Question { 9509 }

HOW we can calculate the quantity of sand and cement for 1:4
plastering with a thickness of 12 mm..total area need to be
plaster is 985 sqm

Answer

ACTUALLY I THINK
1 CUM = 35.315 CFT
12mm = .5"/ .039 feet /.012 M
so. 12 mm thick plastering = 1/ 0.012 = 83.33 Sqm

for 1 Cum cement required is in 1:4
1/4*1440 = 288 Kgs.
so, for 83.33 Sqm we need 288 kgs of cement & 288*4 = 1,152
Kgs. of sand multiply the amount with 985 & divide it by 83.33
3,404 Kgs. of Cement = 68 Bags.

Question { 8323 }

what is the procedure of plastering..?

Answer

BEFORE STARTING PLASTERING WORK IF ANY CONCRETE ELEMENTS
LIKE COLUMNS,WALLS ETC. WE HAVE TO DO POINTING / HACKING.
ALL THE SURFACES WHERE PLASTERING IS TO BE DONE SHOULD BE
WET BY APPLYING WATER. AT THE JOINTS GROOVES SHOULD BE
MAINTAINED TO AVOID CRACKS. PROPORTION OF MIXING SHOULD BE
PROPER.
