Different Types of Asphalt Sealants for Cracks 1

Why Do Asphalt Cracks Occur?

Asphalt surfaces are commonly used for roads, parking areas, playgrounds, and other outdoor spaces. Over time, they are exposed to natural elements, such as extreme temperatures, rainfall, and sunlight, causing cracks that create an unsightly appearance and may result in further damage if left unaddressed. Cracks can occur due to the natural aging of the material, heavy usage, or fluctuations in temperature. Sealants are essential for repairing cracks in asphalt surfaces to prevent water penetration and further damage.

Types of Asphalt Sealants for Cracks

There are different types of asphalt sealants for cracks, each with its own set of benefits.

  • Cold-pour sealants
  • Hot-applied sealants
  • Acrylic sealants
  • Polyurethane sealants
  • Cold-Pour Sealants

    Cold-pour sealants are easy to apply and do not require heating or special equipment. They come in liquid form and can be applied directly to the crack using a pour spout or a squeeze bottle. Once applied, they dry and form a flexible rubber-like substance that seals the crack, preventing water penetration and further damage. Cold-pour sealants have a lower viscosity than hot-applied sealants, which makes them ideal for narrow and small cracks but they have a shorter lifespan compared to the other types.

    Hot-Applied Sealants

    Hot-applied sealants are mostly used for larger cracks and larger areas. They require heating to a temperature of 300 to 350°F before being applied to the crack. The melted sealant is then poured into the crack, filling it completely. Once the sealant cools down, it hardens, providing a durable seal for the crack. Hot-applied sealants can last up to ten years, making them a popular choice for larger cracks that need long-term protection.

    Acrylic Sealants

    Acrylic sealants are based on water and come in different colors, making them ideal for coloring asphalt surfaces to match the surrounding environment. They are applied using a small roller, paintbrush, or squeeze bottle. Once dry, they form a waterproof coating on the surface, protecting it from further damage. Acrylic sealants are mainly used for cosmetic purposes but can also help fill small cracks.

    Polyurethane Sealants

    Polyurethane sealants are known for being highly flexible and resistant to wear and tear. They are ideal for sealing cracks that are prone to expansion and contraction due to fluctuations in temperature. Polyurethane sealants come in two types: one-part and two-part. One-part sealants can be applied directly to the surface using a squeeze bottle, and they cure over time when exposed to atmospheric moisture. On the other hand, two-part sealants require mixing before being applied and have a shorter curing time. Polyurethane sealants are long-lasting and can remain effective for up to 25 years.


    Asphalt sealants for cracks are essential for maintaining the longevity of asphalt surfaces and preventing further damage. The right sealant depends on the type of crack and its severity. Cold-pour and hot-applied sealants are the two most commonly used types, whereas acrylic and polyurethane sealants are better suited for cosmetic purposes. It is recommended to work with a professional to assess the damage and select the appropriate asphalt sealant for you to ensure your asphalt surface stays in good condition for years to come.
