Abstract
An applicator tool (40) for repairing damage (26) to a wind turbine blade (20) includes a spatula (42) including a flexible extrusion plate (44) and one or more spacers (60, 106) positioned proximate an inner surface (58) of the extrusion plate (44). The one or more spacers (60, 106) are configured to define a gap between an outer surface (34) of the wind turbine blade (20) and the inner surface (58) of the extrusion plate (44). A feed tube (86) is provided for supplying a coating material to the spatula (42), wherein the spatula (42) is configured to shape the coating material into a coating (30) over a damaged area (26) of the wind turbine blade (20).
