Hot Patch Asphalt is a ready-to-use, high-performance repair material designed to permanently fix potholes, cracks, and damaged pavement in minutes. Unlike cold mixes, it bonds instantly, resists water penetration, and withstands heavy traffic—making it ideal for driveways, parking lots, roads, and municipal repairs.weather-resistant bond. Here’s how to do it right:
Prepare the Damaged Area
Clean thoroughly: Remove loose debris, dirt, and moisture using a broom, air blower, or wire brush.
Widen edges: Cut the damaged area into a trapezoidal shape (45° angle) to create a "keyway" for better adhesion.
Dry completely: Ensure the surface is 100% dry—heat helps evaporate residual moisture, but excess water weakens bonding.
Heat the Surface
Apply heat: Use a propane torch or specialized heat lance to warm the damaged area and surrounding asphalt.
Target temperature: Heat until the existing asphalt becomes glossy and pliable (~300°F/150°C).
Avoid overheating: Burnt asphalt becomes brittle; maintain even heat distribution.
Apply Hot Patch Asphalt
Pour the mix: Fill the prepared cavity with pre-heated, polymer-enhanced hot patch asphalt. Overfill slightly (5–10%) to allow compaction.
Compact immediately: Use a hand tamper, plate compactor, or vibratory roller to eliminate air pockets. Achieve a smooth, level surface.
Cure and Finish
Initial set: Allow 30–60 minutes for the patch to cool and harden.
Seal (optional): Apply asphalt sealer after 24–48 hours for added water resistance.
Clean tools: Wipe residual asphalt from tools while warm for easy reuse.
Why Hot Patching Works Best
Stronger bonds: Heat activates polymers in the mix, creating a permanent repair.
Longevity: Lasts 5+ years with proper installation, outperforming cold patches.
Cost efficiency: Minimal material waste and labor compared to full-depth repairs.
