Wet Film Thickness with target dry film thickness of 1 mils: a worked example

Suppose target dry film thickness falls to 1 mils. This page works the full calculation at that level so you can see exactly which result moves and by how much. Convert a dry film thickness target into the wet film thickness needed for a liquid coating.

The inputs for this scenario

  • Target dry film thickness: 1 mils (the input this scenario stresses; the baseline uses 2)
  • Wet film conversion factor: 2.08 x (held at the documented default)
  • Target wet film thickness: 4.2 mils (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Calculated wet film = dry film target × conversion factor.
  • Adjusted value works out to 2.08 wet mils at these inputs, and this is the headline figure for the scenario.
  • Gap to target works out to -2.12 value at these inputs.
  • Measured value works out to 1 value at these inputs.
  • Correction factor works out to 2.08 x at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target dry film thickness sits at 2 mils and the headline result is 4.16 wet mils, this scenario comes in 50% below the baseline at 2.08 wet mils.
  • It computes required wet film by multiplying target dry film by a conversion factor, then shows the gap to your wet film target. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Adjusted value: 2.08 wet mils (headline result)
  • Gap to target: -2.12 value
  • Measured value: 1 value
  • Correction factor: 2.08 x
