Series 16 – Practical Research on Inter-war Plaster

The practical research for the repair of the simili pierre wall is at the stage where completely damaged areas are being restored. The loose plaster has been removed. The masonry substructure has been rebuilt as it was completely eroded and unstable because of high humidity levels. The new structure has been plastered with a plaster of simili pierre and is being worked on according to the original design.

First, some plaster samples were taken to determine the size and composition of the grains. In order not to alter the colour, no sand was used, only white stone dust in a proportion of 1/2 (cement/marble dust).

The plaster is applied and left for about a day to harden, after which the design is traced and then the surface is smoothened.

Smooth edges are produced by levelling the surfaces when applying plaster.

There is a difference in colour from the old plaster, but this is due to the ageing of the old finish and erosion over time by water, wind and sun.
