If you’re planning a project with resin—whether for concrete floors, decorative pebble surfaces, or transforming your kitchen worktops—understanding exactly how much area 1 kg of resin will cover is essential. This guide compares leading ResinPro solutions to help you estimate resin quantity, plan your budget, and achieve professional results, whether you’re a DIY enthusiast or a contractor.

Resin Coverage at a Glance: What Influences Square Metres per Kilogram?

Resin coverage is influenced by three core factors: type of resin, intended use, and thickness of the applied layer. For example, sealing a concrete drive requires much less resin per m² than binding coloured pebbles or achieving a durable, marble-like countertop. Below, we outline key differences to help you select the most suitable resin system for your project and accurately estimate coverage.

• Coverage per kilogram varies by resin type and application thickness.
• Very thin surface sealers (e.g., for concrete or art surfaces) typically stretch further per kg than deep binding or pouring resins.
• Consider both surface absorption and target finish when calculating resin needed.

Visualising Resin Coverage

Use sample boards and test patches to visualise the finish and verify actual coverage. This ensures your resin layer thickness matches project requirements without waste or shortage.

“Resinstone” – Ideal for Concrete Floors and Driveways

The “Resinstone” – One-Component Methacrylic Resin for Concrete Floors and Driveways is formulated for sealing, protecting, and waterproofing concrete floors. Its application is highly efficient: the typical consumption is 40–60 g per m². This means 1 kg covers approximately 16–25 square metres when applied as recommended. This deep-penetrating formula is perfect for garages, yards, and outdoor paths where durable, breathable protection is vital.

“Stone Effect Collection” – For Marble Epoxy Countertops

The “Stone Effect Collection” – Marble Epoxy Resin Countertop Kit brings a transformative finish to kitchen and bathroom worktops. These all-in-one kits include all you need for a professional result, with coverage precisely calculated for 1–8 m² depending on kit size. Typically, 2.4 kg covers around 1 m² at a finish thickness prioritised for durability, equating to roughly 0.4 m² per 1 kg. This thicker application ensures a robust, long-lasting surface but means more resin is needed per metre than for thin sealing coats.

“Trasparente” – Epoxy Binder for Pebble and Grit Floors

The “Trasparente” – Epoxy Binder for Coloured Pebbles and Grits is purpose-built for decorative aggregate flooring like stone carpets or permeable driveways. The ratio of resin to aggregate and the intended thickness (often 10–20 mm) greatly changes how much area 1 kg will serve. As a general rule, substantial projects (e.g. 1.44 m² at 20 mm thickness) might require around 13 kg resin for 432 kg stones—so for these applications, coverage per kilo is far less (roughly 0.11 m² per 1 kg at such thickness). Use the Stones & Binder Calculator for best results on custom surfaces.

“Art Pro” – For Artistic Coatings and Thin Layers

“Art Pro” – Clear Epoxy Resin for Artists and Surface Coating is formulated for surface coatings (trays, coasters, decorative tops) where a thin, glossy layer is desired. At a 1.5–2 mm thickness, 1 kg typically covers about 0.5–0.7 m². As with all surface coatings, ensure the minimum recommended thickness is respected to maintain durability and clarity.

Tips for Calculating Resin Requirements

Always follow the manufacturer’s recommended application rates per square metre. Consider these points:

• Factor in application method—self-levelling resins and sealers have different yield compared to pebble binding resins.
• Account for surface texture and porosity, especially on absorbent materials like concrete or stone aggregate mixes.
• It is better to slightly overestimate than run short mid-project, particularly on larger continuous surfaces.

Practical Project Examples

Calculate your resin needs based on real project sizes—measure your intended surface accurately and select the resin system made for that specific use, like decorative pebbles, countertops, or floor sealing.
