Efflorescence

             Efflorescence




Have you seen white, powdery and dusty-looking deposits on your walls, especially around the corner edges of your home? Well, it’s time you acted on it! Why? Because, not all white things are pretty, what we are staring at is: Wall Efflorescence: a condition where salt (white) deposits are formed on the surface of the Walls.  The formation of salts is usually a result of excessive moisture in the tile. It is also known as Whiskers.

What is the cause of wall efflorescence?
The appearance of this white-coloured grouts or salt deposit happens when water enters the brickwork. The internally held salts dissolve in the water, while leaving its essential salts into masonry. So, what is left on the wall is the surplus from the base of the concrete. Basically, as the water evaporates from within the surface, the natural mineral in the water crystallises and becomes visible on the surface. Thus, if the walls are darker then efflorescence becomes more apparent.

What are the stages of wall efflorescence?
Efflorescence is a common occurrence, and it happens largely on more porous stones and sometimes even on tiles that aren’t on non-porous surfaces. The most common places, where you will notice efflorescence is around bathroom, driveway, and other areas that are likely to have high moisture. This happens in two stages:
One that happens instantly after usage is known as primarily efflorescence, and the other that happens at a later time – secondary efflorescence.

Impact of Efflorescence 
The good news is that this annoying built-up isn’t hazardous. This is just salt and can be easily removed. However, it is also an indication of excess moisture. So, it’s important to treat the moisture issue, which can cause deterioration if not treated in time. But, on the whole, efflorescence on the surface is mostly an aesthetic issue.

Treatment for Efflorescence
Sandblasting is one of the most popular and traditional ways of cleaning tile efflorescence. However, it’s harsh on the overall surface and removes everything in sight. Basically, the abrasive action of sand erodes the surface of the brick and the mortar joints along with salt deposits. This, in turn, makes the surface highly porous. Thus, it’s key to use sandblasting with caution, and follow it up with waterproofing.

The other option is to go with special chemical cleaners. Here, one must follow it up with a thorough cleaning of the surface with water to ensure that the floor is free of all cleaning agents, which could be acidic in nature.


The best course of treatment is ensured by blocking capillaries of porous building material and providing durable coating on the surface. Call 9711580095 / 836869715 Decor & Design
