You stand in front of a 500‑square‑meter wall. Three workers. Two days. Maybe three. The traditional way: mix mortar by hand, throw it on the wall with a trowel, scrape it flat, and pray it stays even. Slow. Exhausting. Expensive.
Meanwhile, a crew down the street with the right gear finishes the same wall by lunch—with a smoother surface and no aching shoulders. Their secret? They switched to cement render spray equipment.
Here‘s how it works and why it might be the smartest investment your construction business makes this year.
What Exactly Is A Cement Mortar Spray Machine?
A cement mortar spray machine unit is a machine that sprays mortar onto walls and ceilings instead of applying it by hand. You simply pour the mortar into the hopper, set your spray parameters, and the machine does the rest: it feeds the material through a screw pump, compresses it to high pressure, and atomizes it through a spray gun evenly across the surface.
One machine operated by 1-2 people can spray 150 square meters per hour (at 2cm thickness). Compare that to a manual crew struggling to finish 30-40 square meters in the same time. That‘s 3x to 5x faster—every single day.
YG‘s Cement Render Spray Equipment Lineup: Real Specs, No Fluff
YG manufactures four models of cement mortar spray machines: YG311, YG318, YG500, and YG711. All four share a maximum pressure of 3MPa and a recommended material ratio of 0.7-1:1:3 (water:cement:sand). Below are the core differences:
| Model | YG311 | YG318 | YG500 | YG711 |
| Maximum Pressure | 3MPa | 3MPa | 3MPa | 3MPa |
| Capacity | 3㎡/h | 3㎡/h | 3-4㎡/h | 4㎡/h |
| Applicable Material Ratio (Water:Cement:Sand) | 0.7-1:1:3 | 0.7-1:1:3 | 0.7-1:1:3 | 0.7-1:1:3 |
| Main Motor Power | 4kw | 7.5kw | 8hp/12hp | 7.5kw |
| Particle Size | ≤4 mm | ≤8 mm | ≤8 mm | ≤8mm |
| Conveying Distance | Horizontal: 30 m / Vertical: 20 m | Horizontal: 50 m / Vertical: 30 m | Horizontal: 50 m / Vertical: 30 m | Horizontal: 50 m / Vertical: 30 m |
| Hopper Capacity | 60L | 80L | 80L | 100L |
| Feed Pipe Diameter | 32mm | 32mm | 32mm | 32mm |
| Weight | 200kg | 320kg | 320kg | 320kg |
All models come with a hopper capacity of 60-100L and a 32mm feed pipe diameter. You can also choose between an electric motor or a diesel engine, depending on your job site’s power availability.
Why Switch To Automated Cement Render Spray Equipment?
Speed. A single YG machine completes 150 sqm/hour. That‘s a whole apartment‘s walls in one morning.
Consistency. Hand application inevitably leaves thick and thin spots, leading to hollowing or cracking down the road. Cement mortar spray machine delivers a uniform coating thickness with strong adhesion.
Material savings. Because the spray is precise and even, you use exactly what‘s needed—less waste, lower material costs.
Labor relief. One machine needs just 2-3 operators. The same output manually requires 6-8 trowel hands. In markets where skilled labor is expensive or hard to find, that‘s a game‑changer.
Where Can You Use YG‘s Cement Render Spray Equipment?
The machine isn‘t just for flat walls. YG‘s equipment handles a wide range of materials and applications:
- Indoor and outdoor wall plastering
- Cement mortar grouting and bridge grouting
- Waterproof and fireproof surface coatings
- Ceiling and wall decorative coatings (putty, latex paint, real stone paint)
- Garden spraying and relief effect coating
- Sound‑absorbing material spraying
- Tunnel, basement, and slope construction
It also works with putty powder, dry mortar, thermal insulation mortar, and various functional building materials with simple parameter adjustments—no frequent debugging needed.
Which Model Fits Your Jobs?
- YG311: Lightest (200kg). Best for small teams, residential jobs, or sites with limited access and narrow staircases. 4kW motor handles most standard plastering.
- YG318 or YG500: Balanced choice for most commercial contractors. 7.5kW motor, 320kg, 50m conveying distance, handles ≤8mm aggregate. The YG500 adds a diesel option for off‑grid sites.
- YG711: Highest capacity (4 m³/h) and largest hopper (100L). For high‑volume projects—apartment complexes, large commercial buildings, industrial facilities.
All models feature an integrated pump and compressor design for easy mobility, continuous screw‑type feeding with no pulse issues, and strong adhesion for uniform spraying.
