Why Seal Coat?
Asphalt is a petroleum product. Over time, UV rays, rain, and vehicle fluids cause the binders in the asphalt to break down through oxidation, turning the surface gray and brittle. Seal coating replaces these essential binders, waterproofs the surface, and dramatically slows the aging process. A well-timed seal coat program can double or triple the usable life of your pavement compared to leaving it untreated — at a fraction of the cost of full replacement.
We serve commercial parking lots and residential driveways throughout Concord, Charlotte, Huntersville, Mooresville, Kannapolis, and surrounding communities. Most jobs are completed in a single day.
When Is the Right Time to Seal Coat?
Timing matters. Seal coat too soon on new asphalt and you trap volatile compounds that need to off-gas. Seal too late on aging pavement and oxidation has already set in too deeply.
- New asphalt: Wait 6–12 months before the first seal coat to allow proper curing and off-gassing.
- Existing asphalt: Reseal every 2–3 years, or when the surface begins to look gray or faded rather than black.
- After repairs: Seal coat is the ideal follow-up step after crack filling or patching — it unifies the surface appearance and seals everything in one pass.
- Before re-striping: Apply seal coat first, let it cure 24–48 hours, then re-stripe over the fresh dark surface for maximum line visibility.
Our Process
- Thorough Cleaning: We use high-powered blowers and wire brooms to remove all dirt, debris, and loose aggregate. The surface must be completely clean for proper adhesion.
- Crack and Oil Spot Treatment: We fill open cracks and prime oil and gas stains so the sealer adheres without peeling.
- Application: We apply commercial-grade coal tar or asphalt emulsion sealer — often mixed with silica sand for added traction and durability — using squeegee or spray methods depending on surface size and condition.
- Curing: The surface requires 24–48 hours to fully cure before vehicle traffic can resume. We'll give you a precise window based on the day's temperature and humidity.
Commercial Seal Coating
For parking lots, retail centers, HOA common areas, apartment complexes, and industrial facilities, we plan around your hours of operation. Large lots are typically done in sections — one half sealed while the other half remains open for traffic — with work sequenced to minimize disruption to tenants and customers.
Commercial sealing jobs often pair with parking lot re-striping to give the entire lot a freshly paved appearance at a fraction of replacement cost. Property managers across Concord and Charlotte schedule this combination every 2–3 years as part of their pavement maintenance budget.
Residential Driveway Seal Coating
For homeowners, seal coating is the most cost-effective preventive maintenance you can do for your driveway. A typical residential driveway is completed in a few hours and is ready for foot traffic by the next morning. We block the driveway with cones and clean up before leaving — the only thing you'll notice is the rich, fresh-asphalt look.
Driveways in the Concord and Charlotte area take a beating from summer UV and the freeze-thaw cycles in late winter. Resealing on a regular 2–3 year schedule keeps the surface flexible and water-resistant through both extremes.
How Long Does Seal Coating Last?
On a properly prepared surface with normal traffic, a quality seal coat lasts 2–3 years. High-traffic commercial entrances or areas with heavy turning may need attention closer to 2 years. Lightly used residential driveways can stretch to 3 years between applications. We'll tell you honestly when you call — we don't oversell reapplications.
Frequently Asked Questions
Can I seal coat myself?
Hardware store sealers are heavily diluted, require careful application, and often peel within a season. Professional-grade commercial emulsion goes on thicker, bonds better, and lasts significantly longer. For a large driveway or any commercial surface, the cost difference versus a professional application doesn't justify the DIY risk.
Do I need to repair cracks before sealing?
Yes. Sealer bridges small surface cracks but won't structurally repair open cracks wider than about ¼ inch. We handle crack filling and patching as part of our prep work so you don't need to coordinate separate contractors.
Will seal coating fix my faded lines?
Seal coating will cover faded parking lines, making the lot look uniform and fresh. New striping is applied after the sealer cures so lines are bright, visible, and ADA-compliant.
