11. Don't Sniff The Glue
How To: Patches will work best on small holes. There are several kind of patches. Some are as simple as peeling off a sticker and placing it over the hole. For the old-fashioned rubber cement patch kits, here's what you do.
Rough up the area around the hole with some sandpaper (almost always include in bicycle patch kits). Clean the area and then put a thin coating of rubber cement glue around the hole. Make sure that the glue area is a bit bigger then your patch. Let the glue dry for a few minutes or until it's not gooey. Next, peel the backing off your patch and center if over the hole. Hold the patch firmly in place for at least a minute.
