Mending punctures - Is it possible at 110 psi?

The other thing I have found is that once the seal is broken at the top of the tube of glue it has a finite life. After about a week or so it doesn't seem to work so well.

Hmmm. Interesting. Anyone else noticed this?

It crossed my mind, but never actually happened to me. That indicates a poorly sealed tube more than anything.

Many glue tubes are leaky and let the solvent content evaporate, leaving a useless gum. I've encountered plenty of (seal unbroken) old such tubes, which must have failed at the crimped end, never having been quite airtight after filling. It's problem enough that I've considered dipping new tubes in latex solution to attempt to seal them- but never got around to it.

To add support to the chorus of good advice, I leave a thin layer of glue at least a few minutes before applying the patch, and then leave the repaired tube overnight (no inflating/bits of wood!) before next use. The few hours' wait overnight is beneficial, as I showed to myself by trying to remove a just-applied patch, and then an identical one next morning. The first unpeeled, the second ripped through eventually, and was much more solidly adhered.

Nope.

Unless you're doing something silly like leaving the solution in direct sunlight or not ensuring the cap is air tight etc.

Seriously, get some TipTops and live the dream*














"Teh dream"
*repairing your inner tubes without planks of wood, vices, solution that goes off in a week, patches that fall off, patches that can't hold over 100psi and anything else you can dream of that hasn't yet been brought up.
