Application of KEIM Silicate Paints on Fair-Faced Concrete
Providing ultimate protection and aesthetic recovery methods for old and fresh fair-faced concrete while preserving its original mineral structure.
Chemical Interaction & Heritage
KEIM silicate mineral paints have been commonly used in Northern Europe since 1878. Silicate paints penetrate the surface where applied and create a chemical interaction through inorganic colour pigments, sodium silicate, and mineral-based fillers. It becomes an integral part of the surface rather than a coat that merely covers it.
Natural Aesthetic Preservation
The surface retains a mineral matt appearance, just like natural concrete. Wooden mould trails are preserved, while forming a strong bond through the silicification process. Coats can be adjusted in transparency and color to balance differences with “Concrete grey” or create customized architectural finishes.
Key Advantages & Technical Features
UV Durability: The binder, Sodium Silicate, offers extreme resistance against UV light and atmospheric breakdown.
Vapor Permeability: High water vapor transmission with low Sd values (<0.02 m) allows concrete to dry rapidly.
No Swelling or Spalling: Inorganic mineral pigments remain unaffected by UV radiation and harsh weather conditions.
Absolute Colorfastness: Pure mineral pigments (Fb code B1) guarantee permanent, long-lasting color stability.
Moss & Mold Prevention: Fast surface drying and pure mineral composition eliminate organic growth.
Low Dirt Accumulation: Non-thermoplastic and anti-static properties ensure minimal soiling over time.
Eco-Friendly & Safe: Outstanding environmental profile—non-flammable and completely free of toxic odors.
Structural Protection: Forms an insoluble chemical bond protecting surfaces against weathering for decades.
130+ Years of Mineral Concrete Protection
The original concrete appearance is completely protected due to the mineral matt surface. With over 130 years of experience, KEIM offers complete products and solutions for concrete surface protection and fair-faced concrete applications.
