Calculated from your measurements.

How it's calculated

Coating = (area − excluded area) × coats ÷ coverage per coat × (1 + waste ÷ 100). Containers are 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

Include additional exposed timber faces if they will be finished.
