One of the benefits of purchasing a container vs. renting offsite storage is the ability to customize the box. The shipping container can be a sustainable and much less expensive onsite billboard for your business or company. The best paint for a shipping container really depends on its intended use and environmental exposure.

1. Marine-Grade or Industrial Epoxy Paint

Best for Longevity

• Pros: Highly durable, corrosion-resistant, withstands extreme weather, and protects against rust.
• Cons: More expensive and requires proper surface preparation (sandblasting or power washing).
• Best For: Containers exposed to harsh climates, marine environments, or long-term outdoor use.

2. Direct-to-Metal (DTM) Acrylic or Alkyd Paint

Best for Ease of Use

• Pros: Adheres well to metal, resists rust, and is easy to apply with a sprayer, roller, or brush.
• Cons: Not as tough as epoxy; may need touch-ups over time.
• Best For: Containers used for storage, offices, or housing projects in moderate climates.

3. Oil-Based or Urethane Paint

Best for UV and Abrasion Resistance

• Pros: Strong resistance to fading, chipping, and weather damage.
• Cans: Can be more expensive and harder to clean up.
• Best For: High-traffic areas or containers with heavy use.

Preparation Tips for Painting a Shipping Container

• Clean the Surface: Use a pressure washer and a degreaser to remove dirt and rust.
• Remove Rust: Use a wire brush, sander, or rust converter.
• Prime the Surface: Use a rust-inhibiting metal primer (especially for epoxy or oil-based paints).
• Choose the Right Application Method: Spray painting provides the best coverage, but rollers or brushes can work for smaller areas.

Our recommendation is to consult a painting expert who will be able to properly address the surface before the expense of painting. Once complete containers can add years of affordable and smart exposure and advertising while also serving as a wind and watertight onsite storage.
