Firstly, Clean your stairs, remove all flooring materials and nails. If there is left glue, sand down the surfaces to make there are level and even. Remove If there are overhangs, Many stairs will have a pre-existing overhang: this is when the underside of the nosing on the upper steps is visible from the bottom of the staircase.
Treads and Risers
Measure up the vertical piece which goes on the front of the stairs and treads. Then cut your laminate flooring to size, letting the laminate flooring panel cover the whole area. Apply adhesive and nailing in the vertical piece which goes on the front of the stairs and treads.
Start at the top of the stairs. The easiest way to install your laminate flooring is to start at the top of the stairs and work your way down. By doing this, you avoid standing on the freshly installed flooring (and you won’t trap yourself upstairs when the job is done!)
Install the tread pieces. The threaded piece is the part of the stair that you actually step onto. To install the tread pieces, apply three beads of good quality wood glue to the subfloor, making sure not to put any on the space at the edge, which will be covered by the nosing later. Take the glued-together tread pieces you assembled earlier and place them firmly onto the tread, with the tongue edge of the plank facing outwards. If any glue squeezes onto the laminate planks, wipe it off quickly with a damp cloth.
For the laminate flooring, maybe you need to install a nose base before you lay the tread, but aluminum stair nosing should fit over the top and nailing, Holding its place. You must be double-checking all the measurements before you cut to make sure that everything will fit together nicely.
Once all of the laminate flooring areas are in place, you will need to file the exposed screw holes in the stair nosing with putty. Very important is to clean the stairs immediately, sweep sawdust, and peel off the tape from the stair.
