Abstract
A method for covering a screw head of a screw which penetrates through a workpiece surface in a sealed manner by means of a viscous coating material is disclosed. The method includes the steps of applying a first strip of the viscous coating material onto the workpiece surface at a first inclination relative to the workpiece surface, the first strip of the viscous coating material, after having been applied, at most partially covering the screw head; and applying a second strip of the viscous coating material to the workpiece surface at a second inclination relative to the workpiece surface, the second strip of the viscous coating material, after having been applied, overlapping the first strip in such a way that the screw head is fully covered, the first inclination and the second inclination being opposite one another. The invention furthermore relates to an application system.
