how do I refresh contact cement

why you asked in this group i can't figure out, but a little bit of acetone will work.

There's real big difference between "contact" cement and "rubber" cement. Contact cement is what you use to adhere Formica to wood to make counter tops. I hardly imagine you'd be using that to adhere a pattern to glass. And, rubber cement is so cheap, why would you want to waste the time to re-disolve any that had dried up? Just chunk it and open a new bottle.

yep,

contact cement is basically for laminates......smear one side of each unit, position it CAREFULLY and stick together

rubber cement is for a "temporary" adhesion and removable

M is right.......buy some new stuff..keep it TIGHTLY closed

You are right...first, it was the rubber cement I was inquiring about, I should of been more specific. Secondly, I have three full bottles of the rubber cement which are rather stiff and wanted to know if there was some way that I can "refresh" the glue.

Thanks to all that offered help!

Naptha gas (camp stove fuel) will thin rubber cement.

yeah, toluene is the ingredient in glues that gets one high if sniffed. Working with that may be more than you bargained for! m
