RECOMMENDED USE
NuCharge It Low VOC Epoxy Primer works great over aged galvanized surfaces. If painting new galvanized metal, it is important to know if the galvanizer performed the passive quenching of the galvanizing, which is normal. The quenching will interfere with adhesion of paint, so if it is known that the metal is to be painted, notify the galvanizer and ask that the quenching NOT be done. Removal will be required by either aging for several months or a uniform sweep blast. A professional blaster should perform the operation to blast so that care is taken NOT to remove the protective zinc finish. Once removal is done and cleaning the substrate is complete, priming with NuCharge It Low VOC Epoxy Primer is ideal.
