What Is Low-Yellowing Epoxy and Why Use It?

← Back to Is permeable pool paving worth it?

Low-yellowing epoxy is a type of resin binder designed to resist colour change over time when exposed to sunlight. This makes it particularly valuable for outdoor surfaces where maintaining appearance is important.

Why Choose Low-Yellowing Epoxy?

Many traditional epoxy resins can discolour—turning yellow or dull—especially when exposed to UV rays. Low-yellowing formulas are specifically engineered to minimise this effect, helping coloured or decorative aggregates keep their intended look for longer. This matters most when preserving aesthetic value in features like paths, patios or permeable pool surrounds.

It’s worth noting that for the brightest white stones, such as Carrara marble, a non-yellowing polyurethane binder is recommended. However, for most coloured gravels and stones, a quality low-yellowing epoxy provides strong adhesion and lasting colour clarity.

Using Low-Yellowing Epoxy in Permeable Resin-Bound Surfaces

When installing permeable paving—such as in the Flowstone Complete Kit—choosing the right binder is integral. A low-yellowing epoxy pairs well with coloured pebbles, helping the surface remain visually appealing while enabling effective drainage. The binder securely holds aggregates in place, creating a stable, slip-resistant finish that manages water runoff without sacrificing looks.

When This Matters Most

Selecting a low-yellowing epoxy is particularly important for surfaces exposed to strong sunlight or for paving using decorative stones where colour retention is key. If you’re investing in features that merge function with style—such as a colourful poolside area or statement garden path—opting for the right binder ensures your design stands the test of time.
