Laminated wood flooring is durable, easy to maintain and easy to install. The tongue-and-groove installation system common with laminated wood flooring makes installation easy. However, you can continue the look of your flooring on an adjacent staircase if you prefer, even though you don't install it with the tongue-and-groove installation system like you do on traditional floors. Install laminate stairs with the same power tools you used for the rest of the installation.
Measure the dimensions of your staircase, using a tape measure. When you look at your staircase, you'll notice two parts to each step--the horizontal plane where you walk, and a vertical piece that connects the steps to each other. Measure both the horizontal and the vertical pieces, because you want to cover both with flooring. Measure every step because each step's dimensions will likely vary slightly.
Cut your laminated wood flooring to size, using a circular saw and the dimensions from your staircase measurements.
Install a layer of thin foam padding on top of your staircase to help prevent your steps from creaking and to provide a soft barrier between your laminated wood stairs and the subfloor on which you installed the laminate.
Set the first flooring piece you cut on the step, and then hammer finish nails around the edge of the laminate flooring and through the subfloor. Continue this process until you lay each horizontal and vertical piece in place.
Measure the width of each step so you know how wide to cut your stair nose moulding. Stair nose moulding is a trim piece that covers the corners where your laminated wood flooring planks meet. Use your circular saw to cut the moulding pieces to the appropriate size, and then secure them in place with finish nails.
