If you are installing resin-bound permeable paving, choosing the right resin is key to a durable, attractive finish. Low-yellowing epoxy resins offer a major advantage for outdoor projects, especially when used with coloured aggregates.
What Does ‘Low-Yellowing’ Mean?
Standard epoxies can develop noticeable discolouration when exposed to sunlight, often turning yellow over time. Low-yellowing epoxies are specifically formulated to better resist this effect, so your paving surface keeps its intended colour for longer. This is particularly important if you’re using coloured stones where colour integrity matters most.
When to Choose Low-Yellowing Epoxy
If you’re installing a permeable floor in areas with significant sunlight or wish to maintain brightly coloured finishes, low-yellowing epoxy is the ideal binder. It’s an excellent match for coloured aggregates in resin-bound kits like Flowstone. For light or white stones, consider dedicated non-yellowing polyurethane options instead, as even low-yellowing epoxies may still alter their appearance over time.
Application Tips
- Apply only to dry surfaces to avoid moisture issues during curing.
- Measure the recommended resin dosage carefully to ensure proper strength and finish quality.
- Avoid installing in high humidity, very low, or very high temperatures, as these conditions can impact curing and durability.
When Colour Retention Matters
Low-yellowing epoxy is especially relevant for driveways, garden paths, and patios where paving is visible and exposed to the elements. Choosing the right binder ensures your project looks good and lasts longer in UK conditions.
