If your asphalt driveway or parking lot in Lincoln, Nebraska looks dry, faded, or lightly cracked, sealcoating can help protect the surface and slow further deterioration. Proper application matters, though. Sealcoating works best when the pavement remains structurally sound and major damage has not developed.
What Is Asphalt Sealcoating?
Asphalt sealcoating is a protective surface treatment applied over existing asphalt. This thin coating helps shield pavement from weather, moisture, oxidation, and everyday traffic.
Think of sealcoating as preventative maintenance rather than a repair.
A quality sealcoat can:
- Protect asphalt from moisture.
- Reduce surface oxidation.
- Slow raveling, which is the loss of small aggregate from pavement.
- Cover minor surface imperfections.
- Improve the pavement’s dark, finished appearance.
- Help preserve an otherwise sound asphalt surface.
The Asphalt Institute describes seal coats as thin surface treatments that improve pavement texture and protect asphalt surfaces.
However, sealcoating cannot rebuild failed asphalt. Large potholes, deep cracks, drainage problems, and structural failures usually require additional repairs.
Why Does Asphalt Sealcoating Matter in Lincoln, NE?
Lincoln’s changing weather makes pavement maintenance especially important. Asphalt faces moisture, temperature changes, snow, and summer heat throughout the year.
According to Lincoln’s 1991–2020 climate normals, the area receives an average of 29.34 inches of precipitation and 26 inches of snowfall each year. Seasonal temperatures also vary considerably.
Consequently, local asphalt experiences repeated seasonal stress.
Winter can bring:
- Freezing temperatures.
- Snow and ice.
- Moisture entering pavement cracks.
- Freeze-and-thaw cycles.
Summer brings different challenges:
- High pavement temperatures.
- Sun exposure.
- Oxidation.
- Drying and surface aging.
Moisture deserves particular attention because water can enter cracks and contribute to pavement deterioration.
Lincoln Transportation and Utilities uses crack sealing as preventative maintenance. The process helps shield pavement from moisture and debris while extending the life of street surfaces.
For property owners, one point stands out: keeping water away from vulnerable asphalt is a major part of pavement preservation.
When Should You Sealcoat Asphalt in Lincoln?
The ideal time to sealcoat is when the pavement remains structurally sound but shows early signs of surface aging.
Several warning signs can indicate that maintenance may be appropriate:
- The asphalt is turning gray.
Fading can indicate oxidation and surface aging. - Small surface cracks are appearing.
Minor cracking can often be addressed as part of a broader maintenance plan. - The surface looks dry or brittle.
Older asphalt can lose some of its flexibility over time. - Small amounts of aggregate are becoming loose.
This condition is known as raveling. - The pavement still feels solid under traffic.
Sealcoating works best before deeper structural problems develop.
The Asphalt Institute recommends sealing driveways and parking lots when aging causes asphalt to become dry and brittle. Small surface cracks, surface voids, or raveling can also indicate that sealing may be appropriate.
Should New Asphalt Be Sealcoated Immediately?
No. Newly installed asphalt generally needs time to cure before sealing.
For a properly designed and constructed low-traffic pavement, such as a driveway or parking lot, the Asphalt Institute says sealing generally should not be necessary for approximately 2 to 5 years. Climate and original construction quality can affect that timeline.
Instead of automatically sealing new pavement, a contractor should inspect the surface and determine whether treatment is appropriate.
What Does Asphalt Sealcoating Protect Against?
Sealcoating primarily protects the asphalt surface from the elements and normal surface wear.
Moisture
Water can enter cracks and pavement voids. Preventing moisture from penetrating vulnerable areas can help reduce additional deterioration.
Oxidation
Sunlight and exposure to air cause asphalt binders to age. Over time, pavement can become harder and more brittle.
Surface Wear
Traffic gradually wears pavement. A protective surface treatment can help slow certain forms of surface deterioration.
Weather Exposure
Lincoln pavement must handle both winter and summer conditions. Regular maintenance helps keep minor surface problems from becoming larger issues.
Appearance
Fresh sealcoating gives older asphalt a darker, cleaner appearance. That improvement can make a residential driveway, commercial parking lot, or business property look better maintained.
How Does Asphalt Sealcoating Work?
A professional sealcoating project involves much more than spraying material over a driveway.
Most projects follow several important steps.
1. Inspect the Asphalt
Before work begins, the contractor evaluates the pavement.
During this inspection, they should identify:
- Cracks.
- Potholes.
- Drainage problems.
- Weak areas.
- Oil contamination.
- Surface deterioration.
- Areas that require patching.
This evaluation determines whether sealcoating is appropriate.
2. Clean the Surface
Dirt, leaves, loose aggregate, and other debris must be removed.
