Sealcoating in Central Ohio
Sealcoating is the single most cost-effective maintenance step you can take to protect an asphalt surface and extend its lifespan. A quality sealcoat application creates a protective barrier against water penetration, UV radiation, automotive fluids, and the oxidation that turns flexible black asphalt into brittle gray pavement. All State Paving has been providing professional sealcoating services across Central Ohio since 1979, and we have seen the dramatic difference it makes in pavement longevity.
Fresh asphalt is flexible, water-resistant, and resilient. Over time, exposure to sunlight and air causes the asphalt binder to oxidize and harden. The surface fades from black to gray, becomes brittle, and develops cracks that allow water to penetrate the base. This is not a cosmetic issue; it is the beginning of structural failure. Sealcoating reverses this process by replenishing the surface with a protective coating that blocks UV rays, seals out moisture, and restores flexibility to the top layer of the pavement.
We use commercial-grade coal tar or asphalt emulsion sealers applied at the manufacturer-specified rate with professional spray equipment. We do not dilute our materials or cut corners on application thickness. Before any sealcoat goes down, we clean the surface thoroughly, repair any cracks, and ensure proper conditions for adhesion. The result is a rich black finish that looks new and protects the surface for 2 to 3 years until the next application.
Why Choose Our Sealcoating Services?
Doubles the Life of Your Pavement
Studies consistently show that regular sealcoating can double the service life of an asphalt surface. A driveway that might last 15 years without maintenance can last 25 to 30 years with sealcoating every 2 to 3 years. The total cost of sealcoating over that period is a fraction of what premature replacement would cost.
Blocks Water, UV, and Chemical Damage
Sealcoat creates a physical barrier between the asphalt and the elements that destroy it. Water cannot penetrate to the base, UV rays cannot oxidize the binder, and oil, gasoline, and road salt cannot attack the asphalt chemistry. This three-way protection is why sealcoating is so effective.
Restores Rich Black Appearance
Oxidized asphalt looks faded, gray, and neglected. A fresh sealcoat application instantly restores the deep black appearance of new pavement. For businesses, this improved appearance enhances the property's professional image. For homeowners, it dramatically boosts curb appeal.
Fills and Seals Minor Surface Voids
The sealcoat material fills small surface voids and imperfections that would otherwise collect water. These micro-repairs prevent the early-stage water infiltration that leads to crack formation. Think of it as stopping damage before it has a chance to start.
Faster Snow and Ice Melting
A dark, sealcoated surface absorbs more solar heat than faded gray asphalt. During Central Ohio winters, this means snow and ice melt faster on sealcoated surfaces, reducing ice hazards and the amount of salt or deicer needed. This is a practical safety benefit that many property owners appreciate.
Quick Application with Minimal Disruption
Most residential sealcoating projects are completed in a few hours, and the surface is ready for traffic within 24 to 48 hours. Commercial properties can be phased so portions of the lot remain open during application. The minimal disruption makes it easy to stay on a regular maintenance schedule.
Our Sealcoating Process
Surface Cleaning and Preparation
We thoroughly clean the surface with commercial blowers and, when necessary, power washing to remove dirt, debris, oil spots, and loose material. Oil stains are treated with a primer to ensure proper sealcoat adhesion. This preparation step is critical and is where many discount sealcoaters cut corners.
Crack Repair
Any existing cracks are filled with hot-pour rubber crack sealant before the sealcoat is applied. Sealcoating over unfilled cracks simply covers the problem without fixing it. Our crack repair step ensures the surface is structurally sound before the protective coating goes on.
Professional Sealcoat Application
We apply commercial-grade sealer at the manufacturer-specified rate using calibrated spray equipment for uniform coverage. We apply two coats with adequate drying time between them, ensuring full, consistent protection. Edges, curb lines, and garage aprons are finished by hand for precision.
