Paint pealing/flaking from galvanized substrate. (Part 2)

What is it?

The complete paint system is flaking and lifting from the substrate. A white powdery layer is present under the primer and on top of the exposed galvanized surface.

Possible Causes

The use of an incorrect alkyd based primer. During the drying phase the alkyd produces small amounts of acid by products, which reacts with the Zinc/ Galvanized layer forming a white powdery salt layer. The powdery layer interferes with the coating adhesion to the substrate.

How Can I Fix This Problem

Remove the old coating system back to galvanized surface. Clean with a suitable abrasive degreaser and rinse thoroughly as described in part 1.
