The problem
Industrial steel and concrete in Tema's port and warehouse environment corrode and abrade fast — and a protective system only lasts if it is matched to the right durability category and applied to a properly prepared substrate.
Our approach
Industrial Protective Coating
Specification-grade industrial protective coating by City Painting Ghana — corrosivity-category-matched systems, blast-graded preparation, and verified film build for steel and concrete in Tema's industrial environment.
The Challenge
Industrial assets in Tema work in one of the most aggressive coating environments in the country. A coastal, port-adjacent atmosphere combines salt-laden air, high humidity, and industrial exposure — conditions that drive corrosion on structural steel, cladding, tanks, and plant far faster than an inland commercial building ever sees. Concrete floors and structures in the same facilities face heavy abrasion, chemical spillage, and moisture loading. A protective coating here is not cosmetic; it is asset protection, and when it fails early the cost is measured in downtime and repair, not just repainting.
Most coating failures in this environment trace back to two decisions made before a tin is opened. The first is specifying a system that does not match the actual corrosivity of the exposure — under-specify, and the coating is overwhelmed within a fraction of its intended life. The second is applying that system over a substrate that was never prepared to the standard the coating needs to bond — and the best paint in the world will not adhere to mill scale, rust, or contamination. Both are avoidable with the right discipline, and both are routine where that discipline is absent.
The City Painting Ghana Solution
City Painting Ghana approaches industrial coating as a protective-engineering task. Each engagement begins with an assessment of the asset and its exposure — substrate type, condition, and the corrosivity of the environment — so the coating system is selected against the right durability target rather than a generic gloss. For steel in this setting, that means specifying to the ISO 12944 framework: classifying the atmospheric corrosivity category (typically C4 to C5 for Tema’s coastal-industrial exposure) and selecting a system rated for the required protection durability.
Surface preparation is treated as the load-bearing step. Steel is cleaned to the blast or preparation grade the system demands, assessed against ISO 8501 visual standards, before any primer is applied. The protective system is then built in specified coats — primer, intermediate, and finish — with dry-film thickness verified through the build so the installed system reaches its specified protection. For concrete substrates, surfaces are prepared and primed to the system requirement before protective or floor coatings are applied. The result is a coating engineered to survive its environment, not merely to cover it.
Documentation & Process Specification
Every industrial package is delivered with a technical record: an exposure and corrosivity assessment with the ISO 12944 category and target durability; the specified coating system and data sheets; surface preparation graded and recorded to ISO 8501; dry-film thickness verified to ISO 2808 across primer, intermediate, and finish coats; and stage QC sign-off through the build. The asset owner inherits a documented specification and verification trail that supports maintenance planning and warranty.
Typical Engagement Profile
These engagements typically cover structural steel, cladding, plant, tank exteriors, and concrete floors and structures across warehouses, logistics terminals, and industrial facilities in the Tema corridor. They run in coordination with the facility’s maintenance and operations functions, often phased around continuing plant operation — the kind of exposure-matched, specification-led delivery City Painting Ghana has run for industrial and commercial clients across Accra, Kumasi, and Tema since 1983.
Outcomes
- Coating systems matched to the real corrosivity of the Tema environment (ISO 12944)
- Substrates prepared to a graded standard so the system actually bonds (ISO 8501)
- Verified film build that delivers the specified protection durability (ISO 2808)
- A documented specification and QC record that supports maintenance and warranty
