Multiple evidence points support the cause.
Treatment after the source
Damp wall treatment is not a paint name. It is whatever stops water entering that wall: weather coat on the rain face, wet-area work next door, or plinth detailing at the base. Interior emulsion is the last coat, not the first.
What you are seeing
How Gracia diagnoses
Which face is wet, after rain if possible. External map, plinth check, adjoining wet areas. Treatment is quoted on the source side. Anti-damp paint without that is a delay.
Nizampet rain-facing bedroom is the published case: crack fill and weather coat outside, not a third interior paint. Ground-floor Quthbullapur rooms add plinth damp to the same conversation.
Multiple evidence points support the cause.
Evidence indicates the cause; further verification may still be required.
One or more clues exist, but the evidence is not enough for a firm conclusion.
Inspected, and no supporting evidence found in the inspected area.

The one that matches the source. There is no single best paint. Rain-face, rising damp and bathroom feed are three different jobs.