Proper cleaning gives the coating a better surface to bond with.
3. Repair Cracks and Damage
Cracks should be addressed before the sealcoat is applied.
Lincoln’s own crack-sealing process includes cleaning debris and moisture from cracks before filling them with hot-pour rubber sealant.
Larger pavement failures may require patching or other repairs instead.
4. Apply the Sealcoat
The sealcoating material is applied in a consistent layer across the prepared pavement.
Application rates should match the pavement’s condition and surface texture.
According to the Asphalt Institute, excessive application can cause problems such as material pickup on tires or shoes.
5. Allow the Surface to Cure
Sufficient curing time is necessary before normal traffic returns.
After the application, a contractor should provide clear instructions about when vehicles and pedestrians can use the surface again.
Can Sealcoating Fix Cracks and Potholes?
No. Sealcoating is not a substitute for pavement repair.
Minor surface cracks may be addressed as part of a maintenance project. Significant cracks and potholes, however, require proper repair first.
Sealcoating Is Appropriate For:
- Faded asphalt.
- Dry-looking pavement.
- Minor surface aging.
- Light surface cracking.
- Early signs of raveling.
- Structurally sound driveways.
- Structurally sound parking lots.
Sealcoating Is Not a Fix For:
- Large potholes.
- Major alligator cracking.
- Failing pavement bases.
- Severe rutting.
- Major drainage problems.
- Severely deteriorated asphalt.
Structural failure requires more than a protective coating. Applying sealcoating over failing pavement will not solve the underlying problem.
The Asphalt Institute specifically cautions that surface treatments should be used on structurally sound pavement. Defects can quickly reflect through a new surface when the underlying pavement is failing.
How Often Should Asphalt Be Sealcoated?
There is no universal schedule for every property. Pavement condition, traffic, weather, installation quality, and maintenance history all affect performance.
Rather than sealing according to a fixed calendar, inspect the pavement regularly.
A practical maintenance cycle looks like this:
- Inspect the pavement.
- Identify new cracks or surface deterioration.
- Repair cracks and pavement damage.
- Determine whether the asphalt remains structurally sound.
- Apply sealcoating when conditions are appropriate.
- Continue routine inspections.
This approach helps prevent unnecessary applications while encouraging early attention to developing problems.
What Is the Best Time of Year for Sealcoating in Lincoln?
The best application window depends on suitable weather and pavement conditions. Choosing a particular month does not guarantee proper curing conditions.
Sealcoating generally needs warm, dry conditions so the material can cure properly.
Lincoln’s climate provides a good reason to plan pavement maintenance around warmer months. The city’s average normal high reaches about 89.4°F in July, while January’s normal high is about 35.6°F.
As a result, spring, summer, and early fall can provide more practical application opportunities than cold-weather periods.
Contractors should still consider:
- Pavement temperature.
- Air temperature.
- Rain forecasts.
- Overnight temperatures.
- Humidity.
- Expected curing conditions.
A professional contractor should evaluate the actual weather forecast before beginning the project.
Is Sealcoating Worth It for a Lincoln Driveway?
Yes. Sealcoating can be worthwhile when a driveway remains structurally sound and begins showing normal surface aging.
Residential driveways benefit from preventative maintenance because small surface problems are generally easier to address than major pavement failures.
Beyond protection, sealcoating can improve curb appeal by restoring a darker, more uniform appearance.
Homeowners should not use sealcoating to hide significant pavement damage, however. Extensive cracking or failing areas require a contractor to explain repair options first.
Is Sealcoating Worth It for a Commercial Parking Lot?
Sealcoating can be especially useful for commercial parking lots. These surfaces receive regular vehicle traffic and remain highly visible to customers.
A well-maintained parking lot can:
- Improve the property’s appearance.
- Protect the pavement surface.
- Slow surface deterioration.
- Support a regular maintenance program.
- Help address minor pavement problems before they become more expensive.
Lincoln has also used asphalt sealing as part of pavement preservation. During a 2021 city project, sealant was applied to entire roadway sections to help slow aging, preserve flexibility, and extend the driving surface.
That project provides a local example of sealcoating’s role in preventative pavement maintenance.
What Is the Difference Between Sealcoating and Crack Sealing?
Sealcoating protects the broader pavement surface, while crack sealing specifically treats individual cracks.
Sealcoating
A sealcoat creates a protective layer across the asphalt surface.
Its primary purpose is surface preservation.
Crack Sealing
Crack sealing fills individual cracks with a flexible sealant. This treatment helps keep moisture and debris out.
Together, these treatments can form part of an effective pavement maintenance program.
For example, a parking lot may need cracks cleaned and sealed before the broader surface receives a sealcoat.
Sealcoating vs. Asphalt Resurfacing: Which Do You Need?
