Asphalt Sealer Calculator
Calculate how much asphalt sealer you need for your driveway, parking lot, or road. Determine gallons needed, coverage, drying time, and total cost based on area and sealer specifications.
Step 1: Area Specifications
Area Calculation Tips
For irregular shapes, break the area into rectangles, calculate each separately, then add them together. Most driveways require 2 coats for proper protection.
Step 2: Sealer Parameters
About Sealer Coverage
Coverage rates vary by sealer type and surface condition. Coal tar sealers typically cover 80-100 sq ft per gallon. Rough or porous surfaces may require more sealer.

Sealer Calculation Formula
Gallons = (Length × Width × Coats) / Coverage Rate
To calculate sealer needed: Multiply length by width to get area, multiply by number of coats, then divide by coverage rate (sq ft per gallon). Material cost = Gallons × Price per gallon.
