Abstract

A method of masking a mould (40) for moulding a wind turbine blade shell part (24, 26), the method comprising the steps of: arranging a masking device (50) in a mould (40) so that the masking device (50) covers the non-coating zone (46) of the mould surface (41), spraying a coating (70) onto a mould surface of the mould so that the coating is applied to a coating zone (44) of the mould surface (41) and prevented from being applied to a non-coating zone (46) of the mould surface (41) by the arrangement of the masking device (50), and removing the masking device (50) from the mould so that the non-coating zone (46) is exposed. The masking device (50) is configured so that, upon terminating spraying of the coating (70) at the first longitudinal boundary (45) of the coating zone (44), a lip portion (52) of the masking device (50) is separated from the coating (70) applied on the coating zone (44) by a gap (G).
