Abstract
On the surface (5) of the floor covering micro-craters (6) statistically distributed are produced by the effect of laser impulses, which are invisible to the human eye and have a suction pad effect. In a second process stage, the surface of the thus produced laser-structured floor covering is subjected to a hydro-mechanical post-treatment. The hydro-mechanical post-treatment is only carried out in the cavities (6) of the floor covering or plates. This treatment is so effected that the surface of the laser-structured floor covering is at least twice sprayed with fluid, whereby the last spraying process serves to clean and/or neutralise the surface of the covering or plates of previous spray fluids. ADVANTAGE - Process increases slip-preventing effect.
