Shipping containers can start to show signs of wear over time, especially when they are being used to transport heavy cargo over long distances. Giving your shipping container a fresh coat of paint is a quick and effective way to revitalise your container and give it a new appearance. Or, perhaps you are using a container in a conversion project and want to paint it to match your colour theme. Whatever your reasons, painting it is a fantastic way to enhance and personalise your container. That said, painting a container is not always straightforward and you need to ensure that you achieve a quality outcome. With that in mind, we’ve put together a useful guide on everything you need to know about painting a shipping container.
What paint is recommended for shipping containers?
Marine-grade paint should always be used for shipping containers. This paint is exceptionally durable and provides quality protection from the elements. Typically, an acrylic marine-grade paint is used with a satin finish. A gloss finish should be avoided as it is more prone to damage and also makes blemishes more obvious. At the same time, the nature of matte paint means that it attracts dust and shows dirt more clearly. This is why a satin finish is the preferred option when painting shipping containers.
What colour should I choose?
You should consider more than just your colour preferences when picking what shade to paint your shipping container. Different shades can have a dramatic impact on the quality and longevity of your shipping container. Keep in mind that lighter and darker shades will require more intensive upkeep to keep them looking in a good condition. For that reason, many individuals and businesses choose to paint their containers in neutral shades that require less cleaning and fewer touch-ups. You should also be aware that the shade you choose can affect the temperature of the interior of your container. For instance, a darker shade will absorb heat and increase the temperature inside your container, especially during the hotter months. Whereas, lighter shades will reflect light and help keep your container cooler.
How do I prepare my container for painting?
You need to prepare the metal surface of your shipping container before you can paint it. In most cases, shot blasting is used to remove any contaminants such as dirt, rust and so on. Then, a primer must be applied to the areas of the container being painted. This will help to ensure a smooth finish and extend the lifespan of the paint. Once the primer has dried fully, you can start painting the shipping container. Alternatively, you can use a paint and primer in one. The container should receive several layers of paint to ensure that the exterior of the container is protected from damage, i.e., during extreme weather.
