Coating inspection is the process of evaluating the quality and effectiveness of protective coatings applied to surfaces, such as metal, concrete, or wood. This inspection ensures that the coatings meet industry standards and specifications, which helps prevent corrosion, wear, and other forms of damage. Inspectors typically check for factors like thickness, adhesion, and uniformity of the coating. During a coating inspection, various tools and techniques are used, including dry film thickness gauges and adhesion testers. Inspectors may also conduct visual assessments to identify defects like bubbles, cracks, or discoloration. Proper coating inspection is essential for maintaining the longevity and performance of structures and equipment.
