Calculation method

Calculation method

Net coated area (m²)

Net=sum strips-excluded; paint=net×coats/coverage/(1-waste).

Paint required including waste (L)

Net=sum strips-excluded; paint=net×coats/coverage/(1-waste).

Assumptions & limits

Assumptions & limits

  • Measured area/label arithmetic; no coating compatibility or antifouling recommendation. Supported limits: All required fields must be finite values of the exact declared type and within displayed bounds. Lists contain1–1000 finite numbers. JSON tables are numeric rectangular rows, at most100 rows and30 columns; individual tools have stricter shape/domain constraints. Measured area/label arithmetic; no coating compatibility or antifouling recommendation.
