How to Replace Wood on a Hardwood Floor
- 1). Lay your replacement board on a work area. Set your circular saw on it, with the blade of the saw hanging over the edge of the board. Set the blade depth at the thickness of the wood (usually about ¾ inches).
- 2). Position the saw so the blade is facing in the same direction as the damaged board and sitting in the middle of it. Hold back the blade guard and set the front end of the flat blade plate to the surface. Tilt the saw forward so the blade isn't touching the wood.
- 3). Start the saw. Slowly lower the blade into the wood. Push the saw forward, cutting a line along the length of the board. Don't let the blade touch the edge of the board.
- 4). Repeat the process several times, running the saw forward over the board again and again, letting the lines cross each other, until pieces of the board start coming out. Cut out as much of the middle of the board as you can without touching the edges of it.
- 5). Set the edge of your chisel on the edge of the board and tap the edge inward, toward the cut-out middle, using your hammer. Knock the edges of the board inward on both sides, off the tongue-and-groove fittings of the adjacent boards. Get the damaged board completely out.
- 6). Set the replacement board on your work surface, face down. Cut off the bottom lip of the grooved edge of the board, using your utility knife. Put a bead of carpenter's glue along the bottom of the tongue and inside the groove.
- 7). Set the replacement board in the space, setting the tongue of the replacement board into the groove of one neighboring board, then dropping the grooved side of the replacement board over the tongue of the board on the other side. The altered groove will allow it to drop over the tongue.
- 8). Nail down the board with your finish nailer, putting them along the edges of the board every foot or so.
