Sealcoating is a protective layer applied over asphalt pavement. It blocks water, UV rays, oil, and chemicals from breaking down the surface. Think of it like sunscreen for your parking lot.
Every commercial property with an asphalt parking lot needs sealcoating. Retail centers, office parks, warehouses, HOA communities, and industrial yards all benefit. Without it, your asphalt dries out, cracks, and fails years ahead of schedule.
A sealcoat application costs a fraction of what you would spend on repaving. Most property managers save thousands of dollars over the life of their lot by sealcoating every two to three years. It is one of the best returns on investment in parking lot maintenance.
Asphalt Paving Professionals has applied over 8,000 sealcoat applications across Chicagoland. We use commercial-grade coal tar and asphalt emulsion sealers that hold up to heavy traffic and harsh weather.
Benefits of Sealcoating Your Parking Lot
UV Protection
The sun dries out asphalt binder and makes it brittle. Sealcoating blocks UV rays and keeps the surface flexible. This stops the cracking that leads to expensive repairs.
Water Resistance
Water is the number one enemy of asphalt. Sealcoating creates a waterproof barrier that keeps moisture out of the base layer. This prevents potholes and base failure.
Professional Appearance
A fresh sealcoat brings back that rich, dark black finish. Your parking lot looks brand new again. First impressions matter for customers and tenants.
Extended Pavement Life
Regular sealcoating can double the life of your asphalt. A lot that might last 10 years without maintenance can go 20 years or more with proper care.
Our Sealcoating Process
Clean and Prep Surface
We blow and sweep the entire surface to remove dirt, debris, and loose material. Oil spots get treated with primer so the sealer bonds properly.
Crack Filling First
All cracks get filled with hot rubberized sealant before we apply the sealcoat. This stops water from getting under the surface after the job is done.
Apply Sealcoat
We apply two coats of commercial-grade sealer using spray systems and squeegee machines. Two coats gives you better coverage and a longer-lasting finish.
Cure Time
The sealcoat needs 24 to 48 hours to fully cure. We barricade the area and coordinate with you to keep traffic off the fresh surface until it is ready.
When to Sealcoat Your Parking Lot
Follow this simple schedule to get the most life out of your asphalt.
New Asphalt Installed
Fresh asphalt needs time to cure and release oils. Do not sealcoat new pavement right away. Wait at least 6 to 12 months before the first application.
First Sealcoat Application
After the asphalt has fully cured, apply the first sealcoat. This is the most important application. It sets the foundation for years of protection.
Regular Maintenance Sealcoating
Reapply sealcoat every 2 to 3 years after the first coat. High-traffic areas like drive lanes may need it every 2 years. Lower-traffic spots can go 3 years.
Inspect and Fill Cracks Between Coats
Check for cracks every spring after winter. Fill any new cracks right away. This keeps water out and makes your next sealcoat last even longer.

Chicago Weather Protection for Your Asphalt
Chicago is one of the toughest climates for asphalt in the country. Here is how sealcoating fights back.
UV and Heat Oxidation
Chicago summers hit asphalt with intense UV rays that dry out the binder. The surface turns gray, gets brittle, and starts to crack. Sealcoating blocks UV and keeps the binder flexible. This is the first line of defense in our two-season attack cycle.
Winter Moisture Finish
After summer UV weakens the surface, winter moisture finishes the job. Water, salt, and de-icers push into those UV-damaged spots and break the asphalt apart. Unprotected surfaces get attacked from two directions across a 110-degree temperature swing.
The Sealcoat Shield
Sealcoating fights both problems at once. It reflects UV in the summer and blocks moisture in the winter. One application protects your lot against the full range of Chicago weather, from 95-degree July heat to sub-zero January cold.
