What Is Low-Yellowing Epoxy and When Should You Use It?

← Back to Permeable Flooring vs Concrete – Which is Best for Your Project?

When working with resin-bound surfaces, the appearance and longevity of your installation can depend on the type of epoxy binder used. Low-yellowing epoxy is a popular choice for projects where maintaining colour clarity under sunlight is crucial. This guide explains what low-yellowing epoxy is, its common uses, and how to choose the right resin for your permeable flooring project.

What Does Low-Yellowing Epoxy Actually Mean?

Low-yellowing epoxy refers to resins formulated to better resist the gradual discolouration that can happen when exposed to UV light. Unlike standard epoxies, these variants are less prone to taking on a yellow tint over time, helping to preserve the intended look of your outdoor or indoor floor. However, while low-yellowing epoxy offers improved performance, no epoxy is entirely immune to UV effects; it’s a more robust solution for coloured aggregates, particularly in areas with regular sunlight.

Best Uses for Low-Yellowing Epoxy

This type of epoxy is ideal for resin-bound gravel or pebble flooring where decorative colours need to last. For example, low-yellowing epoxy is well-suited to driveways, footpaths, and patios using coloured stones. It is specifically recommended for use with coloured aggregates, as it helps maintain colour fidelity better than basic epoxies, yet is not suitable with pure white stones, where yellowing would be more noticeable. For white or very pale stones, a non-yellowing polyurethane binder is often preferable.

Products like the Flowstone Complete Permeable Floor Kit provide detailed resin selection advice to help you match the right binder to your chosen aggregate, ensuring a durable and attractive result.

When This Matters Most

• You are installing a decorative outdoor path or patio in a sunny area.
• Your project uses coloured pebbles and you want to avoid premature fading or discolouration.
• Maintaining a consistent colour over time is important for the overall look of your surface.
