Choosing Low-Yellowing Epoxy for Permeable Coloured Stone Floors

When installing a resin-bound floor using coloured decorative aggregates, the type of resin binder you choose can affect both the look and durability of your surface. Low-yellowing epoxy is a wise option for maintaining colour integrity outdoors.

Why Use Low-Yellowing Epoxy?

Standard epoxy resins can yellow over time, particularly when exposed to sunlight. This natural process may dull or alter the shade of coloured stones, leading to a faded or patchy appearance. Low-yellowing epoxy is formulated to reduce this colour change, keeping decorative surfaces looking brighter and more consistent for longer. This makes it ideal for use with darker or richly tinted aggregates in outdoor settings.

Selecting the Right Binder for Your Project

For white or especially light stones, a polyurethane binder is usually recommended, as it offers the best resistance to yellowing and a clear finish. For coloured aggregates, however, using a low-yellowing epoxy provides balance between durability and cost while still helping preserve the intended colour. Kits like the Flowstone permeable floor kit offer clear resin guidance to ensure you select the correct binder for your chosen aggregate colour.

When Low-Yellowing Matters Most

If your project features richly coloured or decorative stones exposed to direct sunlight, the benefit of a low-yellowing epoxy becomes more apparent. This choice is particularly important for patios, walkways, and driveways where aesthetics need to be maintained over time.
