

Have had my little Baltic PVC RIB for seven years. It has NOT been babied, to say the least, and has never missed a beat until now. It has recently developed air leakage which seems to be some sort of general bonding failure because it has happened within a short period of time in two or three spots. Has anyone had any luck fixing these things with the pour-in stuff or is it ready for the landfill? It really doesn't owe me a dime but it would be nice to get a couple more years out of it before sending it to the big dinghy dock in the sky.

Re: Dink Air Leaks

We've had great luck using a two part epoxy glue (Epoxy 330) on our Zodiac. I still haven't figured out if it's Hypalon or PVC, having been told both from several professional Zodiac reps.
Getting the area to be patched and the patch CLEAN is the number one thing to keep in mind. Serious sanding and removing any residue from that and even oils from one's hands is imperative.
We redid our lifting rings several years ago and they have lasted longer than the job the professional who installed them did, and the dink hangs by them every single night at anchor (350 or so a year).

I'm impressed by marine goop and have had good luck with it on a PVC boat!...Dale

Re: Dink Air Leaks

I've used two part glue over chafed holes, with good success. It takes OCD prep work, as capta says. I've not had any luck trying to cover or reseal a seem. The pros can redo a seam, but they essentially open it all up and start over.

Use a spray bottle of soapy water and find out where it's really coming from. Could be the air fitting too.

I've located a number of small air leaks via the soapy water technique. A couple (largest) are at the floor/tube seam, one is along a tube seam right on top which is very small and another is by the transom. It seems like the adhesive is maybe reaching its effective life limit. It's actually pretty amazing to me that these things stay glued as long as they do. Think I'll be building a hard dinghy to replace the balloon boat:-)
