How to Choose Aggregates & Resin for Multi-Purpose Courts

Carefully Select Your Aggregate and Resin System

Selecting the right aggregate and resin combination is the foundation for building a reliable, long-lasting multi-purpose resin court. Your choices will define how the surface performs under foot and in changing weather.

Understanding Your Aggregate Choices

The aggregate provides both structure and appearance to the court surface. Natural pebbles, coloured grits, and specialist gravels can be chosen for aesthetics and slip resistance. White stones create a clean look but require specific binders to maintain clarity, while coloured and dark aggregates allow for creative, vibrant finishes.

Choose angular or graded stones for better bonding and surface stability.
Consider size and texture for desired grip and drainage.
Match aggregate colour to a suitable resin to avoid yellowing or fading.

Selecting the Right Resin Binder

The resin binder secures aggregate in place, affecting both durability and appearance. For white stones, opt for a non-yellowing polyurethane binder such as Polirock to maintain brightness. For coloured or darker stones, a low-yellowing epoxy binder offers lasting clarity and UV stability, such as “Trasparente.” Ensure your resin system is suitable for outdoor use and permeable flooring to maximise longevity and drainage.

Practical Tips for Buying and Application

When sourcing materials, choose complete systems designed for outdoor courts, like the Flowstone kit, to ensure all components are compatible. Check that the product includes formulation advice for aggregates and surface size. During application, mix the aggregate thoroughly with the resin for even encapsulation, and always follow manufacturer instructions regarding sub-base requirements and mixing equipment.

When Careful Selection Matters

Taking the time to match your aggregate and resin ensures the court’s surface is not just attractive but also fit for the intended level of footfall, weather exposure, and drainage needs. This attention to detail is crucial for surfaces that will see frequent multi-purpose use.
