If you’re planning a project using resin—whether for pebble floors, marble effect countertops or river tables—knowing how many kilograms of resin you need per square metre is crucial to achieve a professional, lasting finish and avoid costly waste. This guide compares the most popular resin kits and binders for various surface types, showing how much resin to order per area, how thickness and substrate affect coverage, and which product best suits your project style.

Resin Coverage: How Much Do You Need Per Square Metre?

Coverage requirements for resin differ based on application, thickness, surface material, and decorative effect. For pebble flooring, you’ll need a careful mix of resin and aggregate, typically calculated as a weight ratio per area. Countertop kits are pre-measured for precise square metre coverage, while table projects depend on casting depth and wood-to-resin ratios. Below, we outline the key differences so you can estimate resin requirements with confidence and select the kit that matches your project’s scale and surface type.

Visual Comparison: Resin Coverage by Surface Type

Understand the differences: Permeable pebble systems require more resin per m² than surface coatings or thin-cast projects. Countertop kits are tightly calculated for a sleek, seamless finish, while bespoke tables and art castings depend on fill depth and substrate volume.

Always begin by measuring your area and noting specific instructions for each kit or resin type.

“Flowstone” – Complete Permeable Floor Kit with Pebbles and Resin

The “Flowstone” – Complete Permeable Floor Kit with Pebbles and Resin is designed for driveways, footpaths, patios and outdoor spaces where water drainage matters. This kit includes both aggregates and resin, and calculates quantities by square metre for easy planning. For coloured aggregates, use the kit’s low-yellowing epoxy; for white stones, non-yellowing polyurethane keeps the look bright and fresh. Typical usage is indicated in the kit—ensuring you get the right balance of resin and pebbles per m² for long-lasting, puddle-free surfaces. If you want a permeable, decorative floor with all components delivered and matched, Flowstone is the ready answer.

“Stone Effect Collection” – Marble Epoxy Resin Countertop Kit

The “Stone Effect Collection” – Marble Epoxy Resin Countertop Kit is ideal for those looking to upgrade kitchen or bathroom worktops without removal. Each kit is carefully tailored to cover between 1–8 square metres, giving you exact resin quantities required for the selected surface. The system is self-levelling, and included pigments, dyes, and tools ensure both experienced makers and DIYers achieve deep colour and realistic marble veining. To calculate how many kilograms of resin you’ll need, simply select your desired area when ordering—the kit does the rest.

“River-Table” – Complete Kit for Creating Your First Epoxy Resin Table

Planning a river table or similar casting project? The “River-Table” – Complete Kit for Creating Your First Epoxy Resin Table provides everything needed for beginners and enthusiasts. These kits base their resin quantities on a classic river table layout—typically 2/3 wood, 1/3 resin—with comprehensive instructions and details, so you know exactly how much resin is required for various casting depths (2 cm or 5 cm per application). It’s vital to calculate the total casting volume of your design; kits are sorted to group similar surface and depth requirements, so you can pick confidently and ensure full coverage with no shortfall.

“Trasparente” – Epoxy Binder for Coloured Pebbles and Grits

If you’re seeking a specialist resin binder for decorative aggregate floors featuring coloured or dark pebbles, “Trasparente” – Epoxy Binder for Coloured Pebbles and Grits is made for the job. Coverage will depend on aggregate size and application thickness, with guidelines typically suggesting 400–800g of resin per 20–25kg of aggregate. This translates to a variable kilogram-per-square-metre ratio, so it’s perfect for custom or larger professional jobs. The transparent, UV-resistant formula ensures enduring clarity and colour integrity on exposed aggregate installations up to 2 cm thick.

Quick Tips for Calculating Resin Per Square Metre

To calculate the right amount of resin for any project, always measure your surface accurately and decide your required thickness. Check manufacturer or kit guidelines for resin-to-aggregate ratios if you’re using pebbles or grits. Ordering a little extra is sensible to account for absorption or unseen surface texture, and always match the correct resin to the colour and use case for lasting, weatherproof results.

Expert Advice for a Flawless Finish

Top tip: When in doubt, order slightly more resin than calculated—this covers substrate absorption and minor spills. For pebble floors, match resin to your chosen aggregate’s shade for lasting visual appeal.

Avoid mixing different resin types on a single project; stick to the recommended product for the best UV resistance and finish quality.
