Can You Spray Paint Over Old Painted Metal?
Yes, with a little TLC, someone else’s trash can become your treasure, but only if you do it right. Giving an old piece of metal a full makeover requires a little work, and skipping steps can result in a messy-looking finished product. Follow the steps below before spray painting over rusted old metal:
- 1Inspect the object. First, inspect the object. You want to look for chipping paint, cracks, holes, and rust. If you notice any of the following, you will need to fix those things before repainting the surface.
- 2Fix paint chipping. If the old paint is chipping, you will want to strip the old paint before repainting the item. Use a spray-on chemical paint remover for furniture to remove the old paint first.
- 3Fix any holes or cracks. If the object has any holes or cracks, sand the areas to get to bare metal. Then, use an epoxy made for metal surfaces to fill in the holes. Allow it to dry completely.
- 4Sand the rust spots. Use a stiff wire brush or chip brush to sand off as much rust as possible. It’s ok if you can’t remove all of it.
- 5Even if there are no visible blemishes to the object, sanding the entire surface before repainting is essential. Roughing up your surface allows the new paint to stick better. Then, use a fine-grit sandpaper to lightly sand the entire surface. You can do this by hand or with a power sander.
- 6Finally, use a primer especially made for metal and coat the entire object. Allow the primer to dry completely before coating with new spray paint. Be sure to use spray paint specifically designed for metal surfaces.
