Can You Seal Coat a Gravel Driveway With Blacktop?

If you have a gravel driveway, you may be considering ways to improve its appearance and longevity. One option you may have come across is seal-coating the driveway with blacktop. But is this a good idea?

You can seal-coat a gravel driveway with blacktop. This process involves applying a thin coating of asphalt over the existing gravel surface. This layer of asphalt will act as a barrier to the elements, such as rain and snow, and will also help to bind the gravel together and reduce the potential for ruts and potholes.

Below, you’ll explore the pros and cons of sealing a gravel driveway with blacktop, as well as provide step-by-step instructions for those who decide to take on the project. So let’s dive in.

Can You Seal Coat a Gravel Driveway With Blacktop

Is Sealing A Gravel Driveway With Blacktop A Good Idea?

Many homeowners see blacktop as a realistic choice for increasing the aesthetic, longevity, and safety of their driveway. While some may believe that covering a gravel driveway with blacktop is a more expensive alternative than gravel, there are certain advantages to doing so. Here are the pros and cons of utilizing blacktop.


  • Improved appearance: A coat of blacktop can give a dull, gray gravel driveway a fresh, black appearance. This can enhance the curb appeal of your home and increase its value.
  • Increased durability: Blacktop sealant acts as a protective barrier for the gravel underneath, helping to prevent washouts and erosion. A sealed driveway is also less prone to potholes and other damage from vehicles.
  • Easier maintenance: Gravel driveways require regular maintenance, such as raking and filling in bare spots. A sealed driveway is much easier to keep clean and free of weeds.
  • Increased safety: A sealed driveway is smoother and less prone to puddles and potholes, which can be hazardous for pedestrians and vehicles.
  • Enhanced resistance to weather: Blacktop sealant provides some protection against the elements, helping to prevent damage from freezing and thawing, UV rays, and other environmental factors.


On the downside, there are a few considerations to keep in mind before deciding to seal a gravel driveway with blacktop:

  • Limited lifespan: Blacktop sealant does not last long. You can expect to reapply it every 2-3 years, depending on the condition of the driveway and the weather conditions in your area.
  • The difficulty of application: Applying seal coat to a gravel driveway can be challenging, as the rough surface requires extra prep work, and the sealant can be difficult to spread evenly. It’s important to follow the manufacturer’s instructions carefully and allow adequate drying time.

Overall, whether or not sealing a gravel driveway with blacktop is a good idea depends on your specific circumstances and goals. If you’re looking to improve the appearance of your driveway and increase its durability, seal coating may be a good option. However, if you’re on a tight budget or don’t mind the maintenance of a gravel driveway, it may not be worth the investment.

Is Sealing Travertine Tile Floor Similar to Seal Coating a Gravel Driveway With Blacktop?

Sealing a travertine tile floor is different from seal coating a gravel driveway with blacktop. The pros and cons of sealing a travertine tile floor include protecting against stains and moisture, but it can also alter the natural appearance of the stone. With a gravel driveway, seal coating can help with durability but may require frequent reapplication.

How To Seal A Gravel Driveway With Blacktop?

If you’ve decided to seal your gravel driveway with blacktop, it’s important to properly prepare the surface and follow the manufacturer’s instructions for the sealant you’re using. Here are the general steps you’ll need to take:

Step 1: Clean The Driveway

Remove any debris, weeds, and loose gravel from the surface of the driveway. Use a pressure washer to remove any dirt or stains. Allow the driveway to dry completely before proceeding.

Step 2: Fill In Any Holes Or Low Spots

Next, fill in any holes or low spots on the driveway using a gravel mix. This can be done by spreading the gravel evenly across the area and then compacting the gravel with a tamper or other heavy object.

It is important to ensure that the gravel is evenly distributed and firmly compacted for the best results. Additionally, it is important to choose a gravel mix that is best suited for the job and that can handle the weight of vehicles.

Step 3: Apply A Bonding Agent

Depending on the type of sealant you’re using, you may need to apply a bonding agent to the surface of the driveway. This helps the sealant adhere to the gravel and creates a smoother finish. Follow the manufacturer’s instructions for applying the bonding agent.

Step 4: Apply The Sealant

Use a squeegee or a seal coating brush to apply the sealant to the driveway. Be sure to cover the entire surface evenly and avoid creating puddles. Allow the sealant to dry according to the manufacturer’s instructions.

Step 5: Add A Second Coat

Depending on the condition of the driveway and the type of sealant you’re using, you may need to apply a second coat. If so, repeat steps 3 and 4.

Step 6: Allow The Sealant To Cure

Once the sealant has been applied, it’s important to allow it to fully cure before using the driveway. This can take anywhere from a few hours to a few days, depending on the weather and the sealant you’re using.

Maintenance And Upkeep Of A Sealed Gravel Driveway

A sealed gravel driveway requires less maintenance than an unsealed driveway, but it’s still important to take care of it to ensure that it stays in good condition. Here are a few tips for maintaining a sealed gravel driveway:

Sweep Regularly

Use a broom or a leaf blower to remove any debris or leaves from the surface of the driveway. This will help prevent stains and protect the sealant from getting damaged.

Repair Cracks And Holes Promptly

If you notice any cracks or holes in the sealant, repair them as soon as possible. Use a crack filler or patching compound specifically designed for blacktop surfaces.

Reapply Sealant As Needed

Blacktop sealant does not last forever and will eventually need to be reapplied. Keep an eye on the condition of the sealant and reapply it every 2-3 years or as needed.

Avoid Spilling Oil Or Other Chemicals

Oil and other chemicals can cause stains and damage the sealant. Be sure to clean up any spills promptly and avoid parking vehicles that leak oil on the driveway.


Sealing a gravel driveway with a blacktop can provide a number of benefits, including improved appearance, increased durability, and easier maintenance. However, it’s important to weigh the pros and cons before making a decision, as seal coating is a significant investment that requires regular upkeep.

If you do decide to seal your gravel driveway with a blacktop, be sure to properly prepare the surface and follow the manufacturer’s instructions for the sealant you’re using. Proper maintenance, such as sweeping and repairing cracks and holes, can help extend the life of the sealant and protect your investment. Carefully consider the costs and ongoing maintenance before making a decision.
