How do I prevent my resin frame from yellowing?

Yellowing is a common concern for anyone creating or displaying resin-framed mirrors. With the right resin choice and a few practical habits, you can keep your frame looking clear and vibrant for years to come.

Choose Epoxy with Built-In UV Protection

The most effective way to prevent yellowing is to start with a resin that features integrated UV filters. These filters help shield the resin from harmful ultraviolet rays, which are the primary cause of discolouration over time. Products like Trasparente Clear Epoxy Resin are designed with UV resistance in mind, making them well suited for use in decorative frames where exposure might be a concern. Selecting the right resin at the outset can mean significantly less colour change down the line.

Placement and Day-to-Day Care

Even with UV protection, behaviour matters. Position your mirror away from direct sunlight—such as opposite south-facing windows—or use curtains, blinds, or UV-filtering window film in bright rooms. If your frame is in a high-light area, rotate it periodically. For cleaning, opt for a soft cloth and gentle, non-abrasive products to maintain clarity and prevent micro-scratches that can accelerate visible ageing. Dusting regularly helps too.

When This Matters Most

Decorative mirrors exposed to regular daylight, especially near windows and conservatories.
Mirror frames in bathrooms or high humidity areas, as UV damage can be compounded by environmental factors.
Handmade gifts or bespoke furniture where long-lasting clarity is essential to value.
