PLASTERING RATES PER m2

 

PART A ) MATERIAL COST 
PART B ) LABOR COST 
We will calculate plastering cost considering material cost and labor cost and will not include other expenses as Cost of working tools ,Labor Accommodations,  Labor transportations, Scaffolding cost Shifting of mortar material in high rise buildings because there are variations which depends on nature of projects with different leads and lifts.
In ideal conditions 1 -Mason and 1 Helpers along with 2  Labor for shifting and mixing of mortar can easily do 14-Sq.m of plastering with complete perfection. After years of experience it has been known that "A" Class  Mason can do 14-Sq.m of plastering in 8 Hours and "B" Class mason can do 9.30 Sq.m  of plastering in 8 Hours.

CALCULATION FOR PLASTERING MATERIALS 
WET VOLUME = AREA OF PLASTERING XTHICKNESS OF PLASTER
DRY VOLUME = WET VOLUME X 1.27 
1.27 IS DRYING FACTOR 
1- QUANTITY OF CEMENT IN BAGS = 
(CEMENT BY PART x  DRY Volume) / (Sum of ratio x Vol of one bag of cement)
2- QUANTITY OF SAND IN Cu.m  = 
(SAND BY PART x  DRY Volume) / (Sum of ratio)
3- QUANTITY OF WATER  IN LITERS  = 
NOS OF CEMENT BAGS x 50 x 2 x14 days of curing=  Liters of water

Daily Material Quantities when "A" Class Masons working
