6.3 Recommended repair

6.3.1 Table 3 describes the recommended medium and long-term repair to restore “GOOD” coating conditions.

6.3.2 Coating repair should be inspected by qualified inspectors certified to NACE Coating Inspector Level 2, FROSIO Inspector Level III or equivalent as verified by the Administration.

Repair of affected area

•	=	POOR to GOOD
•	=	FAIR to GOOD

•	=	Removal of mud, oil, grease, etc.
•	=	Fresh water hosing
•	=	Drying
•	=	St 3 or Sa 2½^footnote for FAIR condition
•	=	Sa 2½^footnote for POOR condition
•	=	Intact coating next to damaged area should be feathered
•	=	Total soluble salts, calculated as sodium chloride, according to manufacturer's recommendation, but not more than 80 mg/m²
•	=	Climatic control

Medium term (10-year target life) (Not recommended for ships of less than five years of age)

•	=	Coating system approved according to resolution MSC.215(82)
•	=	The same coating system as was originally employed, or a coating system compatible with the original system, or equivalent according to manufacturer's recommendation

•	=	250 µm DFT^footnote
•	=	Minimum two spray coats with two stripe coats

Long term (More than 10 years' target life)

•	=	Coating system approved according to resolution MSC.215(82)
•	=	The same coating system as was originally employed, or a coating system compatible with the original system, or equivalent according to manufacturer's recommendation

•	=	320 µm DFT
•	=	Minimum two spray coats with two stripe coats
