Is it OK to install laminate on stairs and how is it done ?
Yes you can install laminate to stair treads.
You can use a quality parquet floor or construction adhesive to secure the laminate down to the treads.
There will a need to also get a " nosing" to finish the edge of the treads. This will be fastened with a similar adhesive as above as well as a couple of screws.
