What You'll Learn

Choosing the right paint
Type of Paint
Select a paint specifically designed for plastic surfaces. These paints are formulated to adhere well to plastic and provide a durable finish. Well-known brands like Krylon and Rustoleum offer spray paints specifically made for plastic, ensuring a smooth and even coat.
Primer
Using a good-quality primer is crucial when painting plastic. A plastic primer will provide a base layer that promotes better paint adhesion and helps the new colour stand out. Allow the primer to dry completely before applying the paint.
Paint Finish
Consider the desired finish for your mailbox. Do you want a metallic look, such as copper? Or do you prefer a matte or satin finish? Choosing the right paint finish will enhance the overall appearance of your mailbox.
Durability
As your mailbox will be outdoors, exposed to varying weather conditions, choose a paint that is durable and weather-resistant. Look for paints that are specifically designed for outdoor use, as they will be more resistant to fading, chipping, and other forms of wear and tear.
Light Layers
When painting plastic, it is generally recommended to apply light layers of paint, allowing each coat to dry completely before applying the next. This technique helps achieve a smooth and even finish. It also prevents the paint from dripping or becoming too thick, which could affect the overall appearance and durability.
By considering these factors and choosing the right paint, you can transform your plastic mailbox and give it a fresh new look that will last for years to come.

Preparing the mailbox
Firstly, ensure the mailbox is clean and free of any dirt or debris. Use a mild soap and water solution to wipe down the mailbox, paying particular attention to any areas with built-up grime. If there are any stickers or glue residue on the mailbox, carefully remove them. A plastic scraper can be useful for this step, but be gentle to avoid scratching the surface.
Once the mailbox is clean and dry, lightly sand the surface with fine-grit sandpaper. This step is important, especially if your mailbox has a smooth finish. Sanding creates a rougher surface for the paint to adhere to, resulting in better paint adhesion and a longer-lasting finish. Be sure to sand any additional hardware that you plan to paint as well.
Next, apply a primer to the mailbox. A primer will help the new paint colour stand out and ensure its longevity. You can use a brush, roller, or spray primer for this step, depending on your preference. Be sure to follow the instructions on the primer for the best results, and allow adequate time for the primer to dry completely before moving on to the next step. In some cases, you may need to apply two coats of primer, especially if you are painting over a darker colour or if the original material is particularly shiny.
After priming, you can now prepare the paint. Choose a paint that is specifically designed for plastic surfaces. There are several options available, including spray paints and hand-painting with a brush or roller. Well-known brands such as Krylon and Rustoleum offer a range of colours and finishes specifically formulated for plastic adhesion. If you plan to use a metallic paint, be sure to check if it is suitable for outdoor use, as some metallic paints are intended for indoor use only.
Finally, before you begin painting, consider using painter's tape to cover any areas you want to protect, such as the red flag on the mailbox. This will ensure that only the desired areas are painted, giving your mailbox a neat and professional finish.

After the primer is dry, you can move on to the painting step. Choose a paint that is meant for plastic and consider the purpose of the mailbox, whether it will be kept indoors or outdoors.

Painting the mailbox
Painting a plastic mailbox is a great way to refresh its look or make it stand out. The process is relatively simple, but it requires some preparation and patience. Here is a step-by-step guide to help you achieve a professional-looking finish:
Cleaning and Preparation:
Firstly, ensure you remove any old glue, stickers, or numbers from the mailbox. You can use a blow torch to remove stubborn residue, but be cautious and only use this method if suitable for your type of plastic. Once the mailbox is free of residue, give it a good clean. If your mailbox has bird droppings or tough stains, you may need to use sandpaper to clean it thoroughly. After cleaning, let the mailbox dry completely.
Priming:
Use a brush, roller, or spray primer to cover the mailbox with a suitable primer. This step will help the new paint adhere better and create a smooth base for the paint. It is essential, especially if your mailbox is made of a smooth material. Apply two coats of primer if needed, allowing each coat to dry completely before applying the next.
Painting:
Choose a spray paint specifically designed for use on plastic. Well-known brands like Krylon and Rustoleum offer spray paints formulated for plastic, ensuring the paint adheres well and lasts longer. When painting, use light layers, allowing each coat to dry completely before applying the next. This technique will ensure a smooth and even finish.
Sealant (Optional):
If desired, you can apply a clear sealer to protect the paint and prevent chipping. Spray several coats of the sealer, allowing each coat to dry in between applications.
Finishing Touches:
Once the paint and sealer (if used) are completely dry, you can add the finishing touches. If you wish to add house numbers, you can use stick-on reflective numbers or stencil the numbers using paint.
By following these steps, you can transform your plastic mailbox and give it a brand-new look that reflects your style and personality.

Sealing the paint
Start by allowing the paint to dry completely. It is important to be patient during this step, as rushing it may affect the final outcome. Once the paint is dry, you can move on to the next step.
The next step is to apply a sealer to protect the paint job. There are a few options available for this. You can use a spray acrylic sealer, which will help protect the paint and give it a nice finish. Allow the spray acrylic to dry completely before moving on to the next step.
After the spray acrylic has dried, you can apply a coat of polyurethane. Polyurethane is a durable finish that will provide an additional layer of protection against the outdoor elements. Make sure to follow the instructions on the product and apply it in a well-ventilated area.
If you prefer a natural finish, you can opt for a product like Polytrol by Owatrol USA. It is a colour restorer that can be used on plastic and a variety of other surfaces. This product will help restore the colour and shine of your mailbox while also providing some protection.
Additionally, you can use a product like Mod Podge to seal acrylic paint. However, be cautious as it may leave streaks, and it might not give you the smoothest finish. Always test these products on a small area first to ensure you are happy with the results.
