MASONRY REPOINTING
The mortar used throughout the area to bond the brick is generally a soft composition of lime and sand. This mortar allows for the expansion and contraction of the brick during warm and cold months and joints are recessed behind the face of the brick. Masonry repointing shall always be of soft mortar composition, and hard or premixed mortars shall not be used. The use of hard mortars will not allow old brick to expand and contract and results in brick deterioration. See appendix for mortar recipe.
Appropriate mortar joints.
Most buildings in the East Row Historic District have concave or flush joints and repointing shall follow these profiles. Mortar shall not be applied to cover the face of bricks or obscure detailing.
Mortar joints should not cover the face of the brick as at left, but should be recessed.
