Water Repellent
Building facades play an important role in beautifying the structure and urban layout. On the other hand, the facade is a part of the building that is directly in contact with pollutants and weather factors such as rain, snow and sunlight.
Therefore, the building facade, over time, by absorbing a significant amount of pollution and moisture, gradually changes its appearance and is damaged. Today, Sahand Chemical facade water repellent product with a new formulation has made the work of protecting and maintaining the building facade easier. The water repellent product is a chemical and solvent-based material that, by reducing the penetration of water and moisture into water-absorbing surfaces, causes beauty and reduces erosion against moisture.
In this way, the building facade is protected against water and moisture penetration, and this issue will increase the life of the structure.
Sahand Chemical Facade Water Repellent
Sahand Chemical facade water repellent is a compound based on silane/siloxane and other additives.
The function of this product is that by applying it on the exterior surfaces of buildings, the contact angle of water with the facade surface increases, leading to a reduction in surface adhesion force and finally water repellency of the facade.
In general, this product can be applied on all kinds of porous and water-absorbing surfaces such as brick, cement, clay and adobe facades. One of the advantages of using Sahand Chemical facade water repellent is protecting the building facade by preventing water absorption and ultimately its erosion. By using this product, the building facade stays clean for a longer time and saves on facade washing and repair costs.
Sahand Chemical facade water repellent is a transparent liquid that, by increasing the contact angle of the surface with moisture, prevents the accumulation and remaining of water on the facade. Also, due to the colorless nature of this product, the appearance design and color of the facade remains unchanged after applying the facade water repellent.
t should be noted that the facade water repellent product cannot be used for interior walls. Also, this product cannot be used on glass or metal.
The reason is that the effectiveness of the Sahand Chemical facade water repellent product has a direct relationship with the surface’s absorption capacity. In other words, the more absorbent the surface on which this product is applied, the more water-repellent it will be.
Therefore, considering the nature of metal and glass and their lack of moisture absorption, the Sahand Chemical facade water repellent product will not be usable on these types of surfaces.
When the facade of a building absorbs water during rainfall, it suffers irreparable damage, so despite this problem, we should think about using a water repellent for building facades. It must be said that in large cities such as Tehran and Isfahan, air pollution is high, and the combination of this polluted air with water easily destroys the facade of a building.

Preventing dandruff, being washable, easy to implement, long lifespan, and preventing structural damage caused by moisture are among the benefits of nano-stone facade (hydrophobic facade).
Capillarity is a factor that helps porous surfaces absorb water. When a solid surface is wetted by water or any other liquid, the liquid increases its specific surface area and spreads over the solid surface. The surface energy of the solid acts to reduce the contact area and counteracts this increase in surface area. To do this, we need to cover the capillaries of the facade with a facade hydrophobic. Silicone and paraffin waxes used in facade hydrophobicity can do this.
Sahand Chemical Nano Stone Facade can be used to make stone facades made of travertine, granite, marble, and various types of artificial stones hydrophobic.
Before applying Sahand Chemical Nano Facade Coating, ensure that the surface under the work is clean of any dust and grease, and the surfaces must be completely dry. This product must be applied twice wet-on-wet by spray.
Yes. This product will waterproof the building’s brick materials by increasing the angle of contact of water with the surface and reducing the surface adhesion force, and will prevent water from entering the pores of the brickwork. By removing the water element, the brickwork will no longer sag.