Curing and Barricading
We barricade the treated area and clearly mark it to prevent traffic during the curing period. Depending on temperature and humidity, curing typically takes 24 to 48 hours. We provide specific instructions on when the surface will be ready for foot traffic and vehicle use.
Sealcoating FAQ
How often should I sealcoat my asphalt?
All State Paving recommends sealcoating every 2 to 3 years for most residential and commercial asphalt surfaces in Central Ohio. This interval provides the optimal balance between protection and cost-effectiveness for our climate, which subjects pavement to harsh UV exposure in summer, frequent freeze-thaw cycles in winter, and road salt contact for 4 to 5 months each year. High-traffic commercial parking lots that see constant daily vehicle movement may benefit from sealcoating every 18 to 24 months to maintain adequate surface protection. The first sealcoat application should wait 6 to 12 months after new asphalt installation to allow the lighter oils in the binder to evaporate and the surface to fully cure and harden. Applying sealcoat too early can trap these oils and prevent proper curing. After that initial application, maintaining a regular 2 to 3 year schedule provides the best long-term protection and can double your pavement's lifespan. Contact All State Paving to schedule your sealcoat application or to set up a recurring maintenance plan for your Central Ohio property.
Can sealcoating fix cracks and damage?
Sealcoating is a preventive maintenance treatment designed to protect healthy asphalt from future damage, not a structural repair method. It creates a protective barrier against water, UV rays, and automotive fluids, but it cannot repair existing cracks, fill potholes, or address base failures beneath the surface. Applying sealcoat over unfilled cracks simply covers the problem cosmetically while water continues to penetrate and cause damage underneath. That is exactly why All State Paving always fills and seals all cracks with hot-pour rubber sealant before applying the sealcoat on any Central Ohio project. If your surface has significant damage such as widespread cracking, potholes, or settled areas, we will recommend the appropriate repairs first, whether that is crack sealing, infrared patching, or saw-cut removal and replacement, so the sealcoat can do its job effectively on a structurally sound surface. With over 40 years of experience, we provide honest assessments and never apply sealcoat over damage that needs to be repaired first. Contact us for a free pavement evaluation.
What is the difference between spray and brush application?
Professional spray application using calibrated commercial equipment delivers the most consistent coverage and the correct material thickness across the entire surface. The spray system applies sealer at a precisely controlled rate, typically 0.15 to 0.20 gallons per square yard per coat, ensuring uniform protection without thin spots or over-application. Brush and squeegee application can be effective for smaller areas, tight spaces, and detail work around curbs, garage aprons, and landscaping edges, and All State Paving uses hand tools for this precision work on every Central Ohio project we complete. We strongly advise against homeowner-grade brush-on sealcoat products available at hardware stores, as these consumer products are significantly thinner, contain fewer solids, and provide far less durable protection than the commercial-grade coal tar or asphalt emulsion sealers we apply professionally. The cost difference between a DIY application and professional service is modest, but the performance difference is dramatic. Contact All State Paving to schedule professional sealcoating for your Central Ohio driveway or parking lot and get results that actually last 2 to 3 years.
Will sealcoating make my driveway slippery?
Freshly applied sealcoat can be slightly slick when wet for the first few days until it fully cures and develops natural surface texture from normal foot and vehicle traffic. This is a common concern for Central Ohio homeowners, especially those with sloped driveways. All State Paving addresses this by using commercial sealcoat products that contain fine sand or aggregate additives blended into the sealer to provide traction immediately upon application, particularly on slopes, walkways, and high-traffic areas where slip resistance is most important. Within a few weeks of normal use, the surface develops a textured, non-slip finish comparable to standard unsealed asphalt as the top layer wears in under regular traffic. We have been applying professional sealcoat across Central Ohio for over 40 years and our material choices are specifically selected for safety and durability in our local conditions. If you have a particularly steep driveway, let us know during the estimate and we will use an enhanced traction additive formula. Contact us to schedule your sealcoating appointment.
