Guide to Low-Yellowing Epoxy for Outdoor Applications

Low-yellowing epoxy is a popular binder choice for colourful outdoor resin-bound surfaces, helping maintain the stunning look of pool surrounds and permeable floors over time. Here’s what to consider for long-lasting results in exposed environments.

Why Choose Low-Yellowing Epoxy?

Epoxy resins are valued for their strong adhesion and durability, but standard types can show noticeable yellowing when exposed to sunlight. Low-yellowing epoxy minimises this effect, making it a suitable binder for coloured stones on areas like paths, patios and especially pool surrounds. When using white or very light aggregates, however, non-yellowing polyurethane is often recommended for best clarity.

Practical Application Tips

For best results, choose a low-yellowing epoxy specifically designed for outdoor use and compatible with your chosen aggregate. Proper surface preparation—clean, dry and stable—is crucial. Pay attention to weather conditions, avoiding application during high humidity or temperature extremes, to ensure full curing and a robust finish. Many complete kits, such as the Flowstone Permeable Floor Kit, offer resin selection guidance based on your chosen stone colour.

When Low-Yellowing Epoxy Matters Most

Using low-yellowing epoxy is particularly important for maintaining the original tones of coloured stones exposed to sunlight, such as pool surrounds, decorative patios or footpaths. If you prioritise long-term colour retention in sun-exposed or high-traffic areas, this formulation is an ideal choice.
