Non-Yellowing Polyurethane for Permeable Paving

Non-yellowing polyurethane is an essential binder for achieving durable, clear finishes in permeable paving installations—especially where bright or white aggregates are used. Its clarity and resistance to discolouration make it a top choice for projects where appearance matters.

Why Choose Non-Yellowing Polyurethane?

Standard resins can develop a yellow tint over time, particularly under UV exposure. Non-yellowing polyurethane addresses this by staying clearer for longer, helping to preserve the true colour of white or light-coloured stones in outdoor surfaces. This clarity is valued in decorative projects and locations where long-lasting visual appeal is needed—such as driveways, patios, and landscaped paths.

How to Use Non-Yellowing Polyurethane

To make the most of non-yellowing polyurethane, select a dedicated binder designed for natural or white aggregates, such as the Polirock Two-Component Polyurethane Binder. For best results:

Mix the binder thoroughly with washed, dry stone aggregates, following the recommended resin-to-stone ratio (typically around 3% resin by weight for 4–8 mm aggregate).
Ensure the working area is clean and level before applying your mix.
Observe curing guidelines, working in moderate temperatures and avoiding high humidity for optimum performance.

When Non-Yellowing Formulation Matters

Non-yellowing polyurethane is especially relevant when using white stones, marble chips, or other light-tone aggregates. If long-term clarity and retention of natural colour are priorities, a UV-resistant binder is critical. For darker or coloured aggregates, a standard low-yellowing resin may be suitable, but always check product advice based on your project’s colour scheme.
