Also a method for manufacturing such floor boards. ## Claims ### Claim 1 A floor board comprising a decorative surface layer applied to a substrate, wherein said substrate comprises MDF or HDF material at a side edge thereof, wherein said side edge is treated with a sealing agent; wherein the sealing agent is based on a superabsorbing material, said superabsorbing material comprising crystals of polyacrylate, or the sealing agent relates to particles of bentonite clay, amorphous silica or fuller earth, such as palygorskite and/or attapulgite. ### Claim 2 (depends on 1) The floor board of claim 1, wherein said side edge of said substrate is treated with an impregnation agent. ### Claim 3 (depends on 2) The floor board as in claim 2, wherein said impregnation agent comprises a solvent, wherein the solvent is different from water. ### Claim 4 (depends on 3) The floor board of claim 3, wherein said solvent is chosen from the list consisting of a butylacetate or propylacetate, such as 3-Methoxy-3-Methyl-1-Butylacetate (MMB-AC) or 1-Methoxy-Propylacetate (MPA), a dibasic ester, a glycol ether or glycol diether, such as Dipropylene Glycol Dimethyl Ether, a benzoate ester, such as that sold under the name Prifer 6813, or, a tetramethoxyether, such as Ethane,1,1,2,2-tetramethoxy-. ### Claim 5 (depends on 1) The floor board as in claim 1, wherein said MDF or HDF material comprises wood fibers glued by means of ureum formaldehyde glue or melamine ureum formaldehyde; and wherein said MDF or HDF material has an average density of more than 750 kg per cubic meter and comprises a higher density region at least near said decorative surface layer, wherein said higher density region has a density of 900 kilograms per cubic meter or more. ### Claim 6 (depends on 2) The floor board as in claim 2, wherein said impregnation agent at least penetrates the MDF/HDF material immediately below said decorative surface layer. ### Claim 7 (depends on 2) The floor board as in claim 2, wherein said impregnation agent comprises at least a substance chosen from the list consisting of an epoxy resin, a fluorocopolymer and acetic anhydride. ### Claim 8 (depends on 1) The floor board as in claim 1, wherein said floor board at said side edge as well as on a side edge opposite thereto comprise mechanical coupling means allowing to couple said floor board at the respective edges with a similar floor board such that said floor board and said similar floor board become locked both in a direction perpendicular to said decorative surface layer, as well as in a direction perpendicular to said edge and in a plane formed by said decorative surface layer. ### Claim 9 (depends on 8) The floor board as in claim 8, wherein the sealing agent seals the joint between the adjacent edges of said floor board and said similar floor board; wherein said sealing agent creates a sealing between the adjacent edges of said floor board and said similar floor board at the height of the lateral edge of said surface layer, or immediately underneath it, namely less than 1 millimeter under said surface layer. ### Claim 10 (depends on 8) The floor board as in claim 8, wherein said mechanical coupling means are basically shaped as a tongue-in-groove coupling provided with additional locking means for creating said locking in the direction perpendicular to said edge and in the plane of the panels; wherein said mechanical coupling means allow for creating a tension force pushing the coupled floor board towards each other, by means of a bent-out lower groove lip that pushes on said tongue. ### Claim 11 (depends on 1) The floor board as in claim 1, wherein the floor board comprises a first pair of opposite side edges and a second pair of opposite side edges; wherein said first pair of opposite edges comprise mechanical coupling means allowing to couple said floor board at the respective edges with a similar floor board such that said floor board and said similar floor board become locked both in a direction perpendicular to said decorative surface layer, as well as in a direction perpendicular to said edge and in a plane formed by said decorative surface layer; wherein said mechanical coupling means are basically shaped as a tongue-in-groove coupling provided with additional locking means for creating said locking in the direction perpendicular to said edge and in the plane of the panels; wherein said mechanical coupling means allow for creating a tension force pushing the coupled floor board towards each other, by means of a bent-out lower groove lip that pushes on said tongue; wherein said second pair of opposite edges comprise mechanical coupling parts allowing for a coupling by means of a downward motion of two such floor boards at their second pair of opposite edges, such that the two such floor boards become locked both in a direction perpendicular to said decorative surface layer, as well as in a direction perpendicular to said edge and in a plane formed by said decorative surface layer; wherein the first pair of opposite side edges and the second pair of opposite side edges of said substrate are treated with an impregnation agent. ### Claim 12 (depends on 1) The floor board as in claim 1, wherein the sealing agent has been applied immediately underneath the decorative surface layer, optionally overlapping therewith. ### Claim 13 (depends on 1) The floor board as in claim 1, wherein the sealing agent is adhered to the surface of said side edge by means of a hydrophobic acrylate and/or a photo curing acrylate, such as UV curing acrylate.
