Durable Painting for Industrial Applications: Ensuring Long-Term Durability Through Proper Training


When it comes to protecting large-scale industrial structures, durable painting is essential for ensuring longevity and structural integrity. Whether it’s oil rigs, pipelines, wind turbines, or manufacturing plants, industrial coatings are a vital defence against wear and tear, corrosion, and environmental damage. However, achieving a long term, durable finish requires more than just slapping on any old paint—it demands the right skills, techniques and knowledge, which come from proper training and experience.


At Dangle, we understand the critical role of high-quality, durable painting in industrial applications. We are the exclusive provider of the Train the Painter programme in Northern Ireland, designed to equip both novice and experienced painters with the skills needed to achieve durable finishes in industrial settings. This blog post will delve into the essential industrial painting techniques that ensure durability, highlight the importance of specialised training, and demonstrate how the Train the Painter programme helps technicians master these skills.



The Importance of Durable Painting in Industrial Applications


In industrial settings, durable painting serves multiple purposes that are key to the longevity and safety of the equipment and infrastructure:


Corrosion Protection

Corrosion at sea is one of the most significant threats to the structural integrity of industrial equipment offshore. Factors like moisture, salt, chemicals, and temperature fluctuations can accelerate corrosion, leading to costly repairs and unsafe working conditions. Durable painting creates a protective barrier that helps to prevent corrosion and extend the lifespan of vital industrial assets, whether thats onshore or offshore.


Resistance to Wear and Tear

Industrial environments often involve heavy machinery and equipment subjected to constant use, friction, and physical impact. A durable industrial coating ensures these surfaces can withstand abrasion, impact, and heavy wear while maintaining both their aesthetic and functional properties.


Environmental Protection

Many industrial sites—such as oil rigs, offshore platforms, and power plants—are exposed to harsh weather conditions, UV rays, and airborne pollutants. High-quality industrial coatings offer resistance to these environmental factors, ensuring long-term protection and reducing the frequency of maintenance and repairs.


Improved Aesthetics

While functionality is the primary concern, industrial sites also require a professional appearance. A well-applied, durable painting task enhances the appearance of industrial structures, contributing to workplace pride, customer-facing operations, and an overall positive company image. 


Cost-Effectiveness

Durable painting reduces the need for frequent maintenance and reapplication of coatings. While the initial investment in high-quality coatings might be higher, the longevity and protection they provide offer a significant return on investment by reducing long-term repair and upkeep costs.



Techniques for Achieving Durable Painting in Industrial Settings


To ensure a durable and long-lasting paint campaign, it’s essential to follow proper techniques at every stage of the application process. Below, we’ll explore key steps to ensure durable painting results in industrial environments to steel surfaces:


Surface Preparation

Surface preparation is arguably the most critical step in achieving durable paint finishes. The success of any industrial painting project depends on how well the surface is cleaned and prepared before applying paint. Any dirt, rust, old coatings, or oils left on the surface can hinder adhesion, leading to premature paint failure.


  • Abrasive Blasting: Often referred to as shotblasting or sandblasting (although sand blasting is illegal in the UK due to health and safety risks from silica sand). The technique uses abrasive materials like shot or steel grit to clean and prepare surfaces. Abrasive blasting is particularly effective for metal surfaces, ensuring that the paint will adhere well and that any rust or contamination is removed.


  • Power Washing: Power washing (using high-pressure water at 2500psi to 3500psi) is often sufficient to remove dirt, oil, and old, loosely adherent coatings. It’s a relatively quick and effective method for preparing large areas, although will not provide the steel substrate with a anchor profile where exposed steel exists.


  • Chemical Cleaning: In cases where grease, oils, or other stubborn contaminants are present, chemical cleaning agents like AkzoNobels and International Paints Interplus 4101 cleaning gel are used to break down and remove these substances, including light rust. This ensures that the surface is as clean as possible before the painting process begins.


A properly prepared surface allows the paint to bond more effectively, ensuring that the finished product is durable and long-lasting.


Paint Priming Application


Priming is essential for enhancing adhesion between the substrate and the topcoat. A primer acts as a preparatory coating that helps the paint to adhere better and also offers additional protection, such as corrosion resistance through the use of pigments such as zinc.


  • Epoxy Primers: These are often used for metal surfaces and offer excellent protection against corrosion. Epoxy primers are highly durable and ideal for use in harsh environments like marine or offshore platforms.


  • Zinc-Rich Primers: These primers are ideal for steel surfaces, providing a protective layer against rust and corrosion. They are often used in applications where rust resistance is critical and take the form of sacrificial mitigation.


By selecting the right primer, you ensure that the compatible topcoat, adheres properly and performs optimally over time within the paint system.


Top Coating Paints


The topcoat is the final layer of paint that provides the surface with its primary protective properties. This layer is responsible for offering resistance to wear, corrosion, UV radiation, and environmental elements. Choosing the right type of topcoat is essential for achieving durable painting results.


  • Polyurethane Coatings: Known for their exceptional UV resistance and durability, polyurethane coatings are ideal for outdoor industrial applications. These coatings provide a glossy finish that also offers excellent resistance to abrasion and colour retention.


  • Epoxy Coatings: Epoxy-based topcoats are highly resistant to chemicals, corrosion, and wear, making them suitable for environments where machinery and equipment are exposed to harsh chemicals or extreme temperatures.


  • Acrylic Coatings: Acrylic topcoats are ideal for environments where UV protection and aesthetics are important. They are commonly used in industrial settings exposed to sunlight, as they are resistant to UV degradation and environmental pollutants.


Proper application of the topcoat ensures that the paint performs as expected, providing long-term protection against environmental damage, wear, and corrosion.



Durable Painting Application Methods: Spray Painting vs. Brush and Roll


The method of application can affect the durability and overall quality of the finished paint job. The two most common methods for applying industrial coatings are spray painting and brush-and-roll techniques.


  • Spray Painting: Spray painting is the most widely used method for large industrial surfaces. It offers smooth and even coverage and is particularly effective for complex shapes or hard-to-reach areas. Spray painting is faster and provides a uniform finish, making it an excellent choice for industrial environments where large-scale application is required.


  • Brush and Roll: While less efficient than spray painting, brush-and-roll methods are ideal for smaller areas, touch-ups, or when a more precise application is needed. However, brush and roll techniques may not always deliver the same level of uniformity as spray painting, which can affect the long-term durability of the finish.


Choosing the correct application method is crucial to achieving durable painting results. For large projects, spray painting typically offers the best coverage and durability.


Paint Curing and Paint Drying


Curing and drying are the final stages of the painting process and are essential for ensuring that the coating achieves maximum durability. While drying refers to the process of the paint solidifying, curing is a chemical reaction that hardens the coating and increases its strength.


Different coatings require different curing conditions, such as specific temperature and humidity levels. Failing to allow the proper curing time or applying paint in unsuitable conditions can result in a coating failures and premature breakdowns.


Allowing the paint to fully cure ensures that the surface achieves optimal resistance to abrasion, corrosion, and environmental elements.



The Role of Training in Achieving Durable Painting
