Case Study: Shipping Container Transformation: A Cooler, More Durable Storage Solution

Cooling Down a Storage Solution: How CertaPro Painters® Transformed a Shipping Container
When converting a shipping container into a storage facility, one unexpected challenge emerged—extreme interior heat buildup.
Originally painted dark blue, the container absorbed sunlight, regularly pushing interior temperatures above 100 degrees.
To combat this issue, CertaPro Painters® of Atlanta/Decatur applied a heat-reflective light-colored coating, drastically reducing interior temperatures.
The project also involved extensive rust removal and surface preparation to ensure a durable finish.
The end result was a cleaner, cooler, and more resilient storage structure, ready to withstand Atlanta’s intense weather conditions.


Project Overview
- Location: Atlanta, GA
- Date: 2024
- Duration: 3 days
- Scope: Full exterior repaint to improve aesthetics and reduce interior heat buildup
Project Details
CertaPro Painters® of Atlanta/Decatur tackled the challenge of transforming a dark blue shipping container into a more functional storage space. By applying a lighter, reflective coating, they significantly lowered the internal temperature—on many days, making the inside cooler than the outdoor air.
Key steps included:
- Surface Prep: Pressure washing, scraping, and sanding to remove rust and stains.
- Paint Selection: Sherwin-Williams Pro Industrial Multisurface Acrylic, chosen for its superior adhesion to metal and stain-blocking properties.
- Application Methods: A combination of hand painting, brush and roller techniques, paint sprayers, and back rolling ensured even coverage and a lasting finish.
Challenges & Solutions
- Extreme Heat Build-Up: The original dark blue paint absorbed too much heat; a light-colored coating reflected sunlight, significantly reducing interior temperatures.
- Rust & Staining: Thorough surface prep ensured proper adhesion and a smooth final appearance.
- Harsh Weather Conditions: The selected paint provides long-lasting protection against UV rays, humidity, and seasonal elements.
Results
The newly painted storage container is now rust-free, weather-resistant, and significantly cooler inside. This transformation improved both the functionality and longevity of the structure, making it a practical and durable storage solution.
Very polite, efficient, detailed and flexible. Will definitely call them again.
