Ciment et Architecture

Glossary

Render

Coating comprised of one or more layers of a plastic material used for the protection (water, insulation, etc.) and presentation of the structure it covers. It is applied in three stages: roughcast or base coat, filling (Floating coat) and rubbed finish.

Repointing

Repairing of joints with a cement mortar. Joints can be hollow or embossed, although hollow joints better protect masonry against water infiltration.

Restoration

Restoration is direct action undertaken not only to improve the condition, knowledge and understanding of a cultural asset, but also to exhibit, use and understand it. It is undertaken only when the asset has lost some of its meaning or its function because of alterations or past reorganisations which prevent understanding and/or interpretation.

Roman cement

The commercial name of natural cement invented in England by Parker at the end of the 18th century. Roman cement was the term used for all hydraulic products resulting from very argillaceous limestones that were subject to moderate temperature and mechanically pulverized.

Roughcast or base cast

First coat of a render whose primary role is to ensure bonding to the surface.
