Sure fire tube patching 101.

1. Rough up area over hole.
2. Clean with alcohol to remove any oils. (Hypodermic prep swabs work great for this)
3. Apply vulcanizing glue to area greater than patch.
4. Allow to completely dry for 5 mins. (most important step)
5. Apply patch and press firmly in to glue.

Never had a patch fail.

I tend to go like this.

1. Remove tube, look for hole

2. Inflate tube, find hole.

3. Deflate tube, get glue, lose hole repeat steps 1 & 2

I think step 1 is just as important as step 4. I've never done the alcohol rub thing and have never
had a patch fail.

2.5 Mark hole with a pen. If you're on the road and can't find anything to mark the hole, tie a knot
just below it.

Good advice from all re: how to patch a punctured tire.

But, I advise not patching it beside the road in the first place. It takes too long, and it's
sometimes difficult to find/mark the actual site of the puncture.

Better by far (IMHO), is to carry a spare tube in a zip-lock baggie with some talcum powder thrown
into it. Then, all you need to do is check the inside of your tire to make sure you don't still have
some glass or a thorn embedded in it, replace the old tube with the new one, and you are good to go.

Patching a tire at home, rather than beside the road, is much less aggravating.

Note: you'll still need to carry a patch kit, in case you get a second flat (rare, but it happens).

You're probably right there too. I just do the alcohol thing because it makes the patch area nice
and clean.

Mike - and I kinda like the smell. ;^)

There's a danger of ripping the tube (parts of the patch may have bonded). It's better just add some
more cement to the bits that are peeling up, allow to dry, then press down again. But if that's not
feasible, then try and remove patch or cut your losses and throw away tube.

I'm not sure you need to, but sanding will do.

I usually carry 2 tubes, but I have gotten 4 flats on an all day ride. I always carry a patch kit
with me on the road for those, hopefully rare, days.

There's more in there than you may first suspect. I think knowing why things work or don't work is
more important than to follow a rote recipe.

Sometimes I can peel the leaking patch off, but most of the time some part of the patch
really-really sticks and the tube tears. If it comes off cleanly I have re-patched them. If I have
one of the slow bubble things working it's way out from the side of the patch I have simply stuck
another patch over that part (you oughta see some of my tubes :-)

I think this is in the FAQ, but if you carry an extra tube you can avoid patching on the road,
which is qood. Then, when you get home you can patch the tube under nice conditions and give the
glue about 24 hours to set up (that is the FAQ portion, writen I think by Mr. Brandt). It's a
good system.

You HAVE to really rough up the area to be glued (see the FAQ) and you also must allow the glue time
to dry (as has been mentioned) before applying the patch. I use my watch to be sure I let it dry for
at least 5 minutes, especially when outside under adverse conditions where I am tempted to push the
limits. Sticking to all these things has reduced my patch failure substantially. I suspect it is
even more important to rough up the tube well when using the "instant" or "no glue" patches.

It helps to use a biro or whatever to mark the hole with 'cross hairs' so that you can find it again
once all the prepping is done.

As was mentioned, after a day or so the patch, at least that part that did not separate, cannot be
removed. That is how well these patches stick if you don't try to ride on a freshly patched tube.

Roughing up is not the goal as others who use solvents have mentioned. The purpose of the sand paper
in the patch kit is to remove the skin of the tube that contains mold release from manufacture.
That's why a piece of 1" wide fairly fine belt sander belt is ideal. Those cheese graters on some
auto patch kits were made by people who had no idea what their forebears had intended when they made
fine fine cheese graters. These guys thought they were doing the customer a favor. It's amazing how
such things get lost if you don't write them on the package or in a book.

Not necessary. On a dry hot day the glue is dry after no more than 30sec while on a cold dank
day it may take more than a minute, but you can see that. There should be no liquid/gelled glue
on the tube.

That sounds pretty sticky, the tube stuck to all these things...

It can be done more simply, if the leak is really so small the hole can't be seen. To find the hole,
inflate the tube to about twice its natural size and run it past our open mouth. Even a tiny jet of
air is detectable that way. When found, sand at that place with the tube inflated and apply glue.
Even a small hole will make a tiny white bubble. After it dries, let the air out and put the patch
in place. The glue dries faster on a stretched tube anyway.

Sometimes you think that the "object" that caused the flat came out, but it's really still in a
thicker part of the tread or on an angle so that it pushes in sometimes, but you can't feel it in
the tire. I always find the hole and use the hole to know where in the tire to check (2 places in
case I get the tube turned around 🙂). I always put my tire on with the label opposite the valve to
make this easier -- I don't have to remember the tire's orientation.

I'm one of the "carry a spare tube" kinda riders. Much faster to pull out a new tube and install
without patching the old one first. Consideration for riding buddies being foremost on my list.
Noone likes to stand around on the side of a road watching glue dry.

On top of the tube, I carry one of the "instant patch kits" from Park. If you have a second flat,
you can patch the first tube while it is off the bike, install, and be on your way again quickly. A
word of warning about the instant patches: they are not permanent. You'll need to break out the old
fashioned glue patches when you are back in the comfort of your garage.

I've used patches to reinforce holes in tires where I've picked up nails, etc. so the tube
doesn't bulge out of the tire. Beats either waiting for someone to come get you, or walking back
to the vehicles.

Tell Peter Noone to stop watching the glue dry, and sing a song with the Hermits. ;->

My patching regime would eliminate step 2, and add step 3.1 and 3.2, which are:

3.1 Allow to completely dry for 15 mins.
4.2 Apply more vulcanizing glue to area greater than patch.

I read somewhere years ago that this makes a more secure patch and do it if I have time, like when
I'm patching a tube at home. When on the road I eliminate the added coat of glue.

I'm not at all sure if the added coat actually improves things, but it works for me. We all have our
little quirks and I don't tie and solder my spokes. :-)

Thanks to all who offered their experience and knowledge. I repatched the tube, this time waiting
patiently for the glue to dry, and the patch appears to have held. Lesson reinforced. --Roy Zipris
