Excess humidity: what to do when mold appears in your home?


Emma Potter

Mold stains in domestic environments are the most obvious manifestation of a humidity problem.

In dark and poorly ventilated rooms, the appearance of the characteristic black-brown speckled spots indicates that the invisible spores of the fungal microorganisms contained in the air have found an ideal habitat to proliferate.

From its first manifestation, mold can quickly colonize the entire environment, covering furniture and walls, as well as furnishings, upholstery and textile elements with its filamentous layer. Furthermore, in some cases, it also has the ability to secrete particular digestive enzymes, which attack the substrate that hosts it, causing its rapid degradation.

But if its spread in environments is extremely fast, eradicating it is a process that is anything but immediate, since it tends to reappear every time conditions favorable to its development arise again. To eliminate mold it is therefore necessary to act on the humidity, removing it definitively and preventing it from recurring.

What to do to eliminate mold on walls.

To eliminate mold from walls it is first necessary to say goodbye to do-it-yourself: manually erasing black stains on floors and walls, using bleach or specific anti-mold products, is a temporary solution, which in no way avoids its reappearance.

The only way to eradicate mold from walls is to resort to professional treatments, asking for the support of specialized companies who can combine a classic renovation intervention with a preliminary analysis aimed at formulating a definitive solution.

For example, proposals of this type include the solutions against mold in the home developed by Murprotec, a specialized company that has been researching, formulating and carrying out the best treatments to permanently eliminate humidity problems for over 60 years.

The professional interventions proposed by Murprotec are in fact based both on an advanced diagnostic phase and on cutting-edge intervention systems, an operational synergy that allows us to offer a tailor-made solution to the problem with guaranteed effectiveness.

Treatments that help eliminate mold from the walls of your home.

The execution of preliminary tests, aimed at identifying the origins of the humidity, allows us to act on the causes of the mold with targeted and decisive interventions. In fact, it is necessary to distinguish the humidity caused by condensation phenomena from that triggered by the rising of water in the walls by capillarity, as well as from the humidity that occurs due to an infiltration problem.

For example, in the case of buildings subject to infiltration of water from the ground onto the walls, the decisive treatment consists in the application of a two-component watertight coating in multiple alternating layers, which shields the external and house walls and completely eliminates humidity problems.

If mold and humidity on the walls are due to the capillary rise of water from the ground, through the cavities naturally present in the walls, it is possible to intervene by treating the walls with particular silicone emulsions, which, by infiltrating the pores of the building materials, create a barrier capable of shielding the rising water.

However, one of the most frequent causes of the appearance of mold on walls is linked to the humidity that forms as a result of condensation water: a phenomenon easily observable on windows, but less evident when it occurs on walls.

Condensation forms in particular when the walls are too cold and the quantity of vapor is too high, especially in those rooms exposed to the north-west or particularly difficult to ventilate. In these cases, the only way to permanently eliminate mold from the walls is to ensure that the walls remain dry, but above all, to prevent the spores naturally contained in the air from taking root and proliferating.

A professional intervention is based on the installation of a system for the exchange and regeneration of air, such as the Murprotec CTA: a centralized system which, due to the effect of overpressure, purifies the external air, heats it and injects it in environments 24 hours a day.

An AHU is a decisive solution as it eliminates fungal microorganisms responsible for the development of mold from the air and, by promoting perfect drying of the walls, ensures that humidity does not tend to reform.
