Melt and apply crack filler with one machine!
The RY10MS mastic melter and applicator was designed to load and dispense crack filling material. It can also maintain and apply hot material directly from skid mounted or trailer mastic kettles. Those options mean optimum efficiency on the job site.
This hot mastic applicator's slanted, ultra-low-profile design allows confident loading of mastic material from either the front or right side of the kettle. Material flow is carefully controlled through a large, rectangular gate valve. The design dispenses hot asphalt mastic near the center of an easy-to-swap ultra-heavy duty 8" square steel shoe. That’s how this hot rubber mastic applicator delivers even crack filler lines.
- Handle mounted controls
- A slanted kettle promotes a convenient loading from the front of the machine
- Better flow control
- Easy application
No one wants to be close to a hot kettle of crack sealer, and the RY10MS mastic applicator means no one has to. The controls are mounted on the handle and are easily usable while walking for precise application.
The mastic applicator/melter's slanted kettle means the crack filler being applied is always the right temperature to bond. It's also safer for any operator to add more filler, especially when filling from a tank. Hot crack filler can cause significant burns, so these safety precautions need to be top-of-the-line.
Flow control is also guaranteed and simple. The flow of hot material only happens when the switch on the handle is in use, and it stops the second the handle is released. That means no overflow, period, with this mastic applicator.
Its crack filling target is at least a foot per second. In most cases, the RY10MS mastic applicator exceeds that goal barring exceedingly twisted crack patterns. With this speed, parking lots are ready for sealcoating faster.
The RY10MS is the premier crack filling mastic applicator on the market. Its design is both safe and efficient for the operator. Crack filling with this machine can be a one-person operation while other prep work is underway. That makes every job site more efficient.
What the RY10MS Does Best
The RY10MS is a field-ready mastic applicator that lets one operator load, melt, and place hot asphalt mastic with speed and control. Its slanted, ultra-low-profile kettle promotes front loading for safer handling, while handle-mounted controls keep hands clear of the hot zone. A large rectangular gate valve feeds material to an ultra-heavy-duty 8-inch square steel shoe, so filler lands centered and level across cracks, seams, joints, and pothole perimeters. For crews that value production and a clean finish, this mastic crack filler machine keeps work moving.
Key Features & Benefits
- On-the-fly valve control for precise starts and stops
- Slanted kettle aids safer loading and steady flow
- 8" shoe spreads material evenly at ground contact
- Stable tracking with solid wheels and dual front casters
- Durable steel kettle helps hold working temperature

Field Performance
Open the gate and flow starts instantly; release and it stops just as fast. By directing material near the center of the shoe, the mastic applicator helps maintain a consistent bead through curves and transitions, reducing sags and overfill. Operators can settle into a steady pace on straight runs, then adjust flow for twisted cracks, utility cuts, and pothole edges. For crews juggling multiple repair methods in a day, this mastic crack filler machine fits between saw-and-seal, infrared blends, and full hot-mix patches, letting you keep the lot moving without swapping platforms. In short, the mastic applicator bridges speed and control for repeatable results.
How to Use
- 1. Pre-check: inspect tires, hoses, and controls. Stage PPE.
- 2. Warm the kettle per material guidelines; agitate to a uniform blend.
- 3. Position the shoe, open the valve, and make a short test pass.
- 4. Keep steady pace; adjust flow for curves, voids, and temperature.
- 5. Close the valve before stopping; lift the shoe for travel.
- 6. At breaks, park on level ground and secure the mastic applicator.

- Purge and clean the shoe and gate path while warm
- Close valves, depressurize lines, cap fittings before transport
- Store cool and dry; chock wheels and set parking brake
- Inspect regulators, hoses, casters, and wheels before next use
