OTTO Siloxan 290L

The silicone for surface impregnation


  • Ready-to-use silicone surface impregnation
  • High penetration depth
  • UV-resistant
  • Can also be applied on moist substrates (not rain-wet)
  • Forms a water- and dirt-repelling surface
  • The hydrophobe effect prevents the penetration of moisture from the outside to the inside but it lets the internal moisture escape to the outside.
  • Bridges hair cracks up to a width of 0,3 mm
  • Reduces the tendency of treated surfaces to pick up dirt
  • Avoids humidity in the construction material thus avoids salt efflorescence as well as moss and algae growth
  • Paintable with commercial dispersion paints
  • Low odour
  • Colourless
  • Slight deepening of colour is possible

Fields of application

  • Hydrophobic treatment of façades and building components made of concrete, cellular concrete, fibre cement, brick-work, natural and artificial stone, mineralic plasters and coatings
  • Drainage of moist and cracked surfaces, which are then painted using dispersion paints
  • Only for vertical surfaces
