Why Mortar Matters
You may be surprised to know that the mortar joint and colour can considerably alter the appearance of your bricks so it is important to plan your brick and mortar colours together. Mortar colour can be changed by adding tints or by using different coloured sand.
Your mortar can help achieve either a relaxed light feel or a dramatic contrasting effect. For example, a cream mortar with light coloured bricks to achieve harmony or bright white mortar in contrast to darker bricks for a more distinct look.
Common mortar colours include:
- Natural or grey- this was once the most commonly used mortar
- White or off-white- highlights the true colour of the brick
- Cream or buff- can tone in with lighter bricks
- Coloured mortar to match the brick colour- to reduce the distinction between brick colour and mortar

The mortar joint refers to how the band of mortar between the bricks is finished.
Raked joints are most commonly known, where the mortar is recessed from the brick face by about 10mm.
Rolled or Ironed joints complement nearly all brick and house styles and are increasingly popular for their clean, contemporary finish.
Flush joints provide a flatter look and will lighten the overall colour of the wall by minimising shadow.
Tip: Wherever exposure grade bricks are used, finish with an Ironed joint to minimise erosion from salt and make sure the correct grade of mortar is also used.
