Types of Asphalt Crack Sealers 1

Asphalt is a popular material for roads, driveways, and parking lots due to its durability and cost-effectiveness. However, over time, asphalt is prone to develop cracks, which can lead to further damage if not addressed promptly. That’s where crack sealers come in. Crack sealers are specially formulated materials that are used to fill and seal cracks in asphalt surfaces, preventing water penetration and extending the life of the pavement. In this article, we will explore the different types of asphalt crack sealers available in the market today.

Poured-In Sealers

Poured-in asphalt crack sealers are one of the most common types used for repairing cracks in asphalt surfaces. These sealers come in liquid form and are applied directly to the crack. The sealer penetrates the crack, filling it from the bottom to the top. Poured-in sealers have excellent bonding properties and provide a smooth, waterproof seal. They are easy to apply and are an ideal option for smaller cracks.

Rubberized Crack Sealers

Rubberized crack sealers are another popular type of sealers that are widely used for crack repair. These sealers are made by mixing asphalt with a rubberized polymer to create a flexible and durable patching material. Rubberized sealers are effective in filling both narrow and wide cracks, as the rubber content allows the sealer to expand and contract with temperature changes without cracking or losing adhesion. This type of sealer is particularly suitable for areas with high levels of seasonal temperature fluctuations.

Cold Pour Sealants

Cold pour sealants are formulated to be applied without heating. These sealants are ready-to-use and can be directly poured into the crack to fill and seal it. They are typically made from polymer-modified asphalt emulsion and offer good adhesion and flexibility. Cold pour sealants are designed to perform well in moderate climates and are an excellent choice for DIY enthusiasts as they are easy to apply without any specialized equipment or heating required.

Hot Applied Sealants

Hot applied sealants are commonly used for sealing larger cracks and joints in asphalt pavements. These sealers are heated in a melter or kettle and then applied using a pressure sealant applicator. Hot applied sealants are durable, long-lasting, and provide a strong bond with the pavement. They have excellent resistance to weathering, chemicals, and traffic loads, making them an ideal choice for high-traffic areas with heavy-duty requirements.

Colored Sealants

In addition to their functional benefits, sealants can also be used to enhance the aesthetics of asphalt surfaces. Colored sealants are available in a range of colors that can be matched to the existing pavement or used to create decorative patterns. These sealers not only provide crack sealing but also add a visually appealing touch to the pavement. Colored sealants are often used in areas where the appearance of the pavement is crucial, such as decorative walkways, parks, and driveways.


Choosing the right type of asphalt crack sealer is essential for effective crack repair and long-lasting pavement performance. Whether you opt for poured-in sealers, rubberized sealers, cold pour sealants, hot applied sealants, or colored sealants, make sure to consider the specific needs of your project and the climate conditions in your area. By using the appropriate crack sealer, you can protect and preserve your asphalt surfaces, minimizing further damage and extending the life of your pavement.
