Abstract: The finishing assembly for floor covering comprises at least two bars (1;2/1;3), being on the one hand assembled together side by side such that they comprise at least two surfaces (1d;2d/1d; 3d) substantially in the prolongation of one another, and separated by a longitudinal interstice (6/6?), and being, on the other hand, separable. Both assembled bars (1;2/1;3) are designed to be used in a first floor covering application and at least one (1) of said two bars are designed to be used in a second floor covering application. The assembly further comprises a surface coating (4) being applied on both bars (1;2/1;3) and covering the longitudinal interstice (6/6?) between both bars.
