Treating Efflorescence On internal Walls

treating-efflorescence-on-internal-walls1.jpg

It seems that no matter how long you spend decorating your home and no matter how perfect the finished look is, there is always something lurking in the shadows to destroy all your hard work. One such problem is efflorescence. 

Efflorescence sounds like something from a sci-fi film, but it’s actually found a lot closer to home. The term ‘efflorescence’ refers to salt residue that is left behind after water has evaporated.  

All you need for a bout of efflorescence to affect your home is water and salt, two components that are not too difficult to come across in most properties. You’ll find salt in the materials used to construct your home, and water, well, that’s all over your property and in the air.

When water that seeps through your walls picks up salt on the way, or when there is already salt on the surface of your walls, as soon as the water dissolves the salt and evaporates, hey presto, you have efflorescence. 

Thankfully, treating efflorescence on internal walls is not too difficult, but first, you need to make sure that you’re able to easily identify the problem...

On exterior walls you may notice a light dusting of the salt, and on interior walls, efflorescence can actually start to damage your paintwork

How Can You Identify Efflorescence?

Efflorescence is normally white or a very light grey and looks powdery. Generally, efflorescence is not very subtle, but if it occurs in a sealed area, it may be a little harder to spot. 

On exterior walls you may notice a light dusting of the salt, and on interior walls, efflorescence can actually start to damage your paintwork. 

The appearance of efflorescence is not a sure sign of structural damage, but it does mean that a lot more water is getting into your exterior walls that what is necessarily good for them.

Efflorescence may not destroy your home, but damp can have some pretty severe consequences.

3 Top Tips for Treating Efflorescence

If you’re struggling to deal with efflorescence on interior walls, then our top tips are here to help. We’ll walk you through how to get rid of efflorescence in the short-term and how to get rid of the problem for good.

Top Tip One: Clean the Walls with a Stiff Brush 

Unlike most visual contaminants on interior walls, it’s not wise to treat efflorescence with water, as that can only make the problem worse.

To rid your walls of efflorescence, uses a stiff brush to remove the salt from the wall completely. 

Top Tip Two: Repair Damage on the Exterior of the Wall 

Efflorescence is going to be a major problem if your walls are in poor repair. Cracks and gaps in your walls are just easy entry points for water, which will cause an efflorescence problem that brushing is not going to solve. 

Take a good look at your exterior walls and assess their condition for signs of cracks or damage. Enlist some professional help to get these problem areas repaired as quickly as possible. 

Top Tip Three: Apply a Hydrophobic Wall Coating to Exterior Walls

For a long-term solution, you need to make your exterior walls less prone to moisture absorption, which in turn, will mean that less water is able to pass through your walls, gather salt, and cause efflorescence to appear. 

A hydrophobic wall coating is one of your best options for lowering the water absorption of your walls, as the coating is specifically designed to repel water away from a surface. A high-quality hydrophobic wall coating will reduce moisture absorption by around 95%. 

The bond that the coating will create with your masonry will be about 17mm deep, which is more than enough to stop a significant amount of water entering your exterior walls.

The coating also retains wall breathability, so moisture from inside your home will easily be able to get out, and your risk of damp will be reduced.
