Summary for time between pickling and painting Discussion
time between pickling treatment and painting is the key concern in this thread: Nicolas Fouilloud asks whether steel and aluminium should wait after pickling/paint stripping before phosphating and painting. The answer says the best practice is to move on with no delay at all. Depending on the paint system and application method, the parts may need to be dry first, but the responder notes that in some processes, such as electropainting, drying between pretreatment and painting is not even required. The practical takeaway is that the surface should not be left sitting after pretreatment any longer than necessary, because immediate coating is preferred when the process allows it.
Q. Hello everyone,
I would like to know if there is a time to wait between the pickling treatment of a surface where we strip off paint and the application of surface treament (e.g. phosphating) and then a paint.
Does someone has information for me on this subject ?
I might add that we talking here steel and aluminium.
Regards,
Nicolas

A. Hi Nicholas.
No delay at all is best. Depending on the type of paint and the application method, it may be necessary for the parts to be dry; but In some cases, like electropainting, it isn’t even necessary to dry the parts between pretreatment and painting.
