Traditional manual wall plastering suffers from low construction efficiency, high material waste, and unstable surface flatness. Conventional single-function spraying equipment cannot adapt to variable site conditions, different coating materials, and high-rise construction demands, resulting in poor construction flexibility and high labor costs. This professional wall plaster spray machine adopts a gradient multi-model design with diversified power configurations, solving the pain points of single performance and narrow application range of traditional spraying equipment. It provides high-efficiency, low-loss wall spraying solutions for residential renovation, commercial construction, and outdoor mains-powered projects.

The gradient model matrix covers lightweight indoor narrow-space operation, conventional general engineering, and large-area commercial construction. Each model has clear and calibrated conveying parameters, allowing buyers to select targeted equipment according to actual floor height, site space, and construction volume.
Working Principle Of Mortar Spraying Machine
This practical machine adopts a screw pump non-pulse conveying principle to realize stable and continuous material spraying. The equipment delivers mixed mortar and coating materials through the rotor and stator pumping system, removing internal air bubbles during conveying to ensure uniform spraying thickness.
Equipped with adjustable flow control components, the wall plaster spray machine adapts to different viscosity materials by simply replacing nozzles. The movable foot wheel design facilitates flexible transfer inside construction sites. The standardized wearing parts structure enables quick disassembly and replacement, effectively reducing equipment maintenance time and construction downtime.


Core Product Features & Performance Advantages Of Mortar Pump Sprayer
- Full gradient model coverage: The 200kg YG-311 lightweight model fits narrow indoor spaces and low-rise projects. YG-318 is designed for general engineering scenarios, YG-500 supports dual electric and diesel power for field sites without municipal electricity, and the YG-711 large-capacity model meets high-output commercial construction demands.
- Humanized gun-end operation structure: The spray gun is equipped with a remote start-stop switch to avoid repeated round trips to the main unit. The 360° rotatable hose joint of the wall plaster spray machine prevents torsion and damage during corner and ceiling construction, greatly improving construction fluency.
- Multi-material compatible pumping system: It stably conveys cement mortar, dry-mix plaster, putty, real stone paint, thermal insulation, fireproof and waterproof coatings. Only nozzle replacement is required for material switching without overall machine disassembly.
- Significant construction cost reduction: It reduces mortar material waste from 10-15% of manual plastering to within 5%. A 3-person construction team can complete large-area spraying efficiently, drastically cutting long-term labor investment.
- Flexible power and mobility configuration: Dual power options adapt to urban electrified sites and remote field sites. Standard mobile casters ensure convenient on-site transfer, and standardized wearing parts simplify daily maintenance.
Main Industry Application Scenarios Of Wall Plaster Spray Machine
This multi-functional spraying equipment adapts to diversified building construction scenarios:
- Residential renovation projects: Indoor and outdoor wall plastering and putty spraying for apartments and villas
- Commercial building construction: Large-area wall thermal insulation and fireproof coating operation
- Field engineering projects: Diesel-powered model for outdoor construction without municipal power supply
- Decoration engineering: Real stone paint and waterproof coating construction for building exterior walls
Product Purchase & Selection Guidance Of Mortar Spraying Machine
Buyers can select suitable models based on project conditions and construction requirements to avoid configuration mismatch:
- Choose YG-311 lightweight model for low-rise indoor renovation and narrow-space construction projects.
- Select YG-318 or YG-711 models for high-rise buildings and large-area commercial spraying tasks.
- Adopt the YG-500 diesel-powered optional model for remote field sites without a stable municipal electricity supply.
- Strictly control material particle size within the model’s standard range to prevent pump blockage and component damage.
- Reserve manual finishing procedures after mechanical spraying to ensure wall surface flatness standards.
