Sealer Additives: The Pavement Sealcoating's Secret Weapon


Pavement sealcoating is an essential element in the maintenance of your asphalt. It not only enhances the appearance of your pavement but also provides protection against the elements, preventing water penetration, oxidation, and other damage. However, to truly maximize the benefits of sealcoating, professionals in the field know that the right mix of sealer additives is crucial. In this comprehensive guide, we will explore the world of sealcoating additives and their significant contributions to long-lasting, durable asphalt surfaces.


The Basics of Sealcoating Additives

When sealcoating your pavement, the base sealer you use is important, but it's the additives that can truly revolutionize the coating's effectiveness. Additives are materials added to the sealer mix to enhance durability, strength, and resistance to specific environmental stressors. These can include everything from rubber compounds for increased flexibility to sand for better traction. By customizing the sealer with the right additives, you can tailor it to the specific needs of your pavement and the climate in which it's situated.

Key Types of Sealcoating Additives

Several crucial additives enhance different properties of the sealcoating:

  • Latex: Introduces elasticity to the sealer, which is useful in areas with extreme temperature fluctuations.
  • Sand: Improves traction, especially on sloped surfaces.
  • Talc: Prevents sealers from sticking to surfaces, reducing scuffing from traffic.
  • Polymer fibers: Reinforce the sealer, reducing cracking and slowing the spread of existing cracks.
  • Drying accelerators: Shorten the curing time, ideal for projects with deadlines or in cooler weather.
  • Water: Sometimes, the most important additive is water, used to dilute concentrated sealers for the right consistency.

The Role of Each Additive in Pavement Health

To understand the value of sealcoating additives, it's important to explore how they contribute to the overall health of the pavement. Each type of additive provides a unique benefit, and when used in combination, they offer comprehensive protection against common asphalt issues.

Additives for Longevity and Durability

Polymer fibers and latex-based additives are the champions when it comes to durability. They provide much-needed reinforcement to the sealer, effectively reducing wear and tear on the pavement. By mitigating cracking and adding an element of elasticity, the sealer can withstand the trials of time and traffic more effectively.

Weather-Specific Additives

In areas with harsh winters or intense sun, additives can be tailored to the region's climate. Drying accelerators, for example, can ensure that sealant cures properly even in cooler temperatures, while UV inhibitors can help prevent sun damage in warmer climates.

Enhancing Aesthetics with Traction and Appearance

While not usually considered in the realm of additives, sand is often included specifically for aesthetic and functional purposes, providing a coarser finish that can improve traction and reduce the appearance of wear over time.

Optimizing Sealer Additives for Your Pavement

When selecting the right sealer and additives for your pavement, several factors must be considered, including the pavement area's use, its current condition, and the environmental conditions it faces.

Assessing Pavement Use

Highly trafficked areas may benefit from more durable, reinforced sealers with a higher ratio of latex or polymer fibers. In contrast, sealers with drying accelerators may be more suitable for parking lots that need to be back in service quickly.

Current Pavement Condition

The extent of existing damage on your pavement will dictate the type and amount of sealer additives needed. Cracked surfaces may require more polymer fiber reinforcement, while surfaces with minimal damage can benefit from a higher concentration of sand for added traction and aesthetic appeal.

Environmental Considerations

Areas with significant temperature fluctuations or exposure to high levels of UV radiation will require different sealer formulations. For example, using sealers with higher levels of UV inhibitors can significantly prolong the life of the pavement in sunny climates.

Choosing a Reliable Sealcoating Service

The expertise and experience of your sealcoating service providers can mean the difference between a pavement that stands the test of time and one that quickly deteriorates. When selecting a sealcoating professional, ensure they understand the importance of additives and have the knowledge to customize the application to your specific requirements.

Researching and Selecting the Right Contractor

Look for contractors with a history of successful projects similar to yours, and ask for references to validate their skill and reliability. A professional who takes the time to assess your pavement's specific needs and offers a tailored solution with the appropriate additives will be a valuable partner in your maintenance efforts.

The Benefits of Local Expertise

Pavement woes can be location-specific. Be it the intense sun of the West Coast, the bitter cold of the Midwest, or the regular downpours of the South, a local sealcoating expert can offer insights into the best practices and formulations for your region.

Wrap-Up and Next Steps

Sealcoating with the proper additives is a proactive way to extend the life of your pavement and protect your investment. By understanding the role of different sealcoating additives, and partnering with experienced professionals who can tailor the sealer to your pavement's specific needs, you're taking a crucial step towards a long-lasting and striking asphalt surface.


Whether you're a property manager looking to maintain pristine parking lots, a homeowner aiming to refresh your driveway, or a business owner maintaining the safety and aesthetic appeal of your entryway, the value of sealcoating with the right additives cannot be underestimated.
