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
Use coverage per coat from the product label. Rough or absorbent surfaces may need more paint.
