Plaster Calculator

Calculate cement & sand for wall plastering.

Enter wall dimensions

About This Tool

Calculate the materials needed for plastering internal or external walls. Plastering protects masonry and provides a smooth finish. This tool lets you define the plaster thickness (usually 12mm for internal, 20mm for external walls) and the mix ratio (usually 1:4 or 1:6). It subtracts openings like doors and windows from the total area to give you a realistic estimate of cement bags and sand volume. This tool has become indispensable for construction professionals across India, from small contractors to large construction firms. It accounts for industry-standard specifications and local building codes, ensuring your estimates are accurate and reliable. The calculator helps prevent costly mistakes like material shortages mid-project or excessive wastage that impacts your budget. Whether you're bidding on a project, planning a renovation, or managing a large construction site, this tool provides the precision you need for successful project execution. It saves hours of manual calculations and reduces the risk of human error in critical construction planning. Our algorithms are optimized for performance, ensuring instant results even for complex calculations. We are committed to providing free, high-quality tools to help you be more productive. Our platform is dedicated to simplifying your digital life with an extensive collection of utilities that are always available at your fingertips, completely free of charge and without any registration requirements. We believe in open access to technology for everyone.

How to Use This Tool

1

Wall Area

Enter Length and Height of walls.

2

Openings

Enter area of doors/windows to subtract.

3

Specifications

Choose Thickness (e.g., 12mm) and Ratio (e.g., 1:4).

4

Calculate

Get exact cement and sand quantities.

Key Features

  • Area Calculation: Easily deduct door/window openings.
  • Thickness Control: Separate calculations for 12mm, 15mm, or 20mm coats.
  • Mix Ratios: Support for rich (1:3) or lean (1:6) mortar mixes.
  • Cost Estimation: Helps in budgeting finishing costs.

Frequently Asked Questions

What is the standard ratio for plaster?

For internal walls, 1:6 (Cement:Sand) is common. For external walls and ceilings, a richer 1:4 mix is preferred.

How much extra should I order?

Plastering often has higher wastage (rebound loss). We suggest adding 15-20% to the calculated quantity.
