Selecting the appropriate asphalt sealer is a long-term investment in your property, and we’re here to help you navigate the options with confidence.
Understanding Asphalt Sealer Types
There are primarily two types of asphalt sealers: coal tar-based and asphalt-based. Each offers distinct advantages and disadvantages, making the choice dependent on your specific needs and environmental considerations. Coal tar sealers are known for their superior resistance to oil and gasoline spills, making them a popular choice for high-traffic areas or locations prone to vehicle leaks. However, they contain polycyclic aromatic hydrocarbons (PAHs), which have raised environmental and health concerns in recent years. Asphalt-based sealers, on the other hand, are considered more environmentally friendly and offer good overall protection against the elements. They may not be as resistant to chemical spills as coal tar sealers, but they are a viable option for residential driveways and areas with lower traffic volume. Understanding the differences between these two types is the first step in selecting the best sealer for your specific application.
Factors to Consider Before Choosing
Before you rush into purchasing an asphalt sealer, take some time to assess the specific conditions of your asphalt surface and the surrounding environment. Factors such as the amount of traffic the area receives, the climate in your region, and the existing condition of the asphalt will all play a role in determining the best sealer for your needs. For example, if you live in an area with harsh winters and frequent freeze-thaw cycles, you'll want a sealer that offers excellent flexibility and resistance to cracking. Similarly, if your driveway is heavily used by multiple vehicles, you'll need a sealer that can withstand the wear and tear of constant traffic. Consider also any specific problems with your asphalt, such as existing cracks or oil stains, and choose a sealer that is designed to address those issues. Thoroughly evaluating these factors will help you narrow down your options and select a product that will provide long-lasting protection and enhance the appearance of your asphalt surface.
Preparing Your Asphalt Surface
Proper preparation is key to ensuring that your asphalt sealer adheres correctly and provides optimal protection. Before applying any sealer, you'll need to thoroughly clean the asphalt surface to remove any dirt, debris, oil stains, or loose gravel. Start by sweeping the entire area with a stiff broom to remove any large particles. Then, use a pressure washer to blast away any remaining dirt and grime. For oil stains, you may need to use a specialized degreaser to break down the oil before rinsing it away. Once the surface is clean, inspect it for any cracks or holes. Fill these with an asphalt crack filler, allowing it to dry completely before proceeding. Finally, allow the asphalt surface to dry completely before applying the sealer. This may take several hours or even a full day, depending on the weather conditions. Taking the time to properly prepare your asphalt surface will ensure that the sealer adheres correctly and provides long-lasting protection.
Application Techniques for Asphalt Sealer
Applying asphalt sealer correctly is crucial for achieving the desired results. There are several methods you can use, including using a squeegee, a brush, or a spray applicator. Each method has its own advantages and disadvantages, depending on the size and condition of your asphalt surface. For smaller driveways or areas with intricate designs, a squeegee or brush may be the best option, as they allow for more precise application. For larger parking lots or driveways, a spray applicator can be a more efficient choice, as it can cover a wider area in less time. Regardless of the method you choose, it's important to apply the sealer in thin, even coats, avoiding any pooling or puddling. Allow each coat to dry completely before applying the next one, following the manufacturer's instructions for drying time. Overlapping each pass slightly will help ensure complete coverage and prevent any gaps in the sealant. Always wear appropriate safety gear, including gloves and eye protection, when applying asphalt sealer.
Top Asphalt Sealer Recommendations
Choosing the best asphalt sealer depends greatly on individual needs. However, some brands and products consistently receive high ratings for their performance and durability.
Coal Tar-Based Sealers
While environmental concerns have led to a decrease in their popularity, coal tar-based sealers remain a viable option for certain applications due to their superior resistance to oil and gasoline. One popular choice is GemSeal, known for its long-lasting protection and ability to withstand heavy traffic. However, it's crucial to check local regulations before using coal tar-based sealers, as they are banned in some areas. When applying coal tar sealers, ensure proper ventilation and wear appropriate protective gear to minimize exposure to PAHs. Consider the long-term environmental impact before choosing this type of sealer. Despite the potential drawbacks, the durability and resistance offered by coal tar-based sealers can make them the best choice for specific commercial or industrial applications where chemical spills are a common occurrence. Always weigh the benefits against the environmental considerations and adhere to all applicable regulations.
Asphalt-Based Sealers
For a more environmentally friendly option, asphalt-based sealers offer excellent protection and durability for residential driveways and parking lots. SealMaster is a widely respected brand known for its high-quality asphalt-based sealers that provide excellent resistance to weathering and cracking. These sealers are easy to apply and offer a long-lasting finish, making them a popular choice among homeowners. Another great option is Latex-Ite, which is formulated with polymers for added flexibility and durability. This sealer is particularly effective in areas with frequent freeze-thaw cycles. Asphalt-based sealers are also generally easier to work with than coal tar-based sealers, requiring less specialized equipment and posing fewer health risks. They are a great all-around choice for anyone looking to protect their asphalt surfaces without compromising environmental responsibility. Remember to follow the manufacturer's instructions for application and drying times to ensure optimal results. Regular maintenance and reapplication every few years will help prolong the life of your asphalt surfaces and keep them looking their best.
Extending the Life of Your Sealed Asphalt
Applying asphalt sealer is just the first step in maintaining your asphalt surfaces. To maximize the lifespan of your sealed asphalt, it's important to implement a few simple maintenance practices. Regularly sweep the surface to remove any dirt or debris that could damage the sealant. Promptly clean up any oil or gasoline spills to prevent them from penetrating the sealant. Avoid using harsh chemicals or abrasive cleaners, as these can damage the surface. Consider applying a second coat of sealer after the first coat has fully cured to provide an extra layer of protection. Schedule regular inspections to identify and address any cracks or damage early on. By following these simple tips, you can extend the life of your sealed asphalt and keep it looking its best for years to come. Regular maintenance is a small investment that can save you significant costs in the long run by preventing major repairs or replacements.
