Plan durable floors with precise epoxy paint material estimates for any site. Calculate coats, kit counts, mix ratio, waste, and budget quickly without guesswork.
Choose coverage-based or thickness-based estimating. Optional primer is included as additional liters before waste.
These examples illustrate typical commercial coating assumptions.
| Area | Coats | Coverage (m2/L) | Waste | Kit Size | Mix Ratio | Estimated Kits |
|---|---|---|---|---|---|---|
| 120 m2 | 2 | 6 | 10% | 15 L | 2 : 1 | 3 |
| 250 m2 | 1 | 5 | 12% | 20 L | 4 : 1 | 3 |
| 800 ft2 | 2 | 7 | 8% | 10 L | 2 : 1 | 3 |
Thickness-based coverage is theoretical. Substrate profile and application method can change real coverage.
Epoxy coatings are widely specified for garages, warehouses, showrooms, kitchens, corridors, and mechanical rooms because they form a dense, chemical-resistant surface. Quantity planning matters because delays often occur when material runs short mid-pour, or when mixed batches exceed the workable pot life and become waste.
Your estimate begins with accurate area measurement, then coats. A single maintenance coat may be enough for light service, while two coats are common for improved film build and uniform appearance. The calculator converts square feet to square meters, keeping coverage calculations consistent across projects.
Coverage-based estimating uses a published spread rate such as 5–7 m2 per liter per coat. Thickness-based estimating starts with specified dry film thickness and solids by volume to derive a theoretical coverage. Use coverage values when you have a tested rate for your substrate and method.
Solids by volume indicates how much of the wet application becomes the final dry film. Higher solids typically deliver better build per coat. If the specification calls for 100 microns DFT at 60% solids, theoretical coverage is about 6 m2 per liter, before site factors are applied.
Waste is not only spills. It includes material left in rollers, squeegees, buckets, and mixing pails, plus overlap at edges, cut-ins, and texture variations. For open slabs with efficient batching, 8–12% is common. For tight spaces or uneven substrates, 15–20% may be safer.
Two-part epoxies require correct component ratios to cure properly. The calculator splits purchased liters into Component A and Component B based on your ratio, supporting procurement and on-site staging. Always confirm whether the ratio is by volume or by weight on the product datasheet.
Projects usually purchase full kits, not partial liters. The calculator rounds up to the next kit to prevent shortages. Any surplus should be planned for touch-ups, repairs, and punch-list work, especially in high-traffic areas where minor defects become visible after cure.
Cost per square meter is a practical benchmark for budgeting and comparing alternatives. Exporting a CSV or PDF report supports submittals, takeoff records, and change-order discussions. Pair the estimate with surface preparation notes, primer requirements, and cure-time constraints for a complete plan.
Use the manufacturer’s spread rate for your system and application method. If unsure, start with 6 m2 per liter per coat for many floor epoxies, then adjust after a small test area.
Use thickness-based estimating when the specification defines dry film thickness and you know solids by volume. It is useful for compliance-driven work where film build is a controlled requirement.
Primer is optional. Select “Include Primer” and enter primer coats and primer coverage. The tool adds primer liters before applying the waste factor, then calculates total kits for purchase planning.
Extremely high waste often indicates incorrect coverage inputs or measurement errors. The limit helps prevent unrealistic results. If your site conditions truly generate high losses, increase waste thoughtfully and document the reasons.
No. Some products specify ratios by weight, especially when component densities differ. This calculator uses a volume split. If your ratio is by weight, convert using densities or follow the supplier’s packaging guidance.
Keep surplus for touch-ups, edge detailing, and future maintenance. Store components per label instructions and track batch numbers. Avoid mixing partial kits unless the product allows it and you can measure accurately.
Two-part systems are commonly sold as complete kits with fixed proportions. Rounding ensures you can mix properly without guessing ratios and reduces the risk of schedule disruption from last-minute procurement.
