SPRIZZO ANTISALE is a Biocompatible repair and restoration mortar pre-packaged powder for internal and external use according to UNI EN 998-1. SPRIZZO ANTISALE is totally free of cement and compounds belonging to the clinker group and is made up of a mixture of pure limestone sands, screened with a continuous granulometric arc from 0 to 2.5 mm, and natural putty regulators of the final porosity. The only present binder is the ST ASTIER Pure Natural Hydraulic Lime NHL 5 according to standard UNI EN 459-1. The lime NHL 5, white, is produced by baking siliceous limestones at temperatures below 1250°C and reduced in powder by calcium oxide only, without the addition of pozzolanic materials or hydraulic binders of any kind.
SPRIZZO ANTISALE is a Biocompatible Mortar, pre-packaged as a preliminary rendering for all surfaces with rising damp that require an absorption regulator layer. It is also capable of performing a blocking action against the appearance of soot spots on the masonry and enhances the vaporization capacity of the wall without causing damage due to the presence of dissolved salts and water vapour pressure. To fulfil these functions, SPRIZZO ANTISALE has unbeatable adhesion characteristics and maintains high breathability thanks to the content of natural putties.
