● What is plastering procedure:- Plaster is a thin layer of mortar applied over the rough surface of brick wall and it acts as “damp proof coat” over the brick work .plastering also provide fine and finish surface over the brick wall that is firm and smooth and it enhances the appearance of of brick wall building.

● Thickness of plastering work: There is a two types of plastering work first one is internal plastering of brick wall and second one is external plastering of brick wall.
In internal plastering of brick wall plaster thickness is about 12 mm and in the case of external plastering work of brick wall plaster thickness is about 15 mm to 20 mm, and also plastering work is done on the RCC slab ,in the case of RCC plastering thickness is about 6 mm.
●What are different types of plastering work
● (1) lime plaster:- in the case of lime plaster lime is used as binding material for the plastering work of brick wall
●( 2) cement plaster:-in the case of cement plaster cement is used as binding material for the plastering work of brick wall
● (3) mud plaster :- in the case of mud plaster mud is used as binding material for the plastering work of brick wall.
1 bag of cement covers how much area of plaster
1 bag cement plaster coverage area is calculated by consumption of cement and sand quantity in plaster, that is very good questions 1 bag of cement covers how much area of plaster.
1) 1 bag cement external wall plaster coverage area ( 1:6 mix ratio & 20 mm thick plastering)
Given no of cement bags = 1 bag
1 bag cement weight = 50 kg
Density of cement = 1440 kg/m3
Dry Volume of cement = weight/density
Dry volume of cement = 50/1440 = 0.0347
Dry volume of cement = 0.0347 m3
If cement sand ratio is 1:6 , than
Dry volume of sand = 0.0347 ×6 = 0.208 m3
Total volume of mortar = 0.2427 m3
For converting dry volume of mortar to wet volume we will divide by 1.33 to dry volume of mortar
Wet volume = 0.2427/1.33 = 0.1825 m3
Thickness of plaster = 20 mm = 0.020 m
Coverage area of plaster = 0.1825/0.02 = 9.125 m2
● Ans. :- 9.125 square metre is coverage area of plaster in one bag (50 kg) cement for external brick wall plastering (cement sand ratio is 1:6 & thickness 20 mm).
2) 1 bag cement internal wall plaster coverage area ( 1:4 mix ratio & 12 mm thick plastering)
Given no of cement bags = 1 bag
1 bag cement weight = 50 kg
Density of cement = 1440 kg/m3
Dry Volume of cement = weight/density
Dry volume of cement = 50/1440 = 0.0347
Dry volume of cement = 0.0347 m3
If cement sand ratio is 1:4 , than
Dry volume of sand = 0.0347 ×4 = 0.1388 m3
Total volume of mortar = 0.1735 m3
For converting dry volume of mortar to wet volume we will divide by 1.33 to dry volume of mortar
Wet volume = 0.1735/1.33 = 0.131 m3
Thickness of plaster = 12 mm = 0.012 m
Coverage area of plaster = 0.131/0.012 = 10.92 m2
● Ans. :- 10.92 square metre is coverage area of plaster in one bag (50 kg) cement for internal brick wall plastering (cement sand ratio is 1:4 & 12 mm thickness).
1 bag of cement covers how much area? around 9 to 11m2 (square metre) is coverage area of plaster in 1 bag of cement, external plaster coverage is around 9 square metre and internal plaster coverage is around 11 square metre in 1 bag of cement.
1 bag of cement covers how much area
A bag or sack of cement is 94 lb (43 kg) in the United States; for other kinds of cement, a quantity is indicated on the bag.
1 bag or sack of Portland cement covers approximately 84 square feet area (8m2) for external wall plastering by using standard cement mortar mix of 1 part of cement to 6 parts of sand. For internal wall plastering coverage area is around 100 square footage in a sack of cement.
Cement mortar calculation for 1m2 plastering
●Given dimension:-
Brick wall size = 1 m× 1m
Mortar thickness in the case of internal plaster work t = 12 mm
● solve:-
Wet volume of mortar = A× t
Vw = wet volume
Vw = 1m× 1m × 12mm
Vw = 1m2 × 0.012m
Wet volume = 0.012 m3
◆note:-You know that wet volumes contains water and its bubble it can be remove by pressing the Plaster that’s require more quantity of mortar material mixture of sand and cement ,that is dry volume.
hence dry volume is increased by 33% of wet volume. so we have to convert wet volume in dry volume by conversion factor multiplying 1.33
● dry volume = 1.33×wet volume
Dry volume = 1.33×0.012 m3
Dry volume = 0.01596 m3
● ratio of sand and cement:- Ratio of sand andment which are used in plastering work of brick wall is 1:6, in this ratio 1 part is cement and 6 part is sand.
● mix ratio = 1:6
Total R = 1+6 =7
Dry volume =0.01596 m3

● Quantityof cement for plastering in kg:–
Weight of cement = volume ×density
Density of cement= 1440 kg/m3
Weight = 1/7×0.01596 m3×1440 kg/m3
Weight of cement =3.28 kg
Some amount of Cement Solution are also used as binding material for plastering work it will be about 25%
Weight of Cement Solution=3.28×25/100
=0.82 kg
Now Total weight of cement required for plastering work= 3.28 kg+ 0.82 kg=4.1kg Ans.
4.1 kg cement quantity is required for plastering of 1 square metre brick wall
● Quantity of sand in CFT:- in the mix ratio of mortar 6 part is sand used in plastering work of brick wall
Volume of sand = 6/7×0.01596m3
1 m3 = 35.3147 ft3
Putting this value we get
Volume of sand =6/7×0.01596 × 35.3147 cft
Quantity of sand =0.483 CFT Ans.

calculate the quantity of sand and cement in 1 foot2 plaster work
Solve :- first you should convert given area 1 metre square into foot square
We know that 1m2 = 10.76 foot square
Given area 1 metre square require 4.1 kg cement and 0.483 cft sand so we have
10.76 ft square area of plastering work require 4.1 kg sand and 0.483 cft sand
So sand quantity for 1 foot square plaster work
Sand quantity/ft2 = 0.483 cft÷10.76
Sand quantity/ft2 = 0.0449 cft
Now cement quantity for 1 foot square plaster work
Cement quantity/ft2 = 4.1÷10.76 kg
Cement quantity/ft2 =0.38 kg
So 1 square foot plaster work require
Sand quantity = 0.0449 cft
Cement quantity = 0.38 kg

Coverage area of plaster in one bag cement
● Solve :-
Calculation of area of plaster work in foot square by one bag cement ,we know that
1 bag cement = 50 kg
1 square foot plaster work require 0.38 kg of cement
0.38 kg for 1 ft2 plaster
1 kg cement for 1ft2/0.38kg plaster
50 kg cement for 1 ft2/ 0.38 kg × 50 kg plaster
= 131 square feet plaster
Coverage area of plaster is 131 square feet in one bag cement.
Conclusion:-
1 bag or sack of Portland cement (94lb) covers approximately 84 square feet area (8m2) for external wall plastering by using standard cement mortar mix of 1 part of cement to 6 parts of sand. For internal wall plastering coverage area is around 100 square footage in a sack of cement.
