Capillary rise of groundwater, damage to plumbing systems, faulty gutters, leaking roofs, inadequate ventilation, and thermal bridges cause excessive moisture in homes or apartments.
On damp walls, roofs, or wooden elements, mold and fungi find favorable conditions for growth. Spores, organic compounds (MVOCs), and mycotoxins are released into the air, which can cause health problems.
Microwave technology helps combat mold infestation.

Environment conducive to growth
Regardless of the source of moisture, fungi and mold only require locally elevated humidity in the wall. Mold tends to remain mostly on the surface, while fungi can penetrate the material’s structure with their mycelium.
Once they colonize a damp area, they spread to neighboring surfaces. By absorbing moisture from the air, they create a microclimate favorable to their development, even when the substrate is drier. Within a relatively short time, they can cover a significant area.
The first and most important step in combating fungi and mold is to remove the causes of moisture.
Microwave Effectiveness
A common mistake is scraping off infected paint or remove plaster before fungi and mold have been eliminated.
During such work, active spores are released into the air, which are inhaled, settle on clothing and furniture, and can be transferred to other locations.
This can trigger allergic reactions, respiratory problems, and headaches, as reported in medical literature.
The first and most important step is to eliminate fungi and mold—i.e., deactivate spores and destroy the mycelium. One of the most effective methods is the use of microwaves.
Microwaves penetrate deeply into the wall structure, raising its temperature to 60–80 °C. This is achieved using Microwave Generators produced by MARKOM Microwaves.
This temperature is sufficient to destroy organisms present on the wall surface as well as mycelium hidden deep within its structure. The absence of biological activity limits health risks and eliminates the chance of transferring the problem to other areas.
Only after this stage is it possible to mechanically remove paint or plaster and carry out further renovation work.
Key Features of Microwave Technology
The use of appropriate equipment in combination with the properties of microwaves allows for:
- localized action, only in the area where the problem occurs,
- achieving high temperature throughout the entire cross-section of the wall, deactivating spores and destroying organisms on the surface and the mycelium inside the wall,
- high effectiveness in thick walls, where other methods and chemical agents fail,
- operation without the use of any chemical substances,
- drying of the wall within the area affected by microwaves,
- carrying out work without the need to evacuate residents.
