Mortar Spraying Machine Applications
Different construction tasks call for different spraying methods. This wall plastering machine covers a wide range of work, from ordinary wall plastering to waterproof and fireproof surface treatment.
Wall and Ceiling Spraying
- Interior wall plastering
- Exterior wall plastering
- Ceiling spraying
- Wall spraying
- Coating spraying
- Decorative coating spraying
- Embossed-effect coating spraying
For large wall areas, continuous material feeding reduces interruptions during application. Ceiling work also benefits from the flexible spray gun connection.
Grouting and Waterproofing
Bridge and building projects often require more than ordinary plastering. Suitable applications include:
- Cement mortar grouting
- Bridge grouting
- Waterproof surface spraying
- Waterproof plugging
- Waterproof repair
- Fireproof spraying
Basements, tunnels, dams, slopes, houses, and factory buildings can all use this type of cement mortar sprayer for surface treatment and repair work.
Garden and Special Surface Work
The spraying method also suits garden applications and decorative surface work. Contractors can use suitable materials for textured finishes, embossed effects, sound absorption, insulation, and waterproofing.
Materials for Mortar Spraying Machine
- Putty powder
- Coatings
- Latex paint
- Natural stone paint
- Cement mortar
- Dry mortar
- Insulation mortar
- Waterproof materials
- Fireproof materials
- Heat-insulation materials
- Sound-absorbing materials
Particle size can reach up to 8 mm according to the listed specifications. For cement mortar work, the recommended water, cement, and sand ratio falls around 0.7–1:1:3.
Good material preparation also matters. A suitable mixture allows smoother feeding through the 32 mm pipe and helps maintain consistent spraying.
Mortar Spraying Machine Features
Practical operating functions make the mortar plastering machine suitable for regular construction work.
Adjustable Material Flow
Flow adjustment lets operators change the output according to the surface and required spraying effect. A suitable flow rate also helps control material application during different jobs.
Remote Spraying Control
Besides the switch on the electric control box, a remote switch provides another way to control spraying. Operators can start or stop the spraying process without returning to the main control box each time.
Rotatable Spray Gun Connection
A rotating connection joins the spray gun with the feeding pipe. Operators can change the spraying direction more freely, which helps during wall corners, ceiling work, and other restricted areas.
Compact Construction
Limited site space does not create a major problem for this portable mortar spraying machine. Its compact structure makes movement between working areas easier.
Simple Maintenance
A straightforward structure keeps routine maintenance manageable. Lower accessory costs also reduce the expense of regular replacement and repair.
Mortar Spraying Machine Advantages
Beyond basic spraying, the design focuses on continuous feeding, convenient operation, and practical construction efficiency.
Integrated Pump and Compressor
Pump and compressor components work as one compact unit. This arrangement simplifies transportation and keeps the working setup relatively compact.
Continuous Screw Feeding
A screw-type feeding system supplies material continuously without noticeable pulsation. Continuous feeding gives operators a steadier material supply during long spraying operations.
Wide Practical Use
Ordinary mortar remains one of the main applications. At the same time, the cement mortar spraying machine handles waterproof, fireproof, insulation, and sound-absorbing materials when the material meets the required specifications.
Uniform Spraying and Strong Adhesion
Correct material preparation and flow adjustment help produce an even spray. Suitable mortar also provides strong adhesion to the working surface.
Spraying and Grouting Functions
One unit supports both spraying and grouting work. Contractors can use the same machine across several stages of a construction project.
Lower Labour Demand
A three-person team can operate one unit under suitable working conditions. With a 2 cm spraying thickness, output can reach around 150 m²/h, which reduces manual plastering work and saves labour time.

FAQ
What power supply does Model 318 require?
Model 318 uses a 7.5 kW motor with a 380 V power supply. Buyers should check the available electrical supply at the project site before selecting this version.
What particle size can the feeding system handle?
The specified through particle size reaches ≤8 mm. Material preparation should stay within this range to maintain suitable feeding conditions.
How large is the hopper?
Both listed models use an 80 L hopper. This capacity suits continuous feeding during routine plastering and spraying work.
What feeding pipe size comes with the machine?
The inner diameter of the feeding pipe measures 32 mm. This specification matches the listed material and particle-size requirements.
How should customers choose between the two models?
Power availability provides a practical starting point. Projects without a suitable electrical supply may consider the diesel version, while sites with a 380 V supply can consider Model 318.
