In general

Alcohol dispersion of organosilicon compounds to water-oil repulse and protect mineral building surfaces.
It maintains the original appearance of the surface, preventing the entry of water and oily substances.


Indented Use

The product is suitable for:

  • Cement Products,
  • Stamped & industrial flooring,
  • Stone (natural or artificial),
  • Concrete pavings,
  • Cobblestones - curbstones,
  • Concrete & Plaster.

  • Appearance:       Transparent
  • Odour:               Ethyl Alcohol(alcohol)
  • Density:             Approx. 0.8 kg / lt.



On average 250 ml  per square meter (m2) depending on the porosity and the kind of the substrate.



Available in packages of 10lt.


Shelf life and storage

Since the product is not exposed to direct sunlight and it is stored at temperatures between 5 and 35 degrees Celsius, it can be retained in its unopened packaging for 12 months since the production date.


  • The surfaces to be treated must be clean from dust, grease and various residues. So carefully cleaning and sanding, when necessary, is recommended, while removing debris. The surface must be dry before applying the product.
  • The most appropriate method of application on large surfaces is spraying with High Volume Low-Pressure equipment (HVLP).  However, conventional methods such as roller, spray or dipping can be used. It is very important that the equipment is clean and dry without any residual material from a previous use. The final result does not differ in relation to the method of application, but in case of mechanical spray gun, there are savings on material and time as well.
  • In the first application, you must use enough quantity until the surface looks wet. In the repeat application (optional), which can be applied after the first application is dried, the quantity used is significantly less.
  • It is recommended to do a small test patch prior to application (e.g. in a corner) to check the behavior of the material.
  • The application should be made at room temperature, between 5 and 40 degrees Celsius


  • Possible change in appearance and texture of the surface will be negligible. A slightly darker shade in the surfaces after treatment may occurs.
  • Water vapour permeability is maintained. This means that the ability of the original surface to transpire is not affected. Thus, the potential trapped moisture is not prevented from exiting.
  • Since the coatings are resistant to UV radiation, their function is guaranteed for long periods, up to 5 years or more
  • Capillaries up to 0.3 mm can be sealed with the application of the product. Larger cracks, should be treated with conventional methods before applying the product.
