Certified, eco-compatible, NHL 3.5 natural pure lime, natural plaster conforming to the EN 459‑1 standard, for plastering with high air permeability, ideal for GreenBuilding and for the restoration of monuments.

It contains only natural raw materials and recycled minerals. Low CO2 and very low volatile organic compound emissions. It has natural ventilation, actively dilutes indoor pollutants, and has a natural antibacterial and antifungal effect. It can be recycled as inert waste.

Kerakoll Biocalce Zoccolatura is particularly suitable for the restoration of masonry exposed to bulging, erosion and detachment due to environmental effects and the degrading effect of salt concentration caused by capillary wetting.

• It is natural, porous and highly breathable, which allows the wall to breathe freely
• Highly resistant to salts, high evaporation capacity, low capillary absorption
• Bacteriostatic and fungistatic product (CSTB method)**

Areas of use

Regenerating and protective breathable plastering of hollow and solid brick, tuff, stone and mixed masonry wet and saltpeter walls, indoors and outdoors. For the restoration of external footings exposed to staining, bulging, erosion and detachment due to permanent environmental effects and the degrading effect of salt concentration caused by capillary wetting.

Biocalce Zoccolatura is particularly suitable for creating moisture-absorbing plaster and plinths in Edilizia del Benessere®, where the strictly natural origin of its ingredients ensures the required basic parameters of porosity, hygroscopicity and breathability.

Biocalce Zoccolatura is suitable for natural breathing regeneration in monument restoration, where the choice of consciously dosed traditional ingredients such as natural lime, natural pozzolana, stone, marble and granite ensures condition-preserving interventions with respect for existing structures and original materials.
