Coating Failure

Coating failure occurs when a protective paint or coating system no longer provides the intended protection against corrosion, chemical attack, or mechanical damage. Failures can appear as blistering, flaking, rust breakthrough, or delamination.

Where does coating failure occur?

Coating failures are common in:

• Oil & Gas – offshore risers, flare booms, topside piping.
• Petrochemical & Chemical plants – process vessels, reactors, insulated pipelines.
• Marine & Offshore wind – deck areas, turbine towers, hull details.
• Infrastructure & Power – bridges, cranes, boilers, turbines.

For you as an asset owner, coating failure means higher maintenance costs, unplanned downtime, and faster corrosion progression.

Extra explanation

Causes of coating failure include:

• Poor surface preparation – inadequate blasting (not Sa 2½).
• Incorrect coating selection – mismatch with environment (ISO 12944 categories).
• Application errors – wrong thickness, curing or weather conditions.
• Mechanical stress – impact, abrasion or vibration.
• Chemical exposure – solvents, acids or seawater intrusion.

Consequences:

• Premature corrosion and reduced asset life.
• Higher lifecycle costs due to recoating or repair.
• Safety and environmental risks from leaks or spills.

Pinovo and coating failure prevention

Pinovo helps prevent coating failures by:

• Delivering Sa 2½ or Sa 3 blast cleanliness as required by ISO 8501 and NORSOK M-501.
• Achieving consistent micron roughness for coating adhesion.
• Enabling blasting in ATEX zones safely and dust-free.
• Capturing all debris so no contamination affects coating quality.

Pinovo does not supply coatings, but ensures your substrate is perfectly prepared for long-lasting protection.
