Mastic One is the ideal solution for durable repairs to wide cracks and other distresses.
Engineered for reliability, safety and productivity, the Patcher II™ and Patcher 4™ mastic melters offer easy startup, quick melting and intuitive design to make your work more efficient.
Crafco Patcher mastic melters are designed to quickly heat material, keep it evenly mixed, and easily apply it for fast, simple pavement patching. Compatible with Crafco Mastic One, TechCrete and Matrix bridge joint material, Patcher mastic melters feature oil-jacketed double-boiler tanks and factory-tuned digital controls to ensure compliance with ASTM specifications for material heating.
With push-button startup, electronic ignition and intuitive controls, starting and operating a Patcher is simple – making it easy to train new recruits. An efficient Tier 4 diesel engine provides power, with a large fuel tank to last all day (based on an average 8-hour work day). The Patcher line boasts the fastest material melting rate in the industry, with a high-BTU diesel burner and an oil-jacketed double-boiler tank. The hydraulic agitation system is driven by a powerful 6:1 gear ratio to keep aggregate suspended and prevent stalling. Angled and staggered agitator blades sweep the bottom and sides of the tank to eliminate hot spots and dead zones. A diesel heated toolbox keeps your irons hot for touchups and scraping. When it’s time to pack up for the day, connect the overnight electric heaters to keep material warm for faster recovery the next day.
The Patchers have anti-splash lids and automatic agitator shutoff switches to protect your crew from hot sealant splashes while material is being loaded. The loading doors are also positioned ergonomically to reduce back strain and direct fumes upward, away from the crew, and the loading doors are located curbside for operator safety. The control box’s integrated controls include automatic safety switches to turn off the burner when heat transfer oil or material is up to temperature, and the control box is located on the curb side of the machine to keep crew out of traffic. Add the optional Work Area Camera to provide the driver with visibility behind the machine.
The trailer is built with continuous cold-formed, open-channel steel help prevent rust, with no welding on the flanges to prevent stress cracking. Fluid tanks are mounted above the top of the frame to avoid damage in transit, and the burner is mounted in an easily-accessible box for maintenance. All Crafco equipment goes through a multi-point run-up test at the factory before shipping to ensure quality control. And Crafco backs all equipment sales with an industry-leading 2-year warranty, hands-on training and outstanding customer support.

The Crafco EZ Patcher offers a safe and fast way to patch long, linear cracks and distresses like deteriorated longitudinal joints. See how this revolutionary skid steer attachment can speed up your work and help keep your crew safe.
Customize your Patcher II or Patcher 4 with a wide range of options and tools to meet your needs. Safety and work lights are available in several configurations for your Patcher II or Patcher 4 to direct traffic, make workers more visible and extend working hours. The optional material chute makes it easy to route mastic outside the wheel path, allowing for longitudinal joint repair without closing both traffic lanes. An optional heated chute utilizes the heat transfer oil from the double-boiler to keep material flowing freely in cool weather.
Hauling buckets of hot material by hand is a thing of the past with the Crafco Hot Mastic Applicator. Fed from your full-size Patcher II or Patcher 4, this 10-gallon cart allows for mastic application on meandering cracks or in tight locations like parking garages. With an ergonomic, reversible handle for versatility and operator safety, gate control and built-in applicator shoebox, the Hot Mastic Applicator allows for one-person operation. The built-in propane burner keeps material at application temperature, while a long agitator handle provides leverage to keep aggregate from settling. Add the Hot Mastic Applicator to your patching fleet for a truly versatile operation.
Crafco Drag Boxes for the Patcher II and Patcher 4 enable quick and easy application of mastic for various longitudinal repairs. Available in sizes from 4” to 48” wide, simply attach to the Patcher and drive down along distresses like cold joints and alligator cracks to ensure fast and efficient repairs.
