Abstract
A floor board including a decorative surface layer applied to a substrate, where the substrate is optionally MDF or HDF material at a side edge thereof, and at least one side edge together with a side edge opposite thereto forming a first pair of opposite side edges of said substrate. The first pair of opposite side edges includes mechanical first and second coupling parts, respectively, allowing the floor board to be coupled at the respective side edges with a similar floor board. Also, a floor board covering consisting of a plurality of the floor boards and a method for manufacturing such floor boards.
Claims29
A floor board, comprising:
- a substrate having a plurality of side edges;
- and
- a decorative surface layer applied to said substrate,
- wherein a side edge from the plurality of side edges, together with a further side edge from the plurality of side edges opposite thereto, forms a first pair of opposite side edges of said substrate,
- wherein said first pair of opposite side edges comprises first and second mechanical coupling parts, allowing to couple said floor board at respective side edges with a similar floor board by means of an angling down motion such that, in a coupled condition, said floor board and the similar floor board become locked both in a vertical direction perpendicular to a board plane defined by the intercoupled floor boards, as well as in a horizontal direction parallel to said board plane,
- wherein said first coupling part comprises a sideward tongue,
- wherein said second coupling part comprises a recess for accommodating at least a part of the sideward tongue of the similar floor board, said recess being defined by an upper lip and a lower lip, wherein the lower lip extends beyond the upper lip, and
- wherein the substrate comprises MDF or HDF material at the side edge,
- wherein the side edge is treated with at least one water barrier agent,
- wherein said water barrier agent is water impermeable and/or moisture-repellent, and
- wherein a concentration of said water barrier agent in a top section and/or a bottom section of the side edge is lower than a concentration of said water barrier agent in a centre section of the side edge.
