Professional Sealcoating That Protects Twin Cities Pavement From Minnesota’s Harshest Conditions
In Minneapolis and throughout the Twin Cities Metro Area, Czars of Tar, Inc. provides professional sealcoating for commercial parking lots and residential driveways that face one of the most demanding pavement climates in the country. Nearly four decades of sealcoating experience across Minnesota’s freeze-thaw environment has taught us exactly what preparation, application, and sequencing look like when the goal is protection that holds up — not just a fresh appearance that fades before the next winter arrives.
Sealcoating is the single most cost-effective maintenance investment available to pavement owners. Applied correctly, on properly prepared surfaces, at the right intervals, it extends asphalt life by years and protects the significantly larger investment that replacement would require. Applied incorrectly — over unfilled cracks, dirty surfaces, or too early on new pavement — it delivers almost none of those benefits. Czars of Tar does this right. Based in Ham Lake, MN, serving the metro since 1991.
Benefits of Professional Sealcoating
- UV Oxidation Protection — Asphalt binder breaks down progressively under ultraviolet exposure, causing the surface to become brittle, gray, and prone to cracking. Sealcoating replenishes surface protection and dramatically slows this oxidation process, keeping asphalt flexible and intact through more seasons of UV exposure.
- Water and Freeze-Thaw Resistance — A properly applied sealcoat creates a water-resistant surface that reduces the rate at which moisture infiltrates cracks and surface voids. In Minnesota’s climate, reducing water infiltration directly reduces freeze-thaw damage — the primary cause of pothole formation and pavement failure.
- Fuel and Chemical Resistance — Untreated asphalt is susceptible to softening and damage from gasoline, motor oil, and de-icing chemicals. Sealcoating provides a resistant barrier against these materials, particularly important for high-traffic commercial lots where fuel and oil spills are common.
- Restored Appearance — Fresh sealcoating transforms a faded, oxidized pavement surface back to a uniform, deep black finish. Combined with restriping, a freshly sealed lot looks professionally maintained and significantly improves the visual impression of any commercial property.
- Extended Pavement Life at Low Cost — The cost of a sealcoating application is a fraction of the cost of asphalt resurfacing or replacement. Every properly timed sealcoating cycle adds years to the life of your pavement — making it among the highest-return maintenance investments available to property owners.
Our Sealcoating Process
- Pavement Assessment and Written Estimate — We evaluate your pavement’s current condition — crack extent, surface hardness, existing sealcoat condition — and confirm it’s a suitable candidate for sealcoating. Your written estimate covers the full project scope with no hidden fees. If crack filling or repairs are needed first, we scope those honestly as a prerequisite.
- Crack Filling First — Always — Sealcoating is never applied over open cracks. Every crack that needs filling or sealing is addressed first and allowed to fully cure before any sealcoat is applied. This is the step most commonly skipped by lower-quality operators — and the step that most directly determines whether the sealcoating investment delivers lasting value.
- Surface Cleaning and Preparation — The pavement surface is blown clean of all loose debris, dirt, sand, and vegetation. Oil spots receive special treatment with a primer to ensure the sealcoat bonds to the surface rather than to the oil contamination beneath it.
- Edge Masking and Protection — Curbs, sidewalks, building foundations, and any surfaces that should not receive sealcoat are masked or protected before application begins.
- Sealcoat Application — Professional-grade coal tar or asphalt emulsion sealer is applied by squeegee or spray depending on surface conditions and project specifications. Application rate and coverage are controlled to ensure a uniform, complete coat across the entire surface.
- Cure Time Management — Sealcoat requires adequate cure time before the surface can handle traffic — typically 24–48 hours depending on temperature and humidity. We apply sealcoating only in appropriate weather conditions and provide a return-to-service time specific to your project and the day’s conditions.
- Restriping Coordination — All existing pavement markings are covered by the sealcoating application. Restriping is required after every sealcoating project and is coordinated as the final phase of the complete maintenance scope.

Sealcoating FAQs
When should I first sealcoat new asphalt?
New asphalt should not be sealcoated immediately after installation. The asphalt needs time to cure fully and for volatile compounds to gas off. The recommended waiting period is 90–180 days for new pavement, depending on conditions. Sealcoating too early traps volatiles in the mix and can cause premature failure of the sealcoat layer. We’ll advise on the right timing for your new pavement during the post-installation follow-up.
How often should asphalt be sealcoated in Minnesota?
The standard recommendation for commercial pavement is every 3–5 years, depending on traffic load, UV exposure, and the condition of the existing sealcoat. High-traffic commercial lots may benefit from a shorter cycle; lower-traffic surfaces can often go the full five years between applications. We assess your specific surface during each maintenance visit and recommend the right interval based on actual conditions.
What weather conditions are required for sealcoating?
Sealcoating should be applied when pavement and air temperatures are above 50°F and rising, with no rain forecast for 24–48 hours after application. In the Twin Cities Metro, the effective sealcoating season typically runs from late April through October, depending on the specific weather window. We monitor conditions and schedule projects accordingly.
Can sealcoating fix cracks or surface damage?
No. Sealcoating is a protective coating, not a repair material. It should be applied to a sound surface after all cracks have been filled and all structural failures have been repaired. Applying sealcoat over open cracks or damaged areas doesn’t fix them — it hides them temporarily until they break through the sealcoat. All repairs and crack filling must be completed and cured before sealcoating begins.
Does sealcoating require restriping afterward?
Yes, always. Sealcoating covers all existing pavement markings. Restriping is a required follow-on step after every sealcoating application. This is also an excellent opportunity to update layouts, correct faded or worn markings, and ensure full ADA compliance in designated accessible areas. Czars of Tar provides professional striping as part of the complete sealcoating package.
