How many bags of cement and sand for 270 square meters of plastering?

To calculate the amount of cement and sand needed for plastering 270 square meters, you can use a typical mix ratio, such as 1 part cement to 4 parts sand. Assuming a plaster thickness of about 12 mm, you would need approximately 1.5 cubic meters of plaster. This translates to roughly 300 kg of cement (about 6 bags of 50 kg each) and about 1.2 cubic meters of sand. Always consult a local expert for precise calculations based on specific conditions and mix ratiOS.
