Pergo is a type of wood laminate flooring. Wood laminate flooring is viable for installing on stairs, as well as flat surfaces throughout the home. Installation instructions for Pergo flooring, in general, applies to stair installation as well. The primary difference for stair installation is that you install stair nosing around the edge of the stairs to give it a finished look.
Place the unopened Pergo wood laminate boxes near the stairs where the floor installation will take place. The wood laminate must acclimate to the room. Allow the unopened boxes to sit in the area for at least 48 hours; however, Pergo recommends you allow the flooring to sit for 96 hours in humid or hot climates.
Place one to two planks of Pergo flooring on the stairs. According to Pergo, one plank of wood laminate covers most stairs. In some situations, it may take two planks. Lay the planks so that the wood plank or planks cover the width of the stair from right to left. This is a fit test to see if you need one or two planks to fit the stairs. Remember that the wood plank does need to come over the edge of the stair, because the stair nose finish covers two and three-eighths of an inch over the front edge of the stair.
Apply glue to the stair and the plank. Remove the one to two planks that you dry fitted. Apply glue to the stair and to the bottom of the Pergo wood floor plank or planks, using a paintbrush.
Repeat Steps 1 and 2 for each stair.
Measure a strip of stair nosing. Place the stair nosing on a flat surface. Measure the width of the stair where you are applying the stair nosing. Measure the stair nosing to fit the width of the stair.
Cut the stair nosing to fit the measurement you need for the stair.
Apply the stair nosing. Paint the construction adhesive to the bottom of the stair nose and adhere it to the front of the step so that it covers the front lip of the stair and the edge of the plank on the stair.
Add two screws. Use one #6 screw on the right side of the stair nosing to secure the nosing to the stair. Add a screw to the left side of the nosing, as well. You can add additional screws for wider stair nosing, but keep screw at eight inch intervals.
Repeat Steps 5 through 8 to add stair nosing to each stair.
Pergo suggests that you follow the instructions that come with the wood laminate flooring. If you want to finish the sides of the stairs, or the portions that meet the wall or the railing, you can apply stair nosing on the sides of the stair, as well. Since stairs differ in style, you may or may not need to add stair nosing along the top sides of each stair.
