When creating vibrant, long-lasting resin-bound stone surfaces outdoors, choosing the right binder is key. Low-yellowing epoxy is specifically recommended for coloured stones to preserve their true hues in sunlit environments.
Why Use Low-Yellowing Epoxy with Coloured Stones?
Standard epoxy resins can yellow over time, especially with exposure to sunlight, which may dull or distort the original tones of coloured stone aggregates. Low-yellowing epoxy is specially engineered to minimise this effect, helping maintain the clarity and brightness of stones such as red, green, or brown granules used in permeable paths, patios, or plaza surfaces.
Choosing and Applying Epoxy for Outdoor Surfaces
When selecting a binder, check that it is explicitly labelled as “low-yellowing” and designed for outdoor use. For projects using lighter or white stone, a non-yellowing polyurethane is best, but for most coloured aggregates, low-yellowing epoxy ensures colour stability without compromising durability or drainage. For a seamless installation, consider a complete system like the Flowstone permeable floor kit, which includes guidance specific to aggregate and binder pairing. Mix according to instructions and apply on a suitable substrate to create a resilient, vibrant finish.
When This Matters
Opting for low-yellowing epoxy is essential when visual appeal and colour retention are priorities. Ideal for public squares, decorative paths, and any environment where stone colour is part of the design statement and prolonged UV exposure is expected.
