YOUR ESTIMATE
Bags to buy
Whole quantities are rounded up.
How it's calculated
Mass = area × applied thickness × density × (1 + waste ÷ 100). Bags = mass ÷ bag size, rounded up.
Calculations use consistent units for your selected measurements. The waste allowance is applied once to the measured requirement. Whole purchase quantities are rounded up.
What this estimate includes
Use the manufacturer mass per applied volume, not loose powder bulk density. For example, 1.7 kg/m² per mm is 1700 kg/m³.
Quantity and arithmetic estimates only. Use project specifications for installation and design requirements.
