Best way to repair PVC fabric

[ALEXSAILS]

Hi, this is my first post. Tons of opinions in the internet about how difficult it is to repair PVC fabric.

Im looking into buying a 11' dinghy inflatable but dont want to pay the higher price of hypalon.

Ive seen inflatables made with Strongman Duotex like some Zodiacs and 1100 Decitex (Dtex) plastomer PVC used in others.

Both are a a form of PVC and thermobonded at the factory right?

What is the best way to repair these PVC fabrics by gluing?
Which glue: (Clifton Urethane Adhesive, Stabond)?
Which fabric to use for repair?

thanks!

Hi and welcome to Ribnet. Do a search of the forums, the information you need is here. It was discussed a couple of weeks ago too.

The problem with PVC is that it is very difficult to repair a leaking seam (i.e. a weld that's gone bad.) Holes and small slits are not that big a deal, but seams are a problem. With hypalon, you can open the seam up to where you can effectively re-build it; with PVC that's not an option.

Good luck;

Sand it smooth and stick a patch onto it.

jwalker....
what do u mean by sanding sooth a seam??

how can this be done when its an overlapping seam (step in the material)???

thanks!

Just sand down the edge of the weld to feather it onto the lower level. Make sure it is feathered for a distance each side of the leak so the patch rests on good surface around the whole of the leaky area.

Similarly, you can feather the lower edge of the patch so that there isn't a step around the edge of it.

Good tip, if I ever end up with a PVC boat...

It works on waders, too.

I don't know how to quote a previous post yet, but we use the same procedure that jwalker describes. Also, make sure you have the correct adhesive that is based on polyurethane. Two part adhesive is best for long lasting, heat resistant bonds. Apply thin, evenly spread out coats of glue and don't try to rush the job.
