How to Calculate Quantities for Resin-Bound Flooring

Planning a resin-bound or permeable floor but unsure how much material to order? Correctly estimating quantities is key for a smooth and hassle-free installation with minimal waste.

Working Out Coverage

Each resin-bound flooring kit or aggregate typically lists how much surface area it can cover. Always check the supplier’s guidance, as coverage varies depending on intended thickness and the type of stone or resin. For example, a complete kit like the Flowstone permeable floor kit is available in packs clearly marked by the square metres they’ll coat.

Measuring Your Space

To estimate how much product you’ll need, carefully measure your intended installation area in square metres (length × width). Take into account any irregular edges or shapes, and add a small margin for off-cuts or errors—especially if your area isn’t a perfect rectangle.

Calculate total area in m²
Check product info for recommended thickness and yield per kit or per 25kg of stone
If combining products, make sure both resin and aggregate quantities match your surface area needs

Practical Tips Before Buying

If in doubt, consult the manufacturer or supplier with your area measurements and the finish you’d like. Bespoke spaces may need tailored advice. Buying a little extra is wise for patching or touch-ups. Products like washed pebbles come in defined bag sizes, making it easy to calculate how many you need for your chosen thickness.
