How to seal an asphalt driveway?

Before you decide to seal an asphalt driveway, it’s important to know a few things. Whether you should use a spray or brush, how often to apply sealer, and how much it will cost are all factors to consider. You may also want to consider the appearance of the surface after the sealer has been applied. If the surface peels up and shows uneven wear, the asphalt seal may be damaged. This can lead to flakes of material falling everywhere, increasing the amount of moisture exposure in the surface.

Fill-and-seal products

A fill-and-seal product is a great way to seal an asphalt driveway. It can be applied to cracks and potholes of up to 1/8″ in width, and will leave a textured, nonskid surface. However, cracks and potholes larger than this should be repaired with an asphalt patching product. These products are DIY-friendly and are often available in low-VOC formulations. They last up to 3 years and will not need to be reapplied often.

The most common fill-and-seal product for asphalt driveways contains latex or other polymer, which makes it flexible enough to adhere to the surface of the driveway. Most of these formulas also contain sand, which improves traction. They can be sprayed, broomed, or spread with a squeegee. Another type of sealer for asphalt driveways is a concrete sealer, which is a film-forming acrylic resin. It is available in solvent and water-based formulas. It is best to use solvent-based sealers, rather than styrene acrylics, which can cause the sealer to flake off the surface.

Costs vary, so you may want to shop around before deciding on a specific product. Generally, the higher quality products have a longer warranty. However, some of the lower-grade products do not come with warranties. You can ask the manufacturer about their warranty policies, but you should understand that these warranties are prorated. You will also need to consider the condition of your driveway and the size of the cracks before making a decision.

Most contractors charge by the square foot. Hence, the cost of seal coating an asphalt driveway can range anywhere from $1.21 to $1.53 per square foot. In addition, if you decide to hire a professional, you should be prepared to spend $575 to $1,150 per thousand square feet. However, you should consider that some contractors require a minimum fee before providing a driveway seal coating.

Before applying fill-and-seal products to seal your asphalt driveway, you should make sure that it is clean and dry. Using a clean driveway will ensure that the sealcoat will last a long time.

Brush or spray

When it comes to applying sealant on asphalt driveways, there are two common methods: brush and spray. Spraying is the more popular method and provides a more even coating. Brush application relies heavily on manual techniques and the operator is responsible for spreading the sealant evenly across the surface.

There are advantages and disadvantages to both methods. The disadvantage of brushing is that it leaves uneven coating, which can make the sealant harder to cure. A sealant that is sprayed evenly ensures that the sealer covers the surface evenly and quickly. Homeowners can apply sealer themselves with a broom or squeegee, but a sprayer is recommended for businesses and contractors.

After cleaning and applying sealer, you should let the surface dry for 24 hours. During this time, you must avoid driving on the driveway. You should also ensure that the weather remains above 50 degrees F. Otherwise, the sealer will dry too quickly. Moreover, heavy rain can wash away your hard work. If you don’t have a time to wait for two days, try applying a driveway cleaner with a garden hose or power washer. If you don’t have the time to wait for the sealer to dry, use a stiff-bristle push broom to scrub the surface.

Although the use of sealant isn’t a permanent solution, it will protect your asphalt driveway from oxidation. As the sealant wears off, you need to apply it more frequently to keep it looking as good as new. Sealing is an important step in asphalt maintenance.

Before applying an asphalt sealcoat, make sure you know the difference between a brush and a spray. Not all contractors apply the same products and apply them differently. Some use asphalt emulsion while others use coal tar emulsion. These two products are both toxic and are banned in certain areas of Michigan. If you’re unsure about the difference, ask a contractor who’s experienced and educated in seal coating.

The best time to apply an asphalt seal coat is during the spring or summer months, when temperatures are over 50 degrees. After applying sealant, you should wait for 72 hours for it to dry properly. Then, you should wait 3 to five days before driving on a fresh driveway.

When to apply

The decision about when to seal an asphalt driveway depends on a number of factors. Asphalt surfaces begin to deteriorate as soon as they’re laid, so it’s important to pay attention to existing cracks and damage before applying a sealant. A professional can evaluate your driveway and determine whether it needs to be sealed or resurfaced.

The best time to seal an asphalt driveway is in the spring or summer when the temperature begins to drop. In addition to preventing cracks, you should inspect the driveway for cracks and stains before applying a sealant. If you find any oil or grease stains, clean them out with soapy water. If the stains are more stubborn, use a degreaser. Cracks can be repaired with crack fillers, and larger cracks can be filled with asphalt repair caulk. This process can take up to six or eight hours.

Once your asphalt driveway has undergone repair and is ready for sealcoating, make sure you wait for two days of dry weather. The temperature should be at least 50 degrees Fahrenheit throughout the day and night before applying the sealer. Otherwise, the sealer will be unable to set, and it will wash away in heavy rain.

Depending on the climate, asphalt driveways should be sealed every three to five years. However, if the driveway is new, you shouldn’t apply sealant right away because it may trap oils in the new surface, which makes it too soft. The best time to apply a sealant is when temperatures are in the 50s to ninety degrees Fahrenheit, and there hasn’t been any rain for at least three days.

If your asphalt driveway is brand new, you should wait about three months before applying a seal coat. After this, it’s important to allow it to fully cure for three months. However, if it was installed in the fall, you should wait six to nine months before applying a seal coat. Applying a seal coat will last longer and will provide a better value for your money.

While it’s tempting to apply a thick coat of sealer, it is important to avoid overdoing it. Too much sealer will cause premature cracking, which will decrease the lifespan of your driveway. To prevent this problem, some paving contractors thin the sealant and water it down before application.


There are a number of factors that can affect the cost of sealing an asphalt driveway. The width and length of your driveway are the most important, as larger surfaces require more sealant. In most cases, a single coat of sealant is sufficient to cover 480 to 650 square feet of asphalt. In addition, the age of your driveway can affect the overall cost. Some driveways may need additional repairs or upgrades before they can be sealed.

There are three types of sealants, each of which has its own pros and cons. Oil-based sealers are typically less expensive and do not last as long. But they can be difficult to work with and only fill small cracks. You can expect to spend about $0.15 to $0.20 per square foot on oil-based sealer. Acrylic sealants are better than coal tar, but are more expensive. Coal tar has a high VOC content and can cause soil and groundwater contamination. Because of this, they are banned in many areas.

Professional sealants use industrial-grade sealant and special tools that allow them to apply the material precisely. In addition, they have extensive industry knowledge and experience. The average cost of sealing an asphalt driveway will depend on several factors. The size and shape of your driveway will affect how much you spend on the service. However, there are several things you can do to reduce the cost of the work.

The first step in the process of sealing an asphalt driveway is to clean it and fill any cracks or eroded areas. If the cracks are deep and the material is not level, you will need to apply a trowel-grade crack filler. Once the crack filler is dry, you can then apply the sealant mix. Afterwards, you must squeegee the mixture using long strokes.

The price for sealing an asphalt driveway will vary based on many factors, including the size of your driveway and the number of cracks. Most sealing professionals price their services by the square foot, so determining the size of your driveway will help you determine what materials you will need for the job.
