Stay tuned for a full breakdown of how to get rid of mould on walls permanently below.
What is Mould?
Before exploring how to get rid of mould on walls permanently, let’s first discuss its definition.
Mould refers to a type of fungus that thrives in damp, humid environments, typically found on various surfaces like walls, ceilings, and floors. It appears as fuzzy patches that can be black, green, or brown in colour, spreading quickly if not addressed promptly.
There are different types of mould, each with its own characteristics. Some moulds are powdery and fuzzy, while others may have a slimy texture.
The growth of mould is fuelled by moisture, making bathrooms, kitchens, and basements common areas for its appearance. Mould spores are airborne, easily spreading to other areas if proper cleaning and ventilation are not maintained. It is crucial to detect and eliminate mould as early as possible to prevent health hazards and property damage.
Why Does Mould Grow on Walls?
Mould growth on walls is primarily attributed to excess moisture and humidity levels, creating an ideal breeding ground for mould spores to settle and proliferate. Poor ventilation, water leaks, and high humidity can contribute to the development of mould on walls.
When walls are constantly exposed to damp conditions, whether from leaks, floods, or even high indoor humidity, it fosters the perfect environment for mould to flourish. The presence of water allows mould spores that are present in the air to attach and grow on the surfaces.
Inadequate ventilation exacerbates the issue by trapping the moisture within the walls, accelerating mould growth. This stagnant air becomes a haven for mould colonies to spread rapidly, causing structural damage and posing health risks to occupants.
The Main Causes of Mould Growth on Walls
The main causes of mould growth on walls include high humidity levels, water leaks, poor ventilation, and condensation build-up. These factors create a damp environment that fosters the growth of mould spores, leading to visible mould patches on the walls.
High humidity levels provide ample moisture for mould spores to thrive, especially in areas with poor airflow. When moisture from leaks or condensation accumulates, it seeps into the walls, creating a breeding ground for mould. Inadequate ventilation exacerbates the problem by trapping moist air indoors, encouraging mould growth.
The Health Risks of Mould on Walls
Figuring out how to remove mould from walls is not only an issue of aesthetics but also of health. This is because the presence of mould on walls can pose significant health risks to individuals, triggering allergies, respiratory problems and other health complications if exposed for long periods of time.
