If you want your outdoor resin paving to retain its original look for years, using a non-yellowing polyurethane binder is key. This guide explains why this matters and how to choose the right product, especially for white or light stones.
Why Choose Non-Yellowing Polyurethane?
Outdoor resin pavements are constantly exposed to sunlight, which can cause many conventional binders to change colour over time. Polyurethane resins formulated to be non-yellowing offer superior resistance to UV rays, helping white and light-coloured stones remain bright and clear. This is especially important if you’re creating decorative, high-visibility surfaces such as patios, driveways, or pathways using pale aggregates.
How to Select the Right Binder for Your Project
When selecting a binder, consider both the shade of your aggregate and the exposure level of your surface. For white or very light stones, products like Polirock Polyurethane Binder are specifically designed to resist yellowing and keep stones clear, even under harsh sunlight. For other coloured stones, low-yellowing epoxies may suffice, but always check product suitability for your intended look. Always follow the manufacturer’s mixing and application instructions for best results and durability.
When Is Non-Yellowing Polyurethane Essential?
- Surfaces with white or light pebbles or gravel
- Areas in direct or prolonged sunlight
- Decorative, high-traffic outdoor settings where appearance matters
In these cases, investing in a non-yellowing product prevents unsightly discolouration and maintains the surface’s original style.
