Which Aggregates to Use for Resin-Bound Flooring?

Q: Recommended Types and Combinations

The most reliable option is a washed aggregate , supplied specifically for resin applications. These products typically include rounded or angular stones between 4–8 mm, available in a range of colours. You can blend these pebbles with other compatible granules like marble, granite, or porphyry to achieve different visual effects or to match your landscape aesthetics. Always ensure each type is clean, dry, and designed for outdoor permeable floor use.

What Aggregates are Suitable for Resin Surfaces?

Choosing the right aggregates is crucial for achieving a durable, attractive, and permeable resin-bound surface. Not all pebbles are equally suitable—here’s how to ensure the best result.

Why Aggregate Selection Matters

For resin-bound flooring, always use pre-washed and fully dried pebbles or stones specifically intended for use with resin. These decorative aggregates offer consistent shape, size, and moisture content, which helps the resin adhere thoroughly and form a strong, stable surface. Using stones that haven’t been properly cleaned or dried can result in poor bonding, uneven curing, or even surface failure over time.

Practical Application Tips

Check that your chosen aggregates are labelled as suitable for resin-bound or permeable surfaces.
Avoid landscaping pebbles from garden centres unless stated for resin use—they may retain dust or moisture.
Use approximately 1 x 25 kg bag of aggregate per square metre when laying a standard surface.
Mix aggregates thoroughly with the correct resin binder to ensure each stone is coated and locked in place.

When Aggregate Choice Matters Most

Selecting the appropriate aggregate is especially important for driveways, paths, and terraces where water permeability and longevity are priorities. Pre-washed, resin-ready stones help prevent puddling and improve surface resilience in the UK climate.
