How about the installation of stair nose floor molding?

The staircase level surface and facade should be 90 degrees, first of all, clean up the staircase steps, in the front of the staircase edge corner and the back of the stair nose floor molding,coated with adhesive and knocked it with rubber hammer when the corner and the stair nose floor molding bonded together after a while later. Or you could punch holes in the aluminum alloy base, fix the stair nose floor molding on the staircase surface with screws, and then inserted plastic strips on the surface of stair nose floor molding.
