KS-G / Silicate primer for mineral surfaces

  • White silicate solution primer
  • For preparing concrete, lime, lime-cement plasters, bricks, blocks and other mineral surfaces before painting with silicate-based paints
  • Improves surface adhesion
  • Equalizes the absorbency of the surface
  • Ecological, environmentally friendly
  • Non-flammable
  • Completely matte
  • Maintains surface water vapor permeability (breathable)
  • Can be tinted in light shades


  • The primer can be used on unpainted mineral surfaces, as well as surfaces previously painted with lime, lime-cement, cement and silicate paints.
  • It is not recommended to use on surfaces previously painted with alkyd, acrylic, latex or silicone paints
  • Cover areas not intended for treatment (metallic surfaces, windows, etc.)
  • Apply as much primer as the surface can absorb
  • Complete surface planes should be covered in one pass so that no areas of primer coverage are formed
  • Do not paint in strong wind. Ambient air and surface temperature should be ≥+5°C, air relative humidity ≤80%
  • Prime fresh concrete surfaces no earlier than 2-4 weeks after construction work
