How to Seal Asphalt Cracks

Asphalt cracks can be a nuisance, but with the right approach, they can be effectively sealed to prevent further damage. In this guide, I will walk you through the steps to seal asphalt cracks and extend the lifespan of your pavement, based on my perspective as an experienced professional.

Step 1: Prepare the Area

Before starting the crack sealing process, it’s important to prepare the area thoroughly. First, remove any loose debris or vegetation from the cracks. I think a wire brush or broom will come in handy for this task. Additionally, it seems to me that using a high-pressure air blower would be beneficial to clean out any remaining dirt or debris from the cracks. By ensuring a clean surface, you can promote better adhesion of the sealant.

Step 2: Choose the Right Sealant

Selecting the appropriate sealant is crucial for a successful crack sealing process. There are two main types of asphalt crack sealants available: cold pour sealants and hot pour sealants. From my perspective, cold pour sealants are easier to handle as they can be applied directly from the container. However, I would agree that hot pour sealants provide a more durable and long-lasting seal. Evaluate your specific needs and choose the sealant that best suits your project.

Step 3: Apply the Sealant

Once you have chosen the sealant, it’s time to apply it to the asphalt cracks. I feel that it’s important to start by cutting the tip of the sealant container to the desired width, usually around inch. Then, carefully pour the sealant into the cracks, ensuring that it fills the entire length and depth of each crack. You can use a caulking gun or pour pot for a controlled and consistent application. Be cautious not to overfill the cracks to avoid excessive buildup.

Step 4: Smooth and Level the Sealant

After applying the sealant, it’s crucial to smooth and level the surface. I would agree that this step is important for achieving an even and uniform appearance. Gently press the sealant into the cracks, making sure it adheres well to the surrounding asphalt. Use a putty knife or a trowel to smooth out any excess sealant and create a seamless finish. Allow the sealant to cure according to the manufacturer’s instructions.

Step 5: Maintain Regular Inspections

Sealing asphalt cracks is a proactive measure, but it’s important to stay vigilant with regular inspections and maintenance. Periodically check for any new cracks or signs of damage and address them promptly. It seems to me that by addressing minor issues early on, you can prevent more significant problems down the road.


I believe that sealing asphalt cracks is an essential maintenance task that can prolong the life of your pavement. By following the steps outlined in this guide, you can effectively seal cracks and prevent further deterioration. Remember to prepare the area, choose the right sealant, apply it carefully, smooth and level the surface, and maintain regular inspections. With proper maintenance, your asphalt pavement will remain in excellent condition for years to come.
