Hi, i just bought a zodiac mk 3 GR model 3432 from year 1986. I wonder if it is hypalon or pvc? All the seams are overlapped and glued. When i look inside thru the valve i only see white. I have been told that you cant use same glue for hypalon and pvc. Can some one please help me
Hypalon & PVC are very different to repair. With hypalon simply mark out & prepare tube & patch or seam & seam. Try to carry out in warm weather or indoors. If not its a heat gun warm up. Apply 2 layers of glue with the correct amount of hardener. Thinning glue down gives a more even coating. Glue has to be touch dry before adding another coat or sticking together. Drill & flap wheel is best for preparation. Don't go too deep or you will see fabric and that's not good.
PVC is different in that preparation is with sandpaper & hand. Power tools melt the material. Before you apply glue use thinners on the material and between each layer as glue needs to be slightly tacky when coating or preparing to stick. The clever way to know when it's ready is to touch the glued surface with a latex glove. If your finger ends up 8" from the material and the glove is still on the glue. It's ready. To wet or too dry and it won't stick. The glue will bite into the fabric over a few days.
i just got a noaa zodiac grand raid mk3 boat in for repair and it was one of a very few that were pvc.
just take it in to your local shop if you still have any worries,they should be able to tell or just post up a good pic.
the grand raid was made only in hypalon-neoprene, it's a work boat and all of zodiac's work boats or commercial grade were hypalon over neo
Is there any hypalon that is not over neoprene? As far as I know all hypalon material is hypalon exterior bonded to a neoprene lining with polyester fabric in between?
