Puncture Repair is a Myth

i. Carry a spare tube and swap it straight in rather than doing roadside puncture repair.

1. At home with punctured tube, find the puncture and note its shape for clues as to cause.
   
2. Mark the puncture with a big cross (using the chalk - I use a pen or texta)
   
3. Assuming standard bit of glass, run your finger around the inside of the TYRE to find any sharp bits and remove them. If the puncture is on the inside of the tube, check for spokes sticking through rim tape, sharp rim tape edges, etc.
   
4. Get patch and note its size
   
5. Scuff area of puncture with sandpaper/scraper. Just rough it a little. I then wipe away any loose bits of rubber with my t-shirt.
   
6. Apply a circle of glue the same size or a bit larger than the patch you are using, centred on the hole. Apply it to the TYRE! You don't need heaps just make sure when you look at your glue circle there's no empty bits of just tyre poking through.
   
7. IMPORTANT! Let the glue dry a bit. The glue has to go off a bit. It should be quite tacky to touch and not still runny.
   
8. When you've left it long enough 2-10min depending on temp/conditions/how much you blow at it peel the backing off the patch and apply it.
   
9. Grip the fucker tight for a minute
   
10. Fit back onto wheel or wrap it up for later use.
