Stinger Asphalt Crack Cleaning Heat Lance

Why Surface Preparation Makes or Breaks Your Crack Repair

Many pavement contractors underestimate how much preparation affects the longevity of a crack repair. Pouring sealant into a dirty, damp crack is essentially wasted material — the bond will fail prematurely, leaving you back on the job site sooner than expected. Moisture and debris trapped beneath filler compromise adhesion at the molecular level, reducing the seal’s lifespan dramatically.

The Stinger Asphalt Crack Cleaning Heat Lance was built to solve this problem at the source. Before a single drop of sealant goes down, this tool ensures your crack is clean, dry, and properly etched — giving you the kind of prep work that professionals rely on for repairs that hold up season after season.

What This Heat Lance Does

Superior Sealant Bonding
Thorough crack preparation is the single most important factor in sealant adhesion. The Stinger heat lance drives out embedded debris and eliminates residual moisture, creating an ideal bonding surface that maximizes the lifespan of your crack filler application.

More Than Just Cracks
While crack prep is its primary function, this unit doubles as a pothole preparation tool. Use it to dry and clean pothole cavities before patching — the same principle of surface preparation applies, and the results speak for themselves.

Sealant Cleanup and Rework
Got old or excess sealant on the surface? The heat lance can soften and remelt overfill, allowing you to achieve a clean, flush finish without grinding or scraping.

Built Around a Honda Engine — No Additional Equipment Needed

At the heart of the Stinger heat lance is a 5.5 HP Honda engine, chosen for its reliability and output. This single unit replaces the need for separate drying or blowing equipment, streamlining your workflow and reducing your upfront equipment investment.

Every unit ships with everything you need to get started: the heat lance assembly, a 25-foot hose for flexible reach into tight pavement joints, and a 59-inch, 10 lb lance connected to a single-stage compressor. All you need to supply is a propane tank.

Electronic ignition makes startup simple and consistent, while the stainless steel burner is built to resist corrosion and perform reliably across heavy commercial use.

Hot Air Technology — No Open Flame on the Pavement

Unlike flame-based heat lances, the Stinger doesn’t expose your asphalt directly to fire. Instead, it combusts vapor propane and blends it with compressed air to produce a focused stream of high-velocity hot air. This approach eliminates the risk of scorching or charring the pavement while still delivering the heat intensity needed to thoroughly dry and etch the crack.

A built-in pressure regulator keeps output consistent and safe, while the stainless steel burner maintains performance over time. The rear swivel wheel allows a single operator to maneuver the machine with ease, reducing labor requirements on the job.
