Unless you can sand off all your old glue down to bare tube rubber, I don't expect it to work.
It didn't, because of this ^ probably. I did use much less glue this time and left it overnight with a weight on it but it showed a slow bubble leak underwater
I replaced tube instead.
PITA these patches and tubes. Grease on my hands. I'm looking into tubeless or flat-free tires. I ride a mountain bike but might get a hybrid because I mostly ride in the street anyway. I just don't understand why flat-free tires haven't been used for decades, just give me a hard rubber tire and shocks to absorb everything and it should be fine, no? Or maybe tubeless like a car which rarely gets a flat but need a machine to break the glue seal.
Some cheap flat-free tires, some are pricey. I barely looked into it.
I put green slime in the tires too. I read mixed reviews but I don't think it'll hurt and I don't mind the extra weight of a few ounces and I have a giant tub of green slime I use in various yard machines.
Another things which strikes me as asinine is the rims are friction fitted to the frame, that is, the axle/bolt just gets placed into a slot on the frame and only the tightness of the nuts holds the wheel on! Not through-bolted. I assume better bikes are through-bolted. Remember this is a ~$100 Huffy but it's held up good actually. I am afraid the wheel will fall off so I tighten the F out of it with a ratchet and now I put a ratchet and socket in my bag because I used to only keep an adjustable wrench but it slips/strips sometimes when it's as tight as I made it now.
I did read about volcanized glue.. seems amazing, it can patch the SIDE of a car tire. Those 'rubber sticks' for car tires are volcanizing and I've installed ~10 in my life and never had a problem. I wonder if it'll be okay to put small amounts in plastic baggies or something then squeeze the air out and tie it so I can have small packets in my bag to patch while riding. Maybe they sell small tubes of it I will check and get that for sure. EDIT, they sell small tubes for $6 I might get a couple but it'd be smarter to just get a jar for at home and swap the tube while riding!
I save punctured tubes and patch 3 to 5 of them at once. That uses up a whole tube of glue. Old or opened glue tubes are usually dried up when I want to use them
I read an article said you should get 30-50 ! patches from 1 mini tube. They also said put tiny bit of glue on the patch. Seems like not enough glue. Says put thin as possible layer 3 times in a row. That's not a bad idea though come to think of it ... I can just keep a spare tube with me which I already do in case of a serious blow-out, and then I can patch the pin hole one when I get home and use volcanized glue. I won't be able to fully test the patched tube without riding on it but if it holds air after patched and inflated just the tube by itself for a day or so, that should mean it's reliable enough that if anything it might just have a pin hole which I can inflate as needed once I put that tube in the bag as the backup.
I don't like the metal rougheners, like a cheese grater. The small pieces of sandpaper in some kits are easier for me.
I agree, the cheese grater is as if in order to even scuff up the rubber I almost have to rip into it. I just put small pieces of sandpaper in my kit instead.
Never put glue on the patch. That foil gets peeled off, and I never touch the exposed surface of the patch. That exposed surface is made to bond to the dried glue on the tube.
True, the oils on fingers alone let alone the grease from the chain if it's the rear wheel really opposes glue. Another reason to just swap out tubes and fix it at home instead of patching while riding.
peel off plastic from patch and use lay patch directly over pea-size spot of vulcanising fluid and wiggle patch around to spread and smear.
that's smart^.
5. inflate tube to installed size,
so fully inflate it to ~40 psi BEFORE I put the patch on (but after the glue in on) ? Put the patch on it fully inflated and then vice it while fully inflated? sorry confused. OR installed size just means slightly inflated?
ordering vulcanizing stuff now. thanks!
