How to Choose the Right Binder for Your Aggregate Colour

Which Binder Should I Use for Different Aggregate Colours?

Selecting the right binder for your chosen aggregate colour is essential to achieve a durable, visually appealing resin paving surface that won’t lose its vibrancy over time. Here’s how to make the ideal choice based on your aggregate finish.

Best Binders for White and Light Aggregates

White and light-coloured stones require special care to prevent yellowing and preserve their clarity. Polyurethane binders, such as the Polirock Polyurethane Binder, are formulated to stay clear, even under exposure to UV rays and outdoor elements. This ensures white stones retain their pure finish and stand the test of time in UK weather conditions.

Choosing a Binder for Coloured or Dark Aggregates

Dark or coloured pebbles benefit from a transparent, low-yellowing epoxy binder. For these applications, a product like the Trasparente Epoxy Binder offers UV stability and a clear finish that accentuates the aggregate’s natural hues. This makes it an excellent choice for creating striking and lasting decorative surfaces.

Practical Advice for Your Installation

Always check binder specifications: ensure you select a non-yellowing polyurethane for light stones and a UV-stable epoxy for vibrant or dark aggregates.
Mix thoroughly: combine binder and stones completely before laying for a consistent, bonded finish throughout your surface.
Follow included guidance: kits like the Flowstone Permeable Floor Kit include detailed, step-by-step instructions to help ensure the right resin choice for your aggregate.

When This Matters

Selecting the correct binder is particularly important for external spaces exposed to sunlight and weather. The wrong choice could lead to a dull or yellowed finish over time, affecting both appearance and performance.
