A guiding element at a joint between boards, the joint including groove and tongue preferably intended to be joined by the use of glue. The tongue includes at least one guiding wedge. A fitting clearance between the tongue and the groove includes a first fitting clearance and a second, guiding, fitting clearance. The second, guiding, fitting clearance is obtained through the guiding wedges which are arranged parallel to the extension of the joint. The first fitting clearance comprises the main part of the fit and the second, guiding fitting clearance comprises a smaller part of the fit. The first fitting clearance is in the range 0.1-1 mm, while the second, guiding, fitting clearance is in the range 0.01-0.2 mm. The tongue of the joint is provided with at least one equalizing recess so that at least one equalizing cavity is formed in the joint, which equalizing cavity receives surplus glue used during the joining.

The invention claimed is: 1. A joint formed at a junction between adjacent boards, the joint comprising: a first board, comprising an upper surface, a lower surface and a groove; a second board joined to the first board, and comprising an upper surface, a lower surface and a tongue, said upper surface of said first board and said upper surface of said second board abutting each other; a first equalizing cavity located adjacent to an upper end of a proximal end of the tongue below said abutting surfaces; wherein a distal end of the tongue is smaller than a proximal end of the groove; a second equalizing cavity, formed by a gap between the proximal end of the groove and the distal end of the tongue; and further comprising glue disposed in at least one of the first equalizing cavity and the second equalizing cavity. 2. A joint formed at a junction between adjacent boards, the joint comprising: a first board, comprising an upper surface, a lower surface and a groove; a second board joined to the first board, and comprising an upper surface, a lower surface and a tongue, said upper surface of said first board and said upper surface of said second board abutting each other; a first equalizing cavity located adjacent to an upper end of a proximal end of the tongue below said abutting surfaces; wherein a distal end of the tongue is smaller than a proximal end of the groove; a second equalizing cavity, formed by a gap between the proximal end of the groove and the distal end of the tongue, wherein at least one of the first equalizing cavity and the second equalizing cavity extends to the lower surface of the second board. 3. A joint formed at a junction between adjacent boards, the joint comprising: a first board, comprising an upper surface, a lower surface and a groove; a second board joined to the first board, and comprising an upper surface, a lower surface and a tongue, said upper surface of said first board and said upper surface of said second board abutting each other; a first equalizing cavity located adjacent to an upper end of a proximal end of the tongue below said abutting surfaces; wherein a distal end of the tongue is smaller than a proximal end of the groove; a second equalizing cavity, formed by a gap between the proximal end of the groove and the distal end of the tongue, wherein the tongue comprises at least one guiding wedge on an upper surface or a lower surface thereof, whereby the at least one guiding wedge contacts an inner surface of the groove. 4. A joint formed at a junction between adjacent boards, the joint comprising: a first board, comprising an upper surface, a lower surface and a groove; a second board joined to the first board, and comprising an upper surface, a lower surface, and a tongue, said upper surface of said first board and said upper surface of said second board abutting each other; and said first board and said second board defining a gap therebetween; and a hole, in fluid communication with said gap, said hole having an opening below said groove. 5. The joint of claim 4, wherein said hole extends from said joint towards a proximal section of said first or second boards. 6. The joint of claim 4, wherein said hole extends towards said lower surface of said first or second board. 7. The joint of claim 4, wherein said hole is a vent through one of said boards. 8. The joint of claim 7, wherein said vent has a terminal end at said lower surface of said board. 9. A method for assembling floor boards to form a joint therebetween, the method comprising: providing: a first board, said first board comprising an upper surface, a lower surface and a groove; a second board joined to the first board, and comprising an upper surface, a lower surface, and a tongue; and glue, disposed on at least one of said tongue and said groove; mating said groove of said first board with said tongue of said second board; and directing said glue away from said upper surface and towards the lower surface of said boards.
