Cement turned black

[Alden Cole]

My contact cement has gone stiff (jiggly) and black. I added thinner, but nothing is happening. Is this a common problem? Any help appreciated.

If the can is old, then yes, this is normal. I have gotten away from buying cement in those style of cans for that very reason.

Thank you. I put a lot more thinner in, and was able to get some usable cement in there, but it is still dark and thick. Maybe I'll put even more thinner in and see what happens. What type of cement do you use?

Good morning, Alden. I now use Weldwood contact cement on suggestions from another forum (I think). It comes in a standard paint can that seals good.

Thank you!
