Blacktop Driveway Sealcoating: A Comprehensive Guide for St. Louis Residents

The unforgiving St. Louis climate takes a toll on your blacktop (asphalt) driveway. Harsh sun, rain, and freeze-thaw cycles can lead to cracks, potholes, and a dull, lifeless appearance. But fear not, St. Louis homeowners! Blacktop driveway sealcoating offers a powerful defense against these elements, extending the lifespan and enhancing the curb appeal of your property.

What is Blacktop Driveway Sealcoating?

Blacktop driveway sealcoating involves applying a liquid protective coat to your asphalt driveway. This coat acts as a barrier, shielding your driveway from:

Water Infiltration: Sealcoat prevents water from seeping into the asphalt, which can cause cracks and potholes.
Sun Damage: The harsh St. Louis sun can oxidize and dry out the asphalt, leading to a brittle surface. Sealcoat helps protect against these harmful UV rays.
Oil and Gas Stains: Sealcoat creates a barrier that minimizes the impact of oil and gas spills, preventing unsightly stains.

The Blacktop Driveway Sealcoating Process

Here’s a breakdown of the typical blacktop driveway sealcoating process in St. Louis:

Surface Preparation: This is the most crucial step. The surface must be thoroughly cleaned to remove dirt, debris, and any loose asphalt particles. Professional companies may also use a power washer for an extra layer of cleaning.
Crack Filling: Any existing cracks are filled with a specialized crack sealant to prevent them from expanding due to freeze-thaw cycles common in St. Louis.
Application: The asphalt sealer is then applied using a squeegee or sprayer, ensuring a uniform and even coat.
Curing Time: Allow the sealer to cure completely according to the manufacturer’s instructions. This typically takes 24-48 hours, depending on weather conditions. During this time, it’s crucial to avoid driving or parking vehicles on the driveway.

Maintaining Your Sealed Blacktop Driveway

Once your driveway is sealed, proper maintenance is key to maximizing its lifespan:

Avoid Heavy Traffic During Curing: As mentioned earlier, give the sealer ample time to cure completely before driving or parking vehicles on the driveway.
Regular Cleaning: Sweep away leaves, dirt, and debris to prevent them from accumulating and compromising the seal.
Oil Spill Cleanup: Act quickly! Clean up any oil spills promptly to prevent them from staining the sealed surface.
Resealing Every 3-5 Years: Depending on weather conditions and traffic volume, plan to reseal your driveway every 3-5 years to maintain optimal protection.
