Coating Failures
A coating failure occurs when a protective coating does not perform as intended, leading to loss of adhesion, cracking, blistering, or premature corrosion. Failures often result from improper surface preparation, incorrect application, or harsh operating conditions.
Where do coating failures occur?
Coating failures can appear on any steel asset exposed to demanding environments:
- Oil & gas – pipelines, storage tanks, offshore structures.
- Petrochemical & chemical plants – vessels and piping systems.
- Marine & offshore wind – ship hulls, ballast tanks, turbine foundations.
- Infrastructure & energy – bridges, cranes, power plants.
For you as an asset owner, coating failures mean unexpected maintenance, higher repair costs and reduced asset life.
Extra explanation and common causes
Typical coating failures include:
- Poor adhesion – caused by insufficient blast cleanliness or roughness.
- Blistering – trapped moisture or contaminants under the coating.
- Cracking – due to stress, thermal cycling, or coating thickness issues.
- Rust undercutting – when corrosion spreads beneath the coating film.
- Delamination – multiple coating layers separating from each other.
Standards such as ISO 4628 describe how to assess and categorize coating breakdowns.
Pinovo and coating performance
Pinovo’s dust-free blasting reduces the risk of coating failures by:
- Achieving Sa 2½ blast cleanliness and correct micron profile.
- Preventing contamination from airborne dust and grit.
- Allowing parallel work so coatings can be applied faster, reducing exposure to weather.
- Delivering consistent quality across all prepared surfaces.
