Coating thickness or as it is sometimes otherwise referred as Dry film thickness (DFT) is probably the most important measurement that is made when applying and inspecting protective coatings.

Coatings are designed to perform their intended function when applied within a tight DFT range as specified by the manufacturer. Correct thickness guarantees the highest product performance.
