What is Asphalt Sealcoating?

Benefits of Asphalt Sealcoating for parking lots

Asphalt sealcoating involves applying a thin layer of an asphalt emulsion sealer to an asphalt parking lot. Asphalt sealcoat does not adhere to concrete surfaces for a prolonged period of time and offers no benefits to concrete.

This protective coating helps prevent damage from environmental factors such as:

  • UV rays
  • Water
  • Grease
  • Snow
  • Chemicals, including oil and gas spills

This ensures that your asphalt surfaces remain intact and durable. This layer significantly extends the life of your asphalt pavement, keeping your asphalt driveway and parking lots in excellent condition for years.

One of the primary functions of sealcoating is to preserve the integrity of asphalt pavement. Without this protective layer, asphalt surfaces can quickly deteriorate due to exposure to the elements. For instance, constant exposure to sunlight can cause the asphalt to oxidize, leading to brittleness and cracks. Additionally, water infiltration can weaken the structural foundation of the pavement, causing potholes and other significant damage.

In summary, asphalt sealcoating is a crucial step in pavement maintenance. It not only protects the surface from damage but also enhances its appearance, making it look fresher and newer. Incorporating sealcoating into your routine maintenance saves on costly repairs and extends the life of your asphalt surfaces.

Key Ingredients in Asphalt Sealcoating

Benefits of Asphalt Sealcoating

Asphalt sealcoating is composed of several key ingredients, each playing a vital role in ensuring the protective layer is effective and durable. The main components include asphalt emulsion, additives, and aggregates.

Together, these ingredients form a high-quality sealcoat mix that offers long-lasting protection for asphalt surfaces.

Asphalt Emulsion

Asphalt emulsion is the backbone of the sealcoating process. It forms the base for a protective layer over asphalt surfaces. The primary ingredient in asphalt emulsion-based sealcoating is asphalt cement, which binds the aggregates and other additives together, forming a cohesive and durable asphalt emulsion sealer.

Additives

Additives in asphalt sealers play a crucial role in enhancing the performance characteristics of the sealcoat. Additives enhance flexibility, water resistance, and drying speed, making the sealant more effective against environmental challenges.

Each additive uniquely contributes to the mixture, ensuring the sealcoat withstands various weather conditions and chemical spills.

Aggregates

Aggregates, including sand, are essential components of sealcoat mixtures. They enhance the mechanical properties of the sealcoat, contributing to its strength and stability.

and is the most common aggregate in asphalt sealcoating, which adds unique benefits to the formulation.

How Does Asphalt Sealcoating Work?

Sealcoating works by creating a protective barrier on the asphalt surface, preventing water infiltration, which is a major threat to the pavement’s structure. When applied, the sealcoat makes the asphalt surface impermeable, effectively blocking water from penetrating and causing foundation damage. This impermeability is crucial in maintaining the structural integrity of the asphalt pavement.

In addition to preventing water damage, sealcoating slows the oxidation of asphalt, which otherwise leads to brittleness and cracking over time. It also helps bind loose aggregate and fine particles within the asphalt, maintaining surface integrity and overall durability.

Understanding how sealcoating works helps appreciate its importance in preserving your asphalt surfaces.

Benefits of Asphalt Sealcoating

cracks in asphalt

Asphalt sealcoating offers benefits beyond aesthetics. One of the most significant advantages is its ability to block out harmful UV rays, reducing the oxidation rate of asphalt. This extra protection against UV damage can prevent the asphalt from becoming brittle and cracking over time.

Another major benefit is the prevention of cracks and potholes, which can lead to expensive repairs if left unaddressed. Neglecting asphalt cracks can result in potholes, significantly increasing repair costs. The cost of sealcoating is minimal compared to repairing or replacing damaged asphalt, making it a cost-effective solution for pavement maintenance.

Furthermore, sealcoating can extend the lifespan of asphalt surfaces, with properly sealed pavement lasting up to 30 years. Applying a protective sealer regularly shields asphalt from water damage and chemical spills, keeping it in top condition. Incorporating aggregates in sealcoating also improves durability and strength, making the asphalt look fresher and newer.

Cost of Sealcoating Your Parking Lot

The cost of sealcoating a parking lot in Michigan can vary due to several factors. Typically, the cost range for sealcoating is between $0.15 and $0.35 per square foot. The size of the parking lot is a significant factor, as contractors generally charge by the square foot. In Michigan, the cost may be influenced by the local climate, which can affect the frequency and type of maintenance required.

Other factors that influence the cost include the type of sealant used and the condition of the asphalt. Using a thicker sealant can lead to less coverage per unit, increasing the overall cost.  Keep in mind that when sealcoating your parking lot, it is just as important to complete crack sealing. Crack sealing is the process of cleaning out the cracks and installing a hot rubber that bonds to the walls of the cracks. This prevents water penetration into the foundation.

Geographical location within Michigan can also impact the cost of sealcoating. Prices can vary between urban and rural areas.Choosing eco-friendly sealant options, which tend to be more expensive, may also affect the total cost.

When to Apply Asphalt Sealcoating

The optimal time to apply asphalt sealcoating is when both air and ground temperatures are at least 50 degrees Fahrenheit and rising, with humidity below 50 percent. In regions like Michigan, the sealcoating season typically starts in late May or early June and ends by September 30. Sealcoating should only be done when the asphalt temperature is above 50 degrees Fahrenheit.

Regular resealing, typically every three years, is advised to combat the effects of sunlight and rainfall, which can degrade the sealcoat. It’s also important to avoid rain for at least 12 hours following the application of sealcoating to ensure proper curing.

Turning off sprinklers a day before and after sealcoating helps prevent water from interfering with the sealant.

Steps to Properly Sealcoat an Asphalt Surface

Properly sealcoating an asphalt surface involves several crucial steps, including cleaning the surface, repairing cracks and holes, and applying the seal coat using the right techniques. Each step is essential to ensure the sealcoat adheres properly and provides long-lasting protection.
