Coatings & Concrete Calculators

Estimate material quantities and get weather guidance for concrete pours and coatings applications.

Concrete Projects

Calculate cubic yards of concrete required. Enter dimensions, slab thickness in inches, waste allowance, and site conditions to get a verified volume estimate with weather guidance.

Coatings Projects

Calculate gallons or kits required for floor coatings, roof coatings, polyurea, waterproofing, and more. Thickness in mils. Includes DFT / WFT calculations and application weather guidance.

1 mil = 0.001 inch. Coating thickness is normally specified in mils (thousandths of an inch), not inches. Dry film thickness (DFT) and wet film thickness (WFT) are always expressed in mils on this calculator.

FILM THICKNESS (DFT / WFT)

All thickness values are in mils. DFT = dry film thickness. WFT = wet film thickness.

mils

Dry film thickness per coat, from the product TDS.

%

From the product TDS. Required to calculate WFT.

COVERAGE RATE & QUANTITY

Enter the coverage rate from the product TDS at the specified thickness. A published coverage rate applies only at the thickness stated — do not use it at a different mil thickness.

sq ft/gal

Use the coverage rate from the product TDS at the exact mil thickness you are applying. Coverage rates are thickness-specific — a rate published at 20 mils DFT does not apply at 10 mils DFT.
