Feelin' groovy Mr Leeke!
Very well said, I agree completely
Also, Py:
Remember that moisture wants/needs to get out and it will push off whatever is in its way. With winter coming (not as aggressive where you are but you still heat your houses right?) the moisture will move toward the warmer/dryer side so "if" the interior "fits the bill" then it may damage the plaster. I know up here near NYC our interiors are currently warmer and more humid than the exterior but as with many things, could be different down where you are! Especially with a tight finish coat and the soon to be applied paint or wall paper.
All the best!

Sorry, the husband cannot be saved. However, the husband may be able to
save the day.
> the question is at what % is the moisture acceptable
This is the wrong question. Better put:
How much water is left in the wall, and does it have a way out of the
wall that will not damage the gypsum plaster.
The moisture content can only be measured within the capability of
moisture meter and the person holding it. For example, with my
Electrophysics RF (radio frequency) meter, this is 5/8" of an inch from
the detecting panel on the back of the meter. This meter cannot possibly
tell how much moisture is deeper within the wall, and for that matter
does not even tell the moisture content, rather it tells the density,
which must be interpreted by the meter user.
>>the contractor(a pirate not pyrate) is in a hurry to finish and
wants to go
back with a gypsum plaster
as it dries fast and .....he can get out like a good pirate
<<
Of course, the perfect moisture meter is a full interior coating of
gypsum plaster. Once in place it is self monitoring and will tell you
exactly when and where there is too much moisture--it may take some time
to give you a reading.
Consider the Fast/Cheap/Good triangle, where you can have only two at a
time, but not all three at once. It appears the contractor is operating
in the Fast/things/Cheap miasma where Good work cannot happen. You (and
probably her building) are operating in the LowCost/people/Good realm,
when the slower you go, the closer the work is to Good. The contractor
and your wife can have the work Fast and Cheap, but it probably will not
be Good. Your wife is asking you to skate (on thin ice) back and forth
between the two realms, so what makes a better lubricant for your
skating, water in the wall, or rum in the gut. Water does make a very
excellent lubricant--when it is in the solid state. I suggest rum on
ice, for you, for your wife, and a double dose for the contractor. This
ought to slow the bunch of you down a bit to get a little closer to Good.
Slow down, you move to fast. You've got to make the moment last...
