Tuckpointing can be defined as the removal and replacement of old crumbled mortar between bricks and stones. Tuckpointing is also known as repointing or just pointing. All three terms are often used interchangeably to describe the complete process of restoring older masonry joints.
The following definitions of these terms have been recommended by The Brick Institute of America:
Point - to place plastic mortar into joints to correct defects or to completely fill joints in newly laid masonry.
Repoint - to place plastic mortar into cut or raked joints to correct defective mortar joints in masonry.
Tuckpoint - (1) to point masonry with a flush mortar joint that approximates the colour of the masonry units and a mortar of contrasting colour that is shaped into a thin strip. (2) see repoint.
