What is Asphalt Sealcoating?

Before we dive into the factors influencing sealcoating, let's first understand what asphalt sealcoating entails. Sealcoating is a protective layer applied to asphalt pavements to shield them from damage caused by weather, chemicals, and regular wear and tear. This process involves applying a liquid protective coating over the existing pavement, which cures to form a tough, resilient barrier.

The benefits of sealcoating are numerous. It extends the life of the pavement, enhances its appearance by restoring the dark black color, and protects against water penetration, oxidation, and UV rays.
 

Factors Affecting Asphalt Sealcoating

1. Climate Conditions

Polk County experiences a subtropical climate characterized by hot, humid summers and mild winters. These conditions present unique challenges for asphalt maintenance:

• Heat and UV Exposure: Prolonged exposure to high temperatures and UV rays can lead to the oxidation of asphalt, causing it to become brittle and prone to cracking. Sealcoating acts as a sunscreen for your pavement, providing a protective layer against these elements.
• Rain and Humidity: Frequent rain and high humidity levels can accelerate the degradation of unprotected asphalt surfaces. Sealcoating creates a waterproof barrier that prevents water infiltration, reducing the risk of potholes and other moisture-related damages.

2. Traffic Loads

The level and type of traffic your pavement endures significantly impact its longevity and the effectiveness of sealcoating:

• Heavy Traffic Areas: Parking lots, driveways, and roads that experience heavy traffic loads are more susceptible to wear and tear. Sealcoating provides an extra layer of protection that helps distribute the weight more evenly and reduces surface stress.
• Type of Vehicles: The types of vehicles using the pavement also matter. For instance, areas frequently used by heavy trucks may require more frequent sealcoating to maintain optimal protection.

3. Quality of Materials

Not all sealcoating materials are created equal, and the choice of materials can affect the outcome and durability of the sealcoating process:

• Sealant Type: Commonly used sealants include coal tar, asphalt emulsion, and acrylics. Each has its pros and cons in terms of durability, environmental impact, and cost. Choosing the right sealant is crucial for achieving the best results.
• Additives and Fillers: High-quality sealcoating applications often include additives such as polymers and fillers that enhance the sealant's performance, including its resistance to oil, gas, and salt.

4. Surface Preparation

Proper surface preparation is key to a successful sealcoating job. This includes cleaning the pavement thoroughly, repairing existing cracks, and ensuring a smooth surface for the sealant to adhere to:

• Cleaning: Removing dirt, debris, and oil stains is essential for proper adhesion of the sealcoat. Pressure washing and specialized cleaning agents may be used for this purpose.
• Crack Filling and Repairs: Prior to sealcoating, any cracks or potholes should be filled and repaired. Neglecting this step can lead to sealcoat failure and further damage to the pavement.
   

The Sealcoating Process

Understanding the sealcoating process can help you appreciate its importance and the precision required to achieve quality results:

1. Inspection and Evaluation

A professional team will assess the condition of your asphalt and recommend the appropriate sealcoating schedule and materials.

2. Surface Cleaning and Preparation

The pavement is cleared of all debris, oil stains, and vegetation to ensure a clean surface for sealcoating.

3. Crack Filling and Repairs

All visible cracks and potholes are filled, ensuring a smooth surface for the sealant application.

4. Sealant Application

The sealant is applied using brushes, squeegees, or spray equipment, depending on the size of the area and specific requirements.

5. Curing Time

After application, the sealcoat needs time to cure. This typically takes 24 to 48 hours, during which the pavement should remain undisturbed.
 

Maintenance Tips for Long-lasting Sealcoating

To maximize the lifespan of your newly sealcoated pavement, consider the following maintenance tips:

• Regular Cleaning: Keep your pavement clean by regularly sweeping and washing off debris and spills that can degrade the sealcoat.
• Prompt Repairs: Address cracks and damages promptly to prevent water infiltration and further deterioration.
• Resealing Schedule: Depending on traffic and weather conditions, plan to reseal your pavement every 2 to 3 years to maintain its protective barrier.
