Thanks! great info. Used to patching butyl tubes, you need to wait till the cement feels dry to to the touch, while with Tubolito instructions you just wait 1 minute, but the minute will vary with the amount of glue, air temperature, etc, and if I wait too long with Tubolito, it does not glue at all, its hard to wait too long with butyl, patches fail to stick more often if you wait too little than if you wait too long. So my question is how long do you leave the glue to set before applying the patch, and how do you know you have waited enough?
@@martinaboitiz9600 As you would in solvent welding PVC pipe, put it together wet, hold under light pressure for perhaps 1 hour, and let dry a day before use. Patch material is easier to handle if it is placed on a bit of masking tape.
I used some tpu glue (branded tpu glue but it seemed more like super glue) but it didn't seal. Maybe my mistake was to use the Cyclami supplied patches that already have some glue on them. Doesn't the preapplied glue on the patches interfere with the glue you're adding on? Also, has anybody figured out what this tpu glue actually is? Thanks.
Yes! It is a solvent, commonly available as PVC cement as a plumbing supply. The active solvent is TetrahydroFuran. And yes, the contact adhesive on the "instant" patches needs to be cleaned off before attempting an adhesive repair. Alcohol softens the contact cement. When coated with the PVC cement, the patch material becomes very soft and hard to handle, but if the patch is held on a bit of masking tape it's better.
@markfisher7962 Awesome. I'll try pvc cement then. I haven't had much luck with the regular rubber cements, even though I did initially get the tubes to hold air for a few days. It was a weak bond and the patch came off after pumping the tire a few times. The stretching of the patch area eventually damages the "bond" between. And this is after clamping the thing all night. I did use tube pieces as patches and not the supplied patches. Actually you can use the band that holds a new tpu tube together. It is just a piece of tpu tube. Cut a patch from that.
@@mikeh6286 I followed the standard PVC procedure: clean and prime with Oatley primer, position patch on masking tape, using a small brush for control, coat surfaces, hold under a weighted foam pad for ~1 hour, remove masking tape and let dry ~1 day before use.
You got the same weird deformation of the TPU tube I did. Thanks for double glue suggestion.
Thanks for sharing your experience
Welcome 🤜🤛
I died. I know it has been mentioned before. I ride this tube with 4 patches. He says it so proudly.
Thank you, informative video👍

Four patches on one tube! Sounds like something I would do 😂
Even with four spare tubes, the temptation to first try four patches is too strong 😂👍
i had 6 patches on one of mine, but it holds air only 24h :)

Don’t bother just replace with a new one they are as cheap as chips
Tubolito tubes are $30 each.
@@LeifWarner the knockoffs are $8.50 each. Still worth patching!
Talk too much
