Efflorescence Solutions

What is Efflorescence?

Efflorescence is a process that occurs when crystalline deposits of salts within the building material dissolve with the moisture and bubble up to the surface where the water evaporates leaving the powdery deposits intact on the surface. It can be seen where there is presence of humidity within or on brick, concrete, stone, stucco or other building surfaces. The eventual appearance is a whitish or greyish tint to the walls due to salt deposits that remain on the surface after water evaporates.

Reasons for Efflorescence:

There are three major types of efflorescence as shown below:

Primary efflorescence which occurs due to moisture captured by the material during the first installation of the structure. For example, it could occur at the application stage when the water used for a cement or mortar mix evaporates. In such cases, the problem may not recur if the surface is cleaned once the evaporation is complete.

Secondary efflorescence occurs when moisture is absorbed into a dry material, long after its installation. This can be seen during water infiltration from behind brick cladding, or water pooling in the ground beside or beneath a building. In these cases, the efflorescence remains until the problem is addressed. This can be rectified using corrective measures through Terraco Efflorescence Solutions.

Another reason efflorescence could occur in dry conditions is when water within a material evaporates before reaching the surface, which means the salt deposits occur underneath the surface. This can degrade the material resulting in scaling or spalling.

Can Efflorescence be left unchecked?

Aesthetically, efflorescence looks like a stained surface but could be indicative of excess moisture within the affected building material. This could be due to multitude of reasons and must be examined immediately to avoid any unpleasant surprises, such as unseen structural damage or mould formation.

To avoid these issues, Terraco recommends the below products that would be ideal to rectify efflorescence issues and ensure the structural integrity of the buildings.
