Late
drying
Reasons:
-The paint was applied on damp, dirty or greasy surface.
-Poor ventilation of the painted room.
-The applied paint was not stirred well.
Solution:
-During the drying there will be loss in brightness of the paint or dust
and dirty particles will accumulate on the surface. In this case after
the complete drying, the surface should be cleaned with appropriate sandpaper
and the last layer of painting should be repeated.
