Understanding Non-Yellowing Polyurethane for Outdoor Resin Floors

← Back to Which permeable flooring should I install in my garden?

Choosing the right binder is crucial when creating a durable garden floor with resin and stones. Non-yellowing polyurethane offers a clear, long-lasting finish, especially for bright, light-coloured aggregates such as white pebbles.

What Is Non-Yellowing Polyurethane?

Non-yellowing polyurethane is a specialist resin binder designed to resist discolouration from sunlight and weather exposure. Unlike standard resins, it helps maintain a clear, colour-true finish on outdoor surfaces. This is particularly important for resin-bound floors featuring white or light stones, where any yellowing would quickly become noticeable.

Application Tips and Advantages

Products like Polirock Polyurethane Binder are formulated for easy mixing with aggregates. Use approximately 3% binder by stone weight for best results. Always blend thoroughly and spread evenly to ensure a robust, permeable surface that stays bright season after season. This type of binder is also weather and UV resistant, supporting a safe, anti-slip, and visually appealing finish.

When Non-Yellowing Matters Most

• Ideal for white or pale coloured pebbles where yellowing would show quickly.
• Recommended in sunny, exposed garden spots.
• Helps keep pathways, patios, and decorative surfaces looking fresh and clean longer.
