Seasoned slaked lime based finishing coating for interiors and exteriors.
VENETIAN PLASTER TONACHINO has a decorative appearance similar to that of plaster applied with a trowel or of smooth,colored marble. It is made up of seasoned slaked lime, natural pigments and oxides, selected Carrara marbles chippings and silica.
CHARACTERISTICS
VENETIAN PLASTER TONACHINO is a pre-coloured mineral plaster finish based on long-cured lime putty, mineral binder, select grain-size marble and silica dust, additives of vegetable origin, less than 3% organic binder (dry residue – - in order to give consistency and workability to the mix without compromising the characteristics of naturalness and breatheability. it is also composed of additives which foster ease of application and adhesion to the surface, and of mineral oxide and natural earth pigments.
VENETIAN PLASTER TONACHINO is ready to use, it is water vapour permeable, thereby maintaining dynamic the air diffusion in the surface, it is not subject to flaking and shrinking, resists alkaline aggression and abrasion, is non-flammable, does not “chalk” and gives the building onto which it is applied the warm and veiled tones typical of the colouring of antique plaster. Due to its particular mineral composition the product may be subject, in the case of exterior application, to irregular spotting and discolouration due to the uneven absorption of the product during the application phase, and over time due to exposure to various environmental factors; in addition exposure to persistent and driving rain in the first few days following application, especially if the rain is acidic, may give rise to the formation of a superficial whitish patina caused by a chemical reaction of the not yet carbonated calcium hydroxide, a phenomenon which tends then with time to disappear with subsequent rain showers. Such imperfections should not be considered defects but rather a characteristic of the product’s naturalness.
USES
VENETIAN PLASTER TONACHINO is perfect for the colouring and protection of buildings such as churches, palaces or villas or in any type of construction where a finish of elevated aesthetic value together with an excellent transpiration of the plaster is desired. VENETIAN PLASTER TONACHINO is applied to unpainted drawn “bastard mortar” (lime and cement) based plaster (in the course version), to civil plaster, to surface fillings executed with INTOCALCE. In the case of application to premixed plaster, dehumidifying plaster, mainly cement composition plaster, or surfaces with residues of previous organic type paints, the application of an intermediate coat of INTOCALCE is recommended in order to foster the chemical bond and durability.
