How to Choose the Right Sealcoating for the Summer in Memphis
Summertime in Memphis brings scorching heat, high humidity, and intense UV rays that can take a toll on asphalt surfaces. Whether you’re a homeowner protecting your driveway or a business owner maintaining a parking lot, selecting the right sealcoating solution is essential for preserving your pavement and avoiding costly repairs. Understanding the climate, types of sealcoating available, and best practices in application will help you make an informed decision that ensures durability and longevity. In this blog, we’ll walk through the considerations you need to take into account to choose the most suitable sealcoating for your asphalt during the hot Memphis summer.
Understanding the Memphis Climate and Its Impact on Asphalt
Memphis summers are known for their extreme temperatures, often soaring into the upper 90s with high humidity levels. These environmental conditions create a perfect storm for asphalt degradation. UV radiation breaks down the binder that holds the aggregate together in asphalt, leading to surface oxidation, cracking, and erosion. High heat softens the surface, making it more vulnerable to wear from vehicle traffic and footfall. Additionally, heavy summer rains can seep into small cracks, weakening the sub-base and accelerating deterioration.
The heat also accelerates the evaporation of surface oils from asphalt, which causes brittleness and leads to surface cracking. For driveways and parking lots, this damage can compromise both function and appearance, reducing curb appeal and safety. Therefore, sealcoating is not just a cosmetic enhancement—it’s a critical protective layer that shields the surface from UV rays, moisture, and wear.
Types of Sealcoating Products and Their Suitability
When it comes to choosing a sealcoating product for your asphalt in Memphis, it’s important to understand the different types available. The three most common types of sealers are coal tar, asphalt emulsion, and acrylic-based sealers.
Coal tar sealers have long been favored for their durability and resistance to petroleum-based contaminants such as oil and gas. These sealers provide excellent protection against UV rays and are generally longer-lasting than other types. However, coal tar sealers contain higher levels of volatile organic compounds (VOCs) and have been restricted or banned in some regions due to environmental concerns. They also have a strong odor and require more drying time in humid climates, making them less ideal during particularly muggy Memphis days.
Asphalt emulsion sealers are a more environmentally friendly option made from a mix of asphalt, water, and emulsifying agents. These sealers are easier to apply and produce fewer fumes, making them suitable for residential areas. While they may not offer the same longevity as coal tar sealers, their performance has improved significantly, and they are a good choice for routine maintenance on driveways and light-traffic parking lots.
Acrylic-based sealers are premium products that offer exceptional resistance to UV radiation and color fading. These sealers are water-based and available in a range of colors, which adds aesthetic value. They’re especially effective in hot climates like Memphis, as they can reflect heat and reduce surface temperature. However, they tend to be more expensive and may require professional application.
Timing and Application Strategies for Hot Weather
Timing is everything when it comes to applying sealcoating during the summer. The ideal temperature for sealcoating is between 50°F and 85°F, but in Memphis, it’s common for temperatures to exceed 90°F. Applying sealcoat during the peak heat of the day can lead to premature drying and poor adhesion, reducing the effectiveness of the seal. Therefore, early morning or late afternoon applications are recommended to ensure proper curing.
Humidity also plays a role. While sealers need some moisture to cure properly, excessive humidity can prolong drying time, leaving the surface vulnerable to debris and foot traffic. To mitigate this, it’s essential to monitor the weather forecast and avoid application on days with a high chance of rain or extreme humidity.
Proper surface preparation is critical regardless of the weather. This includes cleaning the asphalt thoroughly to remove dirt, oil, and vegetation. Cracks should be filled, and damaged areas patched before the sealcoat is applied. A clean, smooth surface ensures optimal bonding and performance of the sealant. For larger parking lots or commercial properties, mechanical sprayers can provide even coverage and faster application, especially in expansive spaces.
Residential vs. Commercial Considerations
Choosing the right sealcoating also depends on whether you’re treating a residential driveway or a commercial parking lot. Homeowners in Memphis typically prioritize aesthetics, ease of application, and cost. For them, asphalt emulsion sealers often provide a balanced solution that offers adequate protection and a neat appearance without the environmental or odor concerns of coal tar.
On the other hand, commercial property managers overseeing parking lots or other high-traffic areas need sealcoating products with high durability and resistance to oil stains and abrasion. These properties see constant vehicle movement, heavier loads, and frequent exposure to fuel leaks. In such cases, coal tar or high-performance acrylic sealers are more suitable despite their higher cost and more complex application requirements.
Commercial paving projects also need to consider downtime. A busy parking lot can’t be shut down for days. Fast-drying sealers or phased applications—sealing one section at a time—can help businesses remain operational while still protecting their asphalt.
Memphis businesses may also face municipal regulations or environmental compliance concerns. It’s advisable to consult with professional paving contractors who are familiar with local codes and can recommend sealcoating solutions that meet both functional and legal requirements.
Long-Term Maintenance and Cost-Efficiency
Sealcoating is an investment in the longevity of your asphalt surface. In Memphis, where the summer elements are particularly harsh, regular maintenance can extend the life of a driveway or parking lot by several years. A well-sealed surface resists water penetration, oxidation, and softening, reducing the need for costly repairs like pothole patching or full resurfacing.
For residential asphalt, sealcoating every two to three years is typically sufficient. Commercial parking lots may require annual or biennial applications, depending on traffic levels. Although the upfront cost of sealcoating can vary—from $0.15 to $0.30 per square foot for basic products, and higher for premium sealers—it pales in comparison to the cost of repaving, which can exceed $3 to $5 per square foot.
To maximize cost-efficiency, property owners should schedule sealcoating as part of a broader paving maintenance plan. This includes regular inspections, crack sealing, and drainage management. In Memphis, sudden summer storms can cause localized flooding that undermines asphalt. Ensuring that your property has proper grading and water runoff systems will complement your sealcoating efforts and protect your investment.
Working with an experienced local paving contractor is one of the best ways to ensure success. These professionals understand the unique climate challenges of Memphis and can recommend tailored solutions that fit your budget, property type, and long-term goals.
Conclusion
Choosing the right sealcoating for the summer in Memphis is not a one-size-fits-all decision. It requires an understanding of the local climate, a careful evaluation of available products, and thoughtful planning for application and long-term care. Whether you’re protecting a residential driveway or managing a commercial parking lot, the right sealcoat can shield your asphalt from the punishing summer elements, enhance its appearance, and deliver years of reliable performance. Investing in the right product and working with knowledgeable paving professionals will ensure your asphalt surfaces remain safe, attractive, and durable throughout the hot Memphis season and beyond.
