How do I prevent yellowing on a finished resin coating?

Select Coatings with UV Protection

The most effective way to limit yellowing is to choose a resin formulated with UV filters. For decorative and artistic surfaces, resins like Art Pro contain built-in UV resistance to provide longer-lasting clarity. Flexible coatings such as Heat Pro also offer UV protection, making them well-suited for surfaces that might be exposed to intermittent sunlight. These options form a bright, glass-like finish while guarding against the initial stages of yellowing.

Minimise Direct Sunlight Exposure

No matter how resistant the resin, ongoing exposure to strong sunlight can accelerate yellowing. Try to position finished objects away from constant direct sunlight when possible. Even with quality UV-stable coatings, keeping your resin works indoors or shielded will help preserve their appearance for longer periods.

When Prevention Matters Most

• For artwork or decorative items that are intended to remain clear or display vivid colours
• If you’re selling creations or gifting them, maintaining a professional-looking finish is essential
• On tabletops, trays, and coasters likely to face occasional sun or heat exposure
