Painting Wrought Iron
The process for iron work—such as railings, columns, or decorative hangings—is similar to wood, which means the most important step is preparation. Using a drill with a wire wheel attachment is perfect for removing any rust or deteriorating paint. There are also chemical strippers available for iron, but in most cases, the wire wheel is sufficient.
To prime the metal surface, you need to choose a primer made for metals. You can purchase it in liquid form and apply it with a brush like normal paint; but if the metal has intricate details, you’d be better off using an aerosol spray primer. The metal primer will typically have a rust inhibitor formulated in it and will be either a gray or burnt umber color when applied. Once the primer dries, it provides a surface that new paint will bind to so it will last for years without flaking.
