What You’ll Need

Before starting, gather the necessary materials and tools to ensure a smooth workflow and optimal results. Recommended products for resin-bound flooring include:

• “Flowstone” – Complete Permeable Floor Kit with Pebbles and Resin: A comprehensive system for creating permeable, draining outdoor surfaces.
• “Trasparente” – Epoxy Binder for Coloured Pebbles and Grits: A transparent binder for coloured and natural stone aggregates.
• “Epoxyprimer” – Universal Water-Based Two-Component Epoxy Floor Primer: Prepares and seals stable substrates including concrete, screed, or tiles.
• “Polirock” – Polyurethane Binder for White Stones, 2kg Two-Component Kit: Ensures clarity and UV resistance, ideal for white or light aggregates.

Additional tools: mixing vessel, paddle mixer, trowels, gloves, and protective gear.

Step 1: Prepare the Surface

Start by ensuring your base is load-bearing, stable, and free from moisture, dust, oil, or loose debris. Concrete, screed, or well-fixed tiles are ideal substrates. An uneven or damp substrate can compromise adhesion and lead to long-term surface failure.

Check for cracks or defects and repair them before proceeding. It’s vital to allow new concrete slabs to fully cure—typically 28 days—before resin application. The ambient and substrate temperature should be between 10°C and 25°C for best results. Avoid working in wet conditions or direct sunlight, which can affect curing and finish.

Always prepare and prime your floor substrate carefully for the best results and longevity of your resin floor.

Step 2: Apply the Primer

To enhance adhesion and seal the substrate against moisture, apply a suitable floor primer evenly across the prepared surface. Use a roller, brush, or spatula to achieve consistent coverage. Allow the primer to dry thoroughly as directed, typically for 24 to 48 hours.

For this stage, “Epoxyprimer” – Universal Water-Based Two-Component Epoxy Floor Primer is recommended on concrete, wood, or tiled bases, ensuring solid adhesion and an odourless application suitable for outdoor or indoor projects.

Step 3: Mix Resin Binder and Aggregates

Once the primer has cured, combine your chosen resin binder with dried decorative aggregates. The mixing ratio will vary depending on product and aggregate type—always follow the manufacturer’s instructions for both resin and stone.

For coloured or natural stones, “Trasparente” – Epoxy Binder for Coloured Pebbles and Grits provides strong bonding and clarity. If working with white or light-coloured stones, “Polirock” – Polyurethane Binder for White Stones, 2kg Two-Component Kit offers UV resistance and a non-yellowing finish.

Use a paddle mixer or cement mixer for larger batches to ensure even distribution. Poor mixing can result in weak spots or colour inconsistency.

Proper mixing of resin and aggregates is crucial for durability—take care to fully coat the stones with binder for best performance.

Step 4: Lay and Finish the Resin Flooring

Pour the prepared resin and aggregate mixture onto the primed floor in manageable sections. Using a steel trowel, spread the mix uniformly to achieve target thickness—commonly around 10–18 mm for footpaths and light traffic areas.

Press down to compact the mix and achieve a smooth surface. Attention at the edges and joins ensures a seamless final look. Some systems, such as the “Flowstone” – Complete Permeable Floor Kit with Pebbles and Resin, provide step-by-step instructions to support a consistent and attractive result across various project sizes.

Allow the surface to cure fully before subjecting to foot or vehicle traffic—cure times vary by product and environment but are generally 10–24 hours for light traffic, and up to 48 hours for full cure.

Use the right resin binder for your chosen stones to maintain appearance and structural integrity over time.

Tips, Common Mistakes and Troubleshooting

Successful resin flooring requires attention to detail and strict adherence to conditions and instructions:

Avoid applying resin in extreme temperatures or wet conditions to prevent poor curing or surface defects.

Do not skip priming or rush mixing. Incomplete mixing or using the wrong binder (e.g., epoxy with white stones) may result in yellowing, weak floors, or water ingress. Always check product compatibility and timing, and follow the guidance in your selected system.

If you spot dull patches after curing, check for insufficient resin coverage in those areas and consider a corrective thin overcoat. For stains or surface issues, address spills promptly and refer to manufacturer cleaning advice to maintain long-term appearance.
