Understanding Low-Yellowing Epoxy in Permeable Paving

Low-yellowing epoxy is a type of resin binder specifically formulated to maintain its clarity and colour integrity when exposed to UV and general outdoor conditions, making it a good choice for colourful resin-bound surfaces.

This special epoxy is engineered to resist the natural yellowing process that can occur over time, particularly from exposure to sunlight. While all epoxies will eventually show some change, low-yellowing versions help preserve the vibrancy of coloured stones for longer, especially on driveways, patios and decorative outdoor walkways.

When and Why Should You Use It?

Low-yellowing epoxy is recommended when installing permeable flooring with coloured aggregates, such as natural or decorative pebbles. Using the right binder ensures the colours stay more stable and attractive over time, rather than quickly fading or yellowing. For white stones, a non-yellowing polyurethane is typically preferable. When working with coloured stones, like those in the Flowstone Complete Permeable Floor Kit, opt for low-yellowing epoxy to showcase the natural shades at their best.

Basic Guidance for Application

Check manufacturer recommendations for the correct binder for your chosen stone colour.
Mix well to ensure even resin distribution and a uniform finish.
Apply at temperatures above 10°C for the best results and durability.
Follow step-by-step instructions for optimal mixing and installation.

When This Matters Most

Using low-yellowing epoxy is vital for areas where appearance is especially important or where surfaces will be in direct sunlight—such as driveways and garden paths. If you want your paving to stay colourful and free from obvious yellowing, the right choice of binder makes a noticeable difference over time.
