How to Age Galvanized Metal

Galvanizing is a chemical process that is used to coat iron and steel and that is usually accomplished with the use of zinc. The purpose of galvanizing is to minimize corrosion; zinc prevents oxidation of the metal and protects it by forming a barrier. However, many people would like to distress or age galvanized steel to make it blend with other furniture. When steel is aged, it presents a more rugged or antique look that helps create an old-world charm and that is aesthetically appealing when compared to the shiny look of galvanized steel.

Instructions

1. • 1

     Sand the galvanized steel with the sandpaper to remove the outer zinc protective layer. This will allow the muriatic acid to react with the steel surface.

   • 2

     Apply the muriatic acid to the galvanized steel, ensuring that the entire surface is well covered.

   • 3

     Remove the muriatic acid using water, and dispose of the acid carefully.

   • 4

     Inspect the metal surface; if more aging is required, repeat the sanding and apply muriatic acid again.
