Moisture, frost, de-icing salts and daily soiling wear down mineral surfaces year after year. The NP® Liquid Glass technology forms an ultra-thin, transparent SiO₂ layer that protects natural stone while the material continues to breathe.
Water and dirt are repelled while the material keeps breathing.
Moisture, dirt and de-icing salts penetrate mineral surfaces.
The NP® Liquid Glass technology creates an ultra-thin, transparent protective layer on mineral surfaces. Through targeted surface functionalisation, water- and dirt-repellent properties are achieved without altering the natural characteristics of the material.
The distinctive appearance, texture and structure of natural stone are preserved, while the surface is supported against moisture, contamination and weather-related stresses. A key advantage: the natural water vapour diffusion of mineral building materials is maintained. The material keeps “breathing” while the surface remains protected.
The performance of the NP® Liquid Glass technology has been evaluated by independent institutes and through material science investigations. The tests confirm the protective performance and the preservation of key material properties.
The nanopool surface technologies are suitable for a wide range of natural stone and mineral-based building materials. Tap a material for details:
Especially in sensitive natural stone applications, preserving the original material properties is essential. Tap an application area for typical use cases:
Public, commercial and industrial buildings exposed to weather all year round.
Façades take the full impact of rain, frost, de-icing salt spray and airborne dirt. The NP® layer supports long-term value preservation while the façade keeps its natural face.
Heritage conservation with tested material compatibility for sensitive substrates.
In heritage conservation, preserving the original material is essential. Studies confirm that the NP® protective layer acts close to the surface and respects the structure of the material.
Design surfaces, floors and walls in high-traffic environments.
High-quality stone interiors stay presentable with less cleaning effort. Appearance and feel of the material remain unchanged.
Concrete and exposed concrete in demanding outdoor conditions.
Outdoor structures face moisture, frost and de-icing salts. Reduced water absorption supports the durability of concrete and mineral surfaces in demanding environments.
Building owners, architects, project developers and property operators face the challenge of preserving high-quality materials over the long term while optimising operating costs and resource consumption. nanopool solutions create added value through longer maintenance and cleaning intervals, reduced water and chemical consumption, and long-term preservation of property value.
Designed for:
The most common questions from architects, planners and heritage specialists about protecting stone and mineral surfaces.
No. The transparent NP® protective layer preserves the natural appearance, texture and structure of the material.
Yes. Investigations confirm that the water vapour diffusion of mineral surfaces is not reduced by the NP® technology.
The protective performance has been tested and confirmed under freeze-thaw and de-icing salt conditions over 100 cycles.
Yes. Due to its tested material compatibility, the technology is particularly suitable for sensitive natural stone applications, architectural projects and heritage conservation.
Yes. By protecting valuable materials, extending service life and reducing cleaning requirements, the technology can contribute to sustainable building concepts.
