A gypsum spraying machine is a specialized construction tool designed to apply gypsum plaster and other dry-mix mortars evenly and efficiently onto wall surfaces. It eliminates the slow, labor-intensive process of manual plastering, significantly increasing productivity and ensuring a consistent finish across large areas. Widely used in residential and commercial construction projects, it handles a range of materials including gypsum plaster, cement mortar, lime plaster, and more. Our YG-20 model automatic gypsum spray plaster machine offers reliable performance tailored to modern construction needs. With a compact footprint of 110×70×140cm and a weight of only 145kg, it is easy to move between floors or job sites. Its 5.5kW motor delivers a 30L/min flow rate, while the 20m vertical spraying reach and 80m horizontal range make it suitable for multi-story buildings. The 115L hopper volume reduces the need for frequent refills, allowing crews to work continuously.

Key Applications of Gypsum Spraying Machine
- Residential Construction: Ideal for apartment complexes and single-family homes, where it speeds up interior finishing by covering large wall areas quickly with uniform gypsum plaster.
- Commercial Buildings: Perfect for offices, hotels, and retail spaces that require consistent, high-quality finishes on walls and ceilings.
- Renovation Projects: Effective for applying new plaster layers over existing surfaces or for repairing damaged sections of walls in older buildings.
- Specialized Coatings: Works with self-leveling mortar, fireproof mortar, insulation materials, and grouting compounds, expanding its utility across different construction tasks.
- This flexibility means a single auto mortar wall plaster machine can handle multiple stages of a project, reducing the need for additional specialized equipment.
5 Gypsum Spraying Machine Advantages
Our gypsum wall plaster machine is engineered with on-site practicality in mind, delivering five core benefits that directly improve construction workflow:
- Industry-leading efficiency: The 30L/min steady flow rate allows a single operator to cover 400-500 square meters per day, which is 4-5 times faster than traditional manual plastering. This cuts project timelines dramatically and reduces overall labor requirements.
- Uniform and consistent finish: The precision spray system ensures even coating thickness across all wall surfaces, with variations controlled within ±1mm. This eliminates uneven patches and reduces post-spraying rework by up to 80%.
- Fully adjustable flow control: Operators can fine-tune the output rate from 0 to 30L/min to match different material consistencies, wall conditions and project requirements. This adaptability ensures optimal results for both rough base coats and smooth finishing coats.
- Intuitive and easy operation: The user-friendly control panel features one-button start/stop and automatic material feeding, eliminating complex manual adjustments. Even inexperienced workers can master basic operations after just a few hours of training.
- Compact and highly portable: Weighing only 145kg with a small footprint, the machine can be easily transported by two people and fits through standard doorways. It navigates narrow corridors and works efficiently on multi-story construction sites without heavy lifting equipment.
Why Are Contractors Switching to Mechanical Plastering?
Many construction professionals are moving away from manual plastering and adopting mechanical spraying methods, and the benefits are clear:
Faster project completion: Mechanical application can cover up to 4-5 times more surface area per day compared to manual work, allowing contractors to meet tight deadlines and take on more projects.
Consistent quality: Spraying ensures uniform thickness and texture across every part of the wall, eliminating the uneven finishes common with manual application.
Reduced material waste: The controlled spray pattern minimizes overspray and material loss, resulting in significant savings on plaster and mortar costs over the course of a project.
Improved working conditions: Less manual lifting and repetitive motion reduce physical strain on workers, lowering the risk of injuries associated with traditional plastering.
How to Maintain Your Gypsum Spraying Machine for Long-Term Use?
Proper maintenance is essential to keep your automatic gypsum spray plaster machine running smoothly and avoid costly downtime on job sites:
- Daily cleaning: Flush the entire system with clean water immediately after each use to remove residual mortar, preventing clogs in the pump, hoses and nozzles.
- Pre-shift inspection: Check all hoses, seals and connections for signs of wear or leaks before starting work each day. Address small issues early to prevent major breakdowns.
- Regular lubrication: Follow the recommended schedule to lubricate all moving parts, ensuring smooth operation and extending the lifespan of critical components.
- Proper storage: Keep the gypsum wall plaster machine in a dry, covered area when not in use to protect it from moisture, dust and extreme temperatures that can damage the motor and pump.
5 FAQ About YG Gypsum Spraying Machine
A: Yes, it works with all standard pre-mixed dry mortars, including gypsum plaster, cement mortar, lime plaster and polymer-modified mortars. Just ensure the maximum aggregate size does not exceed 6mm.
A: Within its rated 20m vertical and 80m horizontal range, the machine maintains consistent pressure and spray quality. For longer distances, you can slightly reduce the flow rate to compensate for minor pressure drops.
A: Absolutely. The simplified control system and automated feeding mechanism make it very beginner-friendly. Most workers can operate it independently after a half-day of basic training.
A: Incorrect mixing can cause uneven spray patterns, frequent nozzle clogs, inconsistent material flow and accelerated wear on the pump. Always follow the material manufacturer’s recommended mixing instructions.
A: With regular maintenance and proper operation, you can expect 5-10 years of reliable service. The high-quality wear-resistant components ensure long-term performance even with daily heavy use.
