A Guide to Low-Yellowing Epoxy for Outdoor Resin Applications

If you’re installing a resin bound surface outdoors, yellowing from sunlight is a key concern—especially for patios and decorative areas. Choosing the right binder is essential for both keeping your surface looking fresh and ensuring lasting performance.

What is Low-Yellowing Epoxy?

Low-yellowing epoxy is a specially formulated resin designed to resist discoloration from sunlight exposure. While all standard epoxy resins can gradually change colour when exposed to UV rays, low-yellowing varieties are improved for colour stability, making them more suitable for outdoor use on surfaces such as patios and pathways built with coloured stones.

When Should You Choose Low-Yellowing Epoxy?

A low-yellowing epoxy is best used when your paving involves coloured natural stones or aggregates, as it helps preserve their original appearance. In contrast, for very light or white stones, a non-yellowing polyurethane binder like Polirock is generally advised. For most other coloured aggregate surfaces, a low-yellowing epoxy ensures the overall tone remains vibrant for longer in the UK’s variable weather conditions.

Practical Guidance for Patio Installation

Before starting any resin paving project, always check your chosen product’s specifications and follow its application instructions. The Flowstone – Complete Permeable Floor Kit simplifies this process by providing clear recommendations: use low-yellowing epoxy for coloured stones, and opt for a polyurethane binder when using white aggregates. Ensure your surface is clean, dry, and free of loose materials before application to achieve the best, most durable result.

When This Matters Most

Choosing the correct binder matters in visible, decorative, and sun-exposed areas, such as patios or garden paths, where maintaining the look of your chosen stones is key to long-term satisfaction.
