A Cement Mortar Spray Machine is a construction device that pumps and sprays mortar onto walls and ceilings. It replaces manual plastering work and speeds up the process significantly. These machines typically deliver 3-6 m³ of material per hour and can reach heights of up to 30 meters vertically. If you need to finish walls faster with less labor, contact YG for more product details.

How Does a Cement Mortar Spray Machine Work?
The working principle is straightforward. The machine uses a pump to push mixed mortar through a hose. At the nozzle, compressed air from an integrated compressor atomizes the material and projects it onto the wall surface.
Key components include:
- A hopper that holds the prepared mortar mix
- A pump (rotor-stator or piston type) that creates pressure
- An air compressor that provides atomization power
- A spray gun and nozzle that direct the material flow
- Control valves to adjust pressure and output rate
The machine maintains steady flow without pulsation. This ensures an even coating layer every time.
5 Benefits of Using a Mortar Sprayer Machine
A mortar sprayer machine changes how you approach wall plastering projects. Manual plastering requires skilled workers and takes days. This equipment cuts the time by over 70%.
Main advantages include:
- Labor savings: One machine replaces 3-8 workers
- Faster completion: Spray up to 150 m² per hour
- Consistent quality: Uniform layer thickness every time
- Less waste: Material loss under 5%
- Lower fatigue: Workers handle the gun, not heavy trowels
For large residential or commercial buildings, these benefits translate to real cost savings and predictable schedules.
6 Applications for Cement Render Spray Equipment
Cement render spray equipment handles many job site needs. It works for both interior and exterior surfaces.
Common applications include:
- Interior wall plastering with gypsum or lime
- Exterior facade rendering with cement mortar
- Tunnel lining and shotcrete work
- Bridge and road construction projects
- Water conservancy dam surface finishing
- Insulation material spraying for exterior walls
The machine adapts to different material types. It works with cement mortar, gypsum, lime, and ready-mix plaster.

Global Case Studies: YG Cement Mortar Spray Machines in Action
YG Machinery has exported cement mortar spray machines to construction projects worldwide. These real-world examples show how contractors solve labor shortages, improve quality, and meet tight deadlines with our equipment.
Case Study 1: UAE – Large Shopping Mall Project in Dubai
In April 2025, a leading construction company in Sharjah purchased a bulk order of cement mortar spray machines from YG Machinery. The client was a general contractor working on a large shopping mall in Dubai.
The Challenge:
The contractor faced two major problems:
- Severe labor shortages for skilled plastering work
- Tight project deadlines that manual methods could not meet
Before switching to machines, the team could only cover about 200m² per day manually. They also received quality complaints about uneven surfaces, which led to costly rework.
The Solution:
YG provided both electric and diesel models to suit different site conditions. Each machine needed only two operators—one to load material and one to handle the spray gun.
The Results:
After three weeks of use, the contractor reported:
- Daily coverage jumped from 200m² to 500m² per team
- Labor costs dropped significantly (one machine replaced 3–5 workers)
- Wall surfaces were smooth and even
- Material waste stayed under 5%
- The project finished ahead of schedule
The client said the machine “completely changed” their workflow and delivered excellent ROI despite initial concerns about the investment.
Conveying distance: Up to 50m horizontally, 30m vertically. Output: Up to 4m³ per hour.
Case Study 2: New Zealand – Residential and Commercial Construction
YG Machinery exported a batch of mortar spraying machines to New Zealand for residential and commercial building projects. Local contractors in Auckland needed a solution for faster wall finishing.
The Challenge:
New Zealand’s wet coastal climate required equipment with enhanced moisture resistance. Contractors also struggled with labor costs and inconsistent plaster quality.
The Solution:
YG engineers customized the machines for local conditions—enhancing moisture resistance for the wet environment. The machines handled various materials including cement mortar, gypsum mortar, and refractory mortar.
The Results:
Construction speed increased more than three times after adopting the spray machines. One machine could replace 3–5 skilled workers, significantly lowering labor costs. The uniform spraying ensured consistent wall thickness across all projects.
Vertical conveying: 30 meters for high-rise residential buildings.
Case Study 3: United Kingdom – 25-Home Renovation Project
In 2024, Mr. James, a building contractor from Manchester, UK, purchased a cement plaster spray machine from YG for his home renovation projects.
The Challenge:
Rising UK labor costs and tight schedules were hurting his business. Manual plastering was slow and uneven. He had previously tried another brand but it often clogged and needed frequent cleaning.
The Solution:
YG recommended a dual-motor model with a 3.0kW motor and adjustable flow system. The machine could handle cement, gypsum, and lime-based materials—perfect for his mixed projects.
The Results:
After two months of use, James reported:
- Work efficiency improved by 60%
- Labor costs dropped by 45%
- Material waste reduced by 30%
Two workers could now finish one house’s interior walls in a single day—a job that previously took three workers two full days. When James needed replacement parts, YG shipped them within 48 hours.
