If proper surface preparation and application procedures are not adhered to, coating system failure can occur within 3-6 months Risk for curing. If overcoat window timeframes are not adhered to, coating system failure is possible within the first 6-9 months of application If the PPI checkpoint criteria are met, the following table provides service life expectancy for the listed systems: Coating System Life Expectancy: Surface Preparation Area Method Anti-Corrosion/Anti-Fouling Coating Systems Life Expectancy Underwater Hull (keel to bottom of boot top) Cleanliness Level of SSPC-SP-12 (WJ-2M) MIL-PRF-24647, Type II, Class 1, Grade A, Application 3 <12 years 2.
