Coating Failure
Coating failure occurs when a protective coating system no longer performs as intended. This can result in loss of adhesion, cracking, blistering, or premature corrosion. Common causes include inadequate surface preparation, improper application, or challenging operating conditions.
Where does coating failure occur?
Coating failure can occur on any steel structure exposed to demanding environmental conditions, including:
- Oil & Gas – pipelines, storage tanks, and offshore structures.
- Petrochemical & Chemical – vessels and piping systems.
- Marine & Offshore Wind – ship hulls, ballast tanks, and turbine foundations.
- Infrastructure & Energy – bridges, cranes, and power plants.
For you as an asset owner, coating failure means unplanned maintenance, higher repair costs, and reduced asset lifespan.
Extra explanation and common causes
Typical forms of coating failure include:
- Loss of adhesion – caused by insufficient surface cleanliness or an inadequate surface profile.
- Blistering – caused by trapped moisture or contamination beneath the coating.
- Cracking – resulting from stress, temperature fluctuations, or incorrect coating thickness.
- Underfilm corrosion – when corrosion spreads beneath the coating layer.
- Delamination – when individual coating layers separate from one another.
Standards such as ISO 4628 provide guidance for the assessment and classification of coating defects.
Pinovo and coating performance
Pinovo’s dust-free vacuum blasting technology helps reduce the risk of coating failure by:
- Achieving Sa 2½ surface cleanliness and the required surface profile.
- Preventing contamination from dust and abrasive media.
- Enabling parallel operations, allowing coatings to be applied sooner and reducing exposure to weather conditions.
- Delivering consistent quality across prepared surfaces.
