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 (Substance used for decorating or protecting a surface, sometimes referred to as coating), the applicator can calculate the required wet film thickness at which the paint (Substance used for decorating or protecting a surface, sometimes referred to as coating) must be applied.

• The protective coatings (Paint - substance used for protection of surfaces ie steel from corrosion.) applicator should be able to calculate the wet film thickness of most applied coatings (Paint - substance used for protection of surfaces ie steel from corrosion.).
• Most coatings (Paint - substance used for protection of surfaces ie steel from corrosion.) 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.
