The Ultimate Guide to Asphalt Sealcoating: Answers to Your Most Asked Questions


When it comes to preserving and protecting your asphalt surfaces, sealcoating can be your pavement's best friend. In regions like Kerrville, Texas where the Texas sun and fluctuating temperatures can take a toll on roads and driveways, the benefits of sealcoating are more than just cosmetic. This thick, black, water-resistant material provides a protective layer, extending the life of your pavement and giving a smooth finish to boot. But before you jump into sealcoating, you probably have a few questions. That's why we've gathered the most frequently asked questions about this essential pavement maintenance procedure.


Understanding Sealcoating Basics

What is Sealcoating and Why Is It Important?

Sealcoating is the application of a layer of protective material over an existing asphalt pavement surface. This procedure is an essential part of pavement maintenance for several reasons. First and foremost, it helps to waterproof the surface, which is crucial in preventing water penetration that can lead to cracks and potholes. Additionally, sealcoating enhances the appearance of the asphalt, giving it that fresh, jet-black look that's so appealing.

When Should I Consider Sealcoating My Pavement?

Regular maintenance is key to the longevity of your pavement, and sealcoating should be part of that routine. Most experts recommend sealcoating your asphalt surface every two to three years, but this can vary depending on usage and environmental factors. For instance, a high-traffic commercial parking lot may need to be sealcoated more frequently than a residential driveway.

How Does Sealcoating Protect My Pavement?

Sealcoating acts as a barrier against the elements. Ultraviolet rays from the sun can damage the asphalt binder, leading to a brittle, gray surface that's prone to cracking. Sealcoating helps to shield the asphalt from these harmful rays. Water, another common adversary, can seep into the pavement, freeze, and expand, causing cracks and potholes. Sealcoating prevents water infiltration, thus protecting the integrity of the pavement.

Preparing for Sealcoating

What Steps Should I Take Before Sealcoating My Driveway?

Before sealcoating, it's important to prepare the surface adequately. This typically involves cleaning the pavement to remove dirt and debris. Additionally, any existing cracks should be filled and the pavement repaired as needed. Proper preparation ensures that the sealcoating material adheres correctly and provides the best protection.

Can I Sealcoat My Driveway Myself or Should I Hire a Professional?

While there are DIY sealcoating kits available, it's generally best to leave this job to the professionals. A professional sealcoating service will have the necessary equipment and expertise to apply the sealcoat evenly and effectively. They will also be able to address any issues with your pavement, such as cracks or oil stains, before sealcoating.

How Long Does the Sealcoating Process Take?

The time it takes to sealcoat a pavement can vary depending on the size of the area, the condition of the pavement, and the weather conditions. Generally, you can expect the process to take a few hours to a full day.

Sealcoating Material and Application

What Type of Sealcoating Material Should I Use?

There are two main types of sealcoating materials: coal tar emulsion and asphalt emulsion. Coal tar emulsion is more durable and offers better resistance to oil and gasoline spills, making it a popular choice for commercial applications. Asphalt emulsion sealers are more environmentally friendly and may be preferred for residential use.

How Is Sealcoating Applied?

Sealcoating is typically applied using a spray system, a squeegee, or a brush—depending on the area being sealed and the type of sealcoating material used. The application process should be done in a consistent manner to ensure an even coat.

What Should I Expect After Sealcoating My Driveway?

After sealcoating, it's important to allow the pavement to cure. This can take anywhere from 8 to 36 hours, depending on the type of sealcoating material and the weather. During this time, the surface may be tacky and should not be driven or walked on.

Sealcoating and Environmental Considerations

Is Sealcoating Environmentally Safe?

Coal tar sealers have been a topic of environmental concern due to their high PAH (Polycyclic Aromatic Hydrocarbon) content, and some municipalities have banned their use. Asphalt emulsion sealers are generally considered to be more environmentally friendly.

What Is the Environmental Impact of Sealcoating?

The potential environmental impact of sealcoating varies depending on the material used and how it is applied. There are concerns about contaminated runoff and the impact on local ecosystems. To minimize the environmental impact, it's important to choose your sealcoating contractor carefully and to properly dispose of any leftover sealcoating material.

Cost and ROI of Sealcoating

How Much Does Sealcoating Cost?

The cost of sealcoating can vary widely depending on factors such as the size of the area, the condition of the pavement, and the type of sealcoating material used. It's best to get a quote from a professional sealcoating service based on your specific needs.

What Is the Return on Investment of Sealcoating?

Sealcoating is a relatively inexpensive way to protect and extend the life of your pavement. It can help you avoid costly repairs down the line by preventing damage before it occurs. For commercial properties, sealcoating can also enhance the curb appeal and safety of the parking lot, potentially attracting more customers.

Common Sealcoating Misconceptions

Will Sealcoating Fill In Cracks and Potholes?

Sealcoating is not a substitution for repairing pavement. While sealcoating can help to prevent cracks and potholes by providing a layer of protection, it will not fill in existing cracks or potholes.

Is Sealcoating a One-Time Fix for My Pavement?

Sealcoating is not a permanent solution. It is a part of a regular maintenance routine that also includes crack filling and other repairs. Regular upkeep will ensure that your pavement lasts as long as possible.

Can Sealcoating Be Applied to Newly Laid Asphalt?

Newly laid asphalt should be allowed to cure and weather for a certain period of time before sealcoating. Your asphalt contractor can advise you on the appropriate timeline.

Sealcoating Choose Your Own Adventure

Going the DIY Route with Sealcoating

If you're set on the DIY path, there are some key points to keep in mind. You'll need to thoroughly clean your driveway, use the appropriate material, and follow the manufacturer's instructions carefully. Remember, a haphazardly sealcoated driveway won't provide the same level of protection or aesthetics as a professionally-applied coat.

Finding the Right Sealcoating Contractor

When choosing a professional contractor, don't just go with the lowest bid. Look for a company with a good reputation and experience in the sealcoating business. Ask for references, check reviews, and ensure they are properly licensed and insured.

Investing in Ongoing Pavement Maintenance

Sealcoating is just one piece of the pavement maintenance puzzle. Regular inspections, crack filling, and other repairs are essential to keeping your pavement in top condition. Develop a maintenance plan and stick to it to maximize the life of your asphalt surfaces.
