I’m putting a 3/4″ layer of plywood underlayment over my subfloor, then I’ll be putting down a hardwood floor.
Do I put rosin paper between the subfloor and underlayment, between the underlayment and wood floor, or both?
I’ve had people suggest to me that I shouldn’t glue the underlayment to the subfloor, because if I ever want to remove the floor, it’ll be a pain. Will I have any problems if I don’t glue?
And… I’m also going to be putting down a ceramic tile floor that butts up against the wood, and I’m trying to get the floors to be at the same height. I’ve got about 3/8″ thick, I’m putting a second layer of plywood subfloor under the ceramic that’s about 3/8″ thick, and I’m putting down mastic that’s got some thickness to it. Any tips on how to end up with floors that are the same height?

I'd screw the plywood down good and put the paper between the plywood and hardwood.
Getting tile and hardwood to match I've found that most of the time thinset + 1/4" Hardibacker + thinset + floor tile most often comes so close it looks like it was planned.
Glue and screw the plywood down.
Why would you want to remove it?
Use thinset for the tile and build it up as required to match hardwood.

That's what I would have thought, but I'm in the middle of taking up the second section of underlayment since I've been in this house.
What does gluing the underlayment do for you above just screwing it down?
Glueing it, with a construction adhesive, joins the two layers, making them one. Much more solid substrate.

If we considered "...what if I want to take it apart...." in everything we do, we would frame our homes with screws.
Glue it and screw it.
