Many sided hallway that unforunately has ended with a board that is 1 1/2" wide (standard board is 4 1/2") at the stairs. This skinny board butts up length-wise to a stair riser. I realize that having such a skinny board (should be at least 2 1/4" wide) so instead of having it buckle/lift up because it's so narrow, I think a solution would be to glue that narrow cut board to it's long neighbour to create a 6" wide board (ans about 4 ft long) that can then be cut to go around the bottom riser and around a corner (the last step is rounded stair, not straight ended). If that makes sense. BTW, this is a floating engineered h/w floor (ie not nailed or glued down) EXCEPT fot this one board. Is this a plan or is there a better solution?
