Routing the last board is better than gluing and nailing it in place. Routing this board provides a much better joint and allows for natural and seasonal movement without breaking apart. If a glue bond fails, then you will end up with gaps. One method that works well is to install both sides of the field at the same time and work toward the middle. Working to the middle ensures that the outer edges are consistent and leaves the last board in the center. This ensures that you do not install the last, and most likely thinner, board next to the highly visible feature strip. When you get closer to the mid- dle, instead of finishing the field with one really thin narrow strip, you can always rip a little material off several boards and re-groove them to finish the floor without bringing attention to a much narrower strip. Usually, however, a slightly nar- rower board will not be picked up in the middle of the floor and is usually hidden under an area rug. For the last piece: On a table saw, rip the tongue off the second
With grooves cut into the ends, the final boards in the field should lock onto the tongue of the border.
It's a good idea to use con- struction adhesive to glue down the final center board.
Use a table saw to rip the tongues off the boards in the final row to finish the field. It may be necessary to rip the final row to a width that will fit.
You may need the assistance of a wood block to “persuade” the final board into place.
