A method for attaching an aerodynamic component to a wind turbine blade body during the manufacturing process. Firstly, a spacer element is attached to either the aerodynamic component or the wind turbine blade body. The aerodynamic component is then arranged at the portion of the blade body, and the first edge of the aerodynamic component is adjusted into a mounting position to minimize the step size between the aerodynamic component and the blade body. The aerodynamic component is temporarily fixed using the spacer element, creating a compartment between the aerodynamic component and the blade body. A first adhesive is injected into this compartment through injection ports in the aerodynamic component, with the spacer element acting as a barrier to prevent the adhesive from leaking out. Finally, the adhesive is allowed to cure, permanently fixing the aerodynamic component in place.
