Do You Need Special Spray Paint for Metal?

When it comes to painting metal surfaces, resistant enamel is generally the best option. Its oil base makes it dry a bit slower, but it is highly durable and can even be rustproof. Before you start your project, make sure to read the label or ask your dealer if the paint is suitable for your needs. Primer paint is also a great choice for almost any metal surface, including iron and carbon steel.To make the new coat of paint adhere better, you can sand the old paint or primer with steel wool.

As long as you take your time and follow all the recommended procedures, anyone should be able to paint their metal furniture with spray paint. If you are spraying outside, opt for an opaque paint instead of clear or transparent paint, as they are not UV stable. Additionally, many types of paints leave marks where they were sprayed or dried that can be hard to remove. If you want to make things easier, look for spray paint that has a primer included. To get started, sand the surface with fine-grained sandpaper and then apply a layer of metallic spray primer, keeping the can 6 to 8 inches away from the surface as you work.

If you want to use lacquer or other protective finishes after painting with spray paint, make sure to tape all surfaces and wear gloves to avoid chemical burns. You can also use opaque paints such as zinc electroplating for a bright silver color. Water-based acrylic paints may be more forgiving but can be hard to find in aerosol form for outdoor use. The duration of any spray paint project for metals will depend on how often it is used or touched, as this can cause cracks in the sealant over time if not applied correctly. Your choice also depends on where you are going to apply the finished surface and how much time and money you want to invest in painting it before putting it into service.

If you want more accurate results when painting badges or other designs on your metal project, consider using an airbrush instead of a spray can. Even with a quality spray paint sealer, the project can begin to rust over time where it was applied using spray paint. If your furniture has large sections of rust, it's best to use a primer instead.
