You never told us what you did to solve the damp problem. If
rerendering was it, it may or may not dry out, its not really a good
solution to damp.


It's often the only solution short of re-building the house. If water is
prevented from entering the wall from the outside, why wouldn't the
inside dry out?


Because moisture also comes from inside and below?

Lime lovers seem to have the idea that human activity generates buckets
of water that are prevented from evaporating by cement and/or a coat of
Dulux on the outside of the house. With normal heating and ventilation
this source of moisture shouldn't be an issue. If water is entering from
below then you need to stop it rather than accommodating damp as a way
of life. It really isn't very healthy
