Hot-air lances have become an essential preparation tool for successful crack- and joint-sealing projects. Lab hot-air lances clean, dry and prepare pavement cracks and joints with high-velocity hot air. This ensures a dry work area for crack-filling crews to start on time, regardless of a recent rain. Because of the high-temperature hot air, crack-sealing work can be continued all year long by assuring clean, dry cracks prior to hot-pour application. The hot air completely prepares the area without disturbing the surrounding surface. High-velocity hot-air drying significantly enhances the durable bonding of any sealant. All models are constructed of stainless steel and are available with 40-, 50- or 60-ft hose kit assemblies.
