Danger from mold on the wall
An all-clear in advance: molds are not fundamentally dangerous to health. Finally, we are surrounded by their spores. Anyone who walks through the forest, for example, breathes in a lot of it. The danger depends rather on the mold type. Their concentration together. The individual state of health also plays a decisive role. Thus, people with an increased tendency to allergies, manifested asthma or hay fever are more affected by the infestation than others who are less allergic to it.
Mold on the wall – quick action is advisable
But this does not mean that "healthy" people should ignore the mold on the wall. Finally, all molds can cause allergic reactions. Anyone who lives in a damp and moldy apartment for a long period of time also has an increased risk of respiratory diseases and infections. Last but not least, most people find the sight of a mold infestation unsightly. A quick mold remediation is also advisable for this reason.
Possible reasons for mold infestation
Molds like it above all damply. If the conditions are optimal, they thrive within a very short time and are then visible as brown or black spots. If mold develops on the wall, it has many causes. Often it is a too high condensation or penetrating as well as rising wetness.
Condensation on the walls
Damp wall surfaces in particular provide the ideal breeding ground for mold growth. These can be caused by incorrect ventilation, improper heating or insufficient insulation. The construction method can also cause the walls to become damp in some places. New buildings, for example, are so airtight that air exchange by natural means is almost impossible. If there is no ventilation system installed, there is excessive humidity in the air, caused for example by showering, cooking, watering, etc. arises. The danger also exists in old buildings that have been renovated to make them more energy efficient. Controlled ventilation systems provide a remedy here.
Moisture due to penetrating wetness
Another possible reason for mold on the wall is penetrating moisture. This can occur in many ways: for example, as a result of a burst pipe or water damage. Defective roofs and cracks in the masonry are also frequent causes of moisture penetration.
Dampness due to rising damp
In addition to the danger of penetration from above, the moisture can also come from the ground. Experts refer to this as rising damp. If the horizontal barrier is faulty or defective, groundwater can soak the masonry and damage it in the long term. The persistent moisture in turn leads to mold on the wall.
By the way, to protect the home from standing water from the ground, homeowners can also install a drainage pipe.
Eliminate mold on the wall
If residents have discovered mold on the walls, they should react quickly – although differently. Those who live in rented accommodation should first contact the landlord and only then resort to removal measures. Homeowners, on the other hand, can start removing the mold immediately. Experts of the consumer center advise to divide the mold into new and old infestation.
Eliminate mold in case of new infestation
If the infestation is relatively new, the inhabitants can eliminate the mold on the wall with alcohol-containing agents from the pharmacy. With an alcohol content of up to 80 percent (ethanol), they can largely harmlessly remove mold from the wall. Chemical means are even faster and more effective. However, these should be used with the utmost caution because of their potential health hazards. In addition to gloves, it is also advisable to wear a mask.
Remove mold from old infestations
If a superficial treatment has brought no success, it may be because the mold has already penetrated into the paints or even existing plaster structure. Here house inhabitants should assign an expert with the removal. If necessary, waterproofing from the outside to prevent the penetration of moisture.
Preventive measures against mold
To avoid condensation on the walls, householders should pay attention to proper "heating and ventilation". Proper heating includes:
– Do not let the rooms cool down
– Take into account different room temperatures
– Do not cover radiators
– Shock ventilation and cross ventilation instead of tilt ventilation
– Use morning and evening hours
– keep bathrooms and kitchens dry
Likewise, centralized or decentralized residential ventilation can be used against mold.
