The paper is specialized in the preparation of the coatings, both of Na 2O B 2O 3 SiO 2 inorganic system and of Na 2O B 2O 3 SiO 2 KH560 inorganic organic system, by Sol Gel method on the surface of cement mortar. The effect of modification of cement mortar is also discussed on the basis of the investigation of properties such as the rate of water absorption, weatherability, washing fastness, alkali resistance, acid resistance and superficial hardness, respectively. With the appropriate addition of KH560, especially when the ratio of KH560 to TEOS rangs from 0.25 to 1 (in mole), the formed inorganic organic coatings show better properties mentioned above, which result in the better durability of cement mortar.
