Facebook← Back to Permeable Flooring vs Concrete – Which is Best for Your Project?
When installing or restoring resin-bound flooring, choosing the right binder is crucial for long-lasting looks. Non-yellowing polyurethane is a top choice to maintain colour stability for outdoor surfaces exposed to the elements.
Why Choose Non-Yellowing Polyurethane?
Outdoor resin floors are constantly exposed to sunlight and weather. Some resins, especially standard epoxies, are prone to yellowing, which affects lighter and white aggregates noticeably. Non-yellowing polyurethane is specifically engineered to minimise this discolouration, keeping your surface attractive for longer.
It’s especially recommended when using white or light-coloured stones, such as Carrara marble, where yellowing can be most visible.
Tips for Application and Product Selection
Before starting your project, verify that the binder is suitable for outdoor use and offers UV resistance. While polyurethanes generally deliver superior anti-yellowing performance over standard epoxies, always follow the manufacturer’s guidance for best results.
- For white or very light aggregates, always opt for non-yellowing polyurethane.
- If you’re using coloured aggregates, a low-yellowing epoxy may suffice, but polyurethane still offers extra protection.
- The Flowstone Complete Permeable Floor Kit provides clear guidance: non-yellowing polyurethane for white stones, low-yellowing epoxy for coloured or dark stones.
When This Matters Most
Choosing a non-yellowing binder is vital if your surface will be in direct sunlight or made with bright, light-coloured stones. In shaded or mixed-toned areas, yellowing may be less obvious, but using polyurethane still delivers added peace of mind and durability in the long run.
