Is your building's water tank making your water dirty?

Why does damp keep coming back after you repaint?
Because paint covers the stain, not the water. Damp comes back until the source is fixed: usually the roof or parapet, a leaking pipe inside the wall, moisture rising from the ground, or rooms that can't breathe. Find the source first, fix it, then repaint, and do it before the monsoon.
