Shipping containers have extensive maintenance and upgrade paths - from installing additional windows to reinforcing. In this guide, we will focus on painting, which is so much more than just a cosmetic touch - it is a crucial step in protecting the structure from the elements. The right tools, techniques, and, of course, it can help you extend your unit’s durability, turning it into a long-lasting, functional, and visually appealing asset.
At Midstate, we will guide you through everything you need to know about painting a shipping container, from the preparation steps to the final touches.
Cosmetic Reasons for Shipping Container Painting
Shipping container painting serves various purposes - from protection to aesthetics. Old units tend to have chipped, scratched, or otherwise damaged paint, making them look cheaper and less visually appealing. Updating the storage unit’s color is a great way to bring back its relevance and make it more fit for commercial use, storage, or as a living space. In addition to that, having unicolor storage units is a great way to build your brand’s identity, making it stand out more and be more discernible. If you are looking for more customization, you can even hire a professional and go for painting a shipping container mural, making your units more unique and recognizable.
Painting can also serve a more practical purpose - it can improve your units’ visibility and safety if painted brightly. In addition to that, companies with a large amount of units can use specific colors to designate their functions - storage, transportation, living space, etc.
Picking Your Paint For Shipping Container
If you are looking for the best paint for shipping containers, make sure it is durable, weatherproof, and waterproof to protect the unit from rust and environmental damage. Here are the most common types of paint for shipping containers:
- Marine-grade paint for shipping containers: These are designed to withstand harsh marine environments and guarantee excellent rust resistance and protection against moisture.
- Acrylic paints: More cost-effective and easy to apply, although they may require multiple coats for full coverage.
- Epoxy-based paints: Some of the most durable and long-lasting epoxy-based options are ideal for areas with extreme conditions like high or low temperatures, heavy rain or snow, high moisture, etc.
While choosing the paint, make sure it can handle the weather conditions your unit is in. If you would like to learn more about custom pain modifications, check our paint modifications.
Essential Tools and Equipment for Paint
Before starting your painting a storage container project, gather the right tools and equipment:
- High-quality primer
- Paint rollers or sprayer
- Sandpaper or a sander
- Wire brushes
- Cleaning solution for surface preparation
- Protective gear (gloves, masks)
Having these tools ensures a smooth application process and a professional finish. Additionally, selecting proper safety gear is essential when dealing with large surfaces or working with industrial-strength paints.
Preparing Your Shipping Container for Paint
Once you have secured all the tools and equipment for the job, make sure to prepare the unit. Without proper prep, the paint won't adhere effectively, leading to poor results.
Check for Lead
Many older storage units tend to have paint with lead, which is highly toxic. Use a lead test kit and, if necessary, consult a professional to remove it safely.
Wash the Container
Different kinds of dirt and grime can prevent the paint from adhering properly. Use a pressure washer and a mild detergent to clean the unit’s surface completely.
Sandblast the Container
If your container has fallen victim to extensive corrosion, sandblasting can help provide a clean, smooth surface. However, it is often costly and can strip away the original rust-resistant coatings, so manual sanding may be a simpler option.
Remove the Stickers
Older stickers and decals can affect the uniformity of the paint layers. Use a scraper or adhesive dissolvent to remove unwanted elements from the surface.
Primer Application
Applying the primer is the best way to ensure the paint adheres well. Choose a high-quality primer for metal surfaces to provide a base for the paint.
