Non-Yellowing Polyurethane for Paving: What to Know

If you’re paving with white stones outdoors, choosing a non-yellowing polyurethane binder ensures your flooring retains its brightness and clarity over time. Non-yellowing polyurethane is especially valued for resisting the discolouration that often troubles standard resins exposed to sun and weather.

Why Use Non-Yellowing Polyurethane?

Unlike traditional resins, polyurethane formulas designed not to yellow stay clear and colourfast even under prolonged UV exposure. This is especially important when working with pale or white stones, as yellowing is most noticeable with light aggregates. Opting for a non-yellowing binder protects your installation’s clean, bright appearance for years.
