RC ASTIVO

Coloured Pre-dosed Natural Hydraulic Lime (NHL 3.5) for Jointing Mortar

General

RC ASTIVO is a premium, pre-dosed binder based on natural hydraulic lime (NHL 3.5), specially developed for the preparation of durable pointing mortars in accordance with ENV 459-1 standards. This binder combines excellent breathability with a natural composition, allowing effective moisture evaporation from masonry and reducing damage caused by salt migration. RC ASTIVO offers an ideal solution for the restoration and protection of both historic and modern facades.

The product is used for pointing brickwork, terracotta, and natural stone (excluding marble and granite). Thanks to its outstanding elasticity and vapour permeability, RC ASTIVO is particularly suited for renovation projects, heritage conservation, and eco-friendly construction. It provides a strong yet flexible joint resistant to movement and shrinkage, contributing to a healthy indoor climate.
