  • You don't really need it to be that tacky when you mount the tyre. It's contact cement so will bond once it's in contact, regardless of whether the glue is wet or dry. The problem is more the bond between glue and wheel or glue and tyre.

    The bond is always basetape to rim and basetape to tyre. The bond is created by, resp., mastic and contact cement. The bond rim to basetape is elastic and "sticky" and the bond basetape to tyre is non-sticky. That is why one needs to choose cements to attach basetape to rim that are less "strong" than used to attach the basetape to tyre to prevent basetape seperation. The strength is the weakest of the two. Since the road mastic (cement) used to attach basetape to rim is intentionally "sticky" by design it means that the bond can be rebuilt. That is why one does not need the glue to be wet. A little bit of heat from braking will soften the road mastic and the pressure of the inflated tyre will create a very good contact bond. Track technique is, however, quite different as one uses non-sticky hardening cements (shellac or industrial cements such as Terokal 2444) whose bonds once broken are broken--- similar to the bound between the basetape and tyre.
    NOTE: note all cements are good for attaching basetapes to tyres. While latex glues work well with cotton and silk tyres they are suboptimal with nylon. Other contact cements are better choices--- Terokal, Patex etc.
