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
Match primer, substrate and application rate to the membrane manufacturer. Set the actual required coat count.
