Preventive maintenance like asphalt seal coating protects and strengthens roadways, parking lots, and driveways. Asphalt seal coating Bloomington protects it against UV radiation, water penetration, and chemical spills. This article will explain the asphalt seal coating method and its relevance in preserving paved surfaces.


  • Surface Preparation


Surface preparation is necessary before seal coating. The asphalt surface must be cleansed of dirt, trash, and plants. Repair and mend cracks, potholes, and damage. Sweeping, pressure washing, and specific equipment may clean the surface so the sealant sticks.


  • Fixing Cracks and Potholes


Wear and freeze-thaw cycles cause asphalt cracks and potholes. Before seal coating, these faults must be addressed to prevent them from deteriorating and reducing sealant efficacy. Use specialist asphalt patching products for smooth surfaces, crack filling, and pothole repair.


  • Cleaning Chemical and Oil Stains


Oil and chemical spills on asphalt decrease the binder and seal coating adherence. So, clean and remove these stains before applying sealant. To prepare the sealant surface for oil and grease stains, use a detergent or degreaser and rinse and dry.


  • Optional priming


A priming or bonding agent may be put on asphalt before seal coating. The primer improves sealant-asphalt adhesion, making the bond stronger. Priming helps aged or porous asphalt surfaces with poor adherence.



Asphalt seal coating in Bloomington is essential for asphalt surface lifespan, safety, and aesthetics. Sealcoating protects asphalt from hazardous elements, decreases surface deterioration, and improves the look of the paved area by following correct surface preparation, crack filling, cleaning, and uniform application. Property owners and governments must prioritize regular seal coating to protect asphalt infrastructure and make roads and parking lots safer and more lasting.
