What is the difference between traditional plastering and using plaster machine?

Depending on the complexity of your project, number of manpower can Vary during the project life cycle, yet, also depending on the skilled manpower available in the country to do that specific task, activity and project.

For example, here in United Arab Emirates, productivity of manpower can vary as an example; wall plastering. There are number of ways for the plaster work such as the traditional way (Sand and cement) mix. This traditional way mixed manually with water using hand shovel and other tools. There are also the spray machine, this way is not new way here in UAE but it has been widely used in large scale projects with many quantities and companies use either silo or 50 kgs bags. It depends on the logistic preparation of the project, for high rise buildings. Some times it is difficult to use the silo since it needs long rubber pips and pumps to pump the dry mix to the required level and many technical issues may appear in daily basis. Personally I prefer to use the machine with bags for such projects.
