Can You Mortar Over Old Mortar?
If your brick is 50 years old or less, you can probably repoint it safely with modern, portland cement–based mortar (although the guy doing the next repointing, who'll have to grind it out, may curse your decision).

Otherwise, over time, as the soft old brick swells and shrinks against the rock-hard mortar, the bond between them will break, moisture will get trapped in the wall, and the brick faces will start popping off. Traditional lime mortar acts like a cushion, flexing with the brick's movement while allowing moisture to migrate easily out of the wall.
