Whenever used for plastering, the setting time of the mortar of Plaster of Paris and sand is normally five minutes. Hence, it is very much risky to enable the application to the surfaces before its setting is done.
Generally, the dry mix of the plaster of Paris along with sand is prepared on the impervious platform and in this particular case small quantity of mix is taken into the process and carried out to the masons. After it, the masons will add water to the dry mix whenever it has to be used, and this particular plaster serves as a very good quality plaster because it gives proper and smooth finishing throughout the process.
