Have you ever wondered why shipping containers come in an array of colours? Are you undertaking a cargo container modification and want to give your unit a new lease of life? Paint is one of the most important aspects of container maintenance, helping to keep them protected from the elements and extending their lifespan.

In this blog, we thought we would take a closer look at why these containers come in different colours and why painting forms such a vital part of your cargo container modification.

Why do shipping containers come in different containers?

Each year, around 1.85 billion metric tons of cargo are shipped around the world in containers. This is a huge logistical process, and the longer these logistic companies are able to continue using their containers, the more cost-effective the process becomes.

Containers are made from a particular grade of steel alloy, which over time will begin to corrode with exposure to the seawater and sunlight. Painting the exterior of these containers provides a long-lasting barrier that prevents this from happening and boosts their lifespan.

However, painting them is not just about protecting them. With millions of containers in use across the globe, being able to quickly identify which containers belong to which organisation is essential. That is why one of the most common reasons for the differing colours is to ensure that they indicate which leasing company each unit belongs to.

Colours can also impact the products being stored inside. Darker colours will absorb the heat from UV rays, increasing the temperature of the container. On the other hand, white units are able to reflect that heat, keeping the interior cooler.

How to paint a shipping container

Whether it is extending the longevity of your unit or you are looking for cargo container modifications, painting the exterior of your shipping container is essential. When it comes to painting your shipping container, there are certain things to remember:

1. Inspect the exterior

Before you can think about painting your shipping container, you will first need to conduct a thorough examination of the exterior. You should be looking for signs of wear and tear and areas that will need repair, completing all these works before you can consider painting.

2. Remove any decals

When you are confident the exterior is free from damage, then then next step is to remove any stickers and decals. You want to ensure the surface is completely free from these; otherwise, it can cause issues when painting.

3. Sand it down

With the exterior free from decals, the next step is to sand down the entire surface to create a smooth finish that is free from flaky paint or rust. For the best results, you should utilise a sanding machine to clear all debris.

4. Wash it down

After you have finished sanding the exterior, the next stage is to conduct a thorough wash down using a commercial cleaner. This will ensure all residue, dirt and chemicals are thoroughly removed.

5. Commence painting

Once your container is fully dry and the weather is sunny, the only thing left to do is to paint your cargo container. Rather than picking up a paintbrush, you should opt for a professional airless paint sprayer to ensure the very best finish.

What kinds of paint should you use?

When it comes to choosing the right paint for your cargo container modification, there are many things that you should consider. This will depend on the purpose of your shipping container. For example, if it is going to continue to be used in logistics, then you will need to ensure that you are using marine-grade paint.

However, if you are planning on cargo container modification so that you can use the unit for residential or commercial reasons, then there is a wider range of options available to you. Whatever you are planning, your shipping container will still be exposed to the elements, so you will need to ensure that paint you are using is water-resistant and capable of protecting the steel from corrosion.

When it comes to a finish, you should opt for a satin finish. This is because glossy options tend to reveal blemishes, while matte options will tend to showcase dirt and dust more prominently.

What if your container falls victim to graffiti?

Unfortunately, vandals are just as likely to target your shipping container as they are any permanent structure. This can be a very frustrating time, but thankfully removing it can be a simple process. The first thing is to use a high-powered pressure washer to remove the graffiti; this should lift the vast majority of the painting off, leaving your container behind.

However, it might also remove some of the original paint, or you might find residue from the graffiti is left behind. In these instances, you will need to repeat the steps listed above, sanding down the affected area, preparing it and then repainting the exterior.

How to maintain your shipping container?

When it comes to cargo container modification, effective maintenance is crucial in keeping your unit in the very best condition possible. Maintaining the paint on your container begins at the same time that you start adding your first coat.

You want to start painting on a dry and sunny morning, as this will prevent dew from settling on the surface and causing blisters on the paintwork. These blisters can reduce the lifespan of the paintwork, meaning you will need to keep adding new coats. If you are planning on adding primer as part of your cargo container modification, then make sure you use a thick coating and ensure it is fully dry before spraying the paint.

Finally, you also want to ensure that you are keeping a regular eye out for signs of corrosion. The earlier you are able to catch this, the lower the impact it will have and the easier the repairs will be. If you have spotted areas of rust, then mask of the surrounding area with tape and scrub the area thoroughly to remove any corrosion. Once the area is clear, you can then sand it down and repaint it to create the perfect finish.

