Sanastof Bianco
Premixed mineral composition based on natural hydraulic lime NHL 3.5, microsilic with pozzolanic activity, selected aggregates, high tenacity microfibers, light heat-insulating aggregates with low modulus of elasticity. It is used for smoothing and smoothing, both indoors and outdoors. It is perfectly compatible with multiple substrates: lime-based plasters, lime-cement, cement mortars, concretes, porous stone, bricks. Its characteristics make it particularly suitable for green building works and for the restoration of period and monumental buildings. The maximum grain size of the aggregate is 0.9 mm.
Sanastof Bianco is a product based on natural hydraulic lime NHL 3.5, kaolin, marble dust, selected siliceous aggregates and light aggregates with a low modulus of elasticity, dimensionally stable. It is a natural product with high intrinsic breathability, without any trace of resins, solvents, diluents and radio-emissive aggregates. The product contains high tenacity microfibers which give great volumetric stability. The special rounded hollow aggregates, dimensionally stable, bring special qualities of thermal insulation, filtering of potentially harmful soluble salts and reduction of the elastic modulus to the shaving. The granulometric curve, the fineness of the binders and some rheological additives of natural origin, make the product particularly smooth during the drafting phase, even when laid on supports with rough or difficult surfaces. The calibrated physical-mechanical characteristics guarantee perfect compatibility on different types of substrates, especially on traditional plasters and mortars. The microsilic content with pozzolanic activity makes smoothing and smoothing performed with Sanastof Bianco highly durable, even in aggressive exposure environments.
Quick and easy application on various substrates, such as: transpiring smoothing of wall casings; smoothing on modular wood fiber or calcium silicate coats; regularization of plastered surfaces; leveling of concrete surfaces; regularization and smoothing of repairs carried out with cement mortars; application to mainly thin thicknesses (from 1 to 4 mm) with simultaneous leveling of recesses, imperfections etc. In particularly severe operating conditions it is advisable to interpose, between the first and second coat, the alkali-resistant glass fiber mesh Armaglass 160 (the mesh must be partially drowned on the first still fresh coat of Sanastof Bianco). The breathability, combined with the other physico-chemical characteristics of the product, make the smoothing made with Sanastof an ideal support to accommodate any kind of paint and in particular mineral paints based on potassium silicate or slaked lime. Sanastof is the transpiring smoothing, with a low modulus of elasticity, recommended in all our dehumidifying systems made with the products: Sanatigh, Caleosana, Sanawarme, Unisan, Intosana.
The application surfaces must be clean, free from dirt, crumbly and incoherent parts, dust, etc. Smooth substrates must be roughened (roughness> = 1mm). In the event that the support, after cleaning and roughening, is still dusty and crumbly, remove the totally incoherent parts dry with a spatula-brush, or assisting the removal operation with hydro-washing, then consolidate the support by impregnation with aqueous emulsion Protech Fix AC applied in two abundant coats, the second coat immediately before applying Sanastof Bianco with the "fresh on fresh" technique (the consumption of Protech Fix AC for this priming operation is between 120 and 250 gr / m2). Adequately wet the substrate with water before application, anticipating and repeating this operation several times in the case of very porous and absorbent substrates or in hot and arid climates.
Approximately 1,3 kg/m² of Sanastof Bianco for each millimetre of thickness to be implemented (on average 3 - 3,5 kg per square metre).
