How Is Resin Quantity Determined for Flowstone Floors?

← Back to How to calculate epoxy resin quantity?

Accurately working out the amount of resin required for Flowstone floors is essential for a seamless, durable, and cost-effective installation. Here’s how to approach it efficiently.

Understand the Main Factors

Determining resin quantity starts with two key pieces of information: the surface area of your project and the desired thickness of the resin-bound stone layer. The larger the surface or deeper the layer, the more resin you’ll need. If you’re planning a typical permeable outdoor floor, ensure you measure your space carefully and decide on the exact thickness recommended for your chosen stones and use case.

Practical Calculation and Tips

Most Flowstone kits provide a guide that lists recommended resin amounts per square metre for a typical application thickness (often between 12–18mm for driveways or footpaths). To calculate, simply multiply your surface area (in square metres) by the resin quantity per square metre as suggested in the kit’s instructions. It’s always smart to allow a small margin for spillages or uneven surfaces.

Measure your surface (length × width, in metres).
Refer to the kit guide for the exact resin usage per m² for your aggregate type and thickness.
For white stones, polyurethane binder is advised; for coloured stones, low-yellowing epoxy offers long-term colour retention.

When Resin Quantity Calculation Really Matters

Exact resin measurements are crucial if you want a robust, long-lasting permeable floor that drains properly and remains free of weak spots. Ensuring you have the correct resin amount reduces costs and minimises risk of patchy coverage, which is particularly important for paths, patios, and driveways subject to foot or vehicle traffic.
