Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Base volume = floor length × floor width × average thickness. Waste is added, then bags = round up (order volume ÷ mixed yield per bag).
FAQ
Floor Screed Calculator questions
Is floor screed the same as self-leveling compound?+
No. Screed is generally installed thicker and uses a different mix and placement method than many self-leveling products.
Why use average thickness?+
Existing floors are often uneven. The average placed thickness gives a better volume estimate than the minimum depth alone.
Where can I find bag yield?+
Use the mixed-volume yield stated by the manufacturer for the exact product and water ratio.
