Low-Yellowing Epoxy for Outdoor Permeable Flooring

If you’re planning to install an attractive resin-bound permeable floor outdoors, you may have encountered the term “low-yellowing epoxy.” Understanding its purpose helps you keep outdoor surfaces vibrant and looking new for years to come.

What Is Low-Yellowing Epoxy?

Low-yellowing epoxy is a specialist resin designed to resist the gradual discolouration—or yellowing—that can occur when standard epoxies are exposed to sunlight. While all epoxies eventually show some ageing, low-yellowing formulations specifically help floors with coloured stones remain true to their original hue for longer, supporting both aesthetics and functionality.

Where and Why Should You Use It?

Low-yellowing epoxy is best suited for outdoor installations that use coloured aggregates—think patios, driveways, and walkways featuring natural pebbles or decorative stones. If you’re using white or very light aggregates, a non-yellowing polyurethane resin is often preferred. For most coloured stones, however, low-yellowing epoxy balances clarity, strength, and cost-effectiveness.

The Flowstone Complete Permeable Floor Kit includes guidance on when to use low-yellowing epoxy versus other resins, ensuring you get the right finish for your project.

When This Matters

If you want your coloured permeable floor to stay vibrant and withstand the British weather, particularly in sunny or exposed areas, choosing a low-yellowing epoxy binder will help maintain lasting kerb appeal and minimise long-term discolouration.
