    Default Lifespan - can of Mastik glue

    Starting to glue my own tubulars for every day use (after 20 years of 'clinchers are my life' and paying someone to glue my race wheels). I don't anticipate doing large volumes - probably 4-5 tires a year. How long does a well-sealed can of Mastik last ? Doe it dry up ?

    Yes, the solvent evaporates rapidly.

    I use tubes because I don't have to fool around with re-thinning the glue when the solvent evaporates. Also, tubes are handy AND I really do not love the smell of a open can of glue.

    Agreed, the tubes are the way to go. I actually don't even use a can for shop use. The tubes are cleaner and the smell from an open can is not something I can deal with.

    If you are glueing new cyclocross tires and doing all the layers needed for a roll-proof job, you probably will go thorough an entire can of mastic for 4-5 tires.
    If the can of mastic does thicken up a bit, you can add a bit of solvent to thin it back out again. Hexane is the solvent that mastic is formulated with. If you cannot find pure hexane, I have used small amount of acetone for thinning but Acetone is a much higher polarity solvent than hexane and will cause the mastic to precipitate into a tarball if you mix in too much. I just wouldnt use paint thinner which is likely too greasy and may effect the bond strength.
    Use a hammer to firmly seal the lid of the can back down after use and evaporation will not be too much of a problem.

    a year of non use useless
    6 months close to useless

    no way no how are you going use a can for 4-5 that is a recipe for failure too much glue is as bad as not enough the tire peels off the same under riding conditions

    one tube does a decent pro glue job
    one and a half tubes does a great consumer glue job

    Chuck Norris is expected to win gold in every swimming competition at the 2008 Beijing Olympics, even though Chuck Norris does not swim. This is because when Chuck Norris enters the water, the water gets out of his way and Chuck Norris simply walks across the pool floor.

    Likewise. With a tube you know it's fresh and someone's tubular won't roll off.

    Yes but it isn't the glue's problem if you know what I mean. Too much of a good thing... :)
