Mud Cracking

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.
