The Cement Spray Plaster Machine is a technologically advanced construction device designed to automate the application of mortar, plaster, and other materials onto surfaces. This equipment combines mixing, pumping, and spraying functions to deliver a seamless workflow. It replaces traditional manual methods by using high-pressure systems to project materials such as cement mortar, thermal insulation coatings, waterproofing agents, and fireproofing compounds onto walls, ceilings, tunnels, and other structures.

Mortar sprayers are indispensable in modern construction due to their versatility:
Infrastructure Projects: Tunnels, bridges, dams, and subway systems.
Building Construction: Interior/exterior walls, ceilings, and decorative finishes.
Repair & Maintenance: Crack filling, waterproofing, and fireproofing.
Specialized Coatings: Thermal insulation, soundproofing, and artistic reliefs.
Mining & Underground Work: Stabilizing mine walls and tunnel linings.
The machine handles materials like epoxy mortar, latex paint, dry powder mortar, and refractory coatings, making it ideal for projects requiring speed, uniformity, and durability.
Pre-mixed materials (cement, sand, water, additives) are loaded into the hopper. A rotating screw conveyor blends them uniformly.
Pumping
The screw pump propels the mixture through reinforced hoses at high pressure (up to 3 MPa).
Spraying
Compressed air atomizes the material at the spray gun, ensuring even adhesion to surfaces. Vertical reach extends up to 40 meters, while horizontal coverage spans 60 meters.
This process eliminates manual labor, reduces material waste, and ensures consistent compaction.
By automating the plastering process, this machine cuts workforce needs by up to 70%—tasks that once required 10 workers can now be done by just 3. It also reduces material waste by 20% through precise application, saving money on both labor and supplies.
Superior Quality:
High-pressure spraying ensures the cement sticks tightly to surfaces, preventing air gaps (“hollowing”) or cracks. This creates a smooth, durable finish that lasts longer than manual methods.
Speed:
Projects get done 5–6 times faster. For example, a team can spray 600+ square meters daily compared to 100–150 m² by hand, slashing project timelines and freeing up resources.
Versatility:
It handles tricky spots like curved walls, tight corners, and high ceilings with ease, making it perfect for modern designs or complex structures like domes or arches.
Eco-Friendly:
The machine produces less dust and uses water efficiently, reducing pollution and conserving resources. This creates a cleaner worksite and supports sustainable construction practices.
Easy to Use:
With simple controls and minimal training required, even new operators can quickly master the machine, ensuring consistent results every time.
Always wear a dust mask, safety goggles, gloves, and a helmet. For high-altitude work, use a safety harness to prevent falls.
Power Safety
Check cables for damage and use leak-proof power sockets. Avoid wet areas (keep humidity below 80%) and test the machine without materials for 3-5 minutes before starting. Inspect hoses, nozzles, and pressure gauges to ensure they work properly.
Material Prep
Use finely ground materials (no larger than 5mm). Mix the mortar accurately and filter out clumps. Adding a flow enhancer can help prevent blockages.
Machine Limits
Never exceed the machine’s maximum pressure (usually marked on the device). If you hear strange noises or feel vibrations, stop immediately and check for issues. Let the machine cool down every 30 minutes during long jobs.
Workspace Safety
Keep the area well-ventilated to reduce dust. In fire-risk zones, use explosion-proof equipment. Train workers on emergency shutdown steps and keep fire extinguishers nearby.
Tips: Clean leftover mortar after each use, grease moving parts regularly, and keep records of maintenance and part replacements to extend the machine’s life and ensure safety.
Rinse the machine thoroughly with water to remove leftover material. This prevents clogs and keeps parts working smoothly.
Lubricate Weekly
Apply grease to the main pump and internal parts every week to reduce friction and wear.
Monthly Checkups
Inspect rubber seals, belts, and wires for cracks or looseness. Tighten or replace damaged parts as needed.
Keep Spare Parts Ready
Store extra nozzles, hoses, and key components to avoid delays if something breaks during work.
Yearly Professional Service
Have experts check the motor and air compressor annually to fix hidden issues and extend the machine’s life.
Extra Tips
Wipe down the machine after cleaning to prevent rust.
Store in a dry place away from extreme temperatures.
