When installing a resin-bound outdoor floor, choosing the right binder plays a big role in both appearance and durability. Low-yellowing epoxy is a smart choice for keeping coloured pebbles vibrant over time.
What Does Low-Yellowing Epoxy Mean?
Epoxy resins naturally react to sunlight and weather exposure, which can lead to yellowing—especially in traditional blends. ‘Low-yellowing’ epoxies are specially formulated to significantly reduce this colour shift, making them ideal when working with coloured stones or aggregates in outdoor surfaces. While not completely immune to the effects of UV, these binders help preserve the original look of decorative floors for longer compared to standard epoxy.
Choosing the Right Epoxy for Your Project
If you’re aiming for a surface with deep or bold colours, low-yellowing epoxy will help maintain the vibrancy and prevent early fading. For white or very light aggregates, it’s often better to use a dedicated non-yellowing polyurethane binder to avoid discolouration.
When selecting a floor kit such as the Flowstone permeable flooring kit, you’ll find guidance on which binder to choose according to your chosen aggregate colour—ensuring the most attractive, lasting finish.
When Colour Stability Matters Most
- Decorative patios or driveways in full sun
- Surfaces using coloured, grey, red, or natural stone pebbles
- Public or commercial spaces where appearance is important over time
In these situations, using a low-yellowing formula can make a noticeable difference in long-term satisfaction with your flooring.
