If your mailbox is rusty but otherwise intact, save money by restoring rather than replacing it. After it receives some rust treatment and a fresh coat of paint, the mailbox will look like new. This is a simple and inexpensive way to enhance the appearance of your home exterior.
You will need:
Step 1: Use the wire brush to remove loose rust and debris from the mailbox. Clean the mailbox with a sponge dipped in soapy water. Alternatively, you can use a cleaner suitable for metal surfaces. Let the mailbox dry.
Step 2: Remove the mailbox flag by unscrewing the screw that attaches it to the mailbox.
Step 3: Apply the rust reformer, which converts rust into a primed and paintable surface. Use a steady, back and forth motion when painting and overlap each stroke slightly. One coat should be sufficient. Allow 24 hours for the rust reformer to dry.
Step 4: Repaint the mailbox with the spray paint. Use spray paint that can be applied to metal and stops rust. You can find spray paint that has a semi-gloss or glossy finish and protective enamel that prevents new rust from forming. Apply at least two light coats of paint a few minutes apart. It will take two to four hours for the mailbox to dry and 24 hours for the paint to set completely.
Step 5: Once the paint has dried, you can affix new house numbers to the mailbox, if desired.
Step 6: If the mailbox flag needs treatment, follow Steps 1, 3, and 4 to remove rust, prepare the surface, and repaint it. Once the paint has dried, reattach the flag to the mailbox with the screw and screwdriver.
