Adding a fresh coat of sealer every few years is the best way to maintain your asphalt driveway’s appearance and protect the surface from water penetration, oxidation, and cracks. Calculating how much sealer you need is essential to ensure you have the right amount for your application.
You can calculate the amount of sealer required for an asphalt driveway in a few easy steps.
The coverage rate of an asphalt sealer is a critical factor in determining how much product you need. This rate indicates the area that can be covered by a certain amount of sealer under specific conditions. Manufacturers typically provide this information on the product label, and it is expressed in square feet per gallon (sq ft/gal).
The coverage rate can vary depending on several factors:
In our experience, most products cover around 100 square feet per gallon, but some products cover more or less. We’ve also found that when applying multiple coats, the second coat uses far less sealer than the first since the first coat absorbs more sealer.
Once you know the coverage rate, you can calculate the amount of sealer needed for your driveway. Here’s the formula:
The amount of sealer required in gallons is equal to the area to be sealed in square feet divided by the product’s coverage rate in square feet per gallon.
Keep in mind that sealer is usually sold in five-gallon buckets, so if you’re project needs 7 gallons, you’ll likely need to purchase two five-gallon buckets of sealer (10 gallons total) for the job.
