Thank you for your feedback.
With our glues, we would usually expect around 3 months or more once opened when they’re stored and handled correctly. Things like keeping them in a cool, dry place, sealing the nozzle properly, and minimising air exposure can all impact performance and longevity.
If you’d like, feel free to pop us a message and we can help troubleshoot what might have affected it for you we’re always happy to help.
