Hypalon Patch repair

Hi all. Iíve successfully reglued various bits back onto my hypalon tubes over the years as edges have come loose etc.

Iíve tried 3 times now to glue a patch onto my tubes and Iíve failed every time. Iím using Rib Store Ďtoob bondí for hypalon and a some material that I bought a fair while ago Ďincase I ever needed ití. I canít remember where I bought it from but I would only have bought it if it was advertised as hypalon.

Each time the glue has bonded perfectly to my tubes but there is no adhesion to the patch at all. The patch literally peels straight off.

I canít tell the difference between PVC and hypalon, is it likely that the material is actually PVC and thatís why the glue is not adhering to the patch? Any other tips? Iíve watched many many videos and Iím following the steps precisely.

Hypalon should dull down when you sand it . PVC shows scratches on material.

The patch I’m using definitely gets dull as I sand it so it’s sounding like hypalon. Any ideas why the glue isn’t adhering to the patch then??

I'd suggest binning the unknown material & buying some new hypalon.

I tend to agree with paintman . You could try some acetone on boat first . I presume you are rounding corners on patch before sticking.

How does the patch material react to Acetone?
If it feels like the surface has almost melted and is very sticky it's more likely to be PVC.

If it turns out to be PVC it could still be used.

Follow the normal process for applying the patch with 2 stages of Glue etc, but use Hypalon Glue on the tube and PVC glue on the patch.
The two glues will stick together.
I've done this several times, although both Glues were made by the same manufacturer, IBS.

Thanks all, acetone doesn’t affect the patch at all, just cleans it. Definitely doesn’t go sticky.

All corners are rounded off too.

Buying new material was my first thought as well but wanted to check it was likely a material issue first before I did

I think these glues have a short shelf life once opened - that might be adding to the issues

Previous use of silicone based polishes and lubes can render tubes very difficult to glue. Have you sanded the entire area being covered by the patch? As mentioned ^ old glue is a no-no as well.

Update

Thanks to you all for your suggestions. I decided to buy a patch repair kit from Rib Store. The patch they supplied was identical to the material I had at home anyway but seeing’s as I now had a good amount of material, I decided to patch both inside and out.

Pleased to say that she has remained inflated for 48hrs so far with no obvious leaks, and with being subjected to temperature changes between 22 and 10 degrees.

I think new glue might have been the key factor but thanks again for your suggestions.
