What surfaces is this sealant not suitable for?

Troubleshooting
Sealant is not adhering to the surface.
Ensure the surface is clean, dry, and free of any contaminants. Use a primer if recommended for the specific surface.
Sealant is cracking after application.
Ensure the sealant is compatible with the surface and that the movement capability (up to 25%) meets the needs of the application. Also, allow full curing time before exposing the sealant to water or other substances.
