Screed Materials Calculator の使い方 — calculate floor screed quantity and weight
Calculate screed volume, estimated mass and bag count from floor area, average thickness, density, pack size and waste.
Screed volume = floor area × thickness in metres. Mass = volume × selected product density, including the chosen waste allowance.
Calculate screed volume, estimated mass and bag count from floor area, average thickness, density, pack size and waste. The linked Sellible tool keeps the fields, units and output together so the assumptions can be reviewed before the result is used.
- 1
Measure the net floor area.
- 2
Use the designed average thickness, including falls where relevant.
- 3
Select the product density and bag size from its data sheet.
Example values and result
These values demonstrate the method; replace them with measurements, rates or file details that match the real task.
- Floor area
- 30 m²
- Average thickness
- 50 mm
- Density
- 2,000 kg/m³
- Waste allowance
- 10%
The floor needs 1.50 m³ geometrically before waste. The displayed mass helps with product, handling and loading discussions but is not a structural verification.
精度と実用上の注意
- Confirm bonded, unbonded or floating construction.
- Check minimum thickness and reinforcement requirements.
- Verify floor loading with the responsible professional.
Common mistakes
- Entering millimetres as metres.
- Assuming the whole floor has one depth when levels vary.
- Using estimated weight as structural approval.

よくある質問
Is Screed Materials Calculator free?
Yes. This calculator or browser utility is free and does not use processing credits.
Can I use this guide and Screed Materials Calculator on a phone?
Yes. The guide, inputs, results and calls to action are responsive and keyboard accessible on current phones, tablets and desktop browsers.
Should I order or make a decision from the estimate alone?
No. Confirm bonded, unbonded or floating construction. Check minimum thickness and reinforcement requirements. The calculation is a planning aid rather than professional or regulatory approval.
How should I check the result?
Keep the source values and units visible, compare the result with supplier or project information, and retain enough precision until the final purchasing or reporting step.
