Paint Coverage at 78% paint coverage transfer efficiency: a worked example

What does the result look like when paint coverage transfer efficiency reaches 78%? The full calculation is worked below with real intermediate numbers. ordering coating and scheduling paint booth capacity for attachment production

The inputs for this scenario

  • Paint Coverage covered amount: 1,180 units (unchanged)
  • Paint Coverage use per unit: 0.02 units (unchanged)
  • Paint Coverage transfer efficiency: 78 % (raised for this scenario; the documented default is 68)

Working through the calculation

  • Applying the documented formula (Theoretical coating at film build = painted attachment surface area × coating use per square foot) to the inputs above produces each figure below.
  • At this operating point the engine returns 27.23 gal for coating required for attachments, the number this scenario is built around.
  • At this operating point the engine returns 21.24 gal for theoretical coating at film build.
  • At this operating point the engine returns 5.99 gal for coating added for overspray and waste.
  • At this operating point the engine returns 78 % for spray transfer efficiency.

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 12.82% below the baseline at 27.23 gal.
  • A figure at this level is achievable when paint coverage transfer efficiency is genuinely sustained, not just peaked for a shift. Transfer efficiency varies widely with spray method, part geometry, and operator skill; the single percentage used here is an average, and complex shapes with deep recesses will lose more.

Results at a glance

  • coating required for attachments: 27.23 gal (headline result)
  • theoretical coating at film build: 21.24 gal
  • coating added for overspray and waste: 5.99 gal
  • spray transfer efficiency: 78 %
