ZacOps · 16 June 2013, 23:13

Hi all, I need a little advice on fixing a patch that came off this weekend at Lake Nacimiento (The Dragon). See pics

Zero experience patching or fixing patches.

(1) There's lots of threads on repairs so do a search
(2) Its all about the prep.
(3) Make sure you know what the materials are made of and you have the right glue and instructions. Hypalon and PVC are not interchangeable.
(4) I've no experience with your toluene replacement - it might do the same job, it might do almost the same job, or it might not.

The toluene replacement will be fine for cleaning-it's got acetone in it. It should remove excess glue too. I've used acetone for both cleaning tubes and removing excess glue in the last few weeks.

Don't know about using it for thinning glue, but I suspect you won't need to thin the glue for that patch.

GIVE THE FLAP A ROBUST SANDING WITH THIS BUT BE MORE SENSITIVE TO THE PREP ON THE TUBE ITSELF BE CAREFUL NOT TOO CREATE TOO MUCH HEAT ON THE TOOB

Rogue Wave,

Thank you. Follow up question; should I be overly concerned about the separation of the top layer of the tube to the back of the patch? I opted not to remove the patch completely, so I am stuck with that light grey material separated from the darker inner tube material.

I am just going to do my pest to prep everything and piece it back together as best I can an hope it holds.

Replace the patch completely. The section you're going to glue on is frayed. Remember - preparation is key.

Spartacus,

Thanks, should I pull the whole patch even if it takes off more of the top material? Seems a little counter intuitive because when I pulled it back it exposed more of the darker material. If I use my solvent can I pull it off cleanly? The patch is about 1/3 off.

You can use a little heat from a hot air gun. You need to remove that patch.
It will be much worse going back and redoing a leaking/ poorly applied re-patch and newly applied glue.

Just take your time and follow glue opps you will find with a search.

Cheers, Squid

Squid,

Thanks, I will try a hair dryer. Cut a new patch or clean and replace the old one? Size and shape is unique and I am concerned about gettin it right.

New patch mate, I would walk ya through this but off to sea.

Cheers, Don

Get rid of the old patch entirely and throw it away. You need 2 brand new patches. For that large a hole you need an inner and outer patch.

Lots of threads here with patching instructions.

Captnjack,

Inside? I would have to cut into the tube. It is holding air now. That sounds really destructive.

ZacOps · 18 June 2013, 02:58

Step One: Used hair dryer to pull the patch back and carefully keep most of the top layer of the tube.

Step Two: Cut away excess fabric exposing inside layer of the tube.

Step Three: Pause to reflect on how gnarly this looks and ask for more advice before I cut into things. I will be sanding off the glue while I wait for some mates to post advice.

How do I best fit a patch for a tapered cone? That is some higher math.

Can anyone recommend a shop in California near San Luis Obispo that can repair tubes? Santa Barbara, San Francisco or Ventura.

This is beyond my DIY skills; complex cone repair.

Sal's inflatables in Alameda; kind of a opinionated guy, but the only one in my area.

Used to be a shop in Ventura (more of a retail place); don't know if they're still in business.

Luck;

If you're searching for a repair shop, try rafting places as well. I suspect there are more of them than actual marine repair facilities.

Sorry I didn't realize this was just the outer layer of hypalon and the inner layer plus scrim was still intact. So no inner patch IMHO.

The circle is too small. You probably want an egg like shape with the tip of the egg pointing towards the tip of the cone. Minimum 1" overlap of the patch onto solid intact fabric.
