Cold nighttime air can cause condensation on walls and doors.

That moisture does something unexpected.

It reactivates the nicotine trapped beneath the paint.

In simple terms:

  • Moisture forms on the surface
  • Nicotine residue re-emulsifies
  • It seeps outward as sticky orange droplets

To the tenant, it looks like something new is appearing.
