Restoration of a Roman Cement Frieze

This period town house in Truro had a decorative frieze and ornate keystones cast in Roman cement that has suffered badly from frost damage. A good example of the damage the wrong paint will do over time to traditional renders and mortars. The synthetic paint had not allowed the render and masonry behind to breath, trapping in moisture which has periodically frozen and expanded during the winter months and caused the render as well as the ornate details to fail and deteriorate over time.

We were asked to re-cast the ornate frieze and keystones and reinstate once the façade had been re-rendered in hydraulic lime.

We were able to salvage a repeat section of the frieze as well as some elements of the keystones for mould taking before the render was removed. Once cleaned and repaired we were able to take an exact mould of the originals and re-cast them using a French natural cement called Vicat Prompt.
