Yeah, I work with my dad. Our house right now has hardwood pretty much throughout with tiles in the kitchen and bathrooms. We have both on-site finish and pre-finished hardwood.

If you have any questions, just PM me. I don't want to get in trouble on here for promoting business.

I have had people ask me to do it this way, because they were too cheap to fork out a bit more to get a new subfloor installed. Do it right the first time is what I always tell people, but most of them don't listen.

Actually, k3 isn't a no no if you prep the K3 properly AND use hardwood floor nails that are long enough to catch the plywood or OSB that is under the K3.

I would re-nail the K3 down to the sheathing with ring nails and fill any joint and/or imperfections with thin-set concrete.
