Understanding how much area one litre of resin can cover is essential for planning your flooring or surface coating project efficiently and cost-effectively. This guide compares various resin types—including methacrylic, epoxy, polyurethane coatings, and water-based floor primers—to help you select the right product for your concrete, pebble, or multi-surface applications.

Resin Coverage Comparison: Square Metres Per Litre

The coverage of resin per litre varies greatly depending on the type of resin, the nature of the substrate, and the application method. Here’s a comparison:

• Methacrylic resin (e.g., “Resinstone”): Designed for highly absorbent concrete. One litre covers approximately 16–25 m² (at 40–60 g/m² consumption).
• Epoxy binder (e.g., “Trasparente”): Coverage depends on mixing ratio with aggregate. With pebble floors, one litre typically mixes with a specific volume of stones, influencing coverage.
• Polyurethane coating (e.g., “Prolux”): For non-absorbent surfaces like tiles or metal, coverage is around 6.9 m² per litre (145 g/m² consumption).
• Water-based epoxy primer (e.g., “Epoxyprimer”): Coverage ranges from 3.3–10 m² per litre (100–300 g/m²), varying with substrate porosity.

Visualising Resin Coverage

See real project examples showing different resin types applied on driveways, pebble floors and industrial surfaces. These visuals highlight the look and finish each product achieves for specific square metre coverage.

“Resinstone” – One-Component Methacrylic Resin for Concrete Floors and Driveways

If you need a sealer for concrete floors or driveways, “Resinstone” – One-Component Methacrylic Resin for Concrete Floors and Driveways offers deep capillary penetration and robust waterproofing for indoors and out. The theoretical consumption is only 40–60 g/m²: this means one litre of RESINSTONE can cover between 16 and 25 m² on properly prepared, absorbent concrete. This makes it highly efficient for large surface areas that require lasting protection against moisture, UV, and wear.

The quick-drying formula allows return to use in under 12 hours—ideal for homes, garages, patios, and stamped driveways. Do note: Actual coverage can vary slightly depending on the concrete’s porosity and application method.

“Trasparente” – Epoxy Binder for Coloured Pebbles and Grits

“Trasparente” – Epoxy Binder for Coloured Pebbles and Grits is formulated for creating vibrant, UV-resistant pebble or aggregate floors. Unlike pure coatings, this binder is mixed thoroughly with pebbles or gravel first, making coverage per litre contingent on the depth and area of your decorative aggregate layer.

For a typical permeable pebble floor, the recommended mixing ratio ensures all stones are encapsulated for strength and clarity. Use the resin and stone calculator on the product page to estimate your coverage for driveways, garden paths, or decorative surfaces. As a guide, 1 litre often suffices for several square metres at standard layer thickness, but always verify with project-specific calculations and aggregate size.

“Prolux” – PU Coating for Tiles, Concrete, Plastic, and Metal – Suitable for Driveable Surfaces

For premium protection on smooth, non-absorbent surfaces like ceramic, concrete, plastic, or steel, “Prolux” – PU coating for tiles, concrete, plastic and metal – suitable for driveable surfaces delivers outstanding wear and weather resistance. Its two-component polyurethane formula covers approximately 145 g/m², translating to about 6.9 m² per litre in a single even coat. This high-yield finish is available in gloss or satin and is certified for demanding environments including parking areas and workshops.

Remember, the actual yield depends on surface smoothness and preparation—unprepared or rough surfaces will absorb more product, reducing coverage per litre.

“Epoxyprimer” – Universal Water-Based Two-Component Epoxy Floor Primer

If preparing your substrate is vital, “Epoxyprimer” – Universal Water-Based Two-Component Epoxy Floor Primer maximises bond and durability for subsequent resin layers. Its consumption (100–300 g/m²) means one litre can span 3.3–10 m², depending on how porous or open the surface is. It is highly recommended for artists, DIYers, and professionals working on varied surfaces—concrete, timber, screed, or ceramic—requiring secure adhesion and eco-friendly, odourless performance.

Allow 24–48 hours for curing before overcoating and adjust expectations based on substrate type and site conditions.

Key Factors Affecting Resin Coverage

The precise area that one litre of resin will cover depends on surface porosity, product type, and target thickness. Highly absorbent surfaces like bare concrete consume more resin, while sealed or non-absorbent substrates yield maximum coverage. Always prepare your substrate thoroughly, use recommended application tools, and reference the product’s technical data before calculating your requirements.

Expert Tips for Estimating Resin Usage

Always consult each product’s technical data for recommended consumption. If unsure, test a small area first — surface porosity and application conditions influence actual yield. Plan for a 10–15% margin above theoretical coverage to accommodate wastage.
