A cement mortar spray machine is a professional construction machine for automatic mortar spraying. It is usually used for wall plastering, ceiling spraying, and building renovation. It has the features of high efficiency, even coating, and labor saving. Compared with manual plastering, it cuts crew size from nine people to just three and finishes walls in half the time.

How does the Mortar Spray Work?
The cement mortar spray machine uses a rotor-stator pump. The steel rotor turns inside a rubber stator, forming a sealed cavity that moves mortar forward without pulses. Material goes into the hopper (60-80L), gets pulled into the pump, and is pushed through the 32mm hose to the spray gun. At the gun, compressed air from the onboard compressor mixes with the mortar, blowing it onto the wall. The operator can adjust both material flow and air pressure. Cleaning is simple – just run water through the system after each job.
Why Contractors Love This Mortar Sprayer Machine?
Adjustable output
Dial in the exact flow rate for thin or thick materials. For runny grout, turn it down; for sticky insulation mortar, turn it up – no clogging. You can switch between different materials in minutes without taking the machine apart.
Remote control
Start and stop spraying directly from the gun – no walking back to the panel. One operator can manage the entire wall alone without a helper at the machine. That means faster work and less tired arms at the end of the day.
Swivel gun connection
Reach corners, ceilings, and tight spots without twisting the hose. The fitting rotates 360 degrees, so the hose lies flat and lasts longer. You will not have to stop and untangle the line every few minutes.
Compact and portable
The YG-311 weighs only 200kg. One person can move it with a small dolly, and it fits through a standard doorway or onto a freight elevator. It also packs into less than one cubic meter, keeping shipping costs low.
Low maintenance
A stator/rotor set costs 300 CNY and lasts about 3,000 m² of spraying. Replacing both takes about ten minutes with basic hand tools – no mechanic needed. That is less downtime than waiting for a specialist to show up.
Material savings
Precise cement mortar spray machine reduces rebound waste by up to 30% compared to hand throwing. On a 500 m² job, that easily saves you a full pallet of cement. Lower material cost means the machine pays for itself faster.
Where Can You Put a Mortar Spraying Machine to Work?
- Spray interior and exterior walls, ceilings, and roof undersides, including high and overhead surfaces. No more lifting heavy material above your head or climbing up and down scaffolds. The machine does the hard work, so you can focus on guiding the gun for a smooth finish.
- Pump cement mortar for bridge grouting, tunnel lining, and structural repairs. It reaches deep into cracks and fills voids evenly, which is hard to do by hand. This precision also reduces the risk of weak spots or air pockets in critical structures.
- Apply waterproof membranes, fireproof coatings, and acoustic layers on walls and floors. The machine lays down a consistent thickness every time, so you meet code requirements without guesswork. Plus, you can adjust the spray pattern to match different material viscosities.
- Seal leaks and repair damp basements, dams, slopes, and underground structures. Its powerful pump pushes mortar into tight gaps and rough surfaces where trowels cannot reach. The result is a long‑lasting seal that holds up under water pressure.
- Create decorative finishes, such as textured coatings, relief patterns, garden-rock simulations, and embossed effects. Adjust the nozzle and air pressure to get everything from fine stipple to heavy orange peel. You can even switch between different textures on the same job without changing equipment.
- Spray putty, latex paint, real stone paint, and other water-based coatings. Swap materials quickly by rinsing the system with water-no special cleaning solvents needed. This saves you time between jobs and keeps maintenance simple.
- Handle lightweight materials: thermal insulation, soundproofing, and epoxy coatings. Even sticky or fibrous mixes go through smoothly without clogging the hose. The screw-pump design handles these tricky materials better than piston-type machines.
