Comparing Aggregates and Binders for Resin Bound Surfaces

When selecting aggregates for resin bound paving, it’s important to consider three core factors: permeability, aesthetics, and long-term durability. Our specialist product range addresses each need—take a closer look below to see which system fits your requirements:

• “Flowstone” – Complete Permeable Floor Kit with Pebbles and Resin pairs high-quality natural pebbles with a choice of non-yellowing polyurethane or low-yellowing epoxy binder. It’s ideal for those seeking a permeable solution for outdoor areas prone to water pooling, offering simple application and full kit convenience.
• “Polirock” – Polyurethane Binder for White Stones, 2kg Two-Component Kit is designed specifically for white or natural stone aggregates. This weather-resistant binder ensures a no yellowing clear finish, maintaining brightness even under UV exposure.
• “Trasparente” – Epoxy Binder for Coloured Pebbles and Grits delivers a crystal-clear epoxy resin finish that’s especially UV-resistant and non-yellowing—perfect for bold, coloured aggregates on decorative patios or driveways.

All these solutions are part of our Pebble Floors and pebble floors category ranges, ensuring a wide choice of aggregate colours and granule sizes for optimal personalisation.

Why Aggregate Choice Matters for Resin Bound Paving

The performance and appearance of a resin bound surface relies on using high-quality, compatible aggregates. Washed, dust-free stones in various grades ensure strong bonding with the selected resin, minimise voids, and maximise permeability.

The resin binder you select should match your chosen aggregate. For example, white Carrara pebbles require non-yellowing polyurethane such as Polirock, while coloured or warm-tone grits are best paired with clear epoxy binders like Trasparente. Our Flowstone kit provides full guidance, helping users achieve lasting results with the right material combination for any outdoor application.

Key benefits of choosing the right aggregate and resin system:

• Permeable solution: Allows water drainage, prevents puddles and helps manage rainfall
• Cost-effective renewal: Easily restore driveways and paths with durable materials
• Customisable finish: Select from a wide range of colours and granule sizes
• Simple application: Kits and binders suited to all skill levels

Installation Tips for Resin Bound Aggregates

To achieve the best outcome, always follow manufacturer-recommended guidelines for mixing, surface preparation, and resin-to-aggregate ratios. For larger areas, a cement mixer can ease preparation, while compacted and clean substrates ensure optimal bonding. Keep in mind:

• Polyurethane resin systems such as Polirock should only be used with white/natural stones—avoid epoxy on white Carrara gravel.
• Coloured and dark aggregates benefit from clear epoxy binders like Trasparente for both performance and aesthetics.
• Always install in suitable weather, steering clear of high humidity, and extreme temperatures to ensure thorough resin curing.
• Consult the step-by-step application instructions included in each Flowstone kit for maximum ease and reliability.

Proper surface prep, careful aggregate selection, and choice of binder combine to deliver a resin bound system that is both resilient and visually striking.
