Areas of use

Breathable plaster for load-bearing and infill masonry, indoors and outdoors, for hollow and solid brick, tuff, stone and mixed masonry before applying Biocalce® plasters.

Biocalce® Rinzaffo is particularly suitable for leveling base plastering and adhesion enhancement in Edilizia del Benessere®, where the strictly natural origin of its ingredients ensures the required basic parameters of porosity, hygroscopicity and air permeability.

Biocalce® Rinzaffo is suitable for increasing the adhesion of Biocalce breathable plasters to stone, river gravel substrates, worn substrates in monument restoration, where the choice of consciously dosed traditional ingredients such as natural lime, natural pozzolan, stone, marble and granite ensures the existing structures and the original conservation intervention with respect for materials.
