It is said that making a cement mixture for plastering is an art and requires true workmanship. Different workman mix concrete-cement in different ratios like some keep it 1:3, while some keep it 1:6 or 1:8 or 1:4. While the actual specification to make plaster mixture is either 1:3 or 1”4. Inappropriate ration can degrade the plaster quality. Whereas with ready mix, all required components are mixed in appropriate ratio. There one need not have to worry of maintaining ratio, etc. Also the sand, polymer and other substances used to make a ready plaster mix is of graded quality.
