Have you noticed unsightly white blooms cropping up on your walls, especially near windows or in damp spots? These unwelcome houseguests are what’s known as efflorescence, and they’re a common headache for homeowners across the UK.

Efflorescence has a lot to do with the moisture content in the material it develops on, so it’s natural to assume that condensation plays a role in its formation. However, the answer isn’t quite that simple.

With over five decades of experience, Prokil stands as the South’s go-to company for damp and condensation treatment. Below, we’ll dive into what efflorescence actually is, how condensation relates to it, and what you can do to keep it at bay.

What is efflorescence?

Efflorescence is the white, powdery substance that sometimes forms on concrete, brick, or stone. It occurs when water-soluble salts migrate to the surface and react with the air to form crystals. These salts are usually present in the building materials themselves or in the surrounding soil.

Efflorescence isn’t harmful to humans or structures on its own, but it can be a warning sign of underlying problems. It often indicates the presence of moisture in the material, which can lead to long-term issues like deterioration, mould growth, or structural damage. As a result, addressing efflorescence’s root cause is essential to prevent potential complications down the road.

What causes efflorescence?

Efflorescence is a common phenomenon in construction and can be caused by various factors, including:

• Water infiltration: Water moving through porous materials can dissolve salts and carry them to the surface. When the water evaporates, the salts are left behind, resulting in efflorescence.
• High humidity: Humid conditions can contribute to the migration of salts to the surface, especially in areas with poor ventilation.
• Improper curing of concrete: If concrete is not properly cured, it may not develop sufficient strength and may be more prone to efflorescence.

Does condensation cause efflorescence?

Not exactly, but it can contribute to the conditions that lead to efflorescence.

Condensation occurs when warm, moisture-laden air comes into contact with a cooler surface, causing the air to cool down and release its moisture in the form of water droplets. This commonly happens on windows, walls, and other surfaces in buildings.

When condensation occurs on a surface, it can provide the necessary moisture for the transport of salts within building materials. As the moisture moves through the material and reaches the surface, efflorescence may occur if the salts are present.

How do you prevent condensation from causing efflorescence?

The only way to stop condensation from contributing to efflorescence is to prevent condensation itself from forming. Luckily, there are plenty of ways you can do this:

• Good air circulation helps prevent moisture buildup, so improve ventilation in the affected area to reduce humidity levels. You can do this by opening windows and installing vents and extractor fans.
• If ventilation alone isn’t enough, consider installing dehumidifiers to reduce the overall humidity in enclosed spaces.
• Keep a consistent temperature throughout your home by insulating windows, walls, and ceilings. This prevents warm indoor air from meeting cold surfaces, reducing the chances of condensation.
• Place moisture-absorbing materials like silica gel or desiccants in areas prone to condensation, such as closets or storage spaces.
• If you’ve tried the steps above but still can’t seem to get rid of condensation, it might be time to bring in the experts. Specialists can use advanced equipment to survey your walls and flooring, pinpoint the root cause of the condensation, and carry out effective treatment measures.
