Learn how to calculate cement and sand quantity required for plastering 100 sq.m of internal wall with a simple step-by-step handwritten calculation.

Given:

Wall Area = 100 sq.m
Plaster Thickness = 12 mm
Mix Ratio = 1:4 (Cement : Sand)
Dry Volume Factor = 1.33

Calculation Includes:

✅ Wet volume of plaster
✅ Dry volume calculation
✅ Cement quantity
✅ Sand quantity
✅ Cement bags calculation
✅ Material estimation for plaster work
✅ Wastage consideration

Final Quantity:

🔹 Cement ≈ 9–10 bags (50 kg)
🔹 Sand ≈ 1.28 m³

This method is useful for Civil Engineers, Site Engineers, Quantity Surveyors, Estimation Engineers, Diploma Civil, B.Tech Civil, GATE, SSC JE, RRB JE, and construction professionals.
