Topic tags/keywords: question gluing

Hi fellows,

I rescued an old can of contact cement from my basement and when opened it what I found was a thick contact cement jelly. I know I´d not be saving a fortune, but is it any way to bring that jelly into a fluid again? What should I add to it apart from thinner?

I’d just toss it.
You’ll spend more in solvent and time to try to get it usable again.

I don’t think that you can salvage it. If it were even to work I think it would leave a lumpy and/or uneven surface.

The glue has started to cure, a process you can’t reverse. So I won’t say what’s already been said a few times…...

You can get a thinner for contact cement that works reasonably well, but as NiteWalker said, it’s not worth the money or time to use it.

Read here:

If it’s not too far gone it can be rescued.

It depends on the price of replacing it. A quart of Barge (the
best stuff) is about $30.

I’d set it aside for shop projects that are less than critical, and buy a new can for your premium work.

I just used a thick and slightly lumpy bit in the bottom of an old can for a shop project and it came out fine.

Sure, you might be able to rescue this, but if you value your end product, I wouldn’t risk the failure of the adhesive when a few bucks gets a nice fresh can of reliable product.

It’s like assuming Jello will re-gel after you’ve re-liquified it.
There’s a chemical change that takes place when it gels—I can’t imagine that its going to be as good as the first time you put it in the fridge.

Thank you all guys!

I think my best bet is not using it… at least not for important projects… I still have some contact cement in good condition anyway :-) cheers,
