In commercial and light industrial environments, paint has a much bigger job to do than simply make a surface look good.
Steel structures, machinery, concrete floors, warehouses and other commercial assets are constantly exposed to conditions that can shorten their lifespan. Moisture, UV exposure, chemicals, corrosion, pollution and everyday wear all take their toll.
This is where light industrial coatings become important.
Drawing on experience across the automotive, marine and industrial sectors, Dekro Paints offers specialised coating systems designed to protect demanding surfaces and extend maintenance cycles. From corrosion-resistant primers to epoxy coatings and protective metal finishes, the right system can make a significant difference to the long-term performance of an asset.
Why Choose Specialised Light Industrial Coatings?
Standard decorative paints work well for the environments they are designed for. However, commercial and industrial surfaces often face conditions that require a more specialised solution.
A steel structure exposed to moisture, for example, needs very different protection from an interior plastered wall. Similarly, a concrete floor exposed to regular traffic or chemical spills needs a coating system developed specifically for that environment.
Industrial coatings in South Africa must also contend with demanding climatic conditions, including strong UV exposure, coastal salt, temperature changes and moisture.
Specialised formulations are designed around factors such as:
-
Corrosion protection
Corrosion is one of the biggest threats to metal infrastructure. Industrial coating systems can be selected according to different corrosivity classifications, from lower-risk C1 environments through to demanding C5 conditions.
The correct combination of preparation, primer and topcoat helps protect steel and other metal surfaces against premature deterioration.
-
Strong adhesion
Industrial environments often involve challenging substrates such as structural steel, galvanised iron and concrete.
Specialised coatings and primers are formulated to create strong adhesion to these surfaces, helping the complete coating system perform as intended.
-
Longer maintenance cycles
Constantly repainting commercial infrastructure is disruptive and expensive.
Choosing a durable industrial coating system can help extend maintenance intervals, reduce premature coating failure and protect the underlying asset for longer.
Dekro Light Industrial Coatings for Demanding Applications
Dekro Paints offers a broad selection of light industrial paints, primers and protective coatings, allowing contractors and businesses to select products according to the surface, environment and required performance.
Some of the key solutions include:
Epicon Series and Dekro Tuffcoat
Epoxy coatings are widely used in industrial environments because of their toughness and resistance to demanding conditions.
The Dekro Epicon Series and Tuffcoat include high-build and surface-tolerant epoxy solutions designed to provide a durable protective barrier against moisture and chemical degradation.
These types of coatings are particularly valuable where ordinary architectural paints would not provide sufficient long-term protection.
Moisture-displacing coating systems
Concrete can present its own challenges, particularly where moisture is present within or around the substrate.
Dekro offers specialised systems incorporating hydrophobic resin technology, designed to provide reliable performance on correctly prepared concrete surfaces where baseline moisture may be present.
The result is a more specialised solution for challenging commercial and light industrial environments.
Primers and Protective Coatings for Metal
The performance of a metal coating system often begins long before the final coat is applied.
A suitable industrial metal primer creates the foundation required for adhesion, corrosion resistance and long-term protection.
Dekro offers a variety of specialised primers and protective coatings, including:
- Vasbyt
- Hydrobond 44
- Painter’s Pal Hydromet Rust Converter
- Vinyl Wash Primer
- UQD Zinc Phosphate Primer
- Dual Pack UQD Ermine Grey
- Flexicoat
- Self Priming Urethane (SPU)
- Metallic Zinc Rich Primer
- Adthane Enamel
Different products fulfil different roles within an industrial coating specification.
For example, zinc-rich coatings can provide a sacrificial galvanic defence to help protect steel against corrosion. Etch and wash primers can assist with adhesion to suitable metal substrates, while high-performance topcoats provide the final layer of durability and protection.
This is why selecting an industrial coating should be based on more than simply choosing a colour or finish. The complete coating system needs to suit the substrate and conditions in which it will operate.
Surface Preparation: The Golden Rule of Industrial Painting
You can invest in a high-performance coating, but if the surface underneath has not been correctly prepared, the system may still fail.
Surface preparation is one of the most important stages of any industrial painting project.
Concrete surfaces
Weak laitance, contaminants and poorly bonded material should be removed before coating.
Depending on the project requirements, preparation may include diamond grinding or shot blasting to create the correct surface profile and provide a sound substrate for the coating system.
Steel and metal surfaces
Rust, old coatings, mill scale and contamination can prevent primers and coatings from bonding correctly.
Where specified, professional abrasive blast cleaning may be required. Standards such as Sa 2½ involve very thorough blast cleaning to prepare steel for the appropriate protective coating system.
Oils, salts and biological contamination
Painting over grease, salts, fungal growth or other contamination simply traps the problem beneath the coating.
Surfaces should therefore be properly cleaned, degreased and treated where necessary before the coating system is applied.
Good preparation may take additional time at the beginning of a project, but it can make a considerable difference to coating performance and service life.
Choosing the Right Industrial Coating System
There is no single coating that is right for every industrial application.
Before choosing a product, consider:
- What is the substrate? Steel, galvanised metal and concrete all have different requirements.
- What will the surface be exposed to? Consider water, chemicals, UV, salt, pollution and abrasion.
- How severe is the environment? A protected indoor structure and exposed coastal steelwork require different levels of corrosion protection.
- What surface preparation is possible? The condition and preparation of the existing substrate will influence the coating specification.
- What finish and service life are required? Consider both appearance and long-term performance.
For more demanding applications, obtaining professional advice before selecting the coating system can help prevent expensive mistakes later.
