Gorilla glue on back of treads.
Glue treads to stairs.
It was slow going until everything was cut, then install was pretty fast. I used nails on underside of treads since the glue didn’t always grab as well as I wanted.
Almost done.
One set down, one to go.
Added quarter round for looks.
I bought vinyl quarter round since it is easy to work with and didn’t need paint. I used a cheap little miter saw/box to cut quarter round to fit – this wasn’t necessary but I liked the finished look.
Voila.
