Lacquer Finish Cure Time at 7.2% booth and cure window allowance: a worked example

Suppose booth and cure window allowance falls to 7.2%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate cure time for a batch of instrument bodies, necks, or acoustic panels through spray, flash, and full cure before buffing.

The inputs for this scenario

  • Finishing batch size: 120 parts (held at the documented default)
  • Coats cleared per minute: 12 coats / min (held at the documented default)
  • Booth and cure window allowance: 7.2 % (the input this scenario stresses; the baseline uses 10)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base finish cure time = finishing batch size รท coats cleared per minute.
  • Required finish cure time works out to 10.72 hr at these inputs, and this is the headline figure for the scenario.
  • Base finish cure time works out to 10 hr at these inputs.
  • Booth and cure allowance applied works out to 7.2 % at these inputs.
  • Coats cleared per minute works out to 12 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where booth and cure window allowance sits at 10% and the headline result is 11 hr, this scenario comes in 2.55% below the baseline at 10.72 hr.
  • It converts a finishing batch size and a coat-clearing rate into base cure hours, then adds a booth and cure-window allowance to give required finishing hours. 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

  • Required finish cure time: 10.72 hr (headline result)
  • Base finish cure time: 10 hr
  • Booth and cure allowance applied: 7.2 %
  • Coats cleared per minute: 12 pieces / min
