If you’re planning to coat, refurbish, or create a decorative surface spanning 7 m², understanding exactly how many kilograms of epoxy resin are needed is essential for quality results and budget control. This guide explains how to calculate resin requirements, highlights key coverage differences between application types, and introduces trusted kits and binders for surfaces from countertops to pebble floors.

Understanding Epoxy Resin Coverage and Key Differences

Epoxy resin coverage depends on both the product formula and the intended use—coating thinly on a countertop, binding aggregates for permeable floors, or pouring into moulds for castings. Generally, thinner coatings require less resin per square metre, while thicker or textured applications may significantly increase your needs. Products like the “Stone Effect Collection” – Marble Epoxy Resin Countertop Kit are tailored for accurate area coverage, while solutions such as “Trasparente” – Epoxy Binder for Coloured Pebbles and Grits and “Flowstone” – Complete Permeable Floor Kit with Pebbles and Resin are optimised for different aggregate and surface finishes. Choosing the right type ensures the balance between performance and efficient use of resin for your 7 m² project.

Epoxy Resin Coverage Visualised

Most epoxy resins cover 1m² per 1–1.2kg at 1mm thickness, but this varies for pebble binders, countertop kits, and deeper pours. Always check your selected product for exact yield based on the effect or finish required.

“Stone Effect Collection” – Marble Epoxy Resin Countertop Kit

For those transforming kitchen worktops or bathroom vanities, the “Stone Effect Collection” – Marble Epoxy Resin Countertop Kit offers complete convenience with self-levelling resin and all necessary pigments, dyes, tools, and isopropyl alcohol. Each kit is carefully portioned for specific coverage, with sizes suitable for areas from 1 m² up to 8 m². For a 7 m² surface, opt for the 14 kg or 16 kg kit to ensure even coverage, professional marble or stone finishes, and lasting durability.

Self-levelling crystal-clear resin delivers an impeccable finish that smooths out minor surface flaws, while the kit’s coverage precisely calculated feature means you order exactly what you need, with no waste or surprise shortfalls. The included instructions also guide on correct layer thickness for optimal results.

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

If your goal is to refresh an outdoor surface such as a driveway, path, or patio, the “Flowstone” – Complete Permeable Floor Kit with Pebbles and Resin provides a resin-aggregate system calculated by area. The kit includes the right amount of resin and pebble to cover from small to very large areas; for 7 m², simply select the kit that matches your square metre requirement. The included guidance ensures correct mixing ratios and binder type for either white or coloured aggregates, preventing both product and budget wastage.

Permeable solution technology allows water drainage, ideal for the UK’s weather. Simple application and customisable finish options make it suitable for D.I.Y. and professional resurfacing projects.

“Trasparente” – Epoxy Binder for Coloured Pebbles and Grits

For decorative permeable floors requiring vibrant and lasting colour, “Trasparente” – Epoxy Binder for Coloured Pebbles and Grits offers a low-viscosity, UV-stable resin that fully impregnates selected aggregates. Typically, a mixing ratio of about 3% resin by weight is used for binding stones—so for every 25 kg of aggregate, you will require 750g of resin. Multiply this by the amount of aggregate needed to cover 7 m² at your desired layer depth for accurate ordering. Step-by-step guides are included for D.I.Y. and professional use.

Crystal-clear epoxy resin and low viscosity features make this binder a reliable choice for walkways, paths, and contemporary deck areas.

“Trasparente” – Multipurpose Clear Epoxy Resin for Casting (Up to 2cm)

If you need a protective or decorative clear coat, or wish to pour a layer up to 2 cm thick, “Trasparente” – Multipurpose Clear Epoxy Resin for Casting – Up to 2cm is the recommended choice. Its ultra-clear formula is suitable for large projects; coverage will depend on your layer thickness—around 1.1–1.2 kg per m² per mm thickness is typical. For a 2 mm surface layer on 7 m², expect to need roughly 15–17 kg in total, factoring in mixing, spillage, and substrate absorption.

The kit contains integrated UV filter and all basic tools for immediate application, supporting both artistic and functional creations.

Tips for Accurate Calculation and Resin Efficiency

For best results, always check your product’s technical guidance for precise coverage rates, as different surfaces absorb resin at different rates. When working with textured substrates or pebbles, extra resin may be required to fully coat and bind aggregates. Consider ordering a small surplus to account for unexpected absorbency or application errors. Use step-by-step coverage calculators—often provided with resin countertop kits and epoxy binders—to fine-tune your ordering. If your project area approaches the upper range of a kit, round up to the next size for stress-free application.

Application Insights: Surfaces and Results

Select the kit or binder that aligns with your project type: textured floors and aggregate mixes require more resin by volume than smooth countertop coatings. Choose a resin designed for your surface and aesthetic to ensure durable, beautiful results for your 7 m² project.
