KEIM CONCRETAL-LASUR MINERAL PROTECTION
As one of the most fundamental cornerstones of structural engineering, concrete shapes projects of many different scales worldwide, from sports stadiums to museums, industrial buildings to residences. Guided by the slogan "Mineral-based protection for a mineral-based material", KEIM, with its 148 years of experience, holds a unique position in this field as the inventor of potassium silicate paints. The necessity of concrete remaining as concrete even on a protected surface is only possible through the use of materials of a similar nature, namely mineral architectural protection systems.
Unlike conventional coatings, KEIM mineral-based potassium silicate paints do not form a film layer on the surface to which they are applied. The combination of its binder, water glass (potassium silicate), with inorganic color pigments and mineral fillers, penetrates the surface and enters into a chemical reaction. As a result of this process, known as "silicification", the material becomes an inseparable part of the surface. Since it integrates into the cross-section, it does not peel, blister, or fade, ensuring the concrete is protected long-term against degradation caused by harsh weather conditions.
The most critical challenge on fair-faced concrete and fiber-reinforced concrete surfaces is to repair defects without altering the characteristic texture of the concrete. KEIM Concretal Lasur is a specialized product line that repairs concrete defects while preserving the concrete's character. Thanks to its natural, matte, and semi-transparent finish, the appearance of the concrete can be tailored to match the architectural design. Depending on the dilution ratio, the surface can be made more or less transparent; color variations can be balanced using "concrete grey" or an aesthetic finish can be achieved with fully colored silicate mineral paints.
SYSTEM ADVANTAGES
On fair-faced concrete surfaces with visual imperfections, it balances defects and provides aesthetic integrity without masking the unique natural texture of the concrete.
With its extremely low water vapor diffusion resistance, it allows the structure to breathe, ensuring that surfaces wet from rain or moisture dry out very quickly.
By chemically reacting (silicifying) and integrating with the substrate, it strengthens the concrete surface and creates a long-lasting protective shield against the harshest weather conditions without peeling or blistering.
Thanks to the pure inorganic mineral pigments it contains, it shows complete resistance to UV rays; classified under (Fb-Code A1) for absolute lightfastness, it retains its color even after many years.
Due to its non-thermoplastic and antistatic binder structure, the surface does not build up static charge, making it difficult for dirt to adhere and keeping the building clean for a long time.
It does not create an artificial, plastic film layer on the surface; thanks to its mineral matte texture, it preserves the original architectural aesthetic where "concrete remains concrete".
System Products

"Highlighting the natural beauty of concrete."
KEIM's mineral-based paints give surfaces an authentic, organic concrete look. Preserving the pure concrete aesthetic, the mineral matte texture ensures both outstanding aesthetics and long-lasting protection.
KEIM CONCRETAL-BASE
Specially developed for Concretal-Lasur applications, this is a sol-silicate-based and pigment-free dilution/additive component. Unlike simple dilution with water, it does not weaken the binder structure of the system when creating the semi-transparent (lasur) finishes targeted in architectural design. This maintains the paint's ideal application consistency and the thickness of the protective film on the surface. It holds Cradle to Cradle Certified® Silver and C2C Gold certifications.
