Abstract: The invention relates to a method for applying and molding a moldable coating compound (4), which is viscous during a predetermined application period and is cured once the application period has elapsed, onto a subsurface (2), in particular the outer skin of a watercraft, having the following steps: During the application period, the coating compound (4) is applied onto the subsurface (2); during the application period, a flexible planar substrate (6) is placed onto the applied coating compound (4); and, during the application period, a molding tool (8) is brought temporarily to bear on the substrate (6) to bring the surface (4a) of the coating compound (4) into a required shape.
