Are you looking to learn more about sealcoating services and what they can do for your paved surfaces? Join %COMPANY% as we discuss the importance of sealcoating, how it protects your asphalt investment, and the best steps to get a top-quality sealcoat.

Understanding Sealcoating

Before we explore its benefits, let’s clarify what sealcoating entails. Sealcoating is the process of applying a protective layer of asphalt-based emulsion or coal tar pitch to the surface of asphalt pavement. Sealcoating is typically made of either asphalt-based emulsion or coal tar pitch, along with various additives for improved performance.

Types of Sealcoating

Asphalt-based sealcoating is commonly used for residential driveways and low-traffic areas. This type of sealcoating is formed using asphalt binder, water, and emulsifying agents. This type of sealcoating is most commonly used for residential driveways and low-traffic areas.

Coal tar pitch sealcoating is derived from coal tar, a byproduct of the coking process in the production of coke or coal gas. This form of sealcoating has been used for decades and is known for its durability, resistance to chemicals, and ability to withstand harsh weather conditions. It’s often preferred for high-traffic areas such as commercial parking lots and roadways.

Benefits of Sealcoating

Asphalt sealants act as a barrier, shielding your asphalt from harmful elements such as:

  • Water
  • UV rays
  • Oil
  • Gasoline
  • Harsh weather conditions
  • …and more

By sealing the surface, sealcoating helps prevent oxidation, cracking, and deterioration, ultimately prolonging the life of the asphalt.

Asphalt Sealants Offer Protection Against Environmental Damage

One of the primary reasons for asphalt deterioration is exposure to the elements. Rainwater, snow, and ice can penetrate the asphalt surface, leading to moisture damage and weakening the structural integrity of the pavement. Meanwhile, UV rays from the sun can accelerate the oxidation process, causing the asphalt to become brittle and prone to cracking.

Thanks to sealcoating, you won’t have to worry about these issues. Sealcoating forms a waterproof barrier that repels water and blocks UV radiation, preventing moisture infiltration and UV damage.

Protection Against Pavement Cracks

Cracks are a common issue with asphalt surfaces, especially in regions with fluctuating temperatures and freeze-thaw cycles. When water seeps into cracks and freezes, it expands, causing the asphalt to crack further. Over time, untreated cracks can lead to potholes and extensive pavement damage.

Can Sealants Repair Cracks?

Sealcoating fills in minor cracks (less than 1/8 of an inch wide) and seals the surface, preventing water from infiltrating the asphalt and exacerbating existing damage. Sealcoating also slows down the oxidation process, preserving the flexibility and durability of the asphalt.

You Can Enhance Curb Appeal With Asphalt Coatings

Beyond its protective benefits, sealcoating also enhances the aesthetic appeal of asphalt surfaces. Freshly coated pavement has a smooth, uniform appearance with a rich, deep black color that revitalizes the overall look of the property.

Whether a residential driveway, commercial parking lot, or community walkway, sealcoating gives asphalt a fresh, well-maintained appearance that enhances curb appeal and leaves a positive impression on visitors and customers.

Keep the Costly Driveway Repairs Away

Driveway repairs can potentially cost anywhere from a few hundred dollars for minor fixes to $5,000 or more for extensive damage and full replacements. Proper maintenance and addressing problems early can help keep costs at the lower end of this range. One of the best things you can do is invest in a well-applied driveway sealcoat.

Studies have shown that properly maintained asphalt surfaces can last up to twice as long as untreated pavement, making sealcoating a cost-effective strategy for preserving your asphalt investment. By investing in regular sealcoating, you can significantly extend the life of asphalt pavement, saving substantial costs in the long run.

Asphalt Sealcoating Ensures Safer Surfaces

When you want safer paved surfaces, you need to invest in asphalt sealcoating services. Cracked, deteriorated asphalt surfaces pose safety hazards to pedestrians, drivers, and cyclists, increasing the likelihood of slips, trips, and falls, as well as vehicle damage.

Sealcoating helps maintain a smooth, even surface that reduces the risk of accidents and injuries, protecting both property owners and visitors from potential liabilities.

Applying Your Sealcoating

Sealcoating is applied by professional contractors using specialized equipment, such as spray systems. Before applying the sealant, the pavement must be thoroughly cleaned and prepared to ensure proper adhesion and longevity of the sealcoat.

How Long Does the Sealcoating Process Take?

The time it takes to sealcoat a driveway or parking lot can vary depending on several factors, including the size of the area, weather conditions, and the specific sealcoating product used. There is also some prep work that needs to be done.

After the pavement has been cleaned and repaired, it’s important to allow sufficient time for the surface to dry completely before applying the sealcoat. This typically involves waiting at least 24 to 48 hours, depending on weather conditions such as temperature and humidity.

For a standard residential driveway, sealcoating application may take a few hours to complete. Larger parking lots or commercial properties may require more time. As for the curing times, they’re dependent on numerous factors as well.

Should You Re-Apply Sealcoating to Pavement?

Sealcoating offers many benefits, but you won’t be able to reap these benefits forever. Like all sealants, they fall victim to wear and tear over time.

The lifespan of sealcoating on driveways, parking lots, and walkways typically ranges from two to five years, depending on factors such as weather conditions, traffic volume, maintenance practices, and the quality of the sealcoating product applied.
