Painting Galvanized Metal: Dos and Don'ts Painting Galvanized Metal: Dos and Don'ts
There are several things to be aware of if you are planning on painting galvanized metal. Metal is galvanized, or coated with zinc, in order to make it better able to withstand the elements. Unfortunately, the galvanization process also makes the metal harder to paint because paint does not like to stick to galvanized surfaces. Below you will find a number of helpful tips for what to do and what not to do when painting galvanized metal surfaces.
Good Galvanized Metal Painting Practices
One thing you will always want to do before even thinking about painting a galvanized metal surface is to sand the surface down thoroughly with sandpaper before beginning. Then, apply at least one and preferably two layers of primer that is specifically designed for galvanized surfaces, sanding in between layers, before applying paint. All of these steps are necessary to create a surface that will bond to your paint.
Bad Galvanized Metal Painting Practices
The first and most important thing to remember when painting galvanized metal is to never attempt to apply paint directly to the metal itself. This will almost always result in paint chipping or peeling off almost immediately. You will also not want to rush the job, as painting galvanized metal is a job that must be done in deliberate steps in order to work.
