Custom Shipping Container Paint Options
Dry Box offers three levels of shipping container paint service: Economy (fast color change), Standard (rust treatment plus a full DTM coat), and Custom (complete prep, decal removal, and any color). Custom container painting starts from $1,950 to $2,850 based on container size and how in depth the paint job is. Color match painting and discounted white primer for interiors are also available.
A shipping container can outlast almost anything on your property, but its factory paint will not. Years in the sun, salt air, and Northwest rain can slowly turn a crisp steel box into a faded, rust-streaked eyesore. The right shipping container paint protects your investment for decades and makes it look like it belongs there.
Why Custom Painting a Shipping Container Is Worth It
Fresh paint is not just cosmetic on a steel box. A quality coating seals out moisture, stops rust before it starts, and can add years to the working life of the container. That protection matters most in wet climates where bare or chipped steel corrodes quickly.
Appearance pays off too. A container matched to your property or brand colors blends in at a home, satisfies picky neighbors and HOAs, and looks professional on a commercial site. A well-painted box also holds its resale value better than one covered in rust streaks and faded shipping line logos.
Shipping Container Paint Options at Dry Box
Dry Box built three price points for shipping container exterior paint so you only pay for the level of finish your project needs.
Economy Paint
The Economy option is a straightforward color change. Only aggressive rust gets prepped and primed before a quick coat of paint is sprayed on. It is the fastest way to make an older box presentable on a budget.
Standard Paint
The Standard paint job goes deeper. Rust areas are treated and primed, door gaskets are taped off, the peeling edges of shipping line decals are sanded, and larger dents that affect appearance are pounded out. The container is then sprayed with durable DTM paint.
DryBox uses RAL 1015 Light Beige as the stock color.
Custom Paint
The Custom paint order is quoted to your exact project requirements. It normally includes treating all rust, removing all door hardware, blending or removing shipping line decals, then priming and painting with DTM product.
Custom container painting at Dry Box starts from $1,950 to $2,850 depending on container size and how in depth the paint job is.
The stock color is RAL 1015 Light Beige, purchased in bulk so the savings pass to you. Custom colors are available for an additional charge, and special colors like reds, neons, and emeralds take considerably more paint, so extra charges apply.
Color Match Painting
Want your container to disappear into the property instead of standing out? Color match painting matches your container to an existing building, home, barn, or outbuilding, or to any preferred color code you provide.
It's a popular choice for painted shipping containers placed at residences and businesses with strict appearance standards.
Camo Painted Containers
For container hunting cabins, and rural land, camo paint is available as an upgrade, and Dry Box stocks new 20ft shipping containers with camo paint ready to deliver.
A camo painted container tucks into the treeline and draws far less attention than a bright steel box in the woods.
Interior Paint
The inside matters too. If Dry Box is already painting your exterior, you can add shipping container interior paint in white primer at an attractive discount before the paint gun is cleaned.
Fresh white primer cleans and brightens the interior without the off-gassing and odor of standard paint, and full interior painting is available by request and specification.
How to Paint a Shipping Container
Painting a shipping container is not like painting a fence. Corten steel holds heat, sheds water, and punishes shortcuts, so the prep work decides how long the finish survives. Here is the process professionals follow.
Start by washing the entire container to remove salt, grime, and chalky oxidized paint. Next, grind or wire-brush every rust spot down to sound metal, then treat those areas with a rust converter or spot primer. Skipping this step is why so many DIY paint jobs bubble within a year.
Pound out larger dents that will show through the finish and tape off door gaskets, locks, and data plates. Apply a rust-inhibiting primer to bare metal, then spray two coats of DTM exterior metal paint, keeping a wet edge along the corrugations. Let the container cure fully before loading anything against the walls.
Why Let Dry Box Handle It
Painting shipping containers well takes commercial spray equipment, bulk DTM product, and a crew that preps steel every day. Dry Box paints containers in a controlled yard environment, so overspray never lands on your truck and weather never ruins a half-finished coat. Bulk paint purchasing also keeps pricing lower than most one-off contractor bids.
There is a practical bonus too. Your box arrives finished and ready to work, and the same team can handle other container modifications like doors, windows, vents, and lock boxes in the same visit.
What Kind of Paint to Use When Painting a Shipping Container
The best paint for shipping containers is a direct-to-metal (DTM) acrylic or alkyd coating rated for exterior steel. DTM products bond to properly prepped metal without a separate topcoat system, resist UV fading, and flex with the steel as it expands in the sun. This is the same category of paint for shipping container work that Dry Box sprays in its yards.
Standard house paint is the wrong tool for the job. It is formulated for wood and masonry, so it peels off smooth steel and offers little rust protection. Any exterior metal paint you choose should be paired with a rust-inhibiting primer on bare or repaired spots.
If you plan to paint the interior of a storage container yourself, ventilation matters as much as the product. Solvent-based coatings release volatile organic compounds while they dry, and the EPA reports that VOC levels can run far higher inside enclosed spaces than outdoors. A steel box with the doors shut is about as enclosed as it gets, which is another reason the primer-white interior service is a smart add-on.
Shipping Container Painting Ideas
Container paint does more than fight rust. Businesses turn shipping containers into rolling billboards with brand colors, while homeowners match their box to the house so the HOA never sends a letter. Farms and ranches often pick deep greens and browns that blend into the treeline.
A fresh coat also transforms workspaces. A shipping container office painted in company colors looks intentional on a job site instead of temporary. Even storage containers for rent benefit, since many customers request neutral tones for placements in visible locations.
Your starting canvas matters as well. One trip shipping containers arrive nearly new and need minimal prep for a flawless finish, while cargo worthy shipping containers cost less up front and become great candidates for a Standard or Custom repaint.
Frequently Asked Questions
How long does shipping container paint last?
A professionally applied DTM finish over properly prepped steel typically lasts 10 years or more outdoors. Coastal salt air and constant sun exposure can shorten that window, so expect touch-ups sooner in harsh climates.
How much paint does it take to cover a 40ft container?
Plan on roughly 15 to 20 gallons for two full exterior coats on a 40ft box, since corrugated walls add about 10 percent more surface area than flat panels. Bright reds and neons often require extra coats to reach full coverage.
Can a shipping container be painted in cold or wet weather?
Most DTM coatings need surface temperatures above 50 degrees Fahrenheit and dry conditions to cure correctly. Painting in rain, heavy dew, or cold snaps traps moisture under the film and leads to early failure.
Does painting a container affect its CSC certification for shipping?
Paint itself does not void a CSC plate, but covering or removing required markings and the data plate can cause problems at ports. If your box will ever ship cargo again, keep the plate and markings visible.
Will a dark paint color make the container hotter inside?
Yes, dark colors absorb more solar heat and can raise interior temperatures noticeably in summer. Lighter shades like the RAL 1015 Light Beige stock color reflect sunlight and keep contents cooler.
