Best paint for sheet metal.

You first are advised to prepare the surface of the item to be painted so that the paint for galvanized metal stands its best chance of looking good for several years. The red oxide zinc chromate is best used for steel ironworks and galvanized steel. Getting a rusty metal object ready for painting takes a bit of work but it s totally doable.

You can use either a water based acrylic paint or an oil based paint as long as the container identifies for metal somewhere on its labeling. Spray in a quick smooth and even pattern until the surface is covered. Elbow grease will do the trick for lightly rusted metal but tougher jobs may require a power sander or chemicals. Apply spray paint to the sheet metal.

Oil based paints take much longer to dry and they need a high quality paintbrush that doesn t shed during application. There are generally two types of metal paint primers that you can use on your shed red oxide zinc chromate and zinc chromate. Bituminous latex acrylic and vinyl paints tend to adhere well to galvanized metals. Paint can t bond to rust so you ll need to start by restoring the surface.

Use the zinc chromate if your shed is made from aluminum or any light alloy. Once the metal has been cleaned and is dry prime it using an exterior multipurpose latex primer or a latex primer that is made specifically for galvanized metal.
