I've personally never ridden on Latex inner tubes.

If I get a puncture on a latex tube I'd prefer to be able to fix it, given they're a lot more expensive than regular butyl tubes.

My research suggests

  • No, nothing works, you need to replace the whole tube whenever it punctures
  • No, but you can knot them to isolate the hole and then reinflate for the ride home, where you replace the tube.

and

  • Yes, with regular tyre patches and vulcanising fluid,
  • Yes, with regular tyre patches and rubber cement
  • Yes, with latex patches cut from another latex tube, and rubber cement
  • Yes, pre-glued patches (ie "stickers")

But for everyone claiming one of the solutions works, someone else says that it doesn't work.

Is it possible to Patch a puncture on a latex inner tube? and is the patch permanent or only a get-home fix ?

  • Probably best to leave tubulars out of this, and focus only on latex innertubes. – Criggie May 29 at 2:48

    I can only answer a couple of those: yes, with regular tyre patches and vulcanising fluid; and, yes, with regular tyre patches and "rubber cement" (as in this: amazon.com/Slime-1050-Rubber-Cement-oz/dp/B07H8RLF9G). I've never used pre-glued patches on a latex tube, and I haven't tried latex patches cut from another latex tube so I don't know if they'll work -- but I suspect that they will. Next time I get a flat I'll try and revisit your question. – R. Chung May 29 at 4:12

    @R.Chung that looks like an answer right there (even if it doesn't address every point). – FreeMan May 29 at 16:14

    Semi-related: @RoboKaren asked in 2015 if rubber cement (e.g. the kind you can buy at the store) was the same as vulcanizing fluid. Some debate here: bicycles.stackexchange.com/questions/35317/… but, contradicting that answer, one other chemist said that they seem to be identical bikeforums.net/road-cycling/… – Weiwen Ng May 29 at 19:00

    It's possible that a lot of the people that claim method's a, b and c work are only inflating to 70psi or lower, but if they were to inflate to 105psi or higher then they'd understand that their chosen method doesn't work... Friend claimed those Leyzene glueless patches were the duck's nuts, so I used them, it was a hot day, tube literally popped on me at the lights when I (randomly) stopped with the patch on the pavement... Turns out she only pumped to about 60psi and here I as going near double that (not latex, but similar logic applies) – Lamar Latrell May 31 at 1:10

It is possible to fix both latex intertubes for clincher tyres and latex inner tubes inside tubular tyres.

Whether you'll be able to do it, depends on your ability to do it.

As you suggest, using a patch made from another latex tube and glue will work. This webpage suggests using tubular rim glue instead of normal patch glue for better results.

That webpage also gives detailed instructions on how to mend a punctured tubular tire.
