Choose a Coating or Resin Tool
Resin and epoxy projects often fail because the material quantity is underestimated (or the mix ratio is off). Our calculators are designed to give you project-ready estimates based on area and thickness, with guidance on common real-world factors like waste, surface porosity, and kit sizing.
We publish our assumptions and update tools as standards and product specs evolve. You can review our Methodology, Data Sources, and Review Board pages for transparency.
Epoxy Calculator
Estimate epoxy needs for thin-film coatings or self-leveling applications by area and thickness.

- Confirm product specs: coverage rates and mix ratios vary by brand and system.
- Measure the true area: include edges, returns, and any vertical faces you plan to coat.
- Plan for waste: mixing cups, roller loss, and leftover material can add up.
- Surface prep matters: contamination, moisture, and porosity can change coverage and adhesion.
- Follow safety guidance: use ventilation and appropriate PPE per the product label/SDS.
If you’re unsure about a system for structural or heavy-use areas (commercial floors, load-bearing surfaces, etc.), consult a qualified professional or the product manufacturer’s technical documentation.
Important Estimate Disclaimer
Calculator results are general estimates only. Actual resin/epoxy needs may vary based on surface porosity, application technique, temperature/humidity, substrate condition, and product-specific coverage rates and mix ratios.
Always verify manufacturer specifications before purchasing or mixing materials, and follow safety instructions and local regulations. For critical applications, consult a qualified professional.
