Preventing Yellowing in Resin Shower Trays

Yellowing is a common concern for those installing resin shower trays, particularly in bright bathrooms or when seeking a pristine look over time. Understanding how to minimise discolouration is key to achieving a lasting, crystal clear finish.

Choose UV-Resistant Epoxy Resins

UV light is one of the main culprits behind yellowing in resin trays. Look for epoxy resins that are formulated with strong UV filters and marketed as non-yellowing. For example, Epoxytable 10-Ten features integrated UV resistance, offering long-lasting clarity. For thinner pours or top coats, products such as “Trasparente” with built-in UV protection are also suitable.

Smart Curing and Application Tips

Yellowing can result not just from light, but also from excess heat during the curing process. To prevent overheating, never pour resin thicker than the recommended depth for your product in a single go—layer large volumes and allow at least several hours of curing between pours. Avoid direct exposure to sunlight while curing and steer clear of heat guns or accelerated drying methods.

When This Matters

If your shower tray is positioned under a skylight or direct window, selecting a high-quality, UV-resistant epoxy is especially important.
In bathrooms with strong indoor lighting or a predominantly white design, even minor yellowing can become more noticeable, making product selection crucial.
