EXPIRED HARD SHELLACubeaut
Email from Nick 12th Dec 2022
I have some hard shellac with an expiry date November. You say after the expiry date it won’t be much use’. I’ve tried some test patches, and it dries normally, doesn’t stay sticky. Do you think I can go on using it, or does the ‘cross linking’ with the additives stop working even if it applies ok?
I will get a new bottle anyway! But it’s not that easy to get here in the UK, my supplier is waiting for a new batch.

We give it 18 mths shelf life but have heard of it still working the same after 3 years and up to 5 years so I guess you can just keep on keeping on.
Problem with regular shellac is that after it’s expiry date it will never fully harden. However, it appears that the hardener seems to get around that problem somewhat.
Hope this is of some help to you.
