I have taken some pics of my RIB. It's an Avon searider s4m, We have three of them. A picture is worth a thousand words. As you can see I have some delamination going on. I am not sure how I am going to attack the blisters.

Does all the advice still remain unchanged?

BTW we used this boat to help at a oil spill of Biodiesel. Biodiesel is a a powerful solvent and I cannot help but think that some of the Bio got on here and caused delamination.

I would consider thise areas small; slit the blistes and glue back. However, to prevent re occurance I would paint those areas with Tuff Coat.

I am in the process of tuff coating another RIB. Have you had any success with the product?

Advance apologies for hijacking the thread, I have a similar issue to the original poster.

We have a custom built 8.5m Scorpion RIB, we used a cheap plastic tarpaulin to cover it for a few days (combined with extreme heat) and on removal we've managed to tear away part of the Hypalon coating and suffered blistering in other areas. Because the boat is custom built, the manufacturers cannot perform the onsite retubing and sending the boat back to the UK isn't an option at the moment as we're in Africa.

Performing a patch repair is also not an option as it would be seriously detrimental to the appearance.

Thus we come down to performing a Hypalon repair; firstly is it possible to replace the hypalon on the tubes in situ? Then secondly can anyone recommend someone or a company who is capable of doing this?


Thanks

I'm no expert , but surely a patch done properly with suitable thought to the finished 'look' will be the best (and possible only ) solution - consideration of a suitable curve/ sweep back to the blue section - also in blue to make it look ' right' ?

This could be done anywhere in the world if you can get the material / glue to you ?

another solution is to use a hypalon paint, home-made !

You must get some "crude-hypalon" the color of your tube - or close ... and toluene.
It comes in flat block - I have some in light grey from Pennel and in red from Continental.

Then you should grind it to get a light powder.
Next step is to mix both - powder + toluene - and leave the solvent work.
Add some toluene to get a paint to be painted with a small brush.

The 1st layer will leave 1/10th mm, the next one ...
Leave it dry several hours, then add another layer, and so on !

Thanks yorfuoj, I've now had two people contact me via the website which I think will be very useful. Thank you for the help, would have a been a lot more difficult without www.rib.net.
Now looking into the liquid hypalon option.
