If you want a resin patio that keeps its colour and looks fresh for years, choosing the right epoxy binder is key. Low-yellowing epoxy is designed to help your outdoor surfaces stay vibrant even with regular sun exposure.
What Is Low-Yellowing Epoxy?
Low-yellowing epoxy is a type of resin formulated to better resist the gradual yellowing caused by sunlight and weather. While all epoxies may yellow over time, low-yellowing varieties are specifically designed to slow this process, making them suitable for coloured stone or pebble patios where maintaining a rich finish matters.
When to Use Low-Yellowing Epoxy Outdoors
If you’re installing a resin-bound patio with coloured stones, low-yellowing epoxy helps preserve the tone and appearance under UV and the unpredictable UK climate. However, for white or very light pebbles, it’s generally better to use a non-yellowing polyurethane binder, as it offers superior colour stability for those tones. Kits like the Flowstone Complete Permeable Floor Kit include guidance to help you match the right resin to your aggregate colour.
Tips for Successful Application
- Check weather: Aim for dry, moderate conditions to avoid affecting the epoxy’s cure and finish.
- Select the right mix: Use low-yellowing epoxy with coloured stones, and always follow the suggested proportions.
- Prepare the surface: Clean and dry aggregates yield the best bond and visual result.
When Low-Yellowing Epoxy Matters Most
Low-yellowing epoxy is particularly useful for patios in exposed areas or where rich, deep aggregate colours are part of the design. This choice keeps surfaces looking newer for longer and supports the value of your DIY effort.
