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.
