Concrete Mortar Spraying Machine Highlight
1. Efficient Operation: Powered by a hydraulic or pneumatic power system, the spraying speed can reach 10-20 square meters per hour, covering 3-5 times the area of manual plastering per day. This allows for faster construction schedules and is particularly suitable for large-scale projects.
2. Stable Quality: The mortar spray thickness can be precisely controlled (typically within ±1mm), resulting in a uniform coating with strong adhesion. This effectively reduces hollowing, cracking, and uneven thickness that can occur with manual operation, improving construction quality.
3. Versatile Adaptability: Compatible with a variety of materials, including cement mortar, insulation mortar, and waterproof mortar, the spraying pressure and flow rate can be adjusted according to construction needs, making it suitable for various applications, including interior and exterior walls, tunnels, and kitchens and bathrooms.
4. Material and Labor Savings: Mechanical conveying and spraying reduce mortar waste and achieve a 10%-15% higher material utilization rate than manual operation. It also reduces the labor intensity of workers bending over to apply plaster, reducing labor costs.

Mortar Sprayer Machines Application
1. Interior and Exterior Wall Construction: Efficiently completes interior and exterior plastering work on residential, office, and hotel walls. Whether using cement mortar, mixed mortar, or thermal insulation mortar, it can be evenly applied, adapting to varying wall materials and significantly improving wall construction efficiency and smoothness.
2. Tunnel and Bridge Engineering: Precisely spray shotcrete or reinforcement mortar for initial tunnel support and surface protection of bridge piers and box girders, enhancing structural impermeability and durability. Suitable for work in confined tunnel spaces and at high altitudes on bridges.
3. Kitchen, Bathroom, and Basement Waterproofing: For leak-prone areas like bathrooms, kitchens, and basements, waterproof mortar can be evenly sprayed, creating a continuous, airtight waterproof coating. This prevents leaks caused by uneven application and enhances waterproofing effectiveness.
4. Historic Building Restoration: When repairing the walls of historic buildings, the system can gently apply a matching repair mortar, minimizing damage to the original structure and preserving the integrity and historical character of the repaired walls.
