Tube Patch Vuccaanizing Cement

Is there any way to prevent the vulcanizing cement in tube patch kits from evaporating after being opened??
I must have 3 dozen orphaned patches as every time I open up a tube of cement, it is useless at a later date.
and, purchasing the cement alone is more expensive than buying patch kits.

Go figure................

You could put vaseline/grease around the threads to kinda seal out air, but then there is the issue of contamination of the cement by the grease. The best solution I've read is to save all your punctured tubes until you have enough to use one tube of cement at once. That is how I currently roll.

I try to push out the air in the cement tube then recap it. It helps a little. If you go to the auto parts store you can pick up a patch kit fairly cheap with a slightly larger cement tube.

I did kind of the opposite. I got a bunch of the smallest ones I could find on ebay so if it dries up after one use, no big deal. You can keep several in your saddle bag without using up much room.

You can buy a bunch of small tubes of cement inexpensively, on EBay and elsewhere on the Web, to use the orphaned patches. Or just save a bunch of tubes and patch them all at once.

The small tubes included in patch kits seem to be far more susceptible to drying out than the larger tubes that you buy separately. I bought multiple large tubes from amazon, and I'm still using the first one that I opened, after a year or two and LOTS of tube repairs. Sure, keep one or two of the tiny tubes in your saddle bag patch kit (if you carry one) but for home repairs, get yourself a larger tube. I don't remember them being very expensive at all.

I throw a spare tube in on the road and patch them at home. I buy 8 oz cans for home use at the auto parts store. LBS is not the place to buy patch kits except for small ones for in my bag. Slime/Rubber Cement 1050 at AutoZone.com

Look on ebay. You can get little tubes of patch glue for very cheap. Took about 1.5 weeks to get it the last time I ordered. There are suppliers of the exact same item on Amazon as well.

[edit]: didn't see that this has already been suggested

To the point of your question. I've had a bunch that never evaporated and I was actually able to use the complete tube worth of glue. I've had others that evaporate. I "think" I tighten the cap equally well on all of them, but don't know for sure.

+1
Push enough that you actually have a bit of glue coming out and then screw on the cap. It makes a world of difference.

Looks like batch repairs and a larger tube of cement for the shop are god answers.
I'll pick up some small tubes for carrying wit the patch kits on my bikes.

Thanks!

There was another thread about using Elmer's Rubber Cement recently, so that's another option.

I keep unopened tubes of cement in my patch kits since I have never really patched out on the road. I'm going to pick up a container of rubber cement for home use; just haven't had to patch anything in quite awhile to force me into it.

Go to an auto supply store such as O'Reillys or similar. The sell cold-vulcanizing fluid which is the same stuff as in the little 5 gram Rema tubes, in 1 oz tubes for under $3, or in 8 ounce cans for about $8. X-Tra Seal is one brand, I'm sure there are others.

I reserve the Rema kit for garage use and carry glueless patches as a backup to my spare tube. My family must get a lot of flat tires because I find I run out of patches before I use up the cement so I have 2 or 3 unopened tubes and I end up buying loose patches to restock my kit.
That said the glue usually stays good for up to a year but my summers aren't very hot.

I always squeeze the tube just enough to bring the cement up to the tip of the tube and then cap it right there. The less air you have in the tube of cement, the longer the cement will last.

I carry a spare tube, and a brand new patch kit. If I have an opened patch kit, I have that too. When I flat, I put the spare tube in, and patch the flat tube when I get to home or work. (I have jars of cement and plenty of patches both places.) I use the patch kit for a second flat, to lend someone, etc. That way, in the unlikely event I need a patch on the road, I know I've got something that will work.

I have to say, though, that modern flat resistant tires are getting really good, and flat very rarely these days.
