Laying a hardwood floor involves preparing the subfloor, acclimating the wood, installing the first row, fitting the last rows and installing the trim. With the right tools, installing modern hardwood floors by yourself is an easy task, and this helps to reduce the overall cost.
The subfloor must be wood since hardwood floors cannot be installed on concrete. You can use plywood, an existing wood floor or tongue-and-groove solid wood as a subfloor. Before the installation, ensure the wood flooring is within the recommended range of moisture content with the subfloor. Mark the walls to show the joists, and install the first row perpendicular to the wall to ensure strength.
Drill holes adjacent to the joists to prevent splitting face-nailed boards. Countersink the nail holes with a nail punch, and fill the holes with a putty. Fasten the first row before installing the other rows. Spread the bundles of wood across the room, and make sure they are offset across the floor. Install the second row by tapping the boards together using a mallet. Drill pilot holes in the tongue, and nail the board. Install the rest of the boards one at a time, leaving an 18.5-millimeters expansion gap between the end board and the wall.
Ensure all the boards are straight, and frame any flooring obstructions, such as a fireplace. Cut all corners to fit the wall where there are jogs or obstacles. Cut the last row to fit the wall if necessary. Install the trim, and inspect the floor.
