How to Prevent Yellowing in Resin Pools

Yellowing is a common concern when working with resin pools, as exposure to sunlight and environmental factors can alter clarity over time. Choosing the right materials is key to maintaining a long-lasting, clear finish.

Why Does Resin Yellow and How Can You Prevent It?

Resin pools may yellow due to prolonged ultraviolet (UV) light exposure or heat. To limit yellowing, always select resins formulated with robust UV filters. These additives help shield the cured resin from the sun’s rays, preserving the material’s original clarity and colour.

Features That Minimise Yellowing

UV Protection: Opt for products that specifically advertise strong UV filters. For example, Epoxytable 10-Ten includes robust UV protection and offers a guarantee against yellowing for several years.
Anti-Yellowing Warranties: Top-tier resins often provide warranties (commonly 5 to 10 years) covering yellowing, which reflect confidence in the product’s longevity.
Quality Formulation: Premium resins, such as “Art Pro Deluxe”, feature advanced chemistry for increased resistance to discolouration and surface deterioration.

Practical Tips for Application and Care

When preparing a resin pool, apply resin in the recommended thickness and follow the manufacturer’s instructions regarding curing times and environmental conditions. Limit prolonged exposure to direct sunlight wherever possible, even if the product is UV resistant, and keep the surface clean and free from chemical contaminants to further protect against yellowing.

When This Matters Most

UV-resistant, anti-yellowing resin is especially important for projects exposed to sunlight or used as surface coatings in water features and decorative pool areas, where clarity and appearance are critical over time.
