Industrial environments pose unique challenges for maintaining exterior paint finishes. Exposure to harsh weather conditions, pollutants, and heavy machinery can take a toll on the appearance and integrity of exterior surfaces.

To help set you up for success the next time you’re contracted to work on an industrial project, such as a concrete tank or steel bridge girders, let’s look at eight tips for preserving the longevity and appeal of the exterior paint.

1. Choose the Right Paint or Coating

The foundation of a durable exterior paint job in an industrial environment begins with selecting the appropriate paint or coating. Opt for high-quality, industrial-grade paints that are designed to resist corrosion and withstand severe weather conditions. Also, think about using specialty paints, such as epoxy or polyurethane, because they can add an extra shield against chemicals and abrasions.

2. Devote Time to Surface Prep

Before applying any paint, thorough surface preparation is essential. Industrial surfaces often accumulate dirt, rust, and other contaminants that can hinder paint adhesion. Invest time in cleaning, sanding, and priming the surfaces to ensure proper bonding. You may need to prep chemically, too. This step not only enhances the longevity of the paint job but also contributes to a smoother and more appealing finish.

3. Schedule Regular Industrial Maintenance and Inspections

Frequent inspections are crucial for identifying early signs of wear and tear. Work with your current and potential clients to regularly check for peeling, cracking, or fading paint. Industrial coating services maintain asset integrity with expert evaluations and solutions. Exterior paint maintenance may include repainting and touch-up painting — especially in high-traffic areas prone to abrasion — and repairing small damages before they escalate into more significant problems.

4. Add Protective Sealants

Consider applying protective sealants in addition to high-quality paints and coatings. These sealants act as an extra barrier against moisture, pollutants, and ultraviolet (UV) rays, further safeguarding the exterior paint from deterioration. Sealants are particularly effective in areas prone to heavy rain or extreme sun exposure.

5. Invest in Anti-Graffiti Coatings

In industrial settings, graffiti can be a common challenge, affecting both the appearance and integrity of exterior paint. Anti-graffiti coatings offer a proactive solution by creating a protective layer. This makes it easier to “erase” unwanted markings without harming the paint underneath. This not only preserves the aesthetic appeal but also simplifies maintenance efforts.

6. Consider Thermal Insulation Coatings

For industrial facilities facing temperature extremes, thermal insulation coatings (TICs) offer a dual benefit. Not only do they contribute to energy efficiency by helping to regulate internal temperatures, but they also provide an additional layer of protection for exterior paint and potentially for people and other living beings present around it. TICs act as a barrier against heat and cold, preventing premature deterioration caused by thermal stress.

7. Implement Preventive Measures Against Corrosion

Corrosion is a common adversary in industrial environments. To combat this, incorporate preventive measures for your client, such as cathodic protection systems or sacrificial anodes. These measures help inhibit the corrosive process, preserving the structural integrity of surfaces and, consequently, the longevity of the exterior paint.

8. Opt for Low-VOC Paints for Environmental Considerations

In environmentally conscious industrial settings, opting for paints and coatings with low volatile organic compounds (VOCs). These paints give off less harmful fumes when applied, making the workplace healthier. In most cases, low-VOC paints are equally effective in protecting exterior surfaces while aligning with sustainability goals.

Answering Frequently Asked Questions

● How often should exterior paint be inspected in industrial settings? It’s suggested to have regular checks — at least twice per year — to spot any problems early and to avoid major damage.

● Are industrial coatings only necessary for specific industries? No, industrial coatings benefit a wide range of industries by providing enhanced protection against environmental factors and extending the lifespan of exterior paint.

● Can industrial coatings be applied to existing paint? Yes, industrial coatings can be applied over existing paint to reinforce protection and improve durability — as long as the coating is manufactured for this type of application.

● Are there specific sealants suitable for industrial environments? Yes, industrial-grade sealants are available and designed to withstand the challenges posed by industrial settings, including exposure to harsh weather and pollutants.

● How long does an anti-graffiti coating last? The longevity of anti-graffiti coatings varies but they generally offer durable protection for several years. Periodic reapplication may be necessary, depending on factors such as weather conditions and frequency of graffiti.

● Can thermal insulation coatings be applied to different types of surfaces? Yes, you can use thermal insulation coatings on many surfaces, such as metal, concrete, and masonry.

Strategic Decisions

Maintaining exterior paint in industrial environments requires a strategic approach, from product selection to application. Help your clients by providing specific solutions to tackling the difficulties in industrial areas. By using these tips and your professional expertise, you can offer solutions to your clients that offer exterior paints and coatings that can last longer and looks better — even in tough industrial settings.
