What is Non-Yellowing Polyurethane & Why Does It Matter?

← Back to How much does a driveable resin bound gravel kit cost?

Non-yellowing polyurethane is a specialised binder used in resin bound surfaces, especially where a clear, lasting finish is essential. It is designed to resist discolouration from sunlight, making it a smart choice for outdoor applications needing a pristine appearance over time.

Why Choose Non-Yellowing Polyurethane?

Standard resins and binders can develop a yellow tint after prolonged exposure to UV light, which can spoil the look of light coloured or white stone surfaces. Non-yellowing polyurethane addresses this by providing a durable, clear binding layer that maintains the natural colour of your aggregates. This is particularly important if you want your driveway, path, or patio to retain its original brightness and clarity for years without routine patching or resurfacing.

How to Use Non-Yellowing Polyurethane

Installing a resin bound system with a non-yellowing polyurethane binder is straightforward. Simply mix the polyurethane resin with your chosen aggregate, then apply and level as per kit instructions. For white and light-toned stones, use a binder like Polirock to prevent yellowing and achieve a striking, professional finish. Always measure your surface carefully and mix the correct quantities for optimal strength and drainage.

When Is Non-Yellowing Polyurethane Essential?

• White or Light-Coloured Aggregates: To prevent yellowing and preserve brightness.
• Highly Visible Areas: Such as front driveways and entrances where long-lasting aesthetics matter.
• Outdoor Surfaces Exposed to Sunlight: Where UV resistance is needed to maintain surface appearance.
