Examine the carpeted steps. The carpeting should reach up to the top stair riser. The stair nose molding will then cover the top edge of the carpeting.
Vacuum the top edge of the stair where the stair nosing will be installed.
Measure the width of the stair with a measuring tape. Transfer the measurement to the laminate stair nose molding with a pencil.
Cut the laminate stair nose molding to size on a miter saw. Check the stair nosing to see if it will fit in place on the stair. Trim as necessary.
Apply a 3-inch-wide snake-like bead of construction adhesive on the back of the laminate stair nose molding. Press the stair nosing in place on the step. The stair nosing should cover the top part of the carpeted stair riser and fit on the wood subfloor of the top step.
Pre-drill holes in the stair nosing with a drill and drill bit. The holes should be 3 inches apart.
Place finish nails in the pre-drilled holes, and hammer them down to anchor the laminate stair nosing in place. Use a nail set to set the nails below the surface of the laminate.
Install the laminate flooring out from the laminate stair nosing into the rest of the room.
