How much resin and pebble do I need for my pool area?

← Back to What is the best permeable surface for pools?

When installing a permeable pool surround with pebbles and a UV stable resin, calculating the correct materials ensures a durable, low-maintenance surface that drains efficiently and looks professional. This quick guide helps you estimate what you’ll need for a 1.2 square metre project.

Coverage Guide for Resin-Bound Pebble Mixes

To achieve optimal strength and drainage for your pool area, material quantities must be matched to the intended thickness. For resin-bound pebble floors, a typical blend at 20 mm depth requires roughly 300–360 kg of washed pebbles and 9–11 kg of high-quality, UV stable resin binder for a 1.2 m² area. This ratio ensures every stone is evenly coated for stability and a smooth finish.
For white or light-coloured aggregates, a specialised polyurethane resin such as Polirock delivers long-term UV resistance and an anti-slip surface perfect for wet pool surrounds.

Mixing and Application Tips

Begin by making sure your chosen pebbles are washed and fully dry; damp stones can affect resin adhesion. Gradually add resin to your aggregate, mixing thoroughly until each pebble is coated before trowelling out the mix on your prepared substrate.
Always follow specific kit instructions for optimum results, and remember to allow each layer to fully cure before the area is open to foot traffic.

When Precise Quantities Matter

Getting the mix right is crucial for pool surrounds where safety, durability, and drainage are vital. Underestimating material amounts can lead to weak spots or uneven finishes, while overapplication wastes both product and money. Calculating for 1.2 m² ensures your surface remains attractive and functional, season after season.
