When installing or upgrading a driveable permeable floor, choosing the right resin binder is key to long-lasting performance and appearance. Low-yellowing epoxy is commonly recommended for coloured stone installations to help maintain visual appeal over time.
What Does Low-Yellowing Epoxy Mean?
A low-yellowing epoxy is formulated to resist discolouration caused by sunlight exposure—known as yellowing—better than standard epoxies. While all epoxies may eventually change slightly in colour when exposed to UV light, low-yellowing versions are designed to slow this process significantly, especially for outdoor use.
Choosing Resin for Coloured Stones
If you’re using coloured aggregates, such as decorative pebbles or gravel, a low-yellowing epoxy binder helps keep the original tones vibrant for longer. This is particularly important for driveways and paths that are regularly exposed to the elements. For installations with white or very light-coloured stones, a non-yellowing polyurethane binder is typically preferable, while low-yellowing epoxy binds work well with most other colour mixes.
See the Flowstone Complete Permeable Floor Kit for bundled options and specific resin recommendations tailored to your chosen aggregate.
When Does Low-Yellowing Epoxy Matter?
- If your permeable drive, path, or patio uses coloured gravel or pebbles
- Where the surface is exposed to direct sunlight and weather
- When maintaining a uniform or decorative finish over time is important
