Assumptions and estimates

  • Use manufacturer coverage for one coat and the actual net surface area. Absorbency, colour change and application losses vary; tin count rounds up.
  • Method: Litres = surface area × coats ÷ coverage × allowance factor. Whole tins round up.
  • Use actual product coverage. Absorbency, colour changes and application technique affect usage.
