    How it works

    The formula

    pails = area × coats ÷ coverage per pail, rounded up

    Assumptions

    • Coverage per 4.75 gal pail: 400 sq ft on smooth or previously sealed asphalt and 300 on rough or unsealed, the low ends of Latex-ite's 400 to 500 and 300 to 400 sq ft. Check your product's label.
    • Two thin coats wear better than one thick one; each coat uses about the same amount.
    • Typical price $25–$37 per pail (checked Oct 2026). Fill cracks first; crack filler is extra.

    Questions people ask

    How much does a 4.75 gallon pail of sealer cover?

    About 300 to 400 sq ft per coat on rough or unsealed asphalt and 400 to 500 on smooth or previously sealed asphalt, per Latex-ite's labels.

    How often should I seal my driveway?

    Every two to three years is common for residential asphalt; sealing too often builds up a layer that can crack and peel.

    What temperature do I need?

    Most water-based sealers need dry weather and at least about 50 to 55°F, day and night, to cure. Latex-ite's Airport Grade+ asks for at least 55°F at night.
