Fixing The Problems Left Behind By Other Applicators
-
Coating failure can occur for many reasons but they can be grouped into five categories:
1) Incorrect Coating Selection
2) Poor Surface Preparation
3) Error in Application/Curing or Mixing of the Coating
4) Manufacturer Formulation Error
5) Faulty Equipment Design or Operation Ar-Tech gets the call to remedy field failures caused by inexperienced applicators.

• Ensuring proper due diligence in coating selection.
• The importance of Surface Preparation and how contamination can cause Blistering and Delamination. A white blast alone cant eliminate salts and it is necessary to clean and test for them.
• Achieving proper mil thicknesses is crucial. Too thin a coat, may cause film breakdown and pinpoint corrosion.
• Excessive thickness will create internal stresses and crack, especially epoxies. Insufficient curing occurs as the coating exterior cures faster, creating a skin that entraps solvent leading to early failure.
• Sharp edges, welds, blind areas, and protrusions are common areas for coating failure and require appropriate finishing and application.
