Pointing

Loosely speaking, 'pointing' is the mortar between bricks. A more accurate definition is that it is the visible edge of the mortar-joint. The mortar is normally a mix of lime and sand, or from the 1920s cement and sand. A colouring is sometimes added. Black mortar uses crushed ash rather than sand.

In Georgian, Victorian and Edwardian houses, the pointing between bricks and stone had a major effect on the appearance of the buildings. The emphasis was always supposed to be on the brickwork, rather than the pointing. The ideal was no visible mortar. This could be achieved by:

using high quality engineering bricks
'rubbed' brickwork, where the bricks were rubbed together until they fitted closely together, leaving a joint of 2-3mm
'tuck' pointing, where a line of white, putty mortar was 'tucked' into a slot cut in stained mortar
stained mortar to hide the pointing

Most houses used, at best, the last of these, with flush or slightly recessed pointing. Styles of pointing included flush, tuck, bucket handle and recessed pointing. Weatherstruck pointing was never used.

The two pictures below show an example of tuck pointing. You can see how the bricks are pointed with a stained mortar and then a line of putty mortar set in. The white putty is a mix of silver sand and lime.

These are examples of other mortar and brick combinations:

In some areas, the putty line is laid over the surface of the bricks:

In most cases tuck pointing was used to disguise poor quality, chipped and irregular bricks. This is why the line is on the surface - to suggest regular-sized bricks.

The stopping was 'wiped' over the bedding mortar while it was still 'green'.
