SPRIZZO Ponte di adesione is a Biocompatible repair and restoration mortar, pre-packaged powder for internal and external use according to UNI EN 998-1. SPRIZZO is totally free of cement and compounds belonging to the clinker group and consists of a mixture of pure limestone sands, screened with continuous granulometric arc from 0 to 2.5 mm, and higher quality compounds which improve adesione properties to the substrate. The only present mineral binder is 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 only the break down of calcium oxide, without the addition of pozzolanic materials or hydraulic binders of any kind.
SPRIZZO Ponte di adesione is a biocompatible mortar, pre-packaged, used as a preliminary rendering on all those compact or poorly absorbent surfaces which require an adhesive layer for the laying of the actual plaster. It is also used on those subbases which require a levelling layer to overcome small physical discontinuities. To fulfil these functions, SPRIZZO Ponte di ADESIONE has unbeatable characteristics of adhesion and consists of aggregate with coarse granulometry with few fine elements to ensure the easy obtaining of a rough surface which will act as adhesion layer.
