Protective Coatings Application - Unit 5.3.1: Wet Film Thickness

Objective: To measure the wet film thickness of an applied coating. With a knowledge of the target dry film thickness and the volume solids of the paint, the applicator can calculate the required wet film thickness at which the paint must be applied.

  • The protective coatings applicator should be able to calculate the wet film thickness of most applied coatings.
  • Most coatings have a different wet film thickness from the dry film thickness.
  • Film thickness at applied stage can not be calculated without knowing the required wet, and ultimately, the dry film thickness.
  • The calculation and process is a simple method.
