How Sealcoating Protects Your Asphalt Investment

Asphalt surfaces look great when freshly laid, but they don’t stay that way forever. Rain, sun, oil, and everyday traffic slowly break them down. Cracks appear and potholes form, and before you know it, your driveway or parking lot looks damaged and worn out.

That’s where sealcoating comes in. Sealcoating is like a protective shield for your asphalt. It helps maintain your investment, saves you from expensive repairs, and extends the life of your pavement. 

Let’s understand how sealcoating works, why it’s important, and how it helps protect the value of your property.

What is Sealcoating?

Sealcoating is a process that involves applying a protective layer of liquid asphalt over the surface of your asphalt pavement. 

This liquid coating helps in creating a barrier that shields your pavement from harmful elements such as water, sunlight, oils, and chemicals. 

It’s like applying sunscreen to protect your skin from the sun, only in this case, it protects your pavement from the damaging effects of UV rays, water infiltration, and other environmental factors.

Sealcoating is an essential maintenance service for asphalt surfaces, especially for driveways, parking lots, roads, and any other surface exposed to heavy use. 

It prevents minor damage from turning into larger, costlier repairs and extends the lifespan of your asphalt.

Why is Sealcoating Important for Asphalt?

Asphalt is a durable material, but it is not invincible. Over time, exposure to weather conditions, vehicle traffic, and chemicals can cause the surface to deteriorate. 

Without a protective sealcoat, your asphalt is prone to developing cracks, potholes, and fading. 

Sealcoating helps preserve the asphalt’s structural integrity by acting as a protective layer, reducing wear and tear, and enhancing its appearance.

Key Benefits of Sealcoating

Sealcoating offers several important benefits that help maintain and protect your asphalt over time.

Protects Asphalt from Sun, Water, and Chemicals

One of the primary reasons for sealcoating is to protect the asphalt from the harmful effects of the sun and water. 

UV rays can cause the asphalt to dry out, which leads to cracking and fading. Water infiltration is another major concern, as it can erode the surface over time, especially in colder climates where water can freeze and expand in cracks. 

Sealcoating also prevents gasoline, oil, and other chemicals from penetrating the asphalt, which can cause long-term damage.

Prevents Early Cracks and Potholes

Potholes and cracks often begin as small imperfections that, over time, grow larger if not addressed. 

Sealcoating helps to fill in minor cracks and voids on the surface, reducing the risk of water infiltration and the formation of potholes. 

By applying a sealcoat, you are preventing the development of these larger issues that could require expensive repairs.

Makes Your Asphalt Look New Again

A freshly applied sealcoat gives your asphalt a deep, black, and shiny appearance. Not only does this enhance the aesthetic appeal of your property, but it also increases curb appeal. 

Whether it’s your home driveway or a commercial parking lot, a well-maintained asphalt surface looks much more attractive and well-kept. 

The sealcoat restores the surface to its original look, making it appear new again.

Extends the Life of Your Asphalt Surface

When properly maintained with regular sealcoating, asphalt can last for decades. Sealcoating provides a protective layer that can effectively double the lifespan of your pavement. 

Rather than dealing with costly resurfacing or total asphalt replacement, sealcoating provides a long-term solution that can help you get more out of your initial investment.

Saves You Money on Future Repairs

Regularly sealcoating your asphalt can save you significant amounts of money in the long run. 

By preventing cracks and potholes, sealcoating reduces the likelihood of major damage that requires expensive repairs. 

It’s a cost-effective way to maintain the integrity of your pavement and avoid unnecessary repair bills.

Is Sealcoating Worth the Cost?

Absolutely! Compared to the price of full asphalt replacement, sealcoating is affordable preventive maintenance.

Let’s compare:

Service TypeAverage Cost per Square Foot
Sealcoating$0.15 – $0.30
Full Replacement$3.00 – $6.00

A small investment now saves thousands later.

How the Sealcoating Process Works

The sealcoating process involves a few simple steps that help protect and extend the life of your asphalt surface.

Step 1: Clean the Surface

Before applying the sealcoat, the asphalt surface must be thoroughly cleaned. This involves removing debris such as leaves, dirt, and gravel, as well as oil stains or other contaminants. 

Cleaning ensures that the sealcoat properly adheres to the asphalt, providing the maximum level of protection.

Step 2: Fill Small Cracks

Next, small cracks in the asphalt are filled using a specialized crack filler. These cracks can be minor, but if left untreated, they can lead to further deterioration over time. Filling them before applying the sealcoat ensures a smooth and even surface.

Step 3: Apply the Sealcoat Evenly

Once the surface is prepared, the sealcoat is applied evenly over the entire asphalt area. This is typically done using a sprayer or a brush, depending on the size of the area. 

The goal is to cover the asphalt with a thin, uniform layer of sealant that bonds well with the surface.

Step 4: Let it Dry Properly

After the sealcoat is applied, it needs time to dry and cure. Typically, this process takes about 24-48 hours, depending on the weather conditions. 

During this time, it is important to keep the surface free from traffic to ensure the sealant sets correctly.

Best Time of Year to Sealcoat

The ideal time for sealcoating is during dry, warm weather. The best months for sealcoating are typically late spring to early fall when temperatures range between 55°F and 90°F. 

Sealcoating should not be performed during rainy or extremely cold conditions, as this can affect the quality of the application.

How Often Should You Sealcoat Your Asphalt?

Sealcoating isn’t a one-time job, it’s part of a regular maintenance plan to keep your asphalt strong and long-lasting.

Then follow with:

Suggested Maintenance Schedule

Experts recommend sealcoating your asphalt surface every 2-3 years, depending on the amount of traffic the surface receives and the climate conditions in your area. High-traffic areas or areas exposed to harsh weather may need more frequent sealcoating.

Signs Your Asphalt Needs Sealcoating Again

You should consider sealcoating your asphalt again if you notice the following signs:

  • The asphalt color is fading.
  • Hairline cracks are beginning to appear.
  • The surface feels rough or uneven.
  • Water starts pooling on the surface instead of draining away.
  • Common Sealcoating Mistakes to Avoid

Not Cleaning the Surface First

If the surface isn’t properly cleaned before sealcoating, dirt and debris can interfere with the adhesion of the sealant. This can lead to an uneven finish and premature wear. Always ensure that the surface is clean before starting the sealcoating process.

Applying in Bad Weather

Sealcoating should only be done in dry, warm weather. Applying a sealcoat during cold or rainy conditions can result in poor adhesion and an ineffective finish. Always check the weather forecast before scheduling the service.

Using Low-Quality Sealants

Low-quality or cheap sealants may not provide the protection your asphalt needs. These sealants can wear off quickly, leading to premature damage. It’s important to invest in high-quality sealants to ensure long-lasting results.

Skipping Regular Maintenance

Sealcoating is not a one-time fix. To maximize the lifespan of your asphalt, it is essential to incorporate regular sealcoating as part of an ongoing maintenance plan. Skipping this service can lead to more significant issues and expensive repairs.
