How systematic inspection, testing and documentation can turn visible defects into durable corrective action

When a Floor Fails, Start With Evidence
Even with careful planning and installation, resin flooring defects can occasionally occur. The critical question is not simply what the defect looks like, but why it happened. A structured troubleshooting process helps distinguish moisture-related failures from other causes and guides the selection of the most effective corrective action.
The strongest investigations are systematic: review project documentation, inspect the floor, speak with installation personnel, examine environmental conditions and analyse available moisture-testing results before drawing conclusions.
Moisture-Related vs. Non-Moisture-Related Defects
Moisture-related defects can include blistering, osmotic blistering, delamination, bubbling, whitening, soft coatings and microbial growth beneath the flooring system.
Not every failure, however, is caused by moisture. Poor surface preparation, incorrect mixing ratios, contamination, excessive film thickness, inadequate curing conditions and mechanical damage after installation can produce similar symptoms.
Investigate the Root Cause — Not Just the Symptom
A professional investigation should determine whether the primary cause is substrate moisture, contamination, material selection, workmanship, environmental conditions or service conditions. Corrective work should address that underlying cause rather than only the visible defect.
Diagnostic Techniques That Strengthen the Investigation
- Visual inspection and defect mapping
- Chain-drag or hammer sounding
- Pull-off adhesion testing
- Concrete moisture testing
- Coating-thickness measurements
- Infrared thermography where appropriate
- Laboratory analysis of samples when necessary
From Diagnosis to Corrective Action
Depending on the findings, repairs may involve localised removal, complete coating replacement, additional surface preparation, crack repair, moisture-mitigation systems or changes to installation procedures. Flooring-manufacturer recommendations should remain part of the repair decision.
Quick Failure-Analysis Reference
| Observed Defect | Possible Cause | Recommended Investigation | Typical Corrective Action |
| Blistering | Excess slab moisture | ASTM F2170 RH testing | Mitigate moisture and replace affected coating |
| Delamination | Poor preparation or moisture | Adhesion and moisture tests | Remove unsound coating and reprepare substrate |
| Pinholes | Air/moisture release | Inspect substrate porosity | Reprime and recoat after preparation |
| Whitening | Condensation or curing issues | Review environmental records | Correct conditions and refinish if required |
Prevention Is Better Than Remediation
Many failures can be reduced through proper specification, qualified installers, recognised moisture testing, environmental monitoring, disciplined QA/QC procedures and complete project documentation.
Every failure should also become a learning opportunity. Record the findings, update procedures, train personnel and carry the lessons into future projects.
PFS GHANA BEST PRACTICE
Never assume the cause of a defect. Base conclusions on evidence collected through inspections, recognised testing methods and documented project records.
The Key Takeaway
Effective troubleshooting combines inspection, testing and documentation to identify the true cause of flooring defects. Durable repairs come from correcting the root cause—not merely treating the symptom.
