What Does Flooding Method Mean?
The flooding method refers to an approach used to apply a coating to a metal's surface as a means of corrosion protection. The metal is typically submerged into a large volume of a liquid coating and removed once fully coated.
Corrosionpedia Explains Flooding Method
The flooding method involves vertically lowering a piece of metal into a large container filled with paint or pigment fluid. This fluid contains properties intended to prevent corrosion, wear and/or deterioration of the metal due to exposure.
The flooding method may also be the source of a paint application defect characterized by the flowing or dripping of paint vertically along the metal surface due to gravity. This defect forms a wavy tear-like fluid impression on the surface. It occurs due to the difficulty of ensuring a precise amount of fluid application per unit surface area. Spraying or brushing can be used as a remediation for this defect.
Flooding results in a visibly darker or deeper color of the coated area than surrounding areas.
