You love the look of your hardwood floor, and want to install new hardwood in the next room. But you're faced with a problem. The old floor was laid starting at the doorway where you want to add on, leaving the grooved edge where you want to begin your new flooring and need a tongue edge. There is a simple method to butt two grooved edges together and splice a new wood floor to an old wood floor.
Things You'll Need
- Hardwood flooring spline, enough to cover exposed edge of floor (available at flooring specialty supply stores)
- Miter saw
- Hardwood floor glue
- Rubber mallet
Cut a piece of spline the same length as the first piece of new wood that will connect to the old floor, using a miter saw. A spine is a thin piece of wood that fits into the grooved edge of a plank of hardwood. Once inserted, the outer edge of the spline will be the same length and thickness of the tongue, giving you a two-tongued plank of wood.
Run a thin bead of hardwood glue into the groove of the new piece of wood.
Place the spine into the glued groove immediately, tapping gently into place with a rubber mallet if necessary. Allow it to dry according to the glue manufacturer's directions. You now have a double-tongued piece of wood for your starter row.
Repeat the process with the remaining pieces of new wood for the connecting row.
Run a bead of glue onto the spline edge of the first new piece of wood.
Wedge the first piece of new wood into the groove on the exposed edge of old floor, gently tapping the edge with the wet glue into place with a rubber mallet if necessary. The piece is now ready to be nailed through the original tongue, as per normal installation.
Continue laying the splined starter row as before. You are now ready to install the rest of your new wood floor.