The Waterproof Myth

One of the most common questions about shipping containers is, “Are they waterproof?” While standard shipping containers are designed to keep cargo dry during transit, modifications and local conditions can influence their ability to remain fully watertight. For Australian industries, where extreme weather is common, ensuring containers are waterproof is critical.

At Modulate Group, we provide customised solutions that not only enhance waterproofing but also improve insulation and durability. Whether for storage, office spaces, or specialised facilities, our container designs are built to withstand Australia’s harsh conditions.

Our shipping container solutions are designed for the harsh Australian weather – Ablution Unit for remote mining site in PNG.

How Standard Shipping Containers Stay Dry

Shipping containers are constructed from durable, weather-resistant corten steel and designed to endure months at sea. Key features include:

1. Seamless Welds: Prevent water ingress at joints and edges.
2. Rubber Door Seals: Create a tight barrier against rain and moisture.
3. Corrugated Steel Panels: Reinforce strength while directing water away from the structure.

While these features are effective during transit, modifications or long-term use can introduce vulnerabilities. This is where Modulate Group’s expertise comes in.

Modulate Group’s Approach to Waterproofing

Pro Tip: If your site experiences heavy rainfall, opt for guttering systems to improve water management.

2. Cork Condensation Barrier Coating

Traditional insulation methods, such as foam, can trap moisture and lead to mould. Instead, we offer Corkon’s cork condensation barrier coating as an optional insulation upgrade for our containerised buildings. This innovative solution enhances thermal regulation while helping to reduce condensation-related issues.

• Natural Breathability: Cork allows moisture to evaporate, reducing the risk of condensation.
• Eco-Friendly: Made from renewable resources, it aligns with sustainability goals.
• Durability: Withstands temperature extremes without degrading.

Pro Tip: Cork is ideal for climates with high humidity or fluctuating temperatures, making it a superior choice for moisture control.

We’ve recently started incorporating Corkon into our offerings, and its easy application and immediate benefits make it a great addition. Learn more about Corkon at www.corkon.com.

3. EPS Insulation Options

For standard insulation, Modulate Group uses 50mm EPS panelling, with the option for thicker insulation depending on your needs. EPS panelling offers:

• Thermal Efficiency: Maintains a stable internal temperature.
• Lightweight Durability: Adds minimal weight while providing robust insulation.
• Customisation: Can be adjusted to meet specific thermal performance requirements..

Pro Tip: Thicker insulation is ideal for containers used in extreme heat or cold conditions.

5. High-Quality Windows and Doors

Water ingress through windows and doors can be a common issue in modified containers. Modulate Group mitigates this by:

• Using high-quality doors and windows with advanced manufacturing techniques.
• Ensuring proper weatherstripping to seal gaps and prevent leaks.
• Installing flashing correctly to direct water away from vulnerable areas.
• Guaranteeing doors are properly aligned and fit snugly within their frames.

Pro Tip: Regular maintenance of weatherstripping and door alignment can further enhance long-term waterproofing.

Common Causes of Leaks and How We Mitigate Them

1. Corrosion

Over time, untreated steel can rust, leading to holes and leaks. Modulate Group uses high-quality materials, and applies industrial-grade paint to prevent corrosion.

2. Improper Modifications

Poorly executed modifications, such as cutting for doors or windows, can compromise waterproofing. Our expert team ensures all alterations are sealed to Australian Standards.

3. Roof Water Pooling

Flat roofs on standard containers can lead to water pooling. By incorporating skillion roofs or Colorbond alternatives, we eliminate this issue.

FAQs About Waterproofing Shipping Containers

40ft Modular Office Space – The Before and after of a fully insulated & waterproofed office space.

Modulate’s Australian-manufactured portable building solutions are robustly engineered for low maintenance, maximising uptime over a 25-year life expectancy. The pictured container, under construction in their Newcastle NSW facility, is 4m. wide.

New generations of more easily and safely portable Australian-made container-based buildings – including stackable and double-width 4.5m-wide types – are being introduced across Australia by the Modulate Group. 

