PVC Tube materials

Hi everyone

After my rib has literally come appart at the seams, I am after some suppliers of materials.

Basically the internal seam material is a thin strip that I would like to upgrade for a wider piece if possible. Also the material that goes on the outside of the seam is very elasticated strip which will also need to be renewed.
If anyone can point me in the right direction it would be greatly appreciated.

In the pic the blue is the internal and the white the extenal.

In this instance, you might be better accepting this as a total loss, given it's PVC and source a new second-hand boat, or indeed a new one. The sort of repair that needs to be carried out is extensive. The rubbing strake goes on the outside after the internal seam is repaired. My concern would be trusting the repair afterwards. I've repaired top seams (under rowlocks) and on the cones on Zodiacs, but it was always contained to a specific area and wasn't as extensive as shown here. I'm assuming the 'solidified mess' is a rubberised solution that was used at some point to reduce air-loss?

You'll repair this, only for it to weaken elsewhere. If you're determined to repair - use 2-part PVC adhesive from Ploymarine.

Walk away would be my advice.

Yeah, I have found loads of expandable foam in the tubes, about 5 cans worth!! lol.

I intend to have a go at repairing the main seam, all the way round, thus hopefully eliminating any weak spots (I like a challenge), its finding the covering strips I am having trouble with. I would like a wider band on the inside then a new rubberised strip on the outside.
I am going to try the seam all the way round so that I can have a bash at the compartment chambers as these have also come unstuck. All the other joints are still solid as they have the same material on the joints as the tubes, but the main seam strip is pants.

I am sure there are some rib builders on here that can point me in the right direction.

Thanks for the advice but I do want to trying before admiting defeat. I unfortunately dont have the funds to buy a up together one.

.

You can also buy it from

http://www.ibs-boats.com/download/ib...talogue-08.pdf

and

www.polymarine.com/


you can fix it but it's trickier to glue than Hypalon and the glue is much more of a problem if inhaled, It's not a nice buzz at all, unless you are from Devon!

You can buy pvc strake from Wilks Rubber.. At least, you used to be able to. Polymarine can sell you pvc fabric as well as adhesive. Do a ribnet search for how to do the glueing.

Thanks everyone, that first link for the seam tape is spot on. I called polymarine yesterday and they were not very helpful and said I would have to go manufacturer for the seam tape.
The glue looks spot on though.
No worries about the fumes, my head spins out anyway and I live only 45 mins from devon!! lol
