How The Calculation Works
Formulas, material coverage assumptions, waste buffers, and rounding standards.
Coverage depends heavily on surface porosity. A smooth, previously sealed driveway takes roughly 400 sq ft per 5 gallon pail, while a rough oxidised surface can drop below 250.
Two thin coats outperform one thick coat consistently — a heavy single application skins over on top, stays soft underneath, and tracks onto shoes and tyres for weeks.
Crack filler is estimated separately from sealer, because cracks must be filled and cured before any sealer goes down.
