This product is a nano colloidal liquid that is used to make hydrophobic stone surfaces. Applying nanoparticles on the various surfaces reduces their roughness surface energy and makes them hydrophobic as following table.
Water absorption by building materials is an important issue which reduces the mechanical and functional properties of the used material and consequently affects facade of the building. Stone is one of the most commonly used building materials with various applications in construction and building facades. Today, finding a method to prevent water from penetrating the stone is the one of main goal of the building materials companies in which nanotechnology is pioneer.
