Mud-cracking is a common problem that occurs in the accurate application of coatings.
What visual appearance does mud-cracking take?
Mud-cracking appears as thousands of tiny splits or cracks in the coating surface resembling dried mud.
What probable causes are there for mud-cracking?
- The coating has been applied too thickly (Note: this condition most often occurs in waterborne coatings)
- Coating flashed too quickly or too high a temperature
What suggested solutions can solve the problem?
- Reduce the application viscosity
- Apply a thinner film
- Check flashing process
Support programs, free testing facilities and application advice are often made available from coating manufacturers, helping prevent problems early in the process, saving time and money.
