Faded, dry, or lightly worn asphalt does not always need to be replaced. Professional asphalt sealcoating adds a protective layer over the pavement, helping reduce damage caused by sunlight, moisture, vehicle traffic, oil, and Michigan’s changing weather.
Anthony’s Asphalt provides residential and commercial asphalt sealcoating for driveways, parking lots, private roads, HOA communities, schools, industrial properties, and other paved surfaces throughout Ann Arbor, Dexter, Chelsea, Saline, Brighton, Howell, and Southeast Michigan.
Our team evaluates the pavement before recommending service. If sealcoating is appropriate, we prepare the surface carefully, address eligible cracks, and apply a uniform protective coating designed to support longer pavement life.
What Is Asphalt Sealcoating?
Asphalt sealcoating is a preventive pavement maintenance service. A protective coating is applied over an existing asphalt surface to slow oxidation, limit water penetration, and protect the pavement from everyday exposure.
As asphalt ages, its binding oils gradually dry out. The surface may turn gray, become brittle, and develop small cracks. UV exposure, rain, snow, deicing materials, vehicle traffic, and fluid spills can accelerate this deterioration.
Sealcoating creates a protective barrier over the surface. It can also restore the dark, uniform appearance associated with properly maintained asphalt.
However, sealcoating is not a structural repair. It will not rebuild a failed base, remove potholes, or correct severe drainage problems. Damaged areas may require asphalt repair, patching, or resurfacing before the property is ready for sealcoat.
Benefits of Asphalt Sealcoating for Michigan Properties
A properly prepared and professionally sealed surface can provide several practical benefits.
- Slows oxidation: Sealcoat limits direct UV exposure that causes asphalt binders to dry and become brittle.
- Reduces water intrusion: A maintained surface is less vulnerable to water entering small voids and surface openings.
- Protects against normal wear: The coating provides an additional barrier against traffic, weather, and minor surface abrasion.
- Improves resistance to spills: Sealcoating can reduce the pavement’s direct exposure to oil, fuel, and other vehicle fluids.
- Restores a consistent appearance: It renews faded gray pavement with a clean, dark finish.
- Supports longer pavement life: Preventive maintenance can delay more extensive deterioration and premature replacement.
- Improves property presentation: A maintained driveway or parking lot creates a better first impression for residents, visitors, customers, and tenants.
- Makes pavement markings more visible: On commercial parking lots, a dark sealed surface creates better contrast for freshly applied striping.
The best results come from treating sealcoating as one part of a complete pavement maintenance plan. Cracks, potholes, drainage issues, and worn markings should each be addressed with the correct service.
Where Asphalt Sealcoating Works Best
Sealcoating is most effective on asphalt that remains structurally stable but shows early signs of surface aging.
Good candidates often include:
- Asphalt driveways with a faded or dry surface
- Commercial parking lots with light surface wear
- HOA and condominium roads
- Apartment community parking areas
- School and church parking lots
- Retail and office parking areas
- Industrial drive lanes and employee parking lots
- Municipal and private paved surfaces
- Newer pavement that is ready for preventive maintenance
Sealcoating may not be the correct solution when pavement has widespread alligator cracking, deep potholes, significant settlement, unstable edges, or base failure. These conditions often require asphalt patching, resurfacing, or reconstruction.
Anthony’s Asphalt inspects the condition of the pavement so property owners can avoid applying a cosmetic coating over a problem that needs structural work.
Driveway Sealcoating for Michigan Homes
Residential driveway sealcoating protects asphalt from weather exposure while improving the appearance of the property. It is especially useful when the driveway is still stable but has begun to fade or show minor surface wear.
Before sealing a driveway, the surface should be checked for:
- Open cracks
- Oil or automotive fluid stains
- Loose material
- Edge deterioration
- Low areas that hold water
- Potholes or failed patches
- Extensive interconnected cracking
Open cracks may need professional crack sealing before sealcoat is applied. Repairing the right defects first helps prevent moisture from continuing to enter the pavement.
Homeowners should also plan for temporary driveway closure while the coating cures. Vehicles, lawn equipment, trailers, and other heavy items must remain off the surface for the period recommended by the contractor.
Commercial Parking Lot Sealcoating
Commercial sealcoating helps property managers and business owners maintain parking areas before widespread deterioration develops. It can also make an aging lot look cleaner and more consistent without prematurely resurfacing pavement that remains structurally sound.
Anthony’s Asphalt provides parking lot sealcoating for:
- Office and retail properties
- Apartment and condominium communities
- Property management portfolios
- HOAs
- Schools and universities
- Churches
- Warehouses and industrial facilities
- Municipal properties
- Private roads and shared parking areas
Commercial projects require more than applying a coating. Traffic flow, business hours, tenant access, pedestrian routes, loading areas, and curing time must be considered before work begins.
For active properties, the project may be completed in planned sections when site conditions and scope allow. This can help preserve access to parts of the property during maintenance.
Sealcoating can also be coordinated with parking lot repair and parking lot striping to create a more complete maintenance plan.
How Michigan Weather Affects Asphalt Pavement
Michigan pavement is exposed to repeated temperature changes, snow, ice, rain, sunlight, and freeze-thaw cycles. These conditions place added stress on asphalt surfaces.
When water enters an untreated crack, it can travel below the surface. During cold weather, that moisture freezes and expands. Repeated freezing and thawing can widen cracks, weaken pavement edges, and contribute to potholes or base deterioration.
Summer weather creates a different problem. Heat and UV exposure accelerate oxidation, causing asphalt to dry and lose flexibility. A brittle surface is less able to accommodate traffic and seasonal movement.
