I will tell you how to paint your old mailboxes and review the seven best spray paint for mailbox. So, read till the end!

Before we jump to the process, it is better to have complete knowledge about the paint we need to use as it will be the star of the show.

What kind of paint to use on a mailbox?

The best paint for your mailbox depends on the mailbox’s material. The mailbox can be of aluminum, iron, or wood. So, you need to choose the paint according to that and of course your personal preference.

  • Primer

It’s an important step that you should not skip when painting your mailbox. Primer helps the paint to sit nicely on the surface and works as an extra covering/ protection. It is required in both wood and iron surfaces.

Primers are available in both water and oil formulas. Oil-based primers are more efficient as they go well with all paints. Rust-Oleum’s Aluminum Professional white primer is one of the best in the market and easy to use.

However, I will review the best 2-in-1 spray paints here that do not need extra primer.

  • Water-based paints

If you are not happy with your plain mailbox and plan to decorate it artistically, showing your drawing skills, you can use latex or acrylic paints.

This type of paint works finely on wood or galvanized metals. Acrylic paints are durable in all weathers, so use latex paint with an all-acrylic binder.

  • Oil-based paints

Oil-based paints work best on wood surfaces and provide better coverage, especially on stained surfaces. Though oil paints take longer to dry, they are more durable also prevent rust. Do not use oil paints over water-based primers, as it can result in peeling and chipping.

  • Spray paints

No matter what, it is the most convenient way to paint a mailbox. The two most popular spray paint manufacturers are Krylon and Rust-Oleum. There are many types of spray paints with different features and benefits.

The first thing to consider before buying spray paint is the price. There is no significant difference in quality between low and high-priced spray paints. The more expensive ones give better coverage, but that can be dealt with multiple strokes.

7 best spray paint for mailbox

These are my seven favorite spray paints from Krylon and Rust-Oleum that are perfect for giving the mailbox your desired look.

1. Krylon Fushion All-in-One Spray Paint

The can says 5 times more adhesion, and I vouch for that. Krylon is America’s first spray coating company, and they haven’t let Americans down since 1947.

You can find this spray paint in seven styles: matte, glossy, metallic, satin, hammered, textured, and flat. For the mailbox, you can choose between matte, gloss, or metallic.

The matte finish looks cool but can’t cover dents and all the imperfections. The glossy finish does this work for you and is also easy to clean and maintain.

Another great advantage of this spray paint is that it works on wood, metal, plastic, all surfaces. So, you don’t have to buy different spray paints if your pole is of timber and the letterbox of metal. It’s also a primer+paint, no wonder the 5x adhesion!

Now that we know what the best spray paint for a mailbox is, let’s get to how to paint decorative mailboxes now.

How to paint a mailbox using spray paint?

There are many creative ideas on how to custom paint a mailbox and make it look better. I am sharing here the design I used. You can make your version by using different colors and ideas.

If you just want to paint your full mailbox with one color and don’t want anything extra, you can paint the mailbox where it is and spread some newspaper around the base to not drip paint over the lawn or ground.

But if you plan to put in more effort, then it is better to take out the mailbox and paint the letterbox and pole separately. I unscrewed the mailbox to paint it separately.

The weather has a significant role in the result of the spray paint. The cans of the primers and spray paints say that the ideal temperature of using them is between 50 to 80 Fahrenheit.

So, make sure it’s not too hot while painting the mailbox. Also, ensure the humidity is not more than 85% before painting.

Use a room with good ventilation to paint. Cover your worktable and surrounding area with a cloth or paper to prevent spraying over your surroundings. If you have the house number attached to the pole, take them off before starting.

  • Step 1:

The first step is to clean the mailbox and post before working on them thoroughly. If it’s old and dirty, wash it with a soapy cloth and water.

Let it dry before sanding the surface. Use a medium grit sanding sponge to sand the surface of the mailbox. Sand off any scratches or flakes from the mailbox using the sponge. Keep sanding till the mailbox isn’t shiny anymore.

Don’t forget to sand the flag and numbers. Do a final wipe with a dry cloth to eliminate all the debris. Repeat the same procedure for the pole.

  • Step 2:

If you are not using 2-in-1 spray paint, you need to prime the box properly before spraying the paint. I have already discussed amount primer and its importance in this article. So, don’t forget to prime the mailbox, post, and numbers before painting.

  • Step 3:

If you have used primer, let it dry completely before spraying the paint. You can use any of the best spray paint for mailbox I have reviewed earlier to paint the mailbox and post. I used Rust-Oleum Stops Rust Spray Paint for coloring both my letterbox and post.

I applied 2 coats at a twenty-minute interval. I had unscrewed the red flag earlier and colored it separately. If your flag doesn’t need new painting, you can cover it with painters’ tape while painting the box.

Thoroughly color the pole, too, with the same spray paint. Apply as many coats as possible with a twenty-minute interval for a flawless finish.

  • Step 4:

I used Rust-Oleum Universal Enamel Spray Paint to paint my mailbox numbers in the shade Pure Gold. It looks great with Glossy Black.

  • Step 5 (Optional):

For a better-looking outcome, you can use letter stencils. Once the mailbox is completely dry, place the desired letter stencils at an equal distance from each other and fill in the letters using a gold metallic pen.

I used the American Accents Metallic Leafing Pen. Let it dry completely for one or two hours before recoating if needed. I used a gold pen to match the letters. You can use a different color if you want.

  • Step 6:

Attach the colored house number on the pole and screw the mailbox. The end look is satisfactory aand super stylish.

And that’s it! Your brand-new mailbox is ready. However, if you are looking for something different and creative, then you can do it too.

For instance, you can draw on the mailbox using acrylic paints and brush after spray painting the whole mailbox one color. You can get very creative with mailbox paint ideas and make your colorful mailbox.

If you don’t have house numbers with your mailbox, you can make vinyl numbers using Cricut or Silhouette Cameo and stick them. You can easily make numbers and letters of any color and use them in your mailbox.

Tips for Using Spray Paint:

  • Shake the cans well, at least for a minute before spraying. You should be able to hear the mixing balls rattle while shaking the cans.
  • Shake the bottles after each stroke or at least often during using
  • Overlap each stroke while coating the surface for an even finish
  • Do not hold the spray paint too close or far from the surface. It’s best to spray the paint from a 10–16-inch distance.
  • Apply at least 2 coats and more if needed for the best result and take at least 20 minutes to break between each coat
  • If you think the paint isn’t coming out of the nozzle perfectly or the valve clogs, take off the tip and clean with mineral spirits. Attach it again, and it should work fine now.
