John,
So your saying that the use of the J - metal grounds, in conditions specifically against manufacture recommendations, is ok? Not to mention that I see the same thing in the photo Jerry pointed out, paper behind the screed plane, not over it.
If they can't even start the process right, what else lies behind, or above.
Failure to recommend further intrusive inspections to determine the total extent of the bad installation and what repairs are necessary for the client borders in irresponsibility at least. IMHO
