General Information
Definition
Silicone based concentrated impregnation and surface protection material, providing water impermeability without decreasing the water vapor permeability of the surface applied on without giving any color or sheen to it.
Usage Areas
Impregnation of porous mineral surfaces such as concrete, lime-sand stone, brick where waterproofing is required, Impregnation of surfaces coated with any kind of paint or plasters having relatively low water resistance, Priming of surfaces before the application of paints and plasters.
Package
  • 1 lt plastic bottles
Features
Penetrates into the substrate deeply. Does not change the color and the gloss of the surface. Forms a hydrophobic zone on the surface. Does not prevent the water vapor permeability of the surface applied on. Easy to apply with brush, roller or spray gun. Extremely durable; not affected by severe weather conditions like UV, rain and freezing.
