      Buildings must not just preserve the appearance and architecture …

      Besides optical demands our homes have to meet the requirements on the room climate and its associated level of comfort. A major contribution is made by the "outer shell" - protecting everything indoors from temperature or moisture.

      Particularly uncontrolled external moisture can not only disturb seriously the durability but also the room climate of a building. KEIM impregnations and water-repellent agents  make a key contribution far beyond aesthetic demands.

      Overview of KEIM IMPREGNATIONS & HYDROPHOBING AGENTS

      KEIM Silan-40-W

      Silane-based, hydrophobic, priming and impregnation agent in aqueous solution according to DIN EN 1504-2 with an active ingredient content of 40%. Water-repellent impregnation and primer for concrete and reinforced concrete in bridge construction, structural and civil engineering. and for alkaline substrates. Silan-40-W can be used as primer prior to coatings within the KEIM Concretal-System or only as water-repellent treatment.

      Colour shade

      Application
      Paint brush, flooding with a low-pressure gun

      Consumption
      0.2 – 0.3 kg/m2 (on concrete)

      Packaging
      25 kg container 
      Pallet: 6 x 25 kg

      KEIM Silan-C80

      Solvent-free, silane-based hydrophobing cream according to DIN EN 1504-2. Special product, particularly, for hydrophobing concrete in exterior spaces. Excellent penetration properties, optimal against the absorption of water and pollutants and also against frost and de-icing salt damages.

      Application
      Brush, flooding

      Consumption
      1 part concentrate + 9 parts of water approx. 0.2 - 0.8 l/m2 (ready-to-use mix)

      Packaging
      1 l container

      KEIM Silex?-OH

      Colourless consolidant based on silicic acid ester. For the use on any porous mineral substrate, particularly suitable for reconsolidating leached sandstone. Thanks to its excellent fluidity, KEIM Silex-OH penetrates deep into the pores of building materials. Good consolidation of the before friable building material without impairing the water vapour permeability by forming mineral gel.

      Colourless

      Application
      Brush, flooding (wet-on-wet)

      Consumption
      Approx. 0.5 to 5 l/m2, to be tested by trial area

      Packaging
      5 l containers
      Pallet: 14 x 25 l

      KEIM Silex?-OH-100

      Colourless, solvent-free silicate-based consolidant based on silicic acid ester. Can be used on any porous mineral substrate and is particularly suitable for reconsolidating leached sandstone areas. Thanks to its excellent fluidity, KEIM Silex-OH-100 penetrates deep into the pores of building materials. Deposition of the mineral gel effectively consolidates the previously crumbly building material without impairing water vapour permeability. (100% active substance content).

      KEIM Silan-100

      Solvent-free, silane-based water repellent to ZTV-ING OS-A. KEIM Silan-100 is used to provide a water repellent finish on exterior mineral building materials, in particular on concrete. KEIM Silan-100 may in particular be used where structures are exposed to freeze/thaw cycles with deicing salts and to protect reinforcing steel from chloride corrosion due to salt penetration and as a priming coat prior to subsequent applications of KEIM Concretal-W, KEIM Concretal-Lasur or KEIM Concretal-C as additional water-proofing when exposed to severe weathering stress.

      Colourless

      Application
      Brush, flooding with a low-pressure spray gun

      Consumption
      0.17 - 0.20 l/m2

      Packaging
      5 l and 25 l containers
      Pallet: 8 x 25 l / 78 x 5 l
