Glueless / selfadhesive tube patches don't work for beans

[Veggie]

I've been using the regular rubber and cement type patches for years.

Recently, I tried out one of those pre-cemented patches. It was faster,
no glue drying time, etc. I had the tube back in there pretty quick.
The next morning, flat. I pulled the tube out again, pumped it up a
little and water tested it. No leaks! I changed the schrader valve,
pumped it up again. Flat within half an hour.

Must be one of those leaks that only happen under pressure. So I put
the tube in the tire, but leave it off the rim unmounted. I pumped it
up higher, since the tire is holding it back some. Sure enough, when
the tube is under some pressure and expands, the glueless patch scoots
moves ov a smidgen. Not a big deal, but air is oozing out too. I
reapplied another patch, located it a little to the side so that it
would be centered under pressure. Still leaks.

It seems to me that there is too much liquidy goopy glue on these
things. The glue never dries apparently, and air oozes thru it like air
bubbles in honey. Also, the patch itself is basically a thin piece of
green plastic. Too flimsy, should be a piece of rubber IMO. These look
like they would work on low pressure air mattresses or pool toys, but
not on bike tubes.

So do these new patches work for anybody? It's back to the old glue
patches for me, as soon as I figure out a solvent for the glue **** left
on my tube.

These are shite. You are not the first to report this here, and
probably not the last.

No, they are near useless, especially on road bikes. A shop owner told
me they are better on MTB tyres which are not too high a pressure, but
when I tried one it wouldnt stay on, so the pack I had went in the bin.

I use them. In my bike seat bag I carry a spare tube and some of the
Park patches. I use the spare tube for flats but if I happen to get two
flats in a day, I use the little quickie patches. Some have been in
place and working fine on road bike tubes at 120 psi for at least a
year. They seem to work best if the tube fits the tire, no stretching or
bunching.

That said, old fashioned cemented patches are better and I use them when
patching tubes at home.

They've worked fine for me over the past, not sure, maybe 5 years or so
they've been out? Maybe longer? Once in a while I get one that doesn't seem
to want to hold pressure over time, but I'm willing to put up with that
because I never have to worry about a tube of glue that has dried on its
own, rendering it completely useless. That, to me, is worse than a patch
that slowly leaks.

For what it's worth, the ones I use are from Trek, but look virtually
identical to the ones marketed by SCABS or something like that. Thin, red,
round. Not the square Park ones, which gave me (and many of my customers) a
lot of trouble. Maybe they've changed those by now.

What I found was that when they did fail, they left behind a residue that
prevented application of a conventional patch. Tried acetone and a couple
other things, but no-go.

I have been using the SCABS brand glueless patch for years. Every once
in a blue moon one may not hold. But I laways have several with me on a
ride so I can use another if needed. Proper care when applying helps.
The Parks brand never did work well for me. Taking the time on the raod
to use glue and such is a bit of trouble, and when you find the glue
has dried, well, you had wished you had a glueless one with you. I have
seen many a roadie cursing using glue kits when they have glue all over
the tube, tire, hands and still the patch fails. Glueless works for me.

Best answer is to carry a spare tube AND a standard patch kit. In
years and years of riding I have only ONCE needed the patch kit after
using the spare tube (knock on wood).

Glueless patches work for me, except when I'm not careful enough to
ensure a solid seal at that little mold ridge. Patches are my back-up,
if necessary, to the two spare tubes I carry, or for someone who needs
help but hasn't their own kit. (I'm always amazed at how many folks I
see on fancy bikes but no gear--pump, spare, etc. Isn't the joke that
the only equipment most people need to deal with a flat these days is a
cell phone?) Regards, Roy Zipris

To prevent this problem, buy only Michelin tubes, which have fewer and
smaller mold ridges than any other brand.

Also, a multi-blade safety razor head (Atra, etc) can be used to shave
them off. It's quicker and easier than sandpaper, and packs well in your
tool kit.

While older versions were suspect, I've had good luck with glueless
patches lately.

I think it's best not to inflate the tube to "test" the patch before
putting it into the tire.

I've found this too.

They may get you home. THEN, since they pull off so easily, you peel
them back off and put on a proper patch.

Dandy. I was going to take isopropyl alcohol, acetone or maybe paint
thinner to get the goopy glue off. I guess I shouldn't waste my time

Like many other stuff on usenet, people either have fantastic results or
complete failures. Kinda makes you wonder what the difference is, we
all did the old glue patches before so we all have some minimal level of
competence.

Another thing to ponder on those long uphill climbs...

Possible variables include

sanding off the surface layer on the tube, or not
patching over mold ridges
not enough pressure applied during application
inflating the freshly patched tube outside the tire.

If you're after insurance, use the patch kit first. That way you discover
it's dried out while you still have a tube.

I have seen claims that some have used them with success, but I have
yet to actually meet anyone who has been able to rely on them for more
than just the distance to the next air compressor. My own experience
led me to discard the rmeainders of the three packages I bought, and
(like you) resume using real patches.

Acetone worked for me; in areas where such solvents are not sold
openly, acetone can usually be obtained by buying nail polish remover,
but beware of the types that leave an oily residue.

I have had better luck with the self stick patches .If i cleaned the spot
with a Alco whip like for cleaning your glasses I get them from work .It
evaporates fast and the patch sticks for a while .
I have ridden ones for a whole weekend with hardly any air loss.I put a reg

When you put the regular patch on, do you just go right over the
self-adhesive patch's glue? Or do you remove it with acetone as another
poster mentioned?

go with superglue if no good contact cement is available using the
patch's unprepped side or maybe not that's under discussion. Wal is
selling superglue for $1 per fourpack card hereabouts. wal also sells
an auto patch tire kit and a four in hand valve tool over in auto
