How Should Epoxy Binder Be Used with Coloured Stones or Gravel?

Mixing Epoxy Binder with Coloured Stones

For the strongest and most visually appealing result, the epoxy binder should be thoroughly blended with the coloured stones or gravel before installation. This process coats every particle, encouraging proper encapsulation and strong bonding within the finished layer. Mixing can be done in a clean tub or, for larger batches, in a cement mixer—helping ensure all aggregates receive an even coating of resin for reliable stability and a uniform appearance.

• Measure: Accurately weigh both resin and stones as per the product guidance.
• Mix: Gradually add the resin to the stones, stirring continuously, until all surfaces are glossy and no dry areas remain.
• Work Time: Use the mixture promptly, as epoxy resins will begin to set after a certain period (refer to product data for specifics).

Laying and Finishing the Surface

After mixing, promptly spread the epoxy-stone mixture onto the prepared area. Even distribution and gentle tamping are important to remove air pockets and encourage adhesion with the sub-base. A trowel can help you level the surface and press the mix firmly. Ensure any base is clean, stable, and—ideally—primed with a suitable product such as Epoxyprimer for optimal adhesion on substrates like concrete or screed.

Once the material is laid, protect the area from weather and traffic until fully cured, typically within 24 hours. Avoid washing or heavy loads until the binder has hardened throughout.

When This Matters

Thorough mixing of epoxy binder with coloured stones is vital for projects where durability, weather resistance, and a uniform decorative finish are priorities—such as on driveways, garden paths, or permeable patio floors. Skipping proper blending can lead to weak spots or discolouration over time.
