wherein said at least one side edge comprises said lowered edge surface, wherein said at least one side edge is treated with the impregnation agent at a location vertically below said lowered edge surface, and at a location horizontally below the lowered edge surface; and
wherein the lowered edge surface is provided with a separate decorative surface layer from the decorative surface layer of a remainder of an upper surface of the floor board.
2. The floor board of claim 1 , wherein the lowered edge surface is in the form of a square edge, a beveled edge or a chamfered edge.
3. The floor board of claim 1 , wherein said at least one side edge comprises said lowered edge surface, wherein the impregnation agent is available at least 0.8 mm vertically below said lowered edge surface, as well as at a location horizontally below the lowered edge surface of said at least one side edge.
4. The floor board of claim 1 , wherein said first pair of opposite side edges comprises mechanical coupling parts allowing to couple said floor board at the respective edges with a similar floor board such that, in a coupled condition, said floor board and said similar floor board become locked both in a direction perpendicular to a plane formed by the coupled floor boards, as well as in a direction perpendicular to said edge and in said plane.
5. The floor board of claim 4 , wherein said mechanical coupling parts are basically shaped as a tongue and a groove, wherein said groove is delimited by an upper groove lip and a lower groove lip, and wherein said tongue and groove are provided with additional locking elements for creating said locking in the direction perpendicular to said edge and in said plane;
wherein said mechanical coupling parts allow for coupling of said floor board to said similar floor board, by a rotational movement or a horizontal shifting movement of one of said floor boards in respect to the other.
6. The floor board of claim 5 , wherein in said coupled condition, said lower groove lip is bent-out and pushes on said tongue to thereby push the coupled floor boards towards each other.
7. The floor board of claim 5 , wherein said additional locking elements comprise an excavation at the lower side of the tongue and a cooperating therewith protrusion at an upper surface of the lower groove lip.
8. The floor board of claim 1 , wherein both side edges of said first pair of opposite side edges are treated with said impregnation agent.
9. The floor board of claim 1 , wherein at least said second pair of opposite side edges comprises mechanical coupling parts allowing to couple said floor board at the respective side edges with a similar floor board by means of a downward motion such that, in a coupled condition, said floor board and said similar floor board become locked both in a direction perpendicular to a plane formed by the coupled floor boards, as well as in a direction perpendicular to the coupled side edges and in the plane of the coupled floor boards.
10. The floor board of claim 9 , wherein said mechanical coupling parts are basically shaped as a male part and a female part, wherein the male part is formed with a downwardly extending hook shaped part and the female part comprises a lower flank with an excavation provided therein; wherein said male part is designed to be seated in said excavation.
11. The floor board of claim 10 , wherein said female part further comprises an upwardly protruding hook shaped part bordering said excavation, and wherein said upwardly protruding hook shaped part cooperates with the downwardly extending hook shaped part of the male part.
12. The floor board of claim 10 , wherein the male part further comprises a sidewardly protruding hook and wherein said female part further comprises an undercut, said undercut preferably being formed by means of a separate insert, which insert resiliently moves inwardly and subsequently outwardly to catch the sidewardly protruding hook in the undercut during the downward motion.
13. The floor board of claim 1 , wherein said decorative surface layer is formed from at least one or more paper layers treated with a thermosetting resin; or at least one or more wood veneer layers.
14. The floor board of claim 13 , wherein said decorative surface layer is formed from at least one or more paper layers; and wherein said at least one or more papers are treated with a thermosetting resin.
15. The floor board of claim 1 , wherein said decorative surface layer comprises a print; wherein said decorative surface layer further comprises a wear resistant layer provided over the print.
16. A floor board comprising a substrate having side edges and a decorative surface layer applied to said substrate, said substrate comprising MDF or HDF material at at least one of said side edges,
wherein said at least one side edge is treated with an impregnation agent;
said at least one side edge together with a side edge opposite thereto forming a first pair of opposite side edges of said substrate;
wherein said floor board further comprises a second pair of opposite side edges;
wherein said first pair of opposite side edges or said second pair of opposite side edges comprises a lowered edge surface, produced by removing a material portion of the side edge;
wherein said at least one side edge comprises said lowered edge surface, wherein said at least one side edge is treated with the impregnation agent at a location vertically below said lowered edge surface, and at a location horizontally below the lowered edge surface; and
wherein the lowered edge surface comprises a surface of said substrate and is free from decoration.
17. The floor board of claim 16 , wherein the lowered edge surface is in the form of a square edge, a beveled edge, or a chamfered edge.
18. The floor board of claim 16 , wherein said at least one side edge comprises said lowered edge surface, wherein the impregnation agent is available at least 0.8 mm vertically below said lowered edge surface, as well as at a location horizontally below the lowered edge surface of said at least one side edge.
19. The floor board of claim 16 , wherein said first pair of opposite side edges comprises mechanical coupling parts allowing to couple said floor board at the respective edges with a similar floor board such that, in a coupled condition, said floor board and said similar floor board become locked both in a direction perpendicular to a plane formed by the coupled floor boards, as well as in a direction perpendicular to said edge and in said plane, wherein said mechanical coupling parts are basically shaped as a tongue and a groove, wherein said groove is delimited by an upper groove lip and a lower groove lip, and wherein said tongue and groove are provided with additional locking elements for creating said locking in the direction perpendicular to said edge and in said plane; and
wherein said mechanical coupling parts allow for coupling of said floor board to said similar floor board, by a rotational movement or a horizontal shifting movement of one of said floor boards in respect to the other.
20. The floor board of claim 19 , wherein in said coupled condition, said lower groove lip is bent-out and pushes on said tongue, the lower groove lip is arranged to push the coupled floor boards towards each other.
