Silimper Nano

20L, 3L, 1L
Silane-Siloxane nano-molecular impregnation compound

Description of the product

Silane-siloxane water-based nano-molecular impregnation compound, with high penetrating ability and hydrophobic
performance, ideal for applications on exterior and interior construction surfaces as a water-repellent

Fields of Application

Silimper® Nano is suitable for the impregnation of vertical (or inclined) mineral porous substrates, such as concrete, plasters and renderings, asbestos cement, brick, roof tiles, stone with continuous surface (i.e. without cracks), protecting from water absorption without changing the appearance of the surface.


  • Exhibits high penetration, due to its nano-molecular structure, minimizing the water uptake
  • Displays early repellence towards water, reacting chemically and bonding with the substrate
  • Prevents rain from impregnating the surface & protects it from cracking due to frost.
  • It is resistant to alkalis and prevents from efflorescence
  • Improves the heat insulating properties of the substrate, reducing the heat conductivity
  • Facilitates the cleaning of the surface by limiting dirt pick-up & fungal growth
  • Vapour permeable, allows the structure to “breathe”
  • Does not form a skin on the surface and does not alter its appearance
  • Does not change the original appearance of the surface
  • VOC-free - Contains no solvents
  • Certified with CE (EN 1504-2)
