Lack of Hiding
When after drying, the paint fails to hide the underlying colour or surface, on which it has been applied, the defect is called Lack of Hiding.
|Higher reduction of paint||Add fresh and unreduced material to balance reduction.|
|Application on very Hot, Smooth surface that tends to cause the finish to Flow off||Use a fast evaporating solvent|
|The slow evaporating solvent causing too much flow||Use a fast evaporating solvent.|
|Improper Stirring of Pigment into suspension, making it settle to the bottom||
• Stir before use and check if the pigment is evenly distributed.
• Check for low film build.
|Edges of the surface show through||Round the edges as they might be sharp|
|Improper atomization||Adjust the spray equipment|
|No matching of the standard paint color. The base color is showing through topcoat. Basically, low thickness||
• Apply more paint to achieve full hiding using spray gun.
• Colour the base coat with same topcoat colour for extra hiding.
• If the pigments used are organic, make thicker film as they lend poor hiding.
