This is where the argument against rising damp comes unstuck. On an

thats not a very satisfactory approach, and may or may not be adequate
but, if that doesn't work, what are you left with?
In 99% of cases, reducing RH to stop the condensation. In the last 1%,
salt contamination or rising damp.
And how do you reduce RH other than by heat and ventilation?
The usual start is to look at the sources of the damp. Showers, roof
leaks, boiling food at excessively high settings, all can be much
improved in many cases. Theres also dehumidifiers, which work out
cheaper than ventilation, though some vent is of course needed.
