How much binder resin do I need for a pebble floor?

Resin and Aggregate Quantities Explained

For a coloured aggregate floor covering an area of 1.44 m² at 20 mm thickness, you’ll require approximately 432 kg of stones and about 13 kg of binder resin. These proportions ensure the pebbles are thoroughly encapsulated, promoting long-term durability and a strong, even finish.

• Stones/pebbles: 432 kg for 1.44 m² at 20 mm
• Binder resin: 13 kg for 1.44 m² at 20 mm

Always mix the resin and stones together before laying for a consistent bond. Pre-weighed kits such as the “Flowstone” Complete Permeable Floor Kit make this process more straightforward, providing matched quantities for common project sizes.

Choosing the Right Binder Resin

Select a binder that’s compatible with your chosen aggregate. For coloured pebbles and grits, opt for a clear, UV-resistant epoxy like the “Trasparente” Epoxy Binder. This ensures the finished floor retains vivid colours and withstands outdoor conditions. Always follow the manufacturer’s installation instructions for best results and durability.

When Accurate Quantities Matter Most

Getting your proportions right is especially important for larger projects and visible pathways, where running out mid-installation can result in colour variation or uneven surfaces. Proper measurement not only ensures a neat appearance, but also saves on unnecessary waste and expense.
