Why lime plaster
never molds

When we talk about uncompromising mold protection, we rely not on marketing promises but on the fundamental chemistry of materials. The durability of high-quality lime plaster is rooted in its phenomenal alkalinity. In its freshly applied state and for a long time after drying, the surface maintains a pH of around 12 or 13. From a microbiological standpoint, this is a zone of absolute exclusion. Most pathogenic fungi and mold spores simply cannot survive in such an aggressive environment.

The second line of defense is the unique capillary structure. Unlike synthetic or cement-based compounds, proper mineral plaster has open pores. It acts as a powerful humidity buffer: when the room becomes too damp, the material instantly absorbs excess vapor, and when the air becomes drier — it releases it just as easily. Mold thrives on stagnant moisture and condensation, but on a lime wall, moisture doesn't linger on the surface — it distributes within the structure and evaporates.

It's important to understand one nuance. If years later you notice a dark spot on the wall — that doesn't mean the plaster has failed. Lime itself cannot mold, as it contains no organic matter. But mold can grow on what has settled on the wall from outside: kitchen grease, household dust particles. The plaster acts as a barrier — preventing fungus from penetrating deep into the wall.

Maintaining the protection in perfect condition requires minimal care: light dry cleaning with a soft brush or vacuum. Since the material is anti-static, it attracts far less dust than plastic or paint.

Following the application technology is the foundation of your confidence. Proper surface preparation, absence of hidden leaks, and use of only compatible mineral finishes create a system that remains biologically inert for decades.
