Cracking
What it means
Cracks can develop when coating movement or stress exceeds the film’s ability to accommodate it. The substrate and coating system should both be investigated.
What to check
- Surface preparation and cleanliness
- Compatibility of previous and new coating
- Application method and film build
- Drying/curing conditions
- Manufacturer instructions and technical data
For a product-specific diagnosis, identify the exact product and surface and consult the current manufacturer guidance.
