Low-yellowing epoxy is a popular binder for creating resin-bound permeable terraces, paths, and driveways. It helps surfaces maintain their vibrant appearance while providing essential durability outdoors in the UK climate.
What Is Low-Yellowing Epoxy?
Low-yellowing epoxy is a type of resin formulated to resist yellowing from UV exposure better than standard epoxy options. When used as a binder with natural or coloured pebbles, it helps to preserve the intended colour and presentation of permeable paving—especially where darker or brightly coloured aggregates are installed.
Choosing and Using the Right Resin Binder
For most outdoor resin-bound surfaces using coloured stones, a low-yellowing epoxy binder is recommended as it balances strength, adhesion, and long-term colour protection. However, for very light or white aggregates, such as white Carrara gravel, specialist polyurethane binders are preferable to prevent any discolouration over time. Always follow the supplier’s guide on mixing ratios and site preparation for optimal results. For a ready-to-use solution, the Flowstone Complete Permeable Floor Kit provides materials and step-by-step instructions designed around these best practices.
When This Matters Most
Using low-yellowing epoxy is particularly important for outdoor areas exposed to sunlight where colour longevity matters. It ensures paved surfaces such as driveways, footpaths, and patios retain their attractive finish for longer, reducing the need for early renovations.
