Abstract
The invention relates to a method of manufacturing non-slip floor coverings made of mineral materials, such as, for example, natural stone, fine stoneware, artificial stone or ceramics. This method is carried out in a two-stage process, there being produced on the surface of the floor coverings or slabs, in a first process stage by means of pulsed laser bombardment, statistically distributed microcraters invisible to the human eye. The surface of the floor coverings or slabs obtained in this way is then, according to the invention, subjected to hydromechanical aftertreatment.
