Stone Fix after expiration date can still be used if it retains its bonding properties. Adhesives of this type may gradually lose effectiveness over time, which is why the shelf life is relatively short. If only a short time has passed since the expiration date, and the product looks normal and begins to harden properly after mixing, it may still be usable. However, using the product beyond its expiration is at the aquarist’s own risk. As the manufacturer only guarantees performance within the specified date.
