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. Covering building materials like tile and ceramics by hydrophobic coatings reduces water aggregation on their surface and keeps them clean by preventing forming dried water stains on them. Hence, using nanotechnology-based hydrophobic coatings on the ceramic surfaces has developed a keen interest for manufactures and consumers.
Applying nanoparticles on the various surfaces reduces their roughness surface energy and makes them hydrophobic as following table.
