patching tires
 

the instructions where not clear. do i let the glue dry first before puting on patch

Patchin inner tubes
ID hole, mark with cross-hairs if needed.
Roughen surface with sandpaper, for adhesion. Wipe clean.
Smear thin film of rubber solution larger than patch.
Wait until tacky; a bit dry but with some grab. Test it out on a spare inner.
Some people add another layer of rubber solution and wait till tacky.
Apply patch, pressing from centre outwards to exclude air.
Crease patch to break film or foil. Peel film from centre, outwards. NOT from edge, inwards.
Some people rub chalk dust over remaining tacky rubber to prevent sticking to tyre. I don't.

Patches with feathered of bevelled edges are best.

Roughening the surface removes the layer of oxidized rubber and parting compound from the surface to allow a chemical bond to the patch, so don't under-do it. I use acetone at home and an alcohol wipe on the road to be sure any oils or waxes are removed. Roughen/clean an area larger than the patch and apply plenty of vulcanizing fluid to the entire area. Let the vulcanizing fluid (not really a glue) dry naturally, don't blow on it. Don't touch the tube or patch bonding areas with your fingers. Use the narrow edge of a coin, wrench or tire lever to "stitch" the patch down, especially the edges, for good adhesion; pressing with your fingers is not enough pressure to ensure a solid void-free bond.

I usually wait 30 sec. - 1 minute before putting on the patch.

The instructions on my patch kit say to wait 5 minutes so I wait 5 minutes. I always carry a spare tube (or 2) with me so I do my patching in the comfort of my workshop and waiting 5 full minutes isn't a big deal.
