A decorative panel may have at least an upper visible surface that has a decorative pattern and an identification pattern. The identification pattern may be non-visible by the human eye and detectable by a detecting device. The decorative pattern may include at least one region having an average color having a saturation value. The identification pattern may be formed by a plurality of pattern elements distributed on at least a portion of the visible surface. The pattern elements may each have a color that has a different saturation value than the saturation value of the average color of the region of the decorative pattern wherein the plurality of pattern elements are situated.

A decorative panel includes at least a substrate and a decorative top layer. The substrate is or includes a board material having one or more layers of thermoplastic material. The decorative top layer at least has a decorative print. An intermediate layer is present intermediate the surface of an outermost layer of the substrate or board material and the decorative print. An outermost layer of the board material may be foamed and/or filled with hollow filler materials. A method suited for manufacturing such decorative panel.

A floor element includes a substrate made of polymer, a top layer on one of the two sides of the substrate and a polymeric foamed layer on the other of the two sides of the substrate. The density of the polymeric foamed layer is less than 120 kg/m 3 .

A floor covering includes an underlayment basic layer, at least one floor element and an adhesive layer. The adhesive layer is positioned in between the underlayment basic layer and the floor element. The underlayment basic layer includes fillers. The majority of the fillers have a Moh's hardness of 5 or less and/or the majority of the fillers is formed by CaCO 3 and/or talcum. The bottom of the underlayment is formed by a foil of polypropylene.

A set comprising a plurality of covering elements for floors and/or walls, wherein each covering element comprises an upper surface having a pattern and at least one distressed upper edge, wherein at least two covering elements of the set comprises substantially the same pattern, and wherein the shape of the distressed upper edge differs in each covering element of the set.

A decorative panel includes a substrate, a top layer and a top coating. The top layer is located between the substrate and the top coating. The uppermost surface of the top coating includes a randomized relief.

A board including a plurality of layers having a different composition. At least one of the layers is based on MgO and MgChloride and/or at least one of said layers is based on MgO and MgSulphate. Methods for manufacturing such boards, and methods for manufacturing coated panels include such board.

A use of dicyandiamide is provided as a modifier in a melamine-formaldehyde resin for use in a floor panel including a substrate and a top layer. The top layer defines an upper surface of the floor panel. The floor panel is provided with embossments extending from the upper surface, such that the thickness of the floor panel varies along a cross-section of the floor panel. The top layer has a modified melamine-formaldehyde resin including formaldehyde and melamine in an F/M molar ratio within the range of from 1.60 to 1.80, and at least one modifier, thereby providing a floor panel having improved transparency at the embossments.

A polymer floor element includes a decorative top layer on a substrate made of polymer. The floor element has a rectangular or square surface, for which it is valid that for a strip of the floor element with a first point Q defined as a vertex of the strip, and a point P at a distance of 40 cm with respect to Q along a side of the strip, suspended over a rod with diameter 2 cm with its side on which P and Q are defined, perpendicular to the axis of the rod, so that P is located in the vertical direction at the highest point where the floor element touches the rod. The strip, with point Q along one side, hangs down from the rod under the strip's own weight; the straight line PQ intersects the vertical through P at an angle less than 15°.

A method for composing a set of floor panels for flooring a room is based on a data set in accordance at least with the ground surface area of the room. The method includes the step of establishing a laying plan suitable for the room. The step of establishing a laying plan is carried out by means of a computer. The computer proposes a laying plan on the basis of the data set, taking into account desired limitations. The limitations are used to restrict a database of possible solutions.
