Abstract
A method for evaluating a coating sag includes the steps of determining a coating thickness on a specific coating surface, evaluating an inclination of the specific coating surface, determining a criticality of a coating sag on a vertical surface at which a coating sag is produced and evaluating whether or not a coating sag is produced on the specific coating surface based on the inclination of the specific coating surface and the coating thickness on the specific coating surface in view of the criticality on the vertical coating surface as a reference. It is possible to determine coating conditions which can effectively prevent a coating sag during the coating action even if it is made on an inclined coating surface.
