How thick should the new floor be? I can't imagine the changes needed to add
a 2" or 4" floor. All the doors, entrances, kitchen cabinets and plumbing
changes to be made. If there is a step at the entry doors, it may no longer
meet code. Ceilings will be "lower" now; windows will be "lower" now. What
do you do for closet doors? How about al the trim?

Do you really think this is a sensible method?

Installing baseboard heat requires none of the other changes needed here,
aside from some baseboard trim removal.

You can do it with about 1.5 inches of gypcrete

Same amount of changes, just a little shorter trimming. Not the way I'd go.

Yeah, but the OP was absolutely adamant that he
wasn't giving up in-floor radiant...
He'll have to weigh the pros and cons (if the Stop Leak
doesn't work :-)

Be very, very careful. Automotive coolant should never be used in a hydronic
system.
