Abstract
A method of coating an area of a wind turbine rotor blade comprises: defining an area to be coated on a surface of the blade, applying a first plurality of strips of masking tape to the surface of the blade proximate a first edge region of the defined area such that each strip is arranged adjacent to at least one other strip of said first plurality of strips, spraying a coating layer onto the defined area up to an innermost strip such that the innermost strip defines an edge of the coating layer, removing the innermost strip(s) to expose an uncoated region of the defined area between the edge of the coating layer and an innermost remaining strip and spraying a further coating layer over the previous coating layer and over the uncoated region up to said innermost remaining strip.

A method of coating an area of a wind turbine rotor blade, the method comprising:
- (i) defining an area to be coated on a surface of the blade;
- (ii) applying a first plurality of strips of masking tape to the surface of the blade proximate a first edge of the defined area such that each strip is arranged adjacent to at least one other strip of said first plurality of strips;
- (iii) spraying a coating layer onto the defined area up to an innermost strip such that the innermost strip defines an edge of the coating layer;
- (iv) removing the innermost strip(s) to expose an uncoated region of the defined area between the edge of the coating layer and an innermost remaining strip;
- (v) spraying a further coating layer over the previous coating layer and over the uncoated region up to said innermost remaining strip;
- and
- optionally repeating steps (iv) and (v) until a coating having a desired thickness is achieved.
A wind turbine blade comprising a leading edge protection coating covering a leading edge region of a surface of the blade, wherein the leading edge protection coating comprises:
- an outer coating layer;
- and
- at least one inner coating layer between the outer coating layer and the surface of the blade, wherein the outer coating layer extends beyond at least one edge of the at least one inner coating layer in a direction towards a trailing edge of the blade such that the leading edge protection coating tapers in thickness in a direction towards the trailing edge.