The robust cyclone-rated structures, configured from standard 20ft, 30ft, and 40ft (approx. 6m, 9m, and 12m) container templates, respond to expanding demand for comfortable, functional, and comprehensively fitted out buildings that can be readily moved from site to site as production and construction demands change in fast-moving market sectors. 

“With a design life of 25 years under heavy use with low maintenance, these quality buildings can be engineered to cost-effectively meet the repeat-use needs of sectors such as mining, energy, infrastructure, construction, government projects, defence, and water and power utilities,” says Modulate General Manager, Jack Adams. 

With wider configurations, and a huge range of customisations, Modulate relocatable buildings can be configured as offices, kitchens, bathrooms, catering facilities and more – all with more comfort and more features to suit each application

Australian-manufactured reliability 

Such major operations – often needing to nimbly shift resources to satisfy changing market demands – typically require a range of building types, instead of one-offs. All must be delivered reliably on time to prevent expensive downtime. Rather than providing piecemeal answers involving multiple contractors and potential delays each step of the way, Modulate Group has invested in a major 20,000 sq m, modern production facility in Mayfield, Newcastle, where production and customisation to different needs are handled in-house. The facility is divided into a series of production shed, including zones for assembly, construction, fabrication, painting, and final fit-out, to deliver efficient and high-quality final product. 

Benefits of this “under one roof” approach include scrupulous premium quality control, reliability of delivery, engineering to statutory compliance requirements, and top safety and comfort features adapted to individual site needs, says Jack Adams, whose family has decades of experience in the establishment, relocation rehabilitation of major mine, construction and infrastructure sites. 

Customisations expand options 

Major features of Modulate Group buildings that distinguish them from the offerings of ad hoc operation, include: 

• A larger range of dimensions, including both standard width 2.4m container structures, or variations out to 4.5m wide, accommodate the needs of facilities such as site offices, accommodation, catering facilities, engineering workshops, maintenance facilities, safety and medical facilities, testing facilities, chemical stores, and electrical, switchboard, automation, and process control centres. 
• Wider-than-standard floor plans offering 25-87 per cent more space, depending on length, where more space where this is required to increase light, comfort, functionality and account for the special insulation needs of both plant and of people who must work in widely varying climates ranging from alpine to tropical.  
• Stackability, to save site and yard space where required. A stackable linking kit secures the structures without the need for extensive engineering. 
• Quality doors, windows, insulation, air conditioning, electrical, flooring, and roof features are standard, while structures can be custom-engineered to provide wider access, greater window and service counter openings (such as for service areas) and security. 
• Robust portability. Just like standard shipping containers, Modulate buildings are easy to transport over long distances and can withstand harsh transport conditions that may buckle and twist flimsier structures. Easy to load and unload, Modulate buildings can be tilted off or lifted off using a suitable crane with spreader bar. 
• Twist-lock secure fixing, adapted from standard container lock configurations, anchor buildings in place on trucks during transport, eliminating the need for extensive, expensive and time-consuming ad-hoc securing to guard against damage and accidents during relocation. 
• Design life expectancies of 25 years, structural warranty of 10 years, and general warranty of a year, all backed by a substantial organisation which prides itself on premium quality and engineering.  

“Modulate Group set out with a clean sheet of paper to produce flexible ranges of buildings that speak the language of markets focussed on quality, safety, compliance and cost-efficiency. This approach – many elements of which are patented – has attracted repeat interest from major mining, construction and infrastructure groups that prefer to deal with single-source suppliers who match their own world standards of performance,” says Jack.

Lighting is a crucial element in containerised buildings, whether used for site operations like offices, workshops, and lunchrooms or hospitality applications such as bars, cafes, and commercial kitchens. Choosing the right lighting not only ensures safety and functionality but also enhances the ambience and experience within these compact, versatile spaces. 

This guide will help you select and optimise lighting for both interior and exterior needs, using containerised building examples across site and hospitality spaces. We’ll also provide tips tailored to the Australian market, covering energy-efficient options and practical advice for different modular setups. 

The Importance of Effective Lighting in Containerised Buildings 

Lighting impacts both functionality and atmosphere in containerised buildings. In a lunchroom or workspace, good lighting fosters productivity and comfort. In a hospitality setting, such as a cafe or bar, lighting creates ambience and supports the unique experience you want your guests to have. 

