Abstract

A wind turbine blade includes a protective cover attached along the blade by a layer of adhesive. The adhesive is a general purpose adhesive, and the adhesive forms a joint or sealing between an outer edge of the cover section of the blade and the surface of the blade so that the outer edge is covered by the adhesive and so that the joint forms an oblique surface from the outer edge to the surface of the blade. The joint has a first height at the outer edge and a second height at the position where it ends at the surface of the blade. The second height is smaller than the first height and smaller than 0.2 millimetres, and the joint is integrally formed with the layer of adhesive.
