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 density for the selected product at the stated thickness. For product-specific dry coverage, use the supplier rate.
Quantity and arithmetic estimates only. Use project specifications for installation and design requirements.
