Should the back face of brick veneer be parged?
Brick veneer walls should be constructed with a free-draining cavity between the veneer and the backup wall. Parging the back of the veneer can contribute to mortar droppings at the bottom of the cavity that interfere with proper drainage. Parging also may hold more water inside the brick veneer, which could lead to deterioration. Parging the veneer is thus unnecessary. Norbert V.
