Screed / plaster

Area and thickness → bags.

How we calculate it

What you enter

  • Area (m²)
  • Thickness (mm)
  • Bag (kg)

Formula

kilograms = Area × Thickness × 2.0
bags = ⌈ kilograms ÷ Bag ⌉

Example

The default values from the form, run through the same engine:

To buy
64 bags
kg1600 kg

What to watch out for

The conversion assumes a density of about 2.0 kg per litre of mortar. Anhydrite screeds and lightweight screeds have a different density — check the bag.

The Materio app for Android uses the same formula. The site's engine is a 1:1 port of the app's code.
