Abstract
The present invention relates in general to a method of manufacturing fibre-reinforced parts for a wind power plant, such as a blade, in an open mould. More specifically the invention relates to a process step of applying at least one layer of gelcoat on a interior surface of said open mould prior to arranging at least one layer of material comprising fibre and to an arrangement that can be used in performing said method. The process step comprises to apply the gelcoat from a first end portion of the mould and to a second end portion of the mould and to cover the open mould from said first end portion to said second end portion gradually as gelcoat is applied.
