ripascimento

Ripascimento is a technique used in the restoration of historic buildings, particularly in the context of masonry structures. The term originates from the Italian word "ripassare," which means to pass over or repeat. The process involves the removal and replacement of old mortar and stonework with new materials, aiming to restore the original appearance and structural integrity of the building.

The technique is often employed when the original materials have deteriorated due to age, weathering, or other forms of damage. Ripascimento can be applied to various types of masonry, including stone, brick, and terracotta. The process typically involves several steps:

1. Cleaning the surface to remove dirt, loose material, and any remaining old mortar.

2. Preparing the surface by applying a primer or bonding agent to ensure proper adhesion of the new materials.

3. Applying a new layer of mortar or plaster, often using traditional techniques to mimic the original appearance.

4. Replacing damaged or missing stones with new ones, carefully matching the size, shape, and color to the originals.

5. Finishing the surface with a final coat of mortar or plaster to achieve a smooth and uniform appearance.

Ripascimento is a labor-intensive and time-consuming process that requires skilled craftsmen with a deep understanding of historic masonry techniques. It is often used in the restoration of historic churches, castles, and other significant buildings, where preserving the original appearance and integrity is of utmost importance. The technique has been used for centuries and continues to be an essential tool in the conservation of historic architecture.
