← Back to Which product should I choose for professional permeable surfaces?

When installing professional permeable surfaces, particularly with white stones or light-coloured aggregates, selecting the right resin is vital for both aesthetics and longevity. Non-yellowing polyurethane offers a clear, lasting finish that resists discolouration outdoors.
Why Choose Non-Yellowing Polyurethane?
Standard resins can turn yellow or cloudy in sunlight, especially on pale stones. Non-yellowing polyurethane is specifically formulated to resist UV exposure, keeping white and light stones bright and attractive over time. This makes it an ideal choice for outdoor installations where appearance matters, such as pathways, patios and feature driveways.
Application Tips for the Best Finish
Before mixing, ensure your stones—like pre-washed white pebbles—are clean and dry. Use the recommended resin-to-aggregate ratio (typically about 3% by weight, such as with the Polirock Polyurethane Binder) for optimal performance. Work in suitable weather, ideally above 10°C, to ensure a consistent set. Always follow product guidance for surface preparation and curing time for durable, professional results.
When Non-Yellowing Polyurethane Matters Most
- White or very light aggregates: Maintains their natural colour and prevents unsightly yellowing.
- High-visibility areas: Ensures a crisp, clean finish for residential driveways or public walkways.
- Outdoor installations: Withstands variable UK weather and prolonged sunlight exposure.
