HYDROPHOBIC TREATMENT OF FACADES AND DECORATIVE ARCHITECTURAL ELEMENTS

Atmospheric condensation lowers the materials’ carrying force by washing off free lime and causing efflorescence. Hydrophobic treatment is meant to fight this.  

The most popular hydrophobic substances are silica-based.  In pores and on the surface of the treated material they make the finest monomolecular film, that is impossible to wash off; it’s water-repellent, but it let the air molecules get through, that is, this material “breathes”.

Besides fighting efflorescence, hydrophobic treatment gives the walls anti-bacterial and anti-mold effect and fights fungus. To the plus sides of hydrophobic treated surfaces you can add not just water repellence, but also high freeze-thaw and UV resistance.

When the foundation bed is treated with hydrophobics of deep penetration, later on the surface acquires water-repellent properties.

Marble façade treatment includes urethane polymeric water-repellent coating that prevents the surface extra soaking and reflects the light, which is essential for light marble surface to avoid getting yellow.

For fungi hazardous areas (gables, dip-slopes) “PromTechService” company offers using hydrophobics of higher antiseptic control that stop mold and fungus development and prevent their formation.
