A mould for moulding a wind turbine blade using a reinforcing material and a matrix material is provided. The mould includes a solid non-stick lining, and wherein the material properties of the non-stick lining are chosen to prevent a matrix material from bonding with the non-stick lining of the mould. A method of moulding a wind turbine blade in a mould is also provided. The method includes applying a solid non-stick lining to an inside surface of the mould, assembling a reinforcement material lay-up for the wind turbine blade on the non-stick lining, distributing a matrix material through layers of the reinforcement material lay-up, performing curing steps to harden the matrix material, and subsequently removing the cured wind turbine blade from the mould.
