The invention relates to a composition and to a process for cleaning and consolidating deteriorated decorative elements, such as stucco works and facade elements, while reconstructing the initial appearance of these elements. According to the invention, the composition comprises: a. a quantity of 1...4 g of titanium dioxide dissolved in 100 ml of water, 50...100 ml of hydroxyapatite as suspension type I, 1...4 g of phyllosilicate mineral clay as powder with the size ranging between 0.03...0.053 μm, stirred for 60 min, resulting in a consistent glossy white paste, b. a quantity of 1...4 g of TiO, 2.5 g of dried powder of hydroxyapatite ground in a mortar up to a granulation of 30...70 nm and admixed with 1...4 g of phyllosilicate clay as powders with a granulation of 0.03...0.053 μm, homogenized by stirring, after which it is added into 50...100 ml of distilled water while stirring at 300 rpm at the room temperature, until a paste is obtained. As claimed by the invention, the process consists in mechanically de-dusting the surface to be reconditioned, with a soft brush, under low ventilation, removing the wax deposits with the seaming tool, applying, with a brush or a putty knife, a layer of 0.2 mm, by two applications, followed by drying in air for 12 hours.
