Resin Bound Gravel Kit Size & Surface Area Explained

← Back to How much does a resin bound gravel kit cost?

When planning a resin bound gravel installation—whether for a driveway, pathway, or decorative garden feature—it’s essential to select the right kit size. Understanding how kit sizes correspond to surface area ensures you achieve seamless coverage and an attractive finish without excess waste or shortage.

How to Choose the Right Kit Size

Resin bound gravel kits are typically sold according to the area they cover, with kit sizes ranging from single paving stones to full driveways. Standard kit estimates are generally based on a specified thickness (commonly 15–20mm) and assume use with washed and dried stones. As a rough guideline, 1.44 m² at 20 mm thickness may require around 13 kg of binder resin to securely bond approximately 432 kg of aggregate. To tailor your purchase, measure the square metreage of your installation area, then check the product sizing chart or calculator provided by the kit supplier.

Considerations for Aggregates and Binders

The type of stone—white or coloured—determines the best binder resin for lasting results. For white stones, a polyurethane binder such as Polirock helps minimise yellowing, while coloured or natural aggregates pair well with a clear epoxy binder like “Trasparente”. Always mix the resin thoroughly with clean, dry aggregate; never pour resin directly over laid gravel, as proper bonding is only achieved with full mixing. Thickness and precise aggregate size can affect coverage—stick to the recommendations in your kit to ensure optimal performance.

When Kit Size Really Matters

• Driveways and patios: Accurate kit selection avoids patchy coverage and wasted material.
• DIY projects: Sizing kits by surface area takes the guesswork out for first-time installers.
• Budget planning: Knowing your required kit size makes it easier to estimate total project costs and avoid unexpected expenses.
