Facebook← Back to What is the best permeable paving for outdoor renovations?
If you’re looking to renovate outdoor spaces with permeable paving, understanding the choice of resin is essential. Low-yellowing epoxy is a key option for coloured stone finishes, as it helps preserve the appearance and function of your surface over time.
What Is Low-Yellowing Epoxy and Why Is It Useful?
Low-yellowing epoxy is a specially formulated resin designed to minimise discolouration when exposed to sunlight and outdoor conditions. This makes it particularly suitable for resin-bound systems that use coloured aggregates. By selecting an epoxy with low-yellowing properties, you can enhance the lifespan and appearance of your paving without the finish turning noticeably yellow or dull—common concerns in outdoor applications.
How to Choose and Use Low-Yellowing Epoxy
For permeable outdoor surfaces using coloured pebbles or stones, low-yellowing epoxy is often the recommended binder. It ensures your chosen colour palette stays true over time, especially if the area receives ample sunlight. However, for white or very pale stones, it’s usually better to opt for a non-yellowing polyurethane resin for the clearest finish. Kits like the Flowstone system offer clear guidance on resin selection according to aggregate colour, simplifying this aspect for both DIYers and professionals.
When Low-Yellowing Epoxy Matters Most
- High-visibility areas: Entrances, patios, or paths where aesthetics are key.
- Coloured aggregate installations: Preserves intended shades longer, enhancing kerb appeal.
- Sunny exposure: Helps reduce the risk of colour change in areas exposed to UV rays.
