Facebook← Back to Permeable Flooring vs Concrete: Which Is Right for You?
Selecting the right resin binder is essential for both the appearance and durability of resin-bound stone floors. Specific combinations protect colour and ensure your surface stays looking its best.
Why Resin Choice Depends on Stone Type
White or light-coloured stones, such as Carrara marble, are prone to yellowing if not paired with an appropriate resin. To maintain their crisp appearance, a non-yellowing polyurethane binder is preferred. For most coloured pebbles commonly used outdoors, a low-yellowing epoxy is typically suitable and provides long-lasting, stable results.
How to Match Resin and Aggregate
Always consult product-specific instructions to ensure compatibility between your aggregate and binder. For example, the Flowstone kit provides clear resin recommendations: non-yellowing polyurethane for whites and low-yellowing epoxy for coloured stones. Following this advice preserves surface finish by preventing premature discolouration and helping your floor wear evenly.
When Getting This Right Matters
- If your aggregate is white or very pale, even modest sunlight can cause noticeable yellowing unless a suitable binder is used.
- For decorative or high-traffic areas, matching the correct resin ensures not just stable colour, but reliable strength.
