Measure the stair where the laminate nosing will be installed with a measuring tape. Write down the measurement.
Transfer the measurements to the laminate stair nosing. Cut the stair nosing to size on a miter saw.
Apply two ¼-inch beads of construction adhesive on the back portion of the laminate stair nosing. Set the stair nosing in place on the stair. The nosing should cover the front portion of the stair, overlapping the riser.
Install the laminate flooring from the stair nosing out to the rest of the room. Follow the manufacturer's directions to install the flooring.
Tape the stair nosing to the laminate flooring while the glue beneath the stair riser dries overnight.
