Understanding Low-yellowing Epoxy for Outdoor Surfaces

Choosing the right resin for outdoor paving is crucial to ensure your terrace stays attractive over time. Low-yellowing epoxy is often recommended for coloured stone surfaces, providing a more durable and colour-stable finish that resists discolouration from sunlight and weather.

What is Low-yellowing Epoxy?

Low-yellowing epoxy is a type of resin binder designed to minimise the colour change that typically occurs when epoxy is exposed to UV light. Standard epoxies can darken or yellow when used outdoors, especially with lighter or brightly coloured aggregates, affecting the visual appeal of your terrace. Low-yellowing formulations are engineered to stay clearer for longer, which is particularly valuable for maintaining the original colour of non-white stones in your paving design.

Where and How to Use Low-yellowing Epoxy

Low-yellowing epoxy is the preferred choice for resin-bound pebble systems where coloured stones are used, as it helps protect the look of your flooring. It’s suitable for pedestrian and light-vehicle surfaces, such as patios and garden paths. For optimal longevity and appearance, follow the manufacturer’s guidance on mixing and application. The Flowstone Complete Permeable Floor Kit comes with clear recommendations for selecting the right resin for your aggregate, making it easier to achieve a professional result.

When This Matters Most

Using a low-yellowing epoxy is especially important for outdoor terrace projects where coloured granules are chosen. If your design relies on maintaining a specific stone tone or pattern, or if your floors receive significant sunlight, investing in a high-quality, low-yellowing binder is key to ensuring lasting curb appeal.
