Description

Risanamur B-80 Evolution is the only natural all-lime-based plastering system that has proven its effectiveness through thousands of applications throughout Venice and Italy. During the past 30 years the plaster has been studied in depth and continuously refined to efficiently solve problems associated with capillary rising damp and – most importantly – of SOLUBLE SALTS contained within (chlorides, sulphates and nitrates).

It consists of two layers of lime plaster:

  1. RINZAFFO MGN: the inner layer, applied directly onto the masonry, is a hydraulic mortar with high adhesion power to wet surfaces that guarantees adhesion even to most difficult surfaces, consolidating the friable and degraded masonry. Its unique micro-pore structure with diffused porosity regulates the passage of vapours into the subsequent evaporation layer, while retaining the salts in a dissolved state inside the masonry.

  2. RISANAMUR B80, the outer layer, is an aerial lime and macro-porous hydraulic mortar that does not release salts. Thanks to its enormous evaporation surface containing a large number of free macro-pores, ensures the complete disposal of water vapors, filtered by the underlying Rinzaffo scratch coat, maintaining the surface of the plaster dry.
    For these reasons we recommend the application of at least 15 mm thick layer, and the use of highly breathable lime finishes.

Highlights

  • BREATHABLE: Exceptional performance in extracting and evaporating the moisture from the masonry, thanks to its special mix of air lime and NHL 3.5 natural hydraulic lime.
  • VERY LONG LASTING: Unparalleled performance and life span, even in the most extreme conditions and most aggressive environments, thanks to the mixture of natural pozzolans, enhanced since the Roman times for its characteristics.
  • GUARANTEED PERFORMANCE : With a unique dual an anti-salt barrier and consolidating function, certified to UNI EN998-2 standard.
  • PROVEN: Used on more than 1000 construction sites in the Ventian lagoons in extreme conditions of humidity and salt aggression.
