Traditional manual plastering suffers from low efficiency, uneven quality and rising labor costs. Concrete spraying equipment is the modern solution that automates wall coating and grouting works. It sprays various materials evenly onto surfaces with consistent thickness, eliminating hand trowel marks and reducing material waste. This versatile machine works seamlessly with automatic cement plaster machines to create a complete one-stop wall construction system, covering both spraying and finishing processes in a single workflow.

Why Choose YG Concrete Spraying Equipment?
- Stepless flow adjustment: Fine-tune spraying pressure and output to achieve optimal finish for different materials and wall conditions
- Dual control system: Operate via both the control panel and the wireless remote, allowing one worker to control spraying directly at the wall
- 360° rotatable spray gun: The swivel connection between the gun and hose enables flexible operation in corners and narrow spaces
- High construction efficiency: Delivers 150㎡/h output at 2cm thickness with only 3 workers, 5-6 times faster than manual plastering
- Compact & portable: Lightweight design allows easy transportation between job sites, with low-cost spare parts and simple maintenance
- Material saving: Reduces material waste to less than 5%, compared to 15-20% waste in manual plastering
- Standard material ratio: Optimized for a 0.7:3 cement-to-sand ratio, ensuring consistent bonding strength and finish quality
Common Mistakes to Avoid When Operating Mortar Sprayers
Proper operation of concrete spraying equipment ensures optimal performance and extends service life. Avoid these common errors that cause downtime and poor finish quality:
- Incorrect material mixing: Using inconsistent water-cement ratios or aggregates larger than the machine’s maximum allowed size will cause frequent hose clogging. Always follow the recommended 0.7-1:1:3 material ratio and screen aggregates before mixing.
- Skipping daily cleaning: Failing to flush the machine and hoses after each use will allow mortar to harden inside, leading to permanent blockages and reduced pump life.
- Improper pressure adjustment: Using too high pressure causes excessive material rebound and waste, while too low pressure results in poor adhesion and uneven coating thickness.
- Ignoring safety precautions: Always wear protective goggles, gloves and dust masks during operation, and never point the spray gun at people or electrical equipment.
Concrete Spraying Equipment Sold to France
Client Background and Challenges Faced: A mid-sized local construction contractor specializing in residential and small commercial building projects faced persistent operational difficulties before adopting our equipment. They relied entirely on manual plastering teams, which struggled with three core issues: extremely high local labor costs that eroded profit margins, inconsistent finish quality that led to frequent rework requests from clients, and an inability to meet tight project deadlines due to slow work progress. On average, their manual teams could only complete 25-30㎡ of wall plastering per worker per day, and material waste often exceeded 20% due to uneven application and accidental dropping.
Resolution Strategies: After evaluating multiple options, they selected our YG318 model cement plaster spray machine for its balanced performance and reasonable cost. The equipment’s compact design allowed easy transportation between different job sites across the country, and the simple operation meant their existing workers could master it in just one day of training. Within the first month of use, they immediately noticed significant improvements: a 3-person team could consistently complete 150㎡ of high-quality plastering per day, representing a 5-fold increase in productivity. Material waste dropped to less than 5%, and rework rates fell by 80% due to the uniform, consistent finish produced by the machine.
Customer Feedback and Reviews: Six months later, the contractor purchased two additional units to expand their operations. They reported that the equipment has not only helped them complete projects on time and under budget but also allowed them to take on more contracts than before. The low maintenance requirements and readily available spare parts have minimized downtime, and the remote control feature has made working on high ceilings and hard-to-reach areas much safer and more efficient. They have since recommended our equipment to several other construction companies in their network.
