Areas of application

Breathable plaster for load-bearing and infill masonry, for exterior and interior use, on hollow and solid brick, tuff, stone, and mixed masonry before applying Biocalce® plasters.

Biocalce® Rinzaffo is particularly suitable for leveling base plaster and adhesion enhancement in Edilizia del Benessere®, where the strictly natural origin of its components ensures the essential parameters of prescribed porosity, hygroscopicity, and breathability.

Biocalce® Rinzaffo is suitable for increasing the adhesion of Biocalce breathable plasters to stone, river pebble substrates, worn substrates in monument restoration, where the consciously dosed traditional components, such as natural lime, natural pozzolan, stone, marble, and granite, ensure a conservation intervention that respects the existing structures and original materials.
