Abstract:
Method for manufacturing non-slip floor coverings or floor slabs, the non-slip floor coverings or slabs made of mineral materials having depressions in a 2-stage process by means of pulsed laser bombardment, there being produced, statistically distributed, on the surface of the floor covering, through the targeted action of laser pulses, microcraters acting like suction cups which are invisible to the human eye, characterized in that, in a second process stage, the surface of the laser-structured floor coverings or slabs so produced is subjected to purposeful hydromechanical post-treatment, it being represented that the hydromechanical post-treatment comes about in such a way that the surface of the laser-structured floor coverings or slabs is sprayed with liquid at least twice providing at least two spraying operations, at least one spraying operation serving to etch parts of the surface of the microcraters and thus enlarge same, and wherein of the at least two spraying operations, the last spraying operation serves to at least one of clean and neutralise the surface of the floor coverings or slabs from previous spray liquids.
