Bad news - the repair I made has failed. Same issue - glue delaminated. This £10k trip is in tatters.
Im going to do it again tomorrow but I need a way to remove the old glue. I have acetone not no heat source here not even a hair dryer. I have sand paper.
Im using adegrip 2 part PVC glue and the instructions state 72 for a full cure ??? Really ?
Any advice. Gladly received
Totally gutted

I am really sorry to hear that Rake.
Perhaps these "English" instructions may help:-

I would spend time removing all the old glue with whatever you have (is there nowhere in Sardinia that you can buy a small grinder-dreamel as in #22) before trying it again, and unfortunately if the instructions say 72hrs then that's what it is.

A friend of mine hired a RIB in Sardinia for a few days. Wasn’t over expensive iirc. He was down south away from the millionaires.

That's unfortunate.
Sandpaper will do the job but you'll need plenty of elbow grease and some 120 - 180 grit paper.
Try to pull apart the remaining bond to make sure you're revealing the full extent of the failed glue. It feels a bit like you're making the problem bigger but in reality, if you can pull it apart by hand then it's already failed. Full cure is in around 72hrs but it's bonded solid inside of 48hrs.
Perhaps most importantly, you need to apply loads of pressure when mating the two prepped surfaces. I do it with a little vinyl roller tool but you can work it with the handle of a screwdriver or any other blunt tool that you have to hand. Be sure to follow the directions of the glue as wait times between applications varies from one brand to another.

A photo of what you're dealing with would help advise loads.
I've had an associated holiday issue where a new under warranty outboard failed two days into a 14 day holiday which was to be 100% boating. We trawled round every local place associated with boats and found someone (not a hire place) who had an outboard they would hire us to save the holiday.

This might be a stupid observation but have you tried tightening the valve down. The external doubler is only there as reinforcing and if valve is correctly tightened down then air shouldn’t be able to get between the two layers, despite glue failure.

My mind was moving along a similar path hence saying an image might help us offer advice. I was even wondering if this valve is OE or a poor DIY by previous owner?

If its just a prv then I'd strip it out & fit a mechanical clamping repair something like the picture would be ideal but if not available then you could easily make up some form of clamped temporary repair rather than waiting 3 days for glue to dry which may fail anyway

What a great idea. Worthwhile carrying one all the time as a "just in case" emergency repair.

I've carried a couple of Clamseals for about 15yrs now. A brilliant device that in some skewed way of thinking I'm sorry not to have had the chance to use and report on.

Although a great emergency tool not sure a Clamseal is such a good idea. Totally unsuitable for a high pressure drop stitch floor. Even if you trimmed away the stitch links it would never seal against the rough inner surface.
The last thing the guy should be contemplating is butchering up the valve/prv area.
On a side note, god knows why any manufacturer would be fitting prv’s to a drop stitch floor…but then I’m not an expert on ‘rescue grade’ inflatables

I’m sure one of the most valuable skills that any boater can have is how to adapt/overcome/survive. Running around like a headless chicken having a hissy fit, never got anyone out of the “merde”.
I’m sure this guy had more about him

The existence of this valve plus the inability of the OE glue and re-glue to hold is all very puzzling hence my saying the guy should put a picture up. Then we might come up with some *really* good ideas.

Wow ten potential valve issue locations on a 3m.

Doesnt particularly need to be a clamseal but something clamped either side with a rubber seal on the top side would probably seal it better than the glue hes pissing about with now. Even if he ruins the floor to the point he has to buy a new one hes 10k into a holiday being ruined by a boat that costs a few hundred to replace. I'm pretty sure if it was me I'd find some suitable plates & a bike inner tube as a gasket or epoxy to bond or such like & some bolts or screws to fasten the plates together far quicker than waiting another 3 days hoping the glue will hold after a 3rd try (which is highly unlikely now its been messed with so much). He could be back on the water in a few hours with some simple kit & a bit of ingenuity. Its easy to be negative & say stuff wont work but better to try & than not to try at all.

Yep time to start getting creative while he still has time to actually use the boat
