The interval before over coating shall be 24 hours. All paint, when applied, shall provide a satisfactory film and a smooth and even surface, paint shall be thoroughly stirred, strained, and kept at the uniform consistency during application.Paint shall not be applied when the temperature of the metal or surrounding air is below 90 percent, or when it threatens to rain before the painted coat gets dry. Each coat shall be protected during the initial curing period against the possibility of moisture condensation or contamination with foreign matter. All painting works shall be performed by airless spraying, when the coating material is applied by spraying, suitable means shall be provided to prevent segregation during the coating operation. Free oil and moisture shall be removed from the air spray lines of all spraying equipment. Each coat shall be uniform and free from runs, sags and other imperfection. The time between successive coats shall be not less than the minimum not more than maximum re-coating time specified by the paint manufacturer.
