How to Patina a Plastic Mailbox

Step One

Remove the old plastic mailbox from its post and give it a good cleaning with soapy water and a sponge. Rinse it well and let it dry completely.

Step Two

Protect your surface with kraft paper or painter’s drop cloth.

Apply first coat of Metal Effects Primer by Modern Masters. Apply with a sponge applicator in thin, light strokes to cover the entire mailbox.

Allow to dry for at least 30 minutes.

Step Three

Apply a second coat of Primer. This time allow for a generous layer to fill in any missing areas of the first layer.

Allow to dry for at least 30 more minutes.

Step Four

Using a new sponge brush, apply a first coat of the special oxidizing bronze paint. This is where the ordinary plastic mailbox turns into a more high-end metal-looking mailbox.

Dry mailbox for another 30 minutes.

Step Five

For the final coat of bronze paint, apply in small sections at a time.

After applying a few strokes of paint, spritz the blue patina aging solution over the wet paint area.

Get creative and experiment by varying the sprays of the aging solution from a light, airy spray at a distance to a closer more concentrated spray that leaves pretty drip marks behind.

This is where the magic happens. The patina aging solution will begin to change the bronze paint into an aged patina!

What is patina?

The patina finish is defined as a “green or brown film formed on copper and bronze by oxidation, typically produced naturally by exposure to the air or chemicals.” In other words, it’s that beautiful weathered look that metal gets over time. Some refer to it as rust.

Is patina the same as rust?

Patina and rust are not the same things. Patina is a thin layer of oxide that forms on the surface of the metal, and it is often considered to be visually appealing.

Rust, on the other hand, is a form of corrosion formed from oxygen and moisture in the air that can cause the metal to weaken and break down over time.

Patina comes with age, but rust can show up in just a few short days or weeks. Rust can be dangerous, but the patina isn’t.

What color is patina?

Patina comes in a large range of colors due to the fact that they are created by nature and each patina color is unique. However, there are a few popular patina colors that are often soft after in the way of patina finishes. These are the blue, bronze color used in this project and the green, copper patina. Both are gorgeous!

“Patina” is a term that refers to the blue-green layer of corrosion that develops on the surface of copper when it is exposed to sulfur and oxide compounds. The word is derived from the Latin term for a shallow dish.

What is the difference between tarnish and patina?

The difference between tarnish and patina is that tarnish is a film that forms on the surface of silver, copper, or brass when they are exposed to the air, while patina is a green or brown film that forms on copper and bronze. Both tarnish and patina are caused by oxidation.

Most of us like the look of a patina and don’t like the tarnish!
