Construction Machinery & Attachments worked example

Paint Coverage at 49% paint coverage transfer efficiency: a worked example

This worked example runs the paint coverage numbers for a tougher week than the baseline: 49% paint coverage transfer efficiency instead of the typical 68%. Estimate coating quantity for construction attachments from painted area, film build, and transfer efficiency.

The inputs for this scenario

  • Paint Coverage covered amount: 1,180 units (held at the documented default)
  • Paint Coverage use per unit: 0.02 units (held at the documented default)
  • Paint Coverage transfer efficiency: 49 % (the input this scenario stresses; the baseline uses 68)

Working through the calculation

  • The calculation starts from the formula this tool documents: Theoretical coating at film build = painted attachment surface area × coating use per square foot.
  • coating required for attachments works out to 43.35 gal at these inputs, and this is the headline figure for the scenario.
  • theoretical coating at film build works out to 21.24 gal at these inputs.
  • coating added for overspray and waste works out to 22.11 gal at these inputs.
  • spray transfer efficiency works out to 49 % at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where paint coverage transfer efficiency sits at 68% and the headline result is 31.24 gal, this scenario comes in 38.78% above the baseline at 43.35 gal.
  • Use it when ordering coating for a batch of attachments, quoting a paint job, or estimating waste from a given spray method. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • coating required for attachments: 43.35 gal (headline result)
  • theoretical coating at film build: 21.24 gal
  • coating added for overspray and waste: 22.11 gal
  • spray transfer efficiency: 49 %
