Understanding how much epoxy resin you need for 1 square metre is crucial to avoid overspending or running short mid-project. Whether you’re pouring a dining table, resurfacing worktops, or bonding decorative aggregates, this guide helps you estimate quantities for any resin thickness or finish. Ideal for DIYers, professionals, and anyone planning resin projects of any scale, you’ll also discover which ResinPro product matches your specific needs.

How Much Epoxy Do You Need Per Square Metre?

The main factor in determining epoxy resin needs is your required thickness: thin coatings need less, thick castings or pebble binding require more. For a standard 1mm coating, you’ll need approximately 1kg of mixed resin per square metre. For thick castings (like river tables), needs rise quickly—at 10mm depth, expect around 10kg per square metre. With pebble or stone aggregates, binder amounts depend on aggregate size and application, but often start around 8–12kg per square metre for standard depths. Choosing the right resin also depends on your intended finish, UV exposure, abrasion, or suitability for food-safe uses.

Visualising Epoxy Coverage per Square Metre

One kilogram of epoxy resin covers about one square metre at 1mm thickness. Visualise your project’s area and intended resin depth before choosing your kit. For example, a 10mm pour over 1m², such as a river table, would need roughly 10kg of resin. For pebble floors, amount required varies by aggregate thickness; always measure both area and intended layer depth for accuracy.

STONE EFFECT COLLECTION – Marble Epoxy Resin for Countertops

If you are resurfacing a kitchen worktop or bathroom countertop, the “Stone Effect Collection” – Marble Epoxy Resin Countertop Kit is a ready-to-use solution. The kit’s contents and instructions are meticulously calculated according to the area covered (1–8 m²), making estimation and planning simple. For a typical 1m² area, you simply choose the corresponding kit size for your thickness. This product is self-levelling, mask minor surface imperfections, and completes the aesthetic with pigments and alcohol for marble effects, eliminating guesswork when measuring resin for seamless coverage.

EpoxyTable 5-Five – Deep Pour Epoxy Resin (up to 5cm)

For projects where a thicker pour is the goal—such as river tables or artistic castings—the “EpoxyTable 5-Five” – Deep Pour Epoxy Resin for Tables and Large Projects – Up to 5cm is purpose-built. If you’re casting a river table with a 5cm deep channel over 1m², you’ll require about 50kg of resin. Precise calculation becomes indispensable at these depths to ensure structural integrity and perfect clarity. This resin offers long working time and is engineered to minimise yellowing and bubbles, vital attributes in large pours where resin performance can make or break the outcome.

Epoxytable 10-Ten – For Ultra Deep Pours (up to 10cm)

When your design calls for very deep castings—like thick, layered resin art or extra-deep tables—“Epoxytable 10-Ten” – Deep Pour Epoxy Resin for Tables, Up to 10cm Casting matches the task. With casting capability up to 10cm per layer, a 1m² pour at this depth requires approximately 100kg of resin. This advanced formulation is designed to avoid excessive heat, stay crystal clear, and resist yellowing for large, showcase pieces.

Trasparente – Epoxy Binder for Coloured Pebbles & Grits

For vibrant flooring using pebbles or decorative grits, “Trasparente” – Epoxy Binder for Coloured Pebbles and Grits ensures strong, UV-stable results. Resin quantity depends mainly on aggregate size and depth. For example, securing 1m² of pebbles at a 15–20mm depth typically requires 8–13kg of binder. The resin is low-viscosity for even coverage, non-toxic after curing, and specifically crafted to minimise yellowing from sunlight exposure, making it ideal for both indoor and outdoor decorative projects.

Tips for Calculating Epoxy Needs and Project Success

Start by measuring the area and multiplying by desired thickness (in metres) to get the required volume in litres (1 litre ≈ 1kg for epoxy). Always round up your estimate to allow for minor losses during mixing and pouring. When working with aggregates, consult product instructions or use online calculators for accurate binder-to-aggregate ratios. Finally, match your intended use—sealing, encapsulation, or binding—to a product designed for the thickness, clarity, and environmental resistance you need.

Practical Advice for Resin Quantity Planning

Always prepare slightly more resin than calculated to account for mixing losses and uneven surfaces. If in doubt, choose a kit sized for a slightly larger area than your project. Use gloves and appropriate mixing tools to maximise coverage and quality in your final result. For deep or complex pours, layering in stages avoids overheating and ensures a flawless finish.
