After removing the bathroom tile floor and plywood underlayment, I replaced some damaged diagonal 1 X 6" boards with a section of 3/4" plywood. The problem is the 3/4" ply butts up slightly lower, 1/16" to 1/8", than the remaining 1 X 6" flooring. My question:

Is troweling thin set mortar or cement the best way to level the plywood to the diagonal 1 X 6" flooring? OR will the cement/thinset mortar weaken the plywood over time, requiring a different approach?

If you are puting down tile, you will probably need another layer of plywood and possibly backerboard(my preference)

Go to and calculate your deflection. You may have to play with the floor thickness to get a desirable number. You can get away with thinset between your new floor and the overlayment to prevent movement.
