Sealcoating is a defensive layer designed to protect your driveway from harmful elements. Sealant mixtures are bituminous- or acrylic-based liquids. The liquid base is mixed with water, silica sand, polymer additives and other fillers to achieve a premium formula. When applied on a regular schedule, sealcoating doubles the life of a driveway or parking lot.
What Is Asphalt Sealcoating?
Asphalt sealcoating involves sealing asphalt cracks to prevent ice and water from entering and disturbing the integrity of your driveway or parking lot. Over time, rain, oil and other chemicals degrade asphalt, creating a brittle surface that is both unsafe and unattractive.
Many homeowners prefer to maintain their asphalt with a pavement sealing plan. Rather than spending thousands of dollars to replace your driveway, you’ll save time and money when you apply a sealcoat product.
How Often Should You Sealcoat Your Driveway?
Experts argue over when to sealcoat asphalt driveways and parking lots. Sealcoating frequency depends on two factors: climate and the condition of your pavement. Homeowners who live in climates that experience four seasons—including hot summers and cold, wet winters—need to sealcoat more often than homeowners who live in dry, mild climates.
Generally, you should reseal your driveway or parking lot every two to three years. However, judge your driveway’s appearance with a critical eye. Is it gray and weathered? Are there small, hairline cracks? If so, you may need to reseal once a year or as needed.
How Much Does Sealcoating Cost?
The average cost to seal a two-car asphalt driveway that measures 20’ x 24’ is $100 to $190. Asphalt sealer generally costs between $.06 to $.30 per sq. ft. Costs depend on the condition of your driveway, if you use an eco-friendly sealer, and if you apply one or two coats.

How Much Driveway Sealer Will I Need?
To calculate the cost to sealcoat your asphalt driveway, find the square footage of your driveway. Then, multiply it by the sealcoat price per square foot. If you’re hiring a contractor for the job, be sure to add labor costs.
- Calculate driveway size (length x width)
- Multiply square footage by sealcoating cost (include labor costs, if necessary)
- Add 50% more if you’re applying two coats
For example, one gallon of INTEGRA-SEAL® asphalt sealer covers approximately 100 sq. ft. Coverage rate varies due to age, surface, pavement condition and porosity. Newer pavements require less sealant. Learn more in our coverage rate chart.
