Paint thickness, or dry film thickness, refers to the single layer or multiple layers of a coating’s thickness. Coatings protect substrates from corrosive conditions, offer cosmetic improvements, and can help prolong the life of industrial equipment. Applications may require specific coating thickness measurements so it’s important to reference industry standards and suggestions for the best results when applying coatings. Failure to properly applying coatings can lead to premature coating failure, costly repairs, and coating imperfections.
