Formula
Gallons = (area ÷ coverage) × coats.
Cost = gallons × your price per gallon. Coverage is square feet per gallon for one coat.

Sealcoat calculator for gallons and coats
This sealcoat calculator divides the area by the coverage you enter, then multiplies by the number of coats. Cost is gallons times your price per gallon. Coverage and price are estimates you type, not a supplier quote.

Planning estimate from the numbers you enter. Coverage, density, waste and price are assumptions, not a supplier quote or an engineering specification.
How it works
Gallons equal area divided by coverage, times coats.
Five thousand square feet at 80 square feet per gallon is 62.5 gallons for one coat and 125 gallons for two coats. At $4 per gallon the material estimate is $500. Eighty square feet per gallon is a planning default, not a promise for a rough or steep lot. A thirsty first coat covers less. Lower the coverage when the surface soaks the sealer in. This sealcoat calculator does not add crack fill or labor unless you fold them into the gallon price.

Example
5,000 square feet, 80 square feet per gallon, 2 coats, $4.
The sealcoat calculator shows 125.00 gallons and a $500 material estimate. One coat would be half the gallons.
03
Tips
Coverage falls on a rough or oxidized surface.
If the last job used more gallons than the label suggested, type that lower coverage. Do not keep 80 just because it is filled in.

Equipment
The sprayer or the squeegee rig is the equipment.
Dengaro arranges financing for paving equipment. Gallons are not a loan amount.
Important questions
Know what to expect.
Is 80 square feet per gallon realistic?+
Only if your material and your surface say so. It is the default so the example has a number.
Does the price include labor?+
No, unless you raised the price per gallon to include it. The form has no separate labor field.
How do I handle coats with different coverage?+
Run the page twice, once per coat, and add the gallons. Or type an average coverage and two coats.
Is this an asphalt tonnage?+
No. Tons of asphalt are on the asphalt calculator. This page is the sealer on top.
