Development of Maintenance and Conservation Methods for Historical Architecture Using Plaster Wall Materials

Part9 Plaster Fresh Properties of Wooden Lath and Plaster Celling in Historical Architecture

Abstract

In order to understand the soundness of the wood plaster ceiling as a component, we will approach it from the conditions at the time of construction and the kneading properties of the plaster. The plastering specifications of the heritage building at the time of its construction did not specify the amount of water used for plastering. This is because the hardness of the plaster after kneading was relatively left up to the site. This is due to the fact that the hardness of the plaster after kneading was relatively left up to the job site, and even today, such kneading properties are largely based on the senses of the technician. This enabled us to collect basic data to clarify the relationship between the technician's senses, the amount of water kneaded, and the flow.
