Remove plaster when installing new damp proof course?

Question: Why do you have to remove the existing plaster when installing a new damp proof course when the plaster looks in sound condition?

Answer:  Removal of the plaster in necessary as it is likely to contain ground salts such as chlorides and nitrates as a result of the rising damp. The salts are hygroscopic which  means that the have the ability to absorb moisture from the atmosphere so in times of high humidity the walls will continue to appear damp. Replacing the plaster removes this risk and re plastering with a special salt retardant system will prevent any residual salts in the brickwork from migrating into the finish coat plaster after the rising damp has been cured.
