What is Ceresit CT 49?

Ceresit CT 49 is a high-end Silicone Paint featuring advanced nanotechnology for a superior "Self-Clean" effect. It creates a high-tension, hydrophobic surface that is exceptionally resistant to dirt, UV radiation, and biological contamination. It is the professional choice for protecting External Wall Insulation (EWI) systems and revitalizing historic facades where maximum breathability and cleanliness are required.

  • How does the Ceresit CT 49 Self-Clean technology work?
    CT 49 uses nanotechnology to create a surface with extremely low wettability. Rainwater does not soak into the paint; instead, it forms droplets that roll off, picking up dust and pollutants. This "lotus effect" keeps the facade clean even in high-pollution urban environments.
  • Is CT 49 better for coastal properties?
    Yes. Due to its very low water absorption (W3) and high resistance to salts and UV, CT 49 is specifically recommended for coastal regions where salt spray and intense sun can degrade standard masonry paints.
  • Can CT 49 be used on Mineral Wool insulation?
    Absolutely. Because CT 49 has very high vapour permeability (V1), it is the perfect finishing coat for breathable Mineral Wool EWI systems, ensuring moisture can escape while the wall remains 100% waterproof from the outside.
  1. Cleaning: Wash the substrate to remove all organic growth and loose dust.
  2. Priming: Apply Ceresit CT 17 or CT 10 to stabilize the surface and ensure the Nano-resins bond correctly.
  3. Preparation: Stir the paint thoroughly. For the first coat on very porous surfaces, you may dilute with a maximum of 5% water.
  4. Application: Apply the first coat and allow it to dry for 4–6 hours.
  5. Final Coat: Apply the second coat undiluted. Ensure a "wet-on-wet" application on large walls to prevent visible joins. 
  • Pro-Tip for Dark Colors: CT 49 is highly recommended for dark facade colors. Its UV-resistant formula protects pigments from fading under intense sunlight, maintaining the "new-look" color for years longer than acrylic alternatives.
  • Pro-Tip for Urban Areas: In cities with high traffic, CT 49 prevents soot and smog from embedding into the paint texture, significantly extending the time required between building cleanings.
