pre Glued Patches......are they any good ?

[ianrauk]

The pre glued patch on my tube is now 18 months old. Runs at 110psi and is still fine.

I've had Park patches last at least 4 years on a tube before. And then the tube got replaced, not due to any failure. The only time I've ever had one fail is on one occasion when I haven't roughened up the rubber enough beforehand. As above, 110 psi or higher is fine, and so is CO2.

Using an instant patch is quicker, more effective, less messy and easier than the traditional glue and patch. If it's raining, then provided you can dry the area you're working on (which is where the sandpaper is useful to create friction), then the instant patch sticks fine, unlike glue which never sets properly when the air is very damp.

You have to apply them properly. Put one on without any preparation then they will fail. Prepare the tube as you would if using glue. Is rub down and clean the area. Apply the patch making sure there's no ridges with the patch. Pinch the patch and tube for a good 30 seconds until adhered. Do not inflate the tube outside of the tyre or the patch will lift. Done properly, patches last just as long as traditional glued patches.

So preparation is the key.

I use Halfords patches, and if done like this^^, no issues on either CX, road or Mtb.

If you're using them at home and not in an emergency on the road, cleaning the tube with meths or IPA is a good idea. Failing that a good lick will get the rubber pretty clean.

I only use them in an emergency if for some mental reason the spare tube also punctured.....they aint no substitute for a big slab of glue and a rubber patch...thats blatantly obvious when you look at them... someone will be along to tell me they got 5000 miles out of one however..

Is that all?
Try about 12000.

+1 to everything the blue man has said.

 

[MontyVeda]

Anybody that says to squeeze them and hold them and then to squeeze and hold them for a bit longer again, knows what they are talking about and should be listened to

my rule of thumb is hold it 'til thumb goes numb

I found that there must be no air in the tube so both patch and tube are in the most relaxed state, because the patch is designed to expand with the tube.

And do no inflate outside the tyre as Ian says.

Bet he wouldn't be so keen on Park patches if their brand colour was red.

Ian hit the nail on the head. You need to prepare the surface and apply them correctly.

Most of my bikes have Schwalbe Marathons and so punctures are not often a problem. But I did apply a ready gled patch last summer and the tyre is still fine.

If you get good tyres like Schwalbe and check them over occasionally, punctures almost become a thing of the past.

Now that 1st point is interesting. I assumed the opposite so "stretched" the tube over my wrist before I applied it.

I have them on MY bike but this is a loan/test bike.
