Cement plaster spray machine is a construction piece of equipment used to spray cement mortar and other water-soluble materials evenly onto walls, floors, ceilings, and other construction surfaces. It replaces traditional manual plastering work by using pressure-feeding technology to transport mortar directly to the spraying surface.
Compared with manual application, the cement plaster spray machine improves construction efficiency, creates a more uniform coating thickness, and helps reduce problems such as uneven surfaces and hollow areas.
The equipment is widely used in building finishing, wall plastering, bridge grouting, waterproof coating, fireproof spraying, tunnel construction, and other projects requiring continuous mortar application.

Cement Mortar Sprayer Core Features
1. Continuous Mortar Feeding System
The machine uses a screw feeding system to continuously transport mortar without pulse interruption. This design helps maintain stable material flow and improves spraying consistency.
The integrated pump and compressor structure makes the machine compact and easier to move on construction sites.
2. Adjustable Pressure and Flow Control
The cement plaster spray machine is equipped with a pressure adjustment system that allows operators to control pressure and material flow according to different spraying requirements.
The maximum pressure can reach 3MPa, supporting stable mortar transportation and spraying performance.
3. Remote Control Operation
The equipment supports operation through the electric control box and remote switch.
This function improves operation convenience, especially for construction environments requiring flexible control.
4. Rotatable Spray Gun Design
The spray gun and feeding pipe connection can rotate, allowing operators to adjust spraying angles according to different working surfaces.
This improves flexibility for wall, ceiling, and complex surface applications.
Cement Mortar Spray Machine Structure and Working Principle
The cement plaster spray machine is designed around five main systems:
| System | Main Components | Function |
| Power System | Motor, air compressor | Provides power for feeding and spraying |
| Material Feeding System | Hopper, screw feeding pipe | Stores and continuously transports mortar |
| Pressure System | Pump, pressure valve | Creates stable high-pressure mortar flow |
| Control System | Electric box, remote switch | Controls machine operation |
| Spraying System | Pipe and spray gun | Atomizes and applies mortar onto surfaces |
The working process includes:
- Loading mixed mortar into the hopper.
- Starting the motor and feeding system.
- Pressurizing mortar through the pump.
- Transporting mortar through the pipe.
- Spraying mortar evenly through the spray gun.
The complete process reduces manual operation requirements and improves spraying efficiency.
