Understanding the Importance of Asphalt Crack Sealer

Asphalt is a commonly used material for pavement, providing durability and a smooth surface for vehicles and pedestrians. However, over time, cracks can develop due to fluctuations in temperature, heavy traffic, and other external factors. These cracks not only detract from the appearance of the pavement but can also lead to more severe structural issues if left untreated.

One effective way to address these cracks is through the use of asphalt crack sealer. This material is specifically designed to fill in and seal cracks, preventing water from seeping into the pavement and causing further damage.

Preparing the Surface

Before applying asphalt crack sealer, it is crucial to properly prepare the surface. The first step is to clean the cracks and remove any debris or vegetation that may be present. This can be done using a wire brush or a high-pressure air hose. It is important to ensure that the cracks are completely free of any loose material.

After cleaning the cracks, it is advisable to widen them slightly using a crack router or a crack saw. This helps create a better surface for the crack sealer to adhere to and ensures a more effective seal. Additionally, wider cracks allow for better penetration of the sealer, increasing its longevity.

Choosing the Right Crack Sealer

There are different types of asphalt crack sealers available on the market, each with its own unique properties and application methods. It is important to choose a crack sealer that is compatible with the type of pavement being repaired and the climate conditions in the area.

Some commonly used crack sealers include hot-pour sealants and cold-pour sealants. Hot-pour sealants are heated to a temperature where they become liquid and are then poured into the cracks. They tend to have better adhesion and durability. Cold-pour sealants, on the other hand, are already in liquid form and can be applied directly from the container. They are easier to handle and are often used for smaller cracks.

Application Techniques

Once the surface is prepared and the appropriate crack sealer is selected, it is time to apply the sealer. Here are some key techniques to ensure a proper application:

1. Begin by pouring the crack sealer into a pouring pot or a similar container that allows for easy pouring.

2. Carefully pour the sealer into the crack, making sure to fill it from the bottom up. Avoid overfilling as it can lead to a poor-quality seal.

3. Use a squeegee or a broom to spread the sealer evenly across the cracks. This helps to ensure that the sealer is properly distributed and that there are no gaps or voids.

4. For larger cracks, a squeegee may not be sufficient. In such cases, a trowel or a putty knife can be used to spread the sealer and create a smooth, uniform surface.

5. Allow the sealer to dry and cure according to the manufacturer’s instructions. This typically takes a few hours, but it is recommended to avoid any traffic on the repaired area for at least 24 hours.

6. After the sealer has cured, it is advisable to apply a sealcoat over the entire pavement surface. This helps to protect the asphalt from further deterioration and extends its lifespan.

Maintenance and Longevity

Proper maintenance is crucial to ensure the longevity of the asphalt crack sealer. Regular inspections should be conducted to identify any new cracks or signs of deterioration. Promptly addressing these issues can prevent them from worsening and requiring more extensive repairs.

In addition to regular inspections, it is important to keep the pavement clean and free of debris, as well as to address any drainage issues that may lead to water pooling on the surface. Regularly applying a sealcoat can also help to protect the pavement and prolong the effectiveness of the crack sealer.


Applying asphalt crack sealer is an essential step in maintaining the integrity and appearance of asphalt pavement. By understanding the importance of crack sealer, properly preparing the surface, choosing the right sealer, and employing proper application techniques, it is possible to effectively repair and prevent further damage to the pavement. With regular maintenance and proper care, the crack sealer can provide long-lasting protection and contribute to the durability of the pavement.
