How Do I Calculate Resin Per Square Metre?

← Back to With 1 kg of resin, how many square meters can you cover?

Accurately estimating how much resin you’ll need per square metre helps avoid waste and ensures a smooth project, whether you’re sealing floors, coating worktops or creating art pieces.

Basic Formula for Resin Calculation

To work out your resin needs, multiply the intended thickness (in millimetres) by the area (in square metres) to find the required resin volume in litres. As a rough guide: 1 mm thickness over 1 m² requires roughly 1 litre (approximately 1 kg) of mixed resin. For example, covering 2 m² with a 2 mm thick layer would use around 4 kg of resin.

• Resin needed (kg) = Area (m²) × Thickness (mm)

Check Product-Specific Coverage

Always consult your chosen product’s technical guidance for precise coverage. For instance, the Resinstone resin covers approximately 40–60 g per m² depending on the substrate and application. Countertop kits such as the Stone Effect Collection state recommended area coverage per kit size, so compare these against your project’s square metres.

Tips for Accurate Estimation

• Measure your area carefully, allowing a little extra for edges or absorption.
• Decide on an appropriate layer thickness matching your intended use (thicker for floors, thinner for art coatings).
• Refer to each product’s datasheet for guidance, especially for non-standard surfaces.
