Common Coating Defects and How to Prevent Them

Despite the best efforts, coatings can sometimes exhibit defects that compromise their performance and longevity. A NACE Certified Coating Inspector plays a critical role in identifying and preventing these defects. Let’s explore some of the most common coating defects and how they can be avoided:

Blistering

Blistering occurs when pockets of air or moisture become trapped between the coating and the substrate, causing the coating to lift or bubble. This defect can be prevented by ensuring proper surface preparation, including the removal of contaminants and moisture. A NACE Certified Coating Inspector checks for any signs of surface moisture or inadequate surface cleaning, which can contribute to blistering issues.

Peeling

Peeling is the detachment of the coating from the substrate, often resulting from poor adhesion. It can occur due to inadequate surface preparation, incompatible coating systems, or improper curing conditions. A NACE Certified Coating Inspector verifies that proper surface preparation techniques are followed, suitable coatings are applied, and the cure times and environmental conditions are maintained as per the manufacturer’s recommendations.

Inadequate Film Thickness

Inadequate film thickness can compromise the protective properties of coatings, leaving the substrate vulnerable to corrosion or other damage. A NACE Certified Coating Inspector measures the wet and dry film thicknesses during the coating application process to ensure that they meet the specified requirements.

Visual inspections can be performed using the naked eye or with the aid of magnification tools, such as magnifying glasses or microscopes, to identify even the smallest imperfections.

Wet Film Thickness Measurement

Measuring the wet film thickness during coating application is crucial to ensure that the desired dry film thickness is achieved. A NACE Certified Coating Inspector uses wet film thickness gauges, which are designed to measure the thickness of the coating while it is still wet. These gauges are placed on the wet coating and provide an instant reading, allowing the inspector to adjust the application technique if necessary to achieve the specified wet film thickness.

Dry Film Thickness Measurement

Once the coating has dried or cured, a NACE Certified Coating Inspector measures the dry film thickness to verify its compliance with the specified requirements. Electronic dry film thickness gauges are commonly used for this purpose. These gauges use magnetic or eddy current principles to measure the thickness of the coating without damaging it. The inspector takes multiple readings across the coated surface to ensure consistency and accuracy.

Adhesion Testing

Ensuring proper adhesion between the coating and the substrate is crucial for the coating’s performance and longevity. A NACE Certified Coating Inspector performs adhesion tests to assess the bond strength between the coating and the substrate. Various adhesion testing methods can be employed, including cross-cut tests, pull-off tests, or tape tests. These tests involve applying pressure or pulling force to evaluate the coating’s adhesion and determine if any areas require further attention.

Non-Destructive Testing (NDT)

Non-destructive testing methods are valuable tools for assessing the quality and integrity of coatings without causing damage. A NACE Certified Coating Inspector may utilize various NDT techniques, depending on the specific requirements of the project. These techniques may include magnetic particle testing, ultrasonic testing, radiographic testing, or thermographic imaging. NDT methods provide valuable insights into coating thickness, surface defects, delamination, or other hidden anomalies that may not be visible to the naked eye.
