Facebook← Back to Which product should I choose for professional permeable surfaces?
Professional permeable surfaces often require resins that not only bind aggregates securely but also maintain appearance over time. Low-yellowing epoxy offers a reliable solution for coloured stone installations exposed to sunlight, minimising discolouration.
What Is Low-Yellowing Epoxy and Why Use It?
Low-yellowing epoxy is formulated to resist the typical ambering that can occur with standard epoxy resins when exposed to UV light. While complete UV resistance is not characteristic of most epoxies, a low-yellowing variety reduces the rate and extent of discolouration, especially important with coloured aggregates. This ensures your paths or driveways remain visually appealing over time without rapid colour shift.
Choosing the Right Low-Yellowing Epoxy for Your Project
For professional permeable installations using coloured stones, opt for a resin system that specifies low-yellowing properties. The Flowstone Permeable Floor Kit provides clear guidance, recommending low-yellowing epoxy for coloured pebbles to help preserve the decorative finish outdoors.
- Check product suitability for your chosen stone colour.
- Always follow recommended ratios and instructions for best results.
- Apply only within the recommended temperature range (above 10°C).
When Is Low-Yellowing Epoxy Essential?
Low-yellowing epoxy matters most in exposed outdoor areas where the aesthetic integrity of coloured stones is crucial. If you‘re using white aggregates, however, a non-yellowing polyurethane binder may be preferred for greater clarity and UV stability. For all other shades, a conservatively formulated low-yellowing epoxy gives a practical balance of performance and cost.
