Epoxy can go bad or degrade over time, especially if it’s not stored properly. Unmixed resin and hardener can have a shelf life, typically ranging from 6 months to a few years, depending on the brand and storage conditions.

Signs of bad epoxy include crystallization, yellowing, or a thick, uneven consistency. It’s important to store epoxy in a cool, dry place and tightly seal the containers to extend its shelf life. Using epoxy past its prime can result in poor curing and performance.

Our Superclear Epoxy products come with specific storage instructions to maintain their quality.
