I have two sections of flooring that are currently uneven by about 1/4". One side is 3/4" OSB, and the other is 3/4" Plywood. Both sides are screwed and glued onto joists. I'm planning on putting cement board across both sides to prep for tile after that.
- Should I use 1/4" Plywood to bring the two sides to level? Is there something else to use instead – like self-leveling compound?
- Do I screw the plywood into the joists or just into the underlying subfloor? Screw every 6 inches – or more or less?
- Do I use glue between the plywood and the OSB? Or something else between the layers?

I would use 1/4inch Luan panels and install without adhesive. Just install to manufacturers specs. This is typically to lay it down and use 1/4 inch crown staples, 1 inch long, every 6 inches along the perimeter and 8 inches in the field.
