Low-Yellowing Epoxy: What You Need to Know

Low-yellowing epoxy is a specialised resin formulation designed to minimise colour change over time, making it a smart choice for outdoor permeable flooring where appearance matters. If you are planning a permeable driveway or patio, understanding when to use low-yellowing epoxy will help your surface retain its fresh, vibrant look longer.

What Is Low-Yellowing Epoxy?

Standard epoxy resins can discolour or yellow after exposure to sunlight and the elements, especially when used outdoors. Low-yellowing epoxy uses advanced chemistry to slow this process, helping protect the original colour of your chosen aggregates, especially coloured stones. This is particularly beneficial for driveways, patios, and paths that need to remain attractive and welcoming.

Choosing the Right Binder for Your Project

For permeable pebble or resin-bound surfaces, the binder plays a key role in both durability and appearance. If your design features white stones, a non-yellowing polyurethane resin is recommended. For surfaces using coloured stones or blends, low-yellowing epoxy strikes a balance between colour protection and practical performance. Flowstone Complete Permeable Floor Kit provides guidance on selecting suitable resins based on your chosen aggregate colours.

When Low-Yellowing Epoxy Matters Most

Driveways or paths in full sun where UV exposure is highest
High-traffic entrances that should stay visually appealing
Projects using coloured or decorative stones needing lasting vibrancy
