Just moved into a new (well, new to me, house). First floor is all tile and
hardwood (oak). Second floor is all hideous teal carpet (all the rage 10
years ago, I guess). We have ordered all new carpets, but SWMBO wants me to
change the stairs to oak treads and white painted risers. The stairs are
still carpeted, so I am not positive, but I think they are make out of OSB.

My idea is to make a cap for each stair out of 1/4" plywood with a solid
edge. I have a few questions:

-What type of plywood should I use? Just BORG oak face or is there a better
grade out there that I should find?

-How should I adhere the tread to the stairs so it remains adhered when I
want it to, but I can remove and replace if it is damaged? Titebond II?
Hide Glue? Nails? or some type of Mastic?

I know I could replace the entire tread, but I am hoping to do this job with
minimal effort.

Thanks in advance
