How to Thoroughly Mix Aggregate and Resin Binder for Paving

Q: Step-By-Step Mixing Guide

Measure accurately: Check the required aggregate-to-binder ratio. For example, using Polirock polyurethane binder , you would typically use 6–8 kg aggregate for each 1 kg binder (check specific product instructions). Use a forced action mixer: Place the washed, dried aggregate in first, then add the freshly mixed resin binder. Mix for 3–5 minutes: The goal is even, complete coating without leaving dry patches or clumps, but avoid over-mixing which may cause bubbles. Prompt laying: Once mixed, immediately spread the batch before the resin begins to cure.

Q: Tips for a Perfect Mix and Practical Application

Clean tools: Always use clean, dried tools and equipment to prevent contamination. Batch size: Only mix what you can lay in one go to avoid curing in the mixer. Surface readiness: Ensure the substrate is clean, dry, and prepared before you begin mixing.

How to Properly Mix Aggregate and Resin Binder Before Laying

Getting the mix right is essential when creating resin bound paving. Properly blending aggregate with binder ensures a smooth, cohesive, and long-lasting surface with the drainage and aesthetic you want.

Why Thorough Mixing Matters

When the aggregate (stones or grits) and resin binder are evenly combined, each stone is fully coated, leading to a more stable surface and consistent appearance. Inadequate mixing can leave dry patches, weaker bonding, or uneven colour, so take care from the start to achieve the best results.

When This Really Matters

Paying close attention to mixing technique is crucial for driveways, paths, and patios exposed to traffic and weather, where durability and finish are key. Poorly mixed batches are more likely to degrade over time or lead to patchy areas.
