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 product density appropriate to the calculation. Bag coverage from the manufacturer takes precedence.
