Gah
If I see one more person using contact cement wrong, I'm gonna kick a kitten. This also includes Barge cement, common office-supply rubber cement, etc.
If you glop it on, join the parts together and wait for it to dry, you’re doing it wrong…you’re compromising the strength of the bond and wasting a lot of time as solvent tries to evaporate from between joined parts. Fine for Elmer’s glue, not fine for contact cement.
The correct method is to apply glue to both surfaces, wait for it to dry (sometimes repeat with a second coat), then join the parts. They lock together instantly on contact. This is why it’s called contact cement.
They put directions on the bottle, but apparently in my 46 years on this planet nobody has read them.
