Abstract: The invention relates to a method of manufacturing a composite product, wherein a plurality of elements are assembled by gluing them together under pressure with a glue comprising at least one first component and at least one second component, which method further comprises controlling the relation between the second and the first components of the glue applied. The press time is often a limiting factor for the production capacity of a plant and renders the production planning difficult. The press time is affected not by the temperature of the elements, but also a great extent by the relation between the components in the glue and can be significantly decreased by increasing the amount of hardener compared to the amount of resin. According to the invention, it has been found that this can be utilised for controlling the gluing in a way so the production can be planned more efficiently.
