How to Install Nailed-Down Hardwood Floors
- 1). Lay rows of rosin paper over the subfloor, in strips, overlapping the edges slightly. Shoot staples every 2 feet to secure it, using an electric stapler.
- 2). Lay a chalk snap line for the floorboards along the longest unobstructed wall in the room, sitting 1/2 inch out from it.
- 3). Lay a floorboard on one end of the line, so the grooved side is facing the wall and sitting 1/2 inch out from it. Secure it with a power floor nailer. Shoot the nails every 10 to 12 inches along both edges of the board.
- 4). Connect a second board off the end of the first, by its tongue-and-groove fittings. Lay the rest of the first course along the line. Nail each board down as before. Cut the final board on a miter saw to fit.
- 5). Press the next row of boards alongside the first, linking them by their milling at the sides. Shoot in nails through the sides, every 10 or 12 inches, so the nail heads are hidden by the next course of boards.
- 6). Continue laying the boards in courses, working your way across the floor. Lay the varied sizes of the boards so the ends are staggered between courses.
- 7). Length-cut the final course of boards to fit along the last wall with a ½-inch space there, using a table saw. Floor trim will cover the spaces.
