If you’re frustrated by your asphalt driveway’s appearance, you aren’t the only person who’s tired of seeing cracks, potholes, or oil stains spread across a once-smooth surface. Asphalt driveways are sleek and simple, but over time they can break down and pose plenty of problems — and the worse these driveways get, the more unattractive they can make your property appear. To repair or prevent common asphalt driveway woes, you need to protect it with a sealer.
Asphalt driveway sealers smooth over a driveway’s surface, covering it in a protective layer that prevents issues like cracks, stains, and more caused by chemicals, harsh sunlight, and even temperature changes. Sealing your driveway is easy, but it requires the right asphalt driveway sealer to do the job well. Check out our picks for the best asphalt driveway sealers right here.

Benefits of Asphalt Driveway Sealers
- Long-lasting durability. An asphalt driveway sealer won’t merely protect your driveway after it’s applied. These sealing products can last many seasons and even many years, with some offering durability up to five years. Additionally, the durability a sealer provides will keep your driveway looking pristine for longer, protecting it against common issues.
- Weather and water protection. Most asphalt driveway sealers protect against the two biggest issues driveways face: water and changing weather. Rain, snow and even sunlight can all cause problems like cracks and, over time, potholes. Sealers will ensure your driveway can handle everything that might happen outdoors in each season year-round.
- Increased curb appeal. Applying a protective sealer to your driveway can help your home look its best long after you’ve purchased it. Whether you simply want to keep your house looking great or you’re hoping to sell it, a protected and pristine driveway will enhance your home’s curb appeal, making it more attractive and good-looking.
Types of Asphalt Driveway Sealers
A plain asphalt driveway sealer is the simplest, most basic kind of sealer you’ll find. It’s a thick black liquid that’s made with either coal tar or asphalt cement, and you slick it right on top of your driveway with a paint roller. Plain sealers don’t contain sand, so they’re best used on driveways that have very little damage since they cannot fill or patch holes and cracks.
Asphalt-based sealers are highly durable. They’re made with a blend of asphalt cement and other protective materials, and they’re quite popular for those who already have asphalt driveways because they offer a seamless materials blend. This kind of driveway sealer is also very long-lasting: a single coat can last as long as five to six years.
Coal Tar Sealer
Coal tar asphalt driveway sealer is considered the standard for asphalt — in some places, that is. The preferred choice for both asphalt driveways and streets for many years, coal tar sealer is made from sticky coal tar. It can last for up to five years on a driveway. However, this kind of sealer has fallen out of use in many cities and states because it contains high levels of volatile organic compounds, and it’s even banned in some places.
Fill and Seal Products
Fill and seal products are dual-purpose sealers. They can be made with a range of different materials and types of sealants, and they always include sand or a sand-like ingredient that can fill in cracks and holes. You can use these products to both seal and protect your driveway and repair holes, cracks, and other problems. It’s a great option if you have small cracks or potholes, as it’ll save you time and money.

Asphalt Driveway Sealer Pricing
- Under $50: You can find plenty of budget-friendly fill and seal products priced at less than $50. Sold in smaller tubs and tubes, these sealers are great for first-time use or fixing small areas of your driveway.
- $50 to $200: Most asphalt driveway sealers fall between $50 and $200 in price. You’ll find both low and high-quality products within this range—some tougher and more capable than others.
- $200 to $300: The most premium and highly durable sealer products run in this price range, and they tend to offer a wealth of benefits. These sealers are among the best available, but they’ll cost you.
Attractive Surface Finish
While an asphalt driveway sealer is all about protection and prevention, applying one of these products can make your driveway look even better. Many sealers include specialty effects or finishes, like sheen, a satin-smooth appearance, or varying gloss levels. Some sealers are even colored if you want to spice up your driveway even more. Opting for a driveway sealer that offers an attractive surface finish can really enhance your driveway’s curb appeal.
No one wants to struggle with an asphalt driveway sealer. If you choose a product that’s difficult to apply, you’ll find yourself frustrated in no time at all. Opt for a product that’s easy to pour, spread, and fully apply, and you’ll be even happier with the final result. Look for a sealer that can spread with a simple paint roller, pour spout, or spray to make your work a whole lot easier.
You probably don’t think about flexibility when you think about your driveway, but using an asphalt driveway sealer that offers flexibility is essential. Flexible sealers can bend, flex, and adapt as your driveway undergoes temperature changes — like freezing construction and warm weather expansion — and bears the weight of vehicles. Flexibility can increase a sealer’s ability to adapt and last.
- Water is a Huge Issue. When you’re choosing a driveway sealer, make sure you consider waterproof versus water repellent options. Waterproofing offers more protection, but a water repellent sealer should be perfectly fine in most climates. Because water is such a significant problem for asphalt driveways, you want to make sure you’re preventing as many cracks and potholes as possible.
- Don’t Forget to Prep Your Driveway. Before you can apply any kind or type of sealer to your asphalt driveway, you’ll need to do a bit of prep. You should only apply sealer on a clean surface, so it’s a good idea to pressure wash your driveway first. Then, if you have any large cracks or potholes bigger than 1/8 inch wide, you’ll want to fill and repair them.
- Leave Your Driveway Alone After Sealing It. Once you’ve applied any kind of sealer to your asphalt driveway, you’ll need to be prepared to stay away from it for a while. Typically, you’ll need to keep it free of vehicles and any foot traffic for about 24 hours to let the sealer cure. It’s also a good idea to do the sealing work on a day around 55 to 60 degrees in temperature to prevent potential issues.
Best Asphalt Driveway Sealers Reviews & Recommendations 2021
- Two thin coats of sealer are typically needed to cover and protect your driveway completely, so make sure you buy enough to cover your driveway’s area two times.
- Most asphalt driveway sealers can cure in just a few hours, but that doesn’t mean you can drive or walk on it—you’ll need to wait up to 48 hours just to be safe.
- To ensure your sealer actually sticks, don’t apply it if rain is anticipated the day before or after you plan to apply the sealer.
- Fog and morning dew can affect your sealer, and they can even wash it away unexpectedly. So, make sure you plan ahead if these are common in your area.
