Plastering deductions as per is code

Question

Accepted Answer

Plastering deductions as per IS code refer to the deductions made in plastering thickness as per Indian Standards code.

IS code specifies deductions for plastering thickness based on the type of surface and the type of plaster used.
For example, for a smooth surface and cement plaster, the deduction is 6mm for internal walls and 8mm for external walls.
Similarly, for a rough surface and lime plaster, the deduction is 12mm for internal walls and 15mm for external walls.
These deductions are made to account for the thickness of the plaster and ensure that the final surface is even and level.
It is important for a billing engineer to be aware of these deductions to accurately calculate the quantity of materials required for plastering.
