What is "tuckpointing"

Tuckpointing is a way of using two contrasting colours of mortar in the mortar joints of brickwork, one colour matching the bricks themselves, to give an artificial impression that very fine joints have been made. In some parts of the United States and Canada, some confusion may result as the term is often used interchangeably with "pointing" (to correct defects or finish off joints in newly laid masonry) and " repointing" (to place wet mortar into cut or raked joints to repair weathered joints in old masonry).
