# How Much Sand Required For 100 Square Feet Plaster?

We require 4.9 cft sand and 49.5 kg or 1 bag of cement for 100 square feet plaster work considering 12 mm thickness of plastering layer and 1:4 ratio of mortar mix.

## Sand Required For 100 Square Feet Plaster (1:4 Ratio)

Here 1:4  mortar ratio is considered for plastering, in which 1:4 mortar ratio means 1 part of cement and 5 parts of sand. Also, we are considering thickness of plastering layer as 12 mm for 100 square feet area.

1. Requirements for Plastering Work
1. Area of plastering = 100 sqf
2. Mortar Ratio = 1:4
3. Thickness of plastering layer = 12 mm
4. Wastage factor and shrinkage factor = 1.54

2. Wet Volume of Mortar For 100 Sqf Plastering Area
Volume of Plastering Area
= Area of Plastering × Thickness of Mortar Layer
= 100 sqf × 12 mm
= 9.3 m² × 0.012 m
= 0.1116 m³

3. Dry Volume of Mortar For 100 Sqf Plastering Area
Dry volume of plastering material
= Volume of Plastering × Factor of Wastage and Shrinkage
= 0.1116 m³ × 1.54
= 0.171864 m³

4. Quantity of Cement Calculation
Quantity of Cement
= Dry Volume of Mortar × Density of Cement × (Proportion of Cement / Total Sum of Proportion)
= (0.171864 m³) × (1440 kg/m³) × (1/5)
= 49.5 kg (One bag cement)

5. Quantity of Sand Calculation
Quantity of Sand
= Dry Volume of Mortar × (Proportion of Sand / Total Sum of Proportion)
= 0.171864 m³ × (4/5)
= 0.1375 m³
= 4.9 cft

## Sand Required For 100 Square Feet Plaster (1:5 Ratio)

Here 1:5  mortar ratio is considered for plastering, in which 1:5 mortar ratio means 1 part of cement and 5 parts of sand. Also, we are considering thickness of plastering layer as 12 mm for 100 square feet area.

1. Requirements for Plastering Work
1. Area of plastering = 100 sqf
2. Mortar Ratio = 1:5
3. Thickness of plastering layer = 12 mm
4. Wastage factor and shrinkage factor = 1.54

2. Wet Volume of Mortar For 100 Sqf Plastering Area
Volume of Plastering Area
= Area of Plastering × Thickness of Mortar Layer
= 100 sqf × 12 mm
= 9.3 m² × 0.012 m
= 0.1116 m³

3. Dry Volume of Mortar For 100 Sqf Plastering Area
Dry volume of plastering material
= Volume of Plastering × Factor of Wastage and Shrinkage
= 0.1116 m³ × 1.54
= 0.171864 m³

4. Quantity of Cement Calculation
Quantity of Cement
= Dry Volume of Mortar × Density of Cement × (Proportion of Cement / Total Sum of Proportion)
= (0.171864 m³) × (1440 kg/m³) × (1/6)
= 41.25 kg

5. Quantity of Sand Calculation
Quantity of Sand
= Dry Volume of Mortar × (Proportion of Sand / Total Sum of Proportion)
= 0.171864 m³ × (5/6)
= 0.1432 m³
= 5.1 cft

So, we require 5.1 cft sand and 41.25 kg cement for 100 square feet plaster work considering 12 mm thickness of plastering layer and 1:4 ratio of mortar mix.
