Salt-resistant, cement-free, breathable rendering mortar with semi-fluid consistency, easily workable by machine or trowel, based on lime and eco-pozzolan. Applied as a first coat under breathable and structural dehumidifying plasters, it improves adhesion, evens out substrate absorption and slows down the salt transfer process.

F.78 MUROSAN CALCE RINZAFFO must be used as a first layer, applied by machine straight onto clean masonry after the old plaster has been removed and before application of F.78 MUROSAN CALCE RISANA, in the following cases:
• Refurbishing masonry damaged by capillary rising damp in existing buildings, also of historic and artistic importance.
• Refurbishing masonry damaged by the crumbling and flakiness caused by saline concentrations.
• Reconstruction of old lime-based plaster damaged by the weather, environmental conditions and
wear and tear.
• Application of breathable and “structural” plaster coats when masonry is mechanically weak.
• Application of macro-porous dehumidifying plasters both indoors and outdoors on walls affected by
capillary rising damp.
• Repairing masonry damaged by efflorescences.
• Application of dehumidifying plasters to the masonry of structures situated in lagoon areas or near
the sea.
• Application of new dehumidifying plasters or refurbishing existing lime-based plasters in buildings of
historic and artistic interest (historic town centers, churches, manor houses, mansions) on masonry
made of stone, bricks, tuff and mixed materials.

For indoor and outdoor use.
