Common Mistakes to Avoid When Storing Epoxy Resin

Q: Top Storage Mistakes to Watch Out For

Leaving Containers Open: Exposing epoxy resin to air can cause moisture contamination and affect the resin’s ability to cure smoothly. Exposing to Sunlight: Direct sunlight can degrade the resin and may cause premature yellowing or thickening, especially if left near windows or skylights. Damp or Fluctuating Temperatures: Storing resin in areas with high humidity or wide swings in temperature can lead to crystallisation or reduced shelf life.

What Are the Most Common Storage Mistakes with Epoxy Resin?

Proper storage is essential for maintaining the lifespan and performance of your epoxy resin. Avoiding a few common mistakes ensures your resin is always ready for your next creative or professional project.

Best Practices for Storing Epoxy Resin

To keep your resin in top condition, always reseal the bottles tightly as soon as you finish pouring. Store resin in a dry, shaded place where temperature remains fairly consistent – ideally between 15°C and 25°C. Cupboards, shelving units, or storage boxes away from heat sources work well.
For deeper pours such as resin tables, using products like “Epoxytable 10-Ten” Deep Pour Epoxy Resin ensures your work is supported by resin kept under ideal conditions.

Why These Details Matter for Your Projects

Maintaining correct storage preserves your resin’s clarity and flow, directly impacting project quality, whether for casting tables, river pours, or delicate craft work. Avoiding these mistakes helps ensure consistent curing and a professional finish every time.

When Extra Care Is Needed

If you buy resin in bulk for larger or infrequent projects, or if you work in outdoor or unheated studios, pay special attention to storage location and container sealing to protect your investment.
