The white surface salts that disfigure new brickwork are derived from the mortar the bricklayer joined the bricks with. These salts are moved through the brick by capillary action. Sometimes, bricks are wetted before use to minimise this effect.
The efflorescence as it is known, will gradually disappear with weathering.
The addition of long-chain fattty acids (water extenders) to the mortar will help minimize the effect.

What happens to bricks in water?
When bricks are submerged in water, they can absorb moisture due to their porous nature, leading to increased weight and potential structural weakening over time. If the water freezes, the expansion can cause cracks or fractures in the brick. Prolonged exposure to water can also lead to efflorescence, where salts from the brick surface leach out, creating a white powdery residue. Ultimately, consistent water exposure can reduce the lifespan and integrity of bricks.
