Efflorescence is a common phenomenon in masonry and concrete structures where soluble salts migrate to the surface, leaving behind unsightly white, powdery deposits once water evaporates. This happens when moisture within the material dissolves salts and carries them outward through capillary action. When the water reaches the surface and evaporates, the salts crystallise, forming the familiar chalky residue.

What Causes Efflorescence?

Efflorescence occurs when:

  • Water enters concrete or masonry surfaces.
  • The water dissolves natural salts present inside the material.
  • Moisture moves to the surface through pores.
  • Water evaporates, leaving behind white salt deposits.

This process is more common in:

  • New constructions
  • Areas with high humidity or rainfall
  • Poor waterproofing conditions

How Efflorescence Affects Buildings?

Efflorescence impacts both appearance and durability:

  • Makes walls look old, dirty, and poorly maintained.
  • Reduces the visual appeal of façades and interiors.
  • Causes paint peeling and poor coating adhesion.
  • Indicates ongoing moisture issues.
  • Over time, continuous moisture can weaken surface strength and finishes. Ignoring efflorescence often leads to bigger repair and maintenance costs.
