If you want your resin-bound outdoor flooring to keep its original colour and finish for longer, choosing a low-yellowing epoxy binder is a smart move. This guide explains where and why low-yellowing epoxy is used, helping you select the best product for your outdoor surfaces.
What Is Low-Yellowing Epoxy?
Low-yellowing epoxy is a resin that minimises the yellowing or discolouration caused by exposure to sunlight and outdoor conditions. While all epoxies are subject to some change over time, low-yellowing formulas are specially developed to better preserve colours—especially important for decorative stones.
Why Use Low-Yellowing Epoxy with Pebble Floors?
When installing resin-bound aggregate surfaces such as patios, footpaths, or driveways, the resin binder plays a vital role in maintaining the appearance. For coloured pebbles or stones, using a low-yellowing epoxy helps prevent around-the-edges yellowing that can develop with standard resins. This keeps the surface looking fresh, particularly in areas exposed to sunlight.
The Flowstone Complete Permeable Floor Kit is a great example—it recommends low-yellowing epoxy for coloured stones to help retain the vibrancy of your chosen finish.
Practical Tips for Choosing the Right Epoxy
- Colour matters: Use a low-yellowing epoxy for coloured stone surfaces. For white aggregates, consider a non-yellowing polyurethane for best results.
- Project type: If you’re working on a decorative outdoor floor like a garden path or terrace, selecting the right binder ensures your hard work stays attractive longer.
- Easy installation: Many kits, such as the Flowstone system, offer clear instructions for mixing the resin and stones—even suitable for DIY use.
When This Matters
Low-yellowing epoxy is most important for surfaces where colour and appearance are a priority, such as decorative patios or pathways in sunny spots. If you want to avoid having your coloured stones become dull or yellowed with time, investing in the right epoxy binder is key.
