Non-Yellowing Polyurethane for Outdoor Paving

Choosing a non-yellowing polyurethane binder is essential for outdoor resin paving projects, especially when clarity and lasting appearance matter most. Here’s what you need to know for making the right choice.

Why Non-Yellowing Polyurethane?

Outdoor resin surfaces are constantly exposed to sunlight and harsh weather. Traditional resins may develop a yellow tint over time, particularly noticeable with light or white aggregates. Non-yellowing polyurethane is specifically formulated to resist this discolouration, preserving the original look of your paving for longer. This makes it ideal for decorative areas or spaces where a pristine finish is needed.

How to Choose and Apply the Right Binder

When working with white or pale stones, a clear, UV-resistant polyurethane such as Polirock ensures the aggregate stays bright over time. To get the best result:

Mix the binder and stones thoroughly following the specified ratios (usually around 3% binder by weight of stones).
Apply on a dry, clean base to allow optimal bonding and drainage.
Work in suitable weather conditions, avoiding extremes of temperature or humidity, for proper curing.

When Non-Yellowing Polyurethane Matters

This type of binder is especially important for feature areas, driveways or paths where white or pale stones are used. In these settings, a non-yellowing formula prevents unsightly colour shifts that can affect the overall appearance.