Sealcoating helps slow surface-level weather damage, but it does not replace proper drainage or crack repair. The most effective maintenance plan combines:
- Timely crack treatment
- Pothole and failed-area repair
- Proper surface drainage
- Periodic sealcoating
- Clear parking lot striping
- Resurfacing when surface maintenance is no longer sufficient
Our Asphalt Sealcoating Process
Professional preparation is critical to the performance and appearance of the finished coating.
1. Pavement Evaluation
We inspect the surface to determine whether sealcoating is appropriate. The evaluation considers pavement age, cracking, potholes, drainage, previous repairs, traffic levels, and surface deterioration.
2. Surface Cleaning and Preparation
Dirt, vegetation, loose aggregate, and other debris must be removed so the material can bond properly. Oil spots and contaminated areas may require additional treatment.
3. Crack and Pavement Repairs
Sealcoat should not be used to hide structural damage. Eligible cracks and damaged areas are identified so the proper repair can be completed before coating.
4. Protection of Adjacent Areas
Concrete, curbs, buildings, landscaping, garage aprons, and other adjoining features are protected during application. Clean edges contribute to a more professional finished appearance.
5. Sealcoat Application
The coating is applied evenly across the prepared pavement using methods suited to the surface and project size. Commercial areas may require scheduling in phases to manage access.
6. Curing and Reopening
The sealed pavement must remain free from vehicles and traffic while it cures. Actual reopening time depends on the product, temperature, humidity, shade, and site conditions.
7. Parking Lot Striping
If striping is included, markings are applied after the sealcoat has cured sufficiently. This may include parking stalls, directional markings, fire lanes, loading zones, and accessible parking areas.
Asphalt Sealcoating vs. Asphalt Resurfacing
Sealcoating and resurfacing solve different pavement problems. Choosing the wrong service can leave the underlying issue unresolved.
Sealcoating is appropriate when the pavement still has structural integrity. Asphalt resurfacing may be recommended when the surface has deteriorated beyond what routine coating and isolated repairs can reasonably address.
If the base has failed, complete asphalt paving or reconstruction may be necessary.
Factors That Affect an Asphalt Sealcoating Estimate
Every driveway and parking lot has different site conditions. Factors that can influence the scope and estimate include:
- Total pavement area
- Current pavement condition
- Number and severity of cracks
- Potholes or failed areas requiring repair
- Amount of cleaning and preparation
- Oil or chemical contamination
- Pavement layout and accessibility
- Number of coats specified
- Traffic levels and property use
- Required phasing for commercial properties
- Parking lot striping requirements
- Weather and curing conditions
The lowest estimate does not always provide the best long-term result. Inadequate cleaning, poor preparation, overly diluted material, or coating over failed pavement can shorten the useful life of the work.
A professional evaluation provides a clearer understanding of what should be repaired, what can be maintained, and what work can be planned for later.
How Often Should Asphalt Be Sealcoated?
Many asphalt surfaces are evaluated for sealcoating every two to three years, but there is no universal schedule. Traffic, pavement age, sun exposure, drainage, previous applications, and surface condition all affect timing.
A lightly used residential driveway may have different maintenance needs from a busy commercial parking lot. Applying sealcoat too frequently can cause unnecessary buildup, while waiting until extensive cracking develops can reduce the value of preventive maintenance.
The better approach is to inspect the pavement periodically and schedule service based on its actual condition.
Newly installed asphalt should also be given appropriate time to cure before its first sealcoat application. The correct timing depends on the pavement and site conditions, so owners should follow the paving contractor’s recommendation.

Frequently Asked Questions About Asphalt Sealcoating
How long does asphalt sealcoating last in Michigan?
Many properties are evaluated for another application after approximately two to three years. Actual performance depends on traffic, weather exposure, surface preparation, drainage, pavement condition, and the quality of the application.
When should I sealcoat a new asphalt driveway?
New asphalt needs time to cure before it is sealed. Sealing it too early may interfere with that process. Ask the paving contractor to evaluate the pavement and recommend timing based on the installation and site conditions.
Does sealcoating fill asphalt cracks?
Sealcoating may cover very small surface voids, but it is not a substitute for crack sealing. Open cracks should be treated with the appropriate repair material before the coating is applied.
Can sealcoating fix potholes or alligator cracking?
No. Potholes, interconnected alligator cracking, settlement, and base failure require repair. Applying sealcoat over these conditions may change the appearance temporarily, but it will not correct the underlying problem.
Is asphalt sealcoating worth it for an older driveway?
It can be worthwhile when the older pavement remains structurally stable. If the driveway has widespread cracking, drainage problems, potholes, or base failure, repair, resurfacing, or replacement may provide better value.
How long must vehicles stay off newly sealed asphalt?
The required curing period varies with the material and weather. Temperature, humidity, sunlight, shade, and site conditions can all affect reopening time. Follow the instructions provided for your project rather than relying on a universal timeframe.
Can a commercial parking lot remain open during sealcoating?
Depending on the layout and project scope, work may be divided into sections to preserve access. The contractor must account for vehicle routes, entrances, tenants, customers, deliveries, and curing time when planning the project.
Should cracks be repaired before a parking lot is sealcoated?
Yes. Open cracks allow water to enter the pavement and should be evaluated before sealcoating. Potholes and failed areas may also need repair to create a stable surface.
What time of year is best for asphalt sealcoating in Michigan?
Sealcoating requires suitable temperatures and dry conditions for application and curing. The contractor should schedule the work during an appropriate weather window rather than applying it when rain or low temperatures could affect the result.
What affects the cost of asphalt sealcoating?
The estimate depends on pavement size, condition, preparation, crack treatment, repairs, accessibility, number of coats, commercial phasing, and striping needs. A site evaluation is needed for an accurate estimate.
