Surface Preparation Problems
Poor surface preparation can leave mill scale, corrosion products, soluble salts, dust, oil, or inadequate surface profile. These issues reduce adhesion and can drive underfilm corrosion.
Application And Curing Issues
Incorrect film thickness, missed stripe coats, poor mixing, incorrect overcoating intervals, low temperature, high humidity, and poor curing conditions can all affect coating performance.
Specification And Exposure Mismatch
Even well-applied coatings can fail if the selected system is not suitable for immersion, splash zones, chemical exposure, UV exposure, abrasion, or the expected maintenance interval.
