Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Sealcoat volume = pavement area × coats ÷ product coverage. The waste allowance is applied before dividing by pail volume and rounding up.

FAQ
Asphalt Sealcoat Calculator questions
Should coverage be entered per coat?+
Yes. Enter the product coverage for one applied coat, then choose the number of coats planned.
Does this include crack filler?+
No. Crack repair, patching and primer are separate from the sealcoat volume.
Why might rough asphalt need more material?+
Open or weathered pavement holds more coating in surface voids, reducing practical coverage.
