Bricks are laid with a mortar joint bonding them together. The finished profile of the mortar joint is known as ‘pointing’, and can be varied depending on exposure or to create a specific visual effect.

When masonry structures are first constructed, mortar is applied as a thick paste which sets hard as it cures, creating a tight seal between bricks and blocks to prevent air and moisture entering into the construction. It can compensate for variations in brick or block size to produce an aesthetically-pleasing and structurally-sound construction.

Depending on the age of the building, the mortar used for pointing will be either lime mortar for houses built pre-1920s with solid walls; or cement mortar for houses built post-1920s with a cavity wall.

The most common pointing profiles are:

* Flush: The mortar is finished off flush with the edge of the masonry units.
* Recessed: Mortar is pressed back by 5 mm or more from the edges.
* Beaded: A more rounded type of pointing with a concave edge. It looks good but can damage easily.
* Struck: Similar to flush except the upper edge is pressed back inside the face by 10 mm.
* Rubbed: Also known as keyed or grooved, this is a rounded groove formed in the middle of the pointing using a suitable tool.
* V-pointing: Similar to rubbed but is a sharp inward V-groove rather than rounded.
* Weathered: This is a V-shaped projection from the face of the masonry unit.

Generally, mortar is structurally weaker than the blocks or bricks it bonds, creating a sacrificial layer that is more easily repaired than defects would be in the bricks or blocks themselves. As a result, mortar joints can decay over time, due to weathering, frost damage, and so on. When this happens, repointing is undertaken to renew them.
