Maintaining your asphalt driveway or parking lot can significantly extend its lifespan and improve its curb appeal. A key element in this maintenance is the application of a high-quality blacktop sealer. With a myriad of products available on the market, choosing the best blacktop sealer can be a daunting task. Factors such as durability, ease of application, resistance to weather elements, and cost-effectiveness all play crucial roles in determining the right product for your needs. This article delves into the different types of blacktop sealers, their pros and cons, and key considerations to help you make an informed decision and protect your investment. We'll explore everything from coal tar sealers to acrylic options, examining their performance and suitability for various climates and traffic levels. Ultimately, understanding the nuances of blacktop sealers will empower you to choose the product that offers the most value and longevity for your asphalt surface.
Understanding Different Types of Blacktop Sealers
Choosing the right blacktop sealer begins with understanding the different types available. The two most common categories are coal tar-based sealers and asphalt-based sealers. Each has its own unique properties, advantages, and disadvantages. Coal tar sealers are known for their superior resistance to oil, gasoline, and other chemicals, making them a popular choice for commercial properties and areas with heavy traffic. However, they contain polycyclic aromatic hydrocarbons (PAHs), which have raised environmental and health concerns. Asphalt-based sealers, on the other hand, are considered more environmentally friendly and often have a lower VOC (volatile organic compound) content. While they may not be as resistant to chemicals as coal tar sealers, they still offer excellent protection against water penetration, UV damage, and general wear and tear. Ultimately, the choice between the two depends on your specific needs and priorities, balancing performance with environmental considerations.
Key Factors to Consider When Choosing a Sealer
Selecting the best blacktop sealer involves careful consideration of several key factors. Firstly, assess the condition of your asphalt surface. Are there cracks, potholes, or significant damage? If so, these issues need to be addressed before applying any sealer. Secondly, consider the climate in your area. Regions with harsh winters and heavy snowfall require sealers that offer superior freeze-thaw resistance. Thirdly, evaluate the amount of traffic your asphalt surface experiences. High-traffic areas, such as commercial parking lots, demand sealers with exceptional durability and resistance to wear and tear. Furthermore, take into account your budget. While it's tempting to opt for the cheapest option, investing in a higher-quality sealer can save you money in the long run by providing better protection and lasting longer. Finally, research different brands and read reviews to get a sense of their performance and customer satisfaction.
Preparation is Key: Before Applying the Sealer
Proper preparation is paramount for ensuring the successful application and longevity of your blacktop sealer. Failing to adequately prepare the surface can lead to poor adhesion, premature cracking, and ultimately, a wasted effort. The first step is to thoroughly clean the asphalt surface, removing all dirt, debris, oil stains, and vegetation. Use a stiff brush or broom and a pressure washer if necessary. Address any cracks or potholes with a suitable asphalt crack filler or patching compound, allowing it to cure completely before proceeding. Next, apply a primer if recommended by the sealer manufacturer, especially on older or severely weathered asphalt. This will improve adhesion and ensure a uniform finish. Finally, check the weather forecast to ensure that there is no rain expected for at least 24-48 hours after application, as moisture can interfere with the curing process.
Application Techniques for Optimal Results
The application technique significantly impacts the final outcome and performance of your blacktop sealer. Always follow the manufacturer's instructions carefully, as application methods may vary depending on the specific product. Generally, sealers can be applied using a squeegee, brush, or spray equipment. Squeegees are ideal for achieving a smooth, even coat, while brushes are better suited for smaller areas or intricate details. Spray equipment can cover large areas quickly and efficiently, but requires more skill and precision to avoid overspray. Apply the sealer in thin, even layers, overlapping each pass slightly to ensure complete coverage. Avoid applying too much sealer in one coat, as this can lead to cracking and peeling. Allow each coat to dry completely before applying the next, following the manufacturer's recommended drying time. Ensure proper ventilation during application, especially when using solvent-based sealers.

Choosing the right brand and product can be overwhelming, given the variety available. Some of the best reviewed and most trusted brands in the market include GemSeal, Neyra, SealMaster, and Black Knight. GemSeal offers a range of coal tar and asphalt-based sealers known for their durability and resistance to chemicals.

When selecting a specific product, consider factors such as coverage area, drying time, VOC content, and customer reviews. Reading online reviews and comparing product specifications can help you make an informed decision and choose the product that best suits your needs and budget.
Maintenance and Longevity: Extending the Life of Your Sealed Blacktop
Applying blacktop sealer is an investment, and proper maintenance is essential to maximize its lifespan and protect your asphalt surface. Regular sweeping and cleaning are crucial to remove dirt, debris, and oil stains that can degrade the sealer over time. Promptly repair any cracks or potholes that develop, as these can allow water to penetrate and damage the underlying asphalt. Avoid using harsh chemicals or abrasive cleaners that can strip the sealer. Consider applying a fresh coat of sealer every 2-3 years, depending on the level of traffic and weather conditions. This will help maintain the protective barrier and prevent premature deterioration of the asphalt. By following these maintenance tips, you can significantly extend the life of your sealed blacktop and keep it looking its best for years to come.
