How do I choose the right pebbles or aggregates?

Key factors when choosing pebbles or aggregates

Start by opting for washed and fully dried aggregates. Washing ensures the surface is clean and dust-free, which is vital for strong adhesion with the resin. The aggregates should match your desired look—for example, white stones create a crisp effect, while coloured or natural tones offer warmth and variety. Consider the following:

• Size: Smaller pebbles often provide a smoother finish, while larger grains can enhance drainage and visual texture.
• Colour: Select hues that suit your project and note that lighter colours may need specific resins to avoid yellowing over time.
• Shape and blend: Well-rounded, consistent granules distribute evenly, and you can mix types (e.g., marble or granite with pebbles) for a bespoke finish.

Ensuring permeability and practicality

One of the primary advantages of resin-bound floors is water permeability. Using purpose-designed washed pebbles helps water drain through efficiently, reducing puddles and runoff. Make sure to select aggregates specifically meant for permeable surfaces if your project calls for outdoor or garden installations.

Before installation, check that all aggregates are dry—moisture can interfere with the resin bond and finish. For high-traffic areas, stable, robust stones are preferred to maintain durability over time.

Practical tips for buying and installation

When purchasing aggregates, calculate the amount based on your surface area and desired depth. Kits like the Flowstone Complete Permeable Floor Kit provide helpful guidance, offering both pebbles and suitable resin binders. Always follow the provided instructions for mixing and applying to achieve a long-lasting result. If you’re combining different aggregates, test blend a small section first to see the effect.
