Limitations with White Gravel in Flowstone Kits

← Back to How does permeable paving work?

Using white Carrara gravel for permeable outdoor flooring delivers a crisp look, but it does come with specific requirements if you are working with the Flowstone kit. Here’s what to consider to preserve the clean, bright finish of white stones.

Why Binder Choice Matters for White Gravel

White Carrara and similar light stones are especially prone to yellowing when exposed to UV light—this is often made worse if epoxy-based resins are used. To keep the stones’ natural brilliance, it’s important to select a binder that remains clear over time.

Epoxy resins can develop a yellow tint, which is very noticeable on white pebbles.
Polyurethane binders are recommended for white aggregates as they provide better resistance against discolouration outdoors.

Practical Steps for White Stone Installations

When choosing materials for your project, opt for a dedicated polyurethane binder, such as Polirock. This will help maintain the fresh appearance of the stones and ensure your permeable floor offers long-lasting performance.

Check that the binder is labelled as non-yellowing and intended for use with white or light stones.
Use pre-washed, dried pebbles to ensure even binding and prevent staining.

When This Matters Most

Binder selection is especially crucial for decorative areas such as patios, driveways, and shared courtyards where a consistent, bright appearance is important. Investing in the right products will help avoid disappointment later as the surface weathers.
