Mould on Walls: Is It Really Possible to Remove It Permanently?

Mould on walls is a common problem that can cause aesthetic damage and, in some cases, harm to health. It can appear on ceilings, on walls or even on the lower part of walls, because of damp rising from the floors. In any case, it is best to act quickly, before the problem gets worse and causes allergic reactions in those who live in the house.

Why does mould appear?

Mould is nothing more than a fungus that grows in damp, poorly ventilated environments and can appear on walls for various reasons. Excessive moisture, both in the air and in building materials, provides an ideal ground for its growth. A lack of ventilation prevents moisture from dispersing, creating favourable conditions for condensation and mould.

Inadequate insulation can cause condensation on cold surfaces, such as external walls, promoting fungal growth. Water leaks from broken pipes or damaged roofs can wet the walls, providing a damp environment that favours mould.

In addition, a lack of direct sunlight contributes to its growth, as mould tends to thrive in dark environments. Exposure to sunlight can therefore be a natural deterrent to its formation.

Other simple ways to prevent mould

From the causes of mould, you will certainly have grasped some simple tricks to prevent it or to stop existing damage from getting worse. Keeping home humidity at optimal levels, between 30% and 60%, is essential. This can be done by using dehumidifiers or by improving ventilation, regularly opening the windows to let fresh air circulate and installing fans in bathrooms and kitchens.

It is equally important to find and repair any water leaks that could cause dampness in the walls. Keeping surfaces clean with suitable detergents is essential to prevent mould. Remember not to wash floors with too much water, which could raise the humidity level in the home and create the perfect environment for mould.

Another permanent solution to avoid facing mould problems again is adequate thermal insulation, which helps prevent condensation forming on the walls, thus reducing the risk of mould. These preventive measures, if applied consistently, can help keep rooms free of mould in the long term.

But what if the room is already affected by mould?

Anti-mould treatments: what are they?

When do-it-yourself remedies prove ineffective against mould or the damage is really extensive, it is essential to turn to professionals for a thorough analysis and a targeted intervention to treat the mould. These experts carry out a careful inspection to assess the extent of the problem and identify the underlying causes. They then define an appropriate plan of action for removing the mould.

They may provide for chemical remediation, sandblasting or thermal fogging, depending on the extent and type of mould present. Once it has been removed, anti-mould treatments are applied to prevent it from coming back, such as primers and anti-mould paints.

What is anti-mould paint and how does it work?

Anti-mould paint is a type of paint specific to interiors that contains fungicidal and biocidal additives intended to inhibit the growth of mould and fungi on treated surfaces.

This paint works on two levels: first, it creates an environment hostile to the development of micro-organisms, preventing them from growing on the treated surface; second, if mould is present, the biocides kill the micro-organisms themselves, stopping them from spreading and helping to eliminate them.

However, it is essential to stress that anti-mould paint is not a definitive solution for preventing and treating mould. Its effectiveness depends on several factors, such as the severity of the problem and the underlying causes. If the mould is superficial and the causes of its appearance have been properly addressed, anti-mould paint may be enough to eliminate the problem and prevent it from returning. However, if the mould is deep-rooted or if the triggering causes are not addressed, the paint may not be effective on its own.

Choosing a high-quality anti-mould paint is crucial to ensure its effectiveness. Low-quality products may not offer the necessary protection against mould and may not stand the test of time.

C.W.C. Stop Condense by Diasen is our anti-mould thermal paint specifically designed for cold, poorly insulated interior surfaces. In addition to its anti-mould action, this paint offers extra thermal insulation that helps reduce condensation on the walls, thus improving living comfort.

Remember that, in addition to using an anti-mould paint, it is important to take other preventive measures, such as reducing humidity, improving ventilation and eliminating water seepage. By fighting mould on several fronts and adopting an integrated strategy, it is possible to create a healthy, mould-free environment inside buildings.

Conclusions

Eliminating mould for good requires constant commitment and a multi-pronged approach, but it is possible. In addition to new good habits for cleaning and ventilating rooms, you need to focus on adequate thermal insulation of the home: well-insulated walls and ceilings reduce the formation of condensation, a breeding ground for mould. Sometimes, mould problems are not linked to your habits but to the structure of the apartment block or villa. Contact your building manager or a mould treatment expert straight away if you notice this fungus appearing.

Diasen offers a complete range of eco-compatible, certified products to fight mould, including CWC anti-mould paint. This special paint, based on natural raw materials, not only eliminates mould that is already present but, thanks to its high breathability and lasting anti-mould power, prevents it from returning, creating a healthy and comfortable environment.

Diasen’s commitment goes beyond solving the mould problem: all products are formulated with selected, low-environmental-impact raw materials, respecting people’s health and the ecosystem.
