The problem
Most coating failures start at the substrate — institutional clients need preparation specified, graded, and recorded, not improvised before the paint goes on.
Our approach
Surface Preparation Systems
Surface preparation systems by Corporate Painters — substrate assessed, prepared to a graded ISO 8501 standard, and recorded, so the warranted finish sits on sound ground rather than a quick wash-down.
The Challenge
The most common reason a corporate finish fails early has nothing to do with the paint and everything to do with what it was applied over. A coating laid onto a contaminated, friable, or unsound substrate cannot adhere, no matter how good the product — and the failure, when it comes, looks like a paint problem but is a preparation problem. On landmark corporate buildings the substrates are varied: plastered masonry, concrete, previously coated surfaces with unknown compatibility, and structural steel each demand a different preparation, and getting it wrong on any of them undermines the warranty written over it.
A quick wash-down and a coat of paint is what produces the failures Corporate Painters is most often called to remediate. The substrate has to be assessed and prepared to a defined, recorded standard before the system goes on — otherwise everything above it is built on sand.
The Corporate Painters Solution
Corporate Painters treats preparation as a specified system in its own right, matched to the substrate and recorded before any coating is applied. Each surface is assessed for type, condition, contamination, and existing-coating compatibility, and a preparation method is specified to bring it to the standard the coating system requires. That standard is not a matter of opinion: surface-preparation grades are defined by ISO 8501, which sets the visual cleanliness a substrate must reach, and the prepared surface is verified against it rather than judged by eye.
Where the system depends on adhesion to a difficult substrate — a previously coated wall, or steel — adhesion is verified to ASTM D3359 so compatibility is proven, not assumed. The specified film of the coating system is then built and verified to ISO 2808 on a substrate that has been properly prepared to carry it. The result is a finish that holds because the ground beneath it was engineered, not improvised.
Documentation & Process Specification
Preparation is delivered as recorded evidence, because it is the foundation the warranty rests on. Each commission produces a substrate assessment by area; a preparation specification matched to each substrate type; surface-preparation grades verified and recorded to ISO 8501; adhesion test results to ASTM D3359 where compatibility is critical; and the preparation sign-off that gates the coating stage in the multi-stage QC regime. Dry-film thickness of the coating system above it is verified to ISO 2808. The client inherits proof that the warranted finish sits on sound, documented ground.
Typical Engagement Profile
Surface preparation is the foundation stage of every Corporate Painters commission, and is most critical on heritage corporate restorations, previously coated institutional buildings, and any work carrying a decade warranty. It is coordinated with the architect and facility team where existing-coating compatibility or substrate remediation affects scope, and run through the project office that has prepared and finished corporate-grade surfaces in Accra since 1990.
Outcomes
- Every substrate assessed and prepared to a graded, recorded standard before coating
- Preparation verified to ISO 8501, not judged by eye
- Adhesion proven to ASTM D3359 where compatibility is critical
- A warranted finish built on documented, sound ground — the failures designed out
