How many cement bags per square meter for plastering?

The number of cement bags required for plastering a square meter depends on various factors such as the thickness of the plaster and the mix ratio. On average, for a 15mm thick plaster, you might need around 0.02 to 0.04 cubic meters of mortar per square meter.

How many cement bags per square meter for plastering? cement bags required for 1 sq m plastering, hi guys in this post we know about how much cement is required for plastering of 1 square meter area & also know about cement required for 1 sq m in 12mm & 20mm thick plaster.

Requirement of plastering material cement and sand calculation in plaster of brick wall depends on mostly two factors such as

1) Thickness of Plaster

2) Mix Ratio (Cement:Sand)

Thickness of cement plaster:- The typical thickness of cement plaster is range from 6 mm to 20 mm (or 0.25 to 0.8 inch). In construction, 6mm is recommended for plastering ceilings and concrete, 12mm for plastering interior walls and 20mm for plastering exterior walls.

● 6 mm thick cement plaster are used for ceiling and concrete plastering

● 12 mm thick cement plaster are used for internal wall plastering and plane surface of brick wall

● 15 mm or 20 mm thick cement plaster used for external wall plastering and rough surface of brick wall

Mix ratio for cement plaster : there are several types of mix ratio used for brick wall plastering, ratio of cement and sand for plastering depends on types of work and plastering types it is rough or plane surface.

In construction, 1:4 mix ratio of cement and sand is recommended for plastering exterior walls and ceilings 1:6 mix ratio for plastering interior walls (if fine sand), 1:5 mix ratio for plastering interior walls (if coarse sand), and 1:3 mix ratio for plastering external walls prone to sever climatic.

● 1:3 mix ratio of cement and sand are used for plastering of external wall prone to sever climatic condition and for repairing work

● 1:4 mix ratio of cement and sand are used for external brick wall plastering and ceiling plastering

● 1:5 mix ratio of cement and sand are used for internal brick wall plastering when fine sand is not available

● 1:6 mix ratio of cement and sand are used for internal wall plastering when fine sand is available.

In construction, 1:4 mix ratio of cement and sand is recommended for plastering exterior walls and ceilings 1:6 mix ratio for plastering interior walls (if fine sand), 1:5 mix ratio for plastering interior walls (if coarse sand), and 1:3 mix ratio for plastering external walls prone to sever climatic.

Cement bags required per square meter plastering 12mm plaster & 1:4 ratio

For a Sample calculation, I will assume a 12mm (0.012m) thick plaster and a mix ratio of 1:4 for plastering of 1 square metre brick wall

● Step-1: we know given area of brick wall = 1 sq m

● Step-2: Volume of brick wall plaster = Area X Thickness = 1 X 0.012 = 0.012 m3

Since wet volume is always less than the dry volume. For converting wet volume to dry volume of mortar we will multiply 1.33 into wet volume.

The dry volume of mortar required for brick wall plastering = 1.33 X Dry volume of plaster = 1.33 X 0.012 = 0.01596 m3.

● Step-3: The mix ratio of mortar is 1:4, So total ratio = 1+4 = 5 in which one part is cement and 4 parts is sand

Cement required = 1/5 X 0.01596 = 0.003192 cu m ( cubic meter)

Sand required = 4/5 X 0.01596 = 0.01277 cu m

● Step-4: To get the weights of materials required in multiply this with density and convert cubic feet into cubic meter

Cement required in kg = 0.003192 cum X 1440 kg/cum = 4.6 Kgs, cement required in CFT = 0.003192 cum × 35.32 = 0.113 cubic feet, and cement required in bags = 4.6/50 = 0.092 bags.

Since Sand density is 1620 kg/m3

The quantity of sand required in kg = 0.01277 ×1620 = 21Kgs, in CFT = 0.01277 × 35.32 = 0.45 cubic feet

That’s 21 kg (or 0.013 m3 or 0.45 CFT) of sand and 0.092 bags of 50 kg (or 4.6 kg or 0.0032 m3 or 0.123 CFT) cement is used per square meter for plastering 12mm plaster & 1:4 ratio.

Cement bags required per square meter plastering 20mm plaster & 1:4 ratio

Cement required for 1 sq m plastering of brick wall :- For a Sample calculation, I will assume a 20mm (0.020) thick plaster and a mix ratio of 1:4 for plastering of 1 sq m brick wall

● Step-1: we know given area of brick wall = 1 sq m

● Step-2: Volume of brick wall plaster = Area X Thickness = 1 X 0.020 = 0.020 cu m

Since wet volume is always less than the dry volume. For converting wet volume to dry volume of mortar we will multiply 1.33 into wet volume.

The dry volume of mortar required for brick wall plastering = 1.33 X Dry volume of plaster = 1.33 X 0.020 = 0.0266 cu m.

● Step-3: The mix ratio of mortar is 1:4, So total ratio = 1+4 = 5 in which one part is cement and 4 part is sand

Cement required = 1/5 X 0.0266 = 0.00532 cu m ( cubic meter)

Sand required = 4/5 X 0.0266 = 0.02128 cu m

● Step-4: To get the weights of materials required in multiply it with its density and convert cubic feet into cubic meter

Cement required = 0.00532 cum X 1440 kg/cum = 7.7 Kg, in CFT = 0.00532 ×35.32 = 0.188 cubic feet, in bags = 7.7/50 = 0.154 bags.

Since Sand density = 1620 kg/m3

Then quantity of sand = 0.02128 × 1620 = 34.5 Kg, in CFT = 0.02128 × 35.32 = 0.75 cubic feet.

That’s 35 kg (or 0.02128 m3 or 0.75 CFT) of sand and 0.154 bags of 50 kg (or 7.7 kg or 0.00532 m3 or 0.188 CFT) cement is used per square meter for plastering 20mm plaster & 1:4 ratio.

The dry volume of mortar required for brick wall plastering = 1.33 X Dry volume of plaster = 1.33 X 0.015 = 0.02 m3

● Step-3: The mix ratio of mortar is 1:4, So total ratio = 1+4 = 5 in which one part is cement and 4 parts is sand

Cement required = 1/5 X 0.02 = 0.004 cu m ( cubic meter)

Sand required = 4/5 X 0.02 = 0.016 cu m

● Step-4: To get the weights of materials required in multiply it with its density and convert cubic feet into cubic meter

Cement required = 0.004 cum X 1440 kg/cum = 6 Kg, in CFT = 0.004 ×35.32 = 0.14 cubic feet, in bags = 6/50 = 0.12 bags.

Since Sand density = 1620 kg/m3

Then quantity of sand = 0.016 × 1620 = 26 Kg, in CFT = 0.016 × 35.32 = 0.57 cubic feet.

That’s 26 kg (or 0.016 m3 or 0.57 CFT) of sand and 0.12 bags of 50 kg (or 6 kg or 0.004 m3 or 0.14 CFT) cement is used per square meter for plastering 15mm plaster & 1:4 ratio.

Sand required for 1 sqm plastering

The typical amount of sand required for 1 m2 (1 square meter, 1 sqm) of plaster is 20-24 kg. For plastering the external and internal walls, 20-24 kg of sand per square meter are required. Usually sand requirement for plastering depends on thickness of plaster wall and the proportions of the mixture.

How many cement bags required per square metre for plastering?

The typical amount of cement required for 1 m2 (1 square meter, 1 sq m) of plaster is 5-6 kg (or 0.1-0.12 bags of 50 kg). For plastering the external and internal walls, 5-6 kg (or 0.1-0.12 bags of 50 kg) of cement per square meter are required. Usually amount of cement required for plastering depends on thickness of plaster wall and the proportions of the mixture.
