Efflorescence or formation of white powdery deposit on walls after painting is caused due to salts present in the building material like brick and mortar, which surface later on.

PreventionEdit

Give a long time gap between plastering and painting (about 6 months including one monsoon) Use paint with a porous film like emulsions and distempers.

CureEdit

Wipe off the deposited salts completely from the surface and ensure no more deposition before recoating.
