Solid oak treads on concrete stairs

Q: I have concrete stairs going to my basement. I want to glue solid oak treads and 1/4 inch plywood risers using Bostik glue.

What do you think?

A: I think you would still have to secure at least until the adhesive is set, otherwise, the wood may “wander”. A screw and plug on each side of the tread would work. I don’t know how you will deal with the 1/4″ ply.
