Cargo units can start to show signs of wear over time, especially when they are being used to transport heavy cargo over long distances. Giving your unit a fresh coat of paint is a quick and effective way to revitalise it and give it a new appearance. Or, perhaps you are using them 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 unit. That said, painting a unit 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 cargo unit.
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 being painted.
What colour should I choose?
You should consider more than just your colour preferences when picking what shade to paint your unit. Different shades can have a dramatic impact on the quality and longevity of your unit 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 unit 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 unit. For instance, a darker shade will absorb heat and increase the temperature inside your unit, especially during the hotter months. Whereas, lighter shades will reflect light and help keep your unit cooler.
How do I prepare my container for painting?
You need to prepare the metal surface of your unit 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 unit 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 unit. Alternatively, you can use a paint and primer in one. The construction should receive several layers of paint to ensure that the exterior is protected from damage, i.e., during extreme weather.
