Why Sealcoat Your Parking Lot?
Sealcoating is the most cost-effective way to protect and preserve your asphalt investment. Here's why St. Louis property managers choose regular sealcoating.
Extend Pavement Life
Sealcoating doubles or triples the lifespan of your asphalt by protecting against water, UV rays, and chemical damage.
Save Money
At $0.15-0.25/sq ft, sealcoating costs a fraction of repaving ($3-5/sq ft). Regular sealing prevents expensive repairs.
Improve Appearance
Fresh sealcoat restores that rich, dark black finish that makes your property look well-maintained and professional.
Weather Protection
Missouri's freeze-thaw cycles crack unprotected asphalt. Sealcoating creates a waterproof barrier against the elements.
Easier Maintenance
Sealed surfaces resist oil stains, gas spills, and tire marks. Cleaning becomes faster and more effective.

How often should a parking lot be sealcoated?
We recommend sealcoating every 2-3 years in Missouri's climate. New asphalt should be sealed after 6-12 months. High-traffic areas or lots with heavy vehicle loads may need more frequent applications to maintain protection.
How long does sealcoating take to dry?
Sealcoating typically dries to foot traffic in 4-8 hours and vehicle traffic in 24-48 hours, depending on temperature and humidity. We recommend scheduling sealcoating when temperatures are above 50°F with no rain forecast for 24 hours.
What are the benefits of sealcoating?
Sealcoating protects asphalt from UV rays, water damage, oil spills, and oxidation. It extends pavement life by 2-3x, improves appearance with a rich black finish, and costs a fraction of repaving. Regular sealing can save thousands in repair costs.
Can you sealcoat and stripe at the same time?
Yes! We offer sealcoat-and-stripe bundles that save you money and minimize disruption. We apply sealcoat first, allow proper cure time (typically 24-48 hours), then stripe. This gives you a like-new parking lot in one project.
Do you repair cracks before sealcoating?
Yes, crack filling is essential before sealcoating for best results. We offer crack filling services to seal cracks up to 1 inch wide. Filling cracks prevents water infiltration and extends the life of both the sealcoat and underlying asphalt.
