Pouring self-leveler on 2nd floor

I need to level my bathroom floor which already has the subfloor and
durock on. It's a good inch off. I've used the self-leveling stuff
from HD before, but never on the second floor, where if it leaks
through the floor, it's bad news. How would you recommend pouring the
liquid so that it levels the floor without finding its way beyond
through the floor surrounding the toilet waste drain, etc? I was
thinking of putting up the drywall and caulking the small gap between
wall and floor, then surrounding the toilet waste with some pieces of
wood and caulking that too. Once everything is caulked, I'll pour the
floor, let it setup, then kick the caulked temporary wood out of the
way. Any other suggestions? How do the pros do this?
Thanks!

Tape?? But won't the leveling material stick to the tape, not the
floor, thereby making it possible to crack or peel up? I mean, why go
through all that trouble of making absolutely certain it sticks to the
floor (clean, de-grease, primer, etc) only to use tape in the corners?
thanks for your suggestions!

I'd worry not about leaking but about the additional weight involved.

The weight is nothing... even four 50lb bags would be 200lbs. evenly
distributed across about 20sqft. Big deal? My 300lb father-in-law
will eventually sit on the toilet. Now THAT'S a big deal.

Point taken. What about that milky primer stuff? Needed, or
marketing jargon? I'm pouring over cement backerboard. Thanks!
