Professional Screed Calculator – Sand, Cement & Liquid

Overview

When starting a construction or flooring project, one of the most important steps is calculating how much material you need. Ordering the wrong amount can lead to wasted money, delays, or poor-quality results. To make things easier, our Professional Screed Calculator provides accurate estimates for both traditional sand & cement screed and modern liquid screed.

This tool is designed for contractors, architects, and homeowners who want fast and reliable calculations without complex manual formulas.

Use joist calculator.

What Is Screed?

Screed is a thin layer of material applied to a concrete floor base, creating a smooth, level surface. It is widely used to:

• Prepare floors for tiles, wood, or vinyl

• Cover underfloor heating systems

• Provide durability and strength to floor finishes

The two most common types are:

• Traditional Sand & Cement Screed – A 1:4 mix ratio of cement to sand.

• Liquid Screed (Flowing Screed) – A modern self-leveling alternative with faster installation.

Sand & Cement Calculator

The Sand & Cement Screed Calculator helps estimate the amount of material needed for your project.

How it works:

1. Enter the area in square meters.

2. Enter the depth in millimeters.

3. Instantly get results for:

   • Sand in tonnes

   • Cement in 25kg bags

This saves time and ensures that you purchase the exact amount required.

Why it’s useful:

• Prevents over-ordering and extra costs

• Accurate calculations for small and large areas

• Based on the standard 1:4 mix ratio

Liquid Screed Calculator

Liquid screed is becoming increasingly popular because of its self-leveling properties and efficiency.

How it works:

1. Enter the area in square meters.

2. Enter the depth in millimeters.

3. The calculator shows the volume in cubic meters (m³).

Benefits of liquid screed:

• Faster to install than traditional screed

• Creates a perfectly flat surface

• Excellent for underfloor heating systems

• Reduced drying time compared to sand & cement

Traditional vs Liquid Screed

Choosing between sand & cement and liquid screed depends on your project.

• Traditional Sand & Cement Screed

  • Durable and cost-effective

  • Suitable for residential and commercial floors

  • Requires 24–48 hours drying before light use

• Liquid Screed

  • Self-leveling, fast, and modern

  • Provides better thermal conductivity

  • Perfect for energy-efficient buildings and underfloor heating

How to Use the Calculator

Using the Screed Calculator is simple:

1. Select your screed type (Sand & Cement or Liquid).

2. Input the project area in m².

3. Input the required depth in mm.

4. Get instant results for your material needs.

This process takes less than a minute and provides accurate values you can use for ordering.

FAQs

1. What is the standard mix ratio for traditional screed?
The ratio is 1 part cement to 4 parts sand (1:4).

2. Can I use liquid screed for small projects?
Yes, it is suitable for both small rooms and large commercial sites.

3. How long does traditional screed take to dry?
It typically requires 24–48 hours before walking and longer for full curing.

4. Why is liquid screed better for underfloor heating?
Its self-leveling property allows better heat transfer and efficiency.

Conclusion

The Professional Screed Calculator is the simplest way to estimate your material needs for both traditional sand & cement screed and liquid screed. By entering just the project area and depth, you’ll instantly know how much sand, cement, or liquid screed to order.
