Low-Yellowing Epoxy for Permeable Paving

Choosing the right binder is essential for the beauty and longevity of resin-bound, permeable paving. A low-yellowing epoxy helps maintain the vibrance of stone blends in outdoor floors, especially where colour preservation matters most.

What Makes an Epoxy ‘Low-Yellowing’?

All conventional epoxies will naturally yellow over time when exposed to sunlight, but modern low-yellowing variants are engineered to slow this process. This makes them a preferred choice for outdoor surfaces featuring coloured stones or darker aggregates where colour shift would be more noticeable. For white stones, such as Carrara, a completely non-yellowing binder like specialised polyurethane is advised as even subtle yellowing can impact appearance.

When and How to Use Low-Yellowing Epoxy

Low-yellowing epoxy is particularly useful for driveways, patios, and garden paths utilising coloured gravels. After preparing your substrate and ensuring all stones are clean and dry, simply combine your aggregate with the specified quantity of low-yellowing epoxy, then spread and level it. For a convenient approach, consider a comprehensive kit such as the Flowstone Complete Permeable Floor Kit, which includes precise resin guidance tailored to the type of aggregate you choose.

When This Matters Most

If you’ll be installing a decorative resin-bound surface exposed to sunlight—such as outdoor walkways or terraces—opting for low-yellowing epoxy will keep colours distinct for longer, making ongoing maintenance easier and your new paving more attractive.
