How can I prevent yellowing of resin in wood projects?

Yellowing is a common concern when using resin in wood projects, especially for items designed to last. With a few practical steps, you can help keep your resin pieces looking clear and vibrant for years to come.

Choose UV-Resistant Epoxy

Not all resins are created equal — for wood and resin projects, always look for epoxies formulated with robust UV filters. Products like EpoxyTable 5-Five offer strong UV resistance, helping to maintain a non-yellowing, clear finish over time. For even deeper pours or larger projects, consider resins such as “Epoxytable 10-Ten”, which are also designed with non-yellowing properties in mind.

Protect from Sunlight and Heat

Once your resin and wood project is complete, where you place it can significantly impact long-term clarity. Try to keep the finished piece out of continuous direct sunlight, as intense UV exposure accelerates discolouration. If your design allows, positioning items away from windows or using protective coverings will help ensure a longer life for the resin’s clarity.

Practical Application Tips

Work in a shaded area or indoors whenever possible.
Allow resin to cure fully as per the manufacturer’s guidelines before exposing to light.
For tables and decorative items, occasional use of UV-protective waxes or polishes can offer additional protection.

When This Matters

Taking steps to prevent yellowing is most important for pieces placed in well-lit rooms, on display tables, or intended as long-term centrepieces. It’s crucial for both aesthetic and resale value.
