- Zinc salts form on the surface of the zinc-rich primer; avoid prolonged outdoor exposure before overcoating.
- In a clean outdoor environment, the maximum overcoating interval can extend to 3 months, but in industrial or marine atmospheres, shorten the maximum interval as much as possible based on actual conditions.
Before overcoating, if there are visible contaminants, remove them by high-pressure water, sweep blasting or power tool cleaning. 248 Curing time table for a 100 µm (4.0 mils) dry film
