Is it really impossible to get a good glue bond between a hypalon patch and the exposed inner hypalon fabric? I don't have as much experience with hypalon, but have bonded patches to chafed tubes on hypalon river rafts (they didn't look as bad as the 470 floor material).

I would clean off the floor material carefully and glue the speed tube case seams down. Any exposed hypalon exposed fabric that isn't covered should be patched or sealed with a liquid rubber coating like SRC. Maybe I've gotten away with this type of bond because they were just wear patches and not a structural bond like the speed tube seams are?

It appears in the pictures of the damage that the hypalon floor to tube seam is unbonded and the hypalon surface is intact. It is the speed tube casing to floor seam that is so bad. Will Buckley470 really have to replace the floor material and speed tube casing to get a good bond?

I get a good bond to small areas of damaged fabric on my PVC boat, but that is a different fabric material and not so extensively delaminated. Anyone have some recommendations?

Buckley- by the looks of the photos I am gonna go out on a limb and say that is not the first time that this happens on that boat. From the photos it looks like heavy glue in some areas as if a repair was previously done. Gonna be a very tough repair to attempt .

You can sometimes get a good bond where it's gone down to the weave, just lightly sand it, wipe it down and then give it a priming coat of glue and leave it for a day or 2, then proceed as normal.

If it does hold but you're not 100% happy could always then run another strip over the top with a 1 inch overlap to hold it down

I think if I were to tackle that job I would remove the speed tubes for good. You would still have a decent boat equivalent to a Classic or Grand Raid.
