Abstract
A covering element for walls, floors, ceilings or the outdoor area, including a carrier plate containing a mineral material, which carrier plate carries a polymer-containing decor layer on its front side, which covering element includes complementary recesses and protrusions extending at its lateral edges, wherein the recesses and protrusions are formed respectively on lateral edges facing away from each other, such that they engage each other when covering elements are situated next to each other, which recesses and protrusions are arranged in the carrier plate.
Claims15
A covering element, the covering element comprising:
- a carrier plate comprising a mineral material, wherein the carrier plate is formed as a flat mineral carrier plate with a content of cement larger than 35 percent by volume, wherein the carrier plate is multi-layered, wherein the carrier plate carries a polymer-containing decor layer on a front side of the carrier plate, wherein the carrier plate has a thickness between 3 and 15 mm;
- and
- complementary recesses and protrusions respectively on opposing lateral edges of the carrier plate of the covering element, such that in an assembled condition of two or more covering elements the complementary recesses and protrusions engage with each other,
- wherein an uppermost layer of the carrier plate is reinforced, at least at the opposing lateral edges comprising the recesses, by a portion of a polymer contained in the polymer-containing decor layer that penetrates into the uppermost layer over a depth greater than 0.1 millimeter.
A method for manufacturing a covering element, the method comprising:
- providing a carrier plate comprising a mineral material, wherein the carrier plate is formed as a flat mineral carrier plate with a content of cement larger than 35 percent by volume, wherein the carrier plate has a thickness between 3 and 15 mm;
- coating the carrier plate with a decor layer;
- and
- prior to or after providing the decor layer, on opposite lateral edges of the carrier plate, milling respectively recesses and protrusions for a tongue/groove connection,
- wherein the decor layer is a polymer-containing decor layer, wherein at least a part of the polymer-containing decor layer is applied in liquid form, and wherein a polymer contained in the polymer-containing decor layer penetrates into an uppermost layer of the carrier plate over a depth greater than 0.1 millimeter, at least at the opposite lateral edges comprising the recesses.
