So for example, if a soft lime-based mortar was originally used, the most appropriate repointing mortar is likely to also contain a large amount of lime.

Tuckpointing was a way of achieving a similar effect using cheap, unrubbed bricks; these were laid in a mortar of a matching colour (initially red, but later, blue-black bricks and mortar were occasionally used) and a fine fillet of white material, usually pipe clay or putty, pushed into the joints before the mortar set.

In 1985, the Kaufmans sold the 2,000-acre (8.1 km 2) quarry to investors who filled in and developed the quarry for residential use, including Marble Cliff Commons [6] [2] [3] apartments and Marble Cliff Crossing, a 100 single-family and 60 double-family subdivision built between 1998 and 2003. [7]
It has been common since the widespread availability of Portland cement to see London stock brickwork repointed using much stronger cement mortar.

This joint is best used when the wall is intended to be plastered or joints are to be hidden under paint. Because the mortar is not compressed, it is less water-resistant than some of the other designs. Tuckpointing This joint has mortar colored to match the bricks surrounding a line of white mortar to make the joints look very small.
