(54) Method to increase the adherence between two surfaces


(57) The present invention refers to a method to increase the adherence between a relatively glossy surface, e.g. a steel surface and a substance which can be applied on or around said surface which is pourable and solidifies to a rigid form. The object of the invention is to provide a simple and a relatively cheap method to increase the adherence without that the glossy surface being exposed to deformations or weakenings, and which adherence should be accomplished on even surfaces as well as on single or double curved surfaces and also in recesses which are difficult to access. These objects have been solved by that a glossy surface which is provided with a glue layer or the like is coated in an electrostatic way, alternatively is coated with artificial fibres so-called fibre flocks, which are raised from the surface, covering an essential part of its surface, whereby the green concrete is applied against the fibre flock.
