During film formation, a paint must transform from a liquid material to a closed, strong, and beautiful coating. To give optimum protective and aesthetical properties, a coating should be smooth and without craters, pinholes, cracks etc. Defects can ruin the desired properties of coatings. A huge amount of time and money is invested in preventing and resolving defects. Preventing or resolving a defect is easier and faster when the phenomena that cause the defect, are known and understood. A wide variety of coating defects occur. In the following, only a few of them are briefly discussed.