Well-chosen lighting can also help modular buildings meet Australia’s energy efficiency and safety standards, which are critical for long-term sustainability and cost-effectiveness. For an overview of lighting’s impact on productivity and comfort, see Lighting Council Australia’s workplace lighting insights here. 

Interior Lighting Solutions for Containerised Buildings 

The lighting inside containerised buildings should be carefully planned to meet the needs of the space, whether it’s an office, workshop, or commercial kitchen. Here are some key interior lighting types that work well in these settings: 

1. Ambient Lighting 

Ambient lighting provides the main source of illumination, creating a comfortable level of brightness across the entire container. LED lighting options are ideal for ambient lighting in containerised buildings due to their efficiency, durability, and ability to brighten up compact spaces. 

• LED Panels: LED panel lights deliver bright, even lighting, ideal for creating a spacious feeling in confined areas. They work well in spaces like lunchrooms and office areas. 
• Downlights: Recessed LED downlights offer a clean, subtle look that’s versatile for general lighting needs in modular setups. 

Pro Tip 1: Opt for LED lights with a colour temperature between 3000K and 4000K to create a warm, comfortable atmosphere that suits workspaces and social areas alike. 

2. Task Lighting 

Task lighting focuses illumination on specific areas where concentrated light is required, such as workbenches in workshops, kitchen prep areas, or desks in offices. Proper task lighting can improve efficiency and reduce eye strain. 

• Adjustable Desk Lamps: Perfect for office setups, adjustable LED desk lamps provide focused lighting at individual workstations. 
• Under-Cabinet Lights: LED strips or pucks under cabinets in kitchen areas or workspaces provide bright, targeted light that helps reduce shadows on work surfaces. 

Pro Tip 2: Consider adding motion-sensor task lights in areas like switchrooms or lunchrooms where lights may be accidentally left on. Energy Rating Australia highlights energy-saving lighting options here. 

3. Accent Lighting 

Pro Tip 3: Use dimmable accent lights in spaces where ambience is key, such as hospitality areas. Australian Interior Design Association offers insights into lighting that enhances interior design in small spaces here. 

Exterior Lighting Solutions for Containerised Buildings 

Exterior lighting is essential for safety, security, and visibility. From motion-activated security lights for industrial sites to decorative lights for cafes, exterior lighting enhances both functionality and appeal. 

Pro Tip 4: Position security lights around access points and walkways for optimal coverage. Crime Prevention NSW offers additional tips on security lighting placement here. 

Pro Tip 5: Choose waterproof and weather-resistant fixtures for outdoor areas to ensure they withstand Australia’s varying climate. Green Building Council of Australia discusses eco-friendly lighting solutions for outdoor settings here. 

Lighting Controls for Energy Efficiency 

Implementing smart lighting controls in your containerised building can improve energy efficiency and reduce costs, particularly for high-use spaces like workshops, commercial kitchens, or busy cafes. 

• Motion Sensors: Motion sensors are ideal for ablution units, changing rooms, or back-of-house areas where lights may otherwise be left on. 
• Smart Dimmers and Timers: Use dimmers in hospitality areas like bars or cafes to create different moods, while timers ensure lights are only on when needed in less-frequented areas. 

Pro Tip 6: Timers and dimmers help reduce energy use during low-traffic hours, saving on operational costs. Energy.gov.au provides practical advice on energy-efficient lighting strategies here. 

Australian Standards and Compliance 

To ensure your containerised building meets safety and energy efficiency standards, make sure to select lights that comply with Australian regulations. Adhering to these standards ensures safe, reliable lighting installations and lowers long-term operational costs. 

• Energy Star Ratings: Choose fixtures with high Energy Star ratings for optimal energy efficiency, which is particularly valuable in high-use buildings like workshops and kitchens. 
• Building Code Compliance: Follow the Australian Building Code, which includes specifications for lighting in temporary and modular buildings. 

For more on compliance, refer to Australian Building Codes Board (ABCB) here. 

Light Up Your Containerised Space with Efficiency and Style 

Whether your containerised building serves as a functional site unit or a welcoming hospitality space, thoughtful lighting choices are essential for creating a well-lit, energy-efficient environment. From ambient lighting in lunchrooms and workshops to decorative accents in cafes and bars, selecting the right lighting enhances both functionality and atmosphere.