The appropriate treatment depends on the condition of the existing pavement.
| Pavement Condition | Potential Treatment |
|---|---|
| New, healthy asphalt | Routine inspection |
| Faded or dry surface | Sealcoating |
| Minor cracks | Crack sealing + sealcoating |
| Small potholes | Patching + sealcoating |
| Moderate deterioration | Evaluate for resurfacing |
| Severe structural failure | Reconstruction or major rehabilitation |
Sealcoating is a preservation treatment, not a structural rehabilitation method.
That distinction matters when comparing contractor recommendations. A reputable contractor should explain why a particular treatment fits the pavement’s condition.
How Much Does Asphalt Sealcoating Cost in Lincoln?
The cost of asphalt sealcoating in Lincoln depends on pavement size, condition, preparation requirements, and project type.
Several factors can affect the final price:
- Total square footage.
- Residential or commercial use.
- Amount of crack sealing required.
- Patching requirements.
- Surface condition.
- Accessibility.
- Number of coats.
- Material and application method.
Because every property is different, a contractor should inspect the pavement before providing a final price.
Be cautious with quotes that focus only on a low price per square foot. Proper preparation can have a major effect on the finished result.
How Do You Choose an Asphalt Sealcoating Contractor in Lincoln?
Look for a contractor that evaluates the pavement first, explains the preparation process, and provides a clear scope of work.
Before hiring a company, ask these questions:
- Will you inspect the pavement before quoting the job?
- What repairs need to be completed first?
- How will you clean and prepare the asphalt?
- Will cracks be sealed before the coating is applied?
- What sealcoating material will you use?
- How many coats are recommended?
- How long should the pavement remain closed?
- What weather conditions are required?
- What areas are included in the quote?
- What maintenance should I plan for afterward?
A quality contractor should answer these questions clearly without making unrealistic promises.
What Should You Do Before Your Lincoln Sealcoating Project?
A little preparation can make the project easier and help the contractor complete the work efficiently.
Before the Contractor Arrives
- Remove vehicles from the pavement.
- Move outdoor furniture and other items.
- Keep sprinklers away from the work area.
- Identify drainage concerns.
- Point out known cracks or damaged areas.
- Keep children and pets away from the work zone.
- Follow the contractor’s traffic restrictions.
Most importantly, avoid driving on newly treated pavement until the contractor confirms that it has cured sufficiently.
What Are the Benefits of Regular Asphalt Maintenance?
Regular maintenance helps preserve usable pavement before major rehabilitation becomes necessary.
The Asphalt Institute describes pavement preservation as a long-term strategy designed to improve pavement performance and delay more extensive rehabilitation.
A maintenance program can include:
- Crack sealing.
- Sealcoating.
- Patching.
- Surface treatments.
- Drainage maintenance.
- Periodic pavement inspections.
The goal is simple: maintain good pavement before it becomes bad pavement.
Frequently Asked Questions About Asphalt Sealcoating in Lincoln
How long does asphalt sealcoating last?
Service life varies based on pavement condition, traffic, weather, materials, and application quality. A contractor should evaluate the surface and recommend a maintenance interval based on its actual condition.
Can you sealcoat asphalt with cracks?
Yes, if the cracks are minor and properly treated first. Larger or structural cracks require additional repairs.
Can sealcoating stop potholes?
No. Sealcoating can help protect sound pavement, but it does not repair potholes. Potholes should be properly patched before sealcoating.
Can you sealcoat a new driveway?
Usually not immediately. The Asphalt Institute says new low-traffic pavement generally should not require sealing for approximately 2 to 5 years, depending on climate and construction quality.
Does sealcoating prevent asphalt from aging?
Sealcoating can slow certain forms of surface aging, but it cannot stop asphalt deterioration completely. Regular inspections and timely repairs remain important.
Is sealcoating good for commercial parking lots?
Yes. Sealcoating can help preserve structurally sound commercial pavement while improving its appearance.
Does Lincoln weather affect asphalt?
Yes. Lincoln experiences significant seasonal temperature changes, precipitation, and snowfall. Its 1991–2020 climate normals include 29.34 inches of annual precipitation and 26 inches of annual snowfall.
What happens if I wait too long to sealcoat?
Waiting until pavement develops extensive cracking, potholes, or structural failure can eliminate sealcoating as the appropriate solution. More extensive repairs may become necessary at that point.
The Bottom Line on Asphalt Sealcoating in Lincoln
Asphalt sealcoating is most effective as preventative maintenance for sound pavement that is beginning to show surface aging. It can help protect asphalt from moisture and weather exposure while improving its appearance.
For Lincoln property owners, regular pavement inspections provide the best starting point. Addressing minor problems early can help prevent larger and more expensive repairs.
