Nanosil is a solvent-free high reactive Silicone based penetrating waterproof agent. Nanosil is developed to provide water repellency to porous construction materials such as cement blocks, mortar, plaster, painted surfaces and grouts as it penetrates deep into the surface voids and forms bonds in the voids.

This unique formula incorporates leading molecular nanotechnology; putting an end to water and moisture migration through any porous cementitious substrate.

The treated surfaces will show no change in visual appearance from application and the surface that will not chip, flake, delaminate or breakdown with UV light exposure

Typical Coverage Rates:

Indicative Coverage is in square feet per Liter for Porous Surfaces: 25–75 SF, Semi-Porous Surfaces: 75–150 SF, Non-Porous Surfaces: 150–250 SF

    Key Benefits
  • •  Effective protection even in driving rain
  • •  UV Resistant
  • •  Does not change the appearance of the base substrate or coating
  • •  Alkali resistance
  • •  A reduction in heat conductivity and thus improved thermal insulation
  • •  In most instances no change in surface appearance and virtually no reduction of vapor permeability
  • •  Solvent-free and low VOC
