Epoxy Flooring Calculator

Estimate coverage units across multiple coats using the selected coating’s declared coverage per kit or container.

By Alish Gautam, Software Developer · Updated · Calculation methodology

Start with the editable example below. Dimensions retain their physical size when units change. Region sets currency labels without converting currencies; confirm entered quotes after changing region.

Floor surfaces to coat

Use non-overlapping rectangles. Enter openings as area on the surface they interrupt.

Whole packages round up. Allowance is separate from purchased surplus. Prices omit labor, delivery, tax and other items unless explicitly entered.

Coverage depends on film thickness, substrate and product. Different primer and finish products must be estimated separately; this tool does not infer solids or dry film build.

How it works

Total coated area = net floor area × coats. Units = ceil(total coated area × (1 + allowance) / coverage per unit).

Assumptions and limitations

Coverage depends on film thickness, substrate and product. Different primer and finish products must be estimated separately; this tool does not infer solids or dry film build.

Whole packages round upward after the chosen allowance. Physical geometry and purchase reserve are separate. Manufacturer and project specifications override editable examples; the selected region does not establish a local code requirement.
