What Is Asphalt Sealcoating?

An asphalt driveway or parking lot adds nice curb appeal to any residential or commercial property. Like most property features, it requires routine maintenance to look its best and last. Weather extremes and substances asphalt is exposed to, including engine oil, fuel, and de-icers, can degrade the surface over time. That’s where Black Canvas Sealcoat, in Couer d’Alene, ID, can help. Our sealcoating process applies a protective barrier to asphalt surfaces that is impenetrable after it dries.

Benefits of Sealcoating

Your surfaces can suffer for what you don’t know about sealcoating, but we can help! Sealcoating extends the lifespan of asphalt surfaces and also saves you money on repairs or early replacements. Sealcoated asphalt is protected from: 

  • water intrusion, which can lead to cracks during freeze/thaw cycles 
  • sun exposure, which can cause fading and deterioration 
  • oil and gasoline, which can soften an asphalt surface 
  • becoming brittle, as the sealer enhances asphalt’s natural flexibility, making it less prone to cracking

How to Prep for Sealcoating

For the best results, a surface must be clean and dry for sealcoating to adhere properly. For this reason, it’s good practice to turn lawn sprinklers and irrigation off before your service time. Lawns should also remain fertilizer free for seven days leading up to your service date. 

How to Maintain Your Sealcoat 

Sealcoating aftercare ensures long-lasting benefits for your asphalt surfaces. Following these guidelines will help you keep your driveways or parking lots looking their best. Remember to: 

  • avoid driving or walking on it. Giving it time to cure lets it fully dry and harden, which usually takes about 24–48 hours. 
  • keep it clean by sweeping regularly or spraying with a hose. 
  • tend to spills or automobile leaks promptly. Cat litter, sawdust, or gravel can help absorb substances. The surface should then be swept, rinsed with a hose, and the spot should be cleaned with a dishwashing liquid or other gentle soap. 
  • choose de-icers carefully in the winter. Products like sand, calcium chloride, and safer ice melt mixtures are gentler on asphalt surfaces.
