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

← Back to How much does a driveable resin paving kit cost?

For outdoor resin-bound paving projects, the choice of binder can make a big difference in appearance and longevity. Low-yellowing epoxy is specially formulated to maintain colour vibrancy under sunlight, making it popular for coloured aggregate surfaces.

Understanding Low-Yellowing Epoxy

Low-yellowing epoxy refers to resin binders designed to resist yellowing and discolouration caused by exposure to UV rays. While all epoxies will change slightly over long periods, low-yellowing formulas help keep coloured stones and aggregates looking bright and true for much longer. This makes them particularly valued in applications where surface colour is a key feature, such as patterned driveways, decorative patios, or pathways using tinted gravels.

Choosing the Right Binder for Your Aggregate

When selecting a binder for a pebble or resin-bound surface, it’s important to match the resin type to the aggregates used. For white or very light stones, polyurethane binders are often preferred due to their exceptional non-yellowing qualities. For coloured aggregates, a high-quality low-yellowing epoxy provides a strong bond while supporting the integrity of the surface colour. Products like the Flowstone Complete Permeable Floor Kit offer easy guidance on which binder best suits your project.

When Low-Yellowing Epoxy Matters Most

• Driveways with decorative or coloured aggregates: Keeps your surface looking fresh and vibrant.
• Areas exposed to direct sunlight: Reduces the impact of UV-related fading.
• Projects where appearance is a priority: Ideal for patios, garden paths, and external spaces intended to retain a particular colour scheme.
