A covering element comprising a mineral material and carrying on its front side a polymer-containing decorative layer, the covering element comprising complementary recesses and projections extending on its side edges, wherein the recesses and projections are formed respectively on side edges facing away from one another, so that the recesses and projections engage into one another when covering elements are adjacent, the recesses and projections being disposed in a carrier plate, the carrier plate comprising mineral elements in a form of flour or particles, wherein the mineral elements comprise gypsum and or cement.
A method for producing a covering element, wherein a carrier plate comprising a mineral material is coated with a decorative layer, wherein, before or after application of the decorative layer, recesses and protrusions for a tongue-and-groove connection are generated by milling on side edges of the carrier plate that face away from one another, wherein the carrier plate comprises mineral elements in a form of flour or particles, wherein the mineral elements comprise gypsum and or cement.
