|Sure Ways to Prevent and Cure Efflorescence|
A change on the surface to a powdery substance upon exposure to air, as a crystalline substance through loss of water.
To become encrusted or covered with crystals of salt or the like through evaporation or chemical change.
Sources and Causes of Efflorescence
Conditions for Efflorescence
- First: There must be water-soluble salts present somewhere in the wall
- Second: There must be sufficient moisture in the wall to render the salts into a solution
- Third: there must be a path for the soluble salts to migrate through to the surface where the moisture can evaporate, thus depositing the salts which can crystallize and cause efflorescence.
