In the new residential building project in Santo Domingo, Dominican Republic, the construction team once faced an efficiency problem: “after mortar spraying, manual troweling and smoothing of each wall surface was required, and 5 workers could only complete a maximum of 300 square meters of walls in one day”. This dilemma was solved when YG’s “Mortar Sprayer Machine + Auto Wall Plastering Machine” was introduced.【WhatsApp/WeChat/Phone】+86 13837122632
Important note: This combined system is mainly designed for interior plastering. The maximum aggregate size in mortar should not exceed 12 mm. The plastering machine has a fixed height limit based on the selected model.
Project Background
The residential project had a tight construction schedule, and fully manual plastering limited overall progress. The construction team faced three core pain points:
1. Manual plastering has low output. Skilled plasterers are hard to hire, labor intensity is high, and progress is difficult to predict.
2. High overall operating costs. Expensive labor and uncontrolled mortar waste continuously reduce project profit margins.
3. Finishing quality depends heavily on individual workers. Wall hollowing, uneven flatness, and related rework were common.
The project team needed a reliable mechanized plastering solution to improve speed, control costs, and stabilize plaster quality at the same time.
Solution: Mortar Sprayer Machine and Auto Wall Plastering Machine
YG provides a coordinated mechanized plastering system. Value comes from the matched workflow of the cement plaster spray machine and automatic plastering equipment:
1. Efficient mortar spraying:
The mortar sprayer machine uses screw pumping technology for steady, pulse-free mortar delivery. It applies mortar evenly with strong bonding strength. The YG511 model reaches 50 m of horizontal delivery (60 m for the 12 HP version). Operators can place the machine in one fixed spot and cover the plastering area of an entire floor, removing workers from repetitive heavy manual work.
2.Controlled automatic smoothing:
The matching wall plastering machine quickly positions itself with its hydraulic system. Its vibrating scraper compacts, levels, and smooths fresh mortar as it moves upward automatically. The electric control system delivers consistent verticality and flatness, producing results more uniform than most manual plastering work.

Application Effects and Customer Feedback
After the combined solution was put into use, the improvement was clear. Under the original manual workflow, 5 workers could finish a maximum of 300 square meters per day. With the YG cement mortar sprayer and plastering machine set, a 2-person crew can steadily complete around 500 square meters each day.
The project manager calculated the on-site costs: labor requirements dropped by nearly 50%. Less mortar falls off during mechanical spraying, cutting material waste by roughly 15%–20%. In addition, wall hollowing and cracking defects are greatly reduced, and the share of plaster work passing inspection on the first try has improved significantly. This avoids extra spending and disputes caused by later repairs.
“This equipment combination has completely changed how we organize plastering work on site,” the site supervisor shared. “It is not just a mortar sprayer machine plus an auto wall plastering machine. It gives us a standardized plastering workflow that protects our schedule, quality, and profit. ”
This matched set of cement mortar sprayer and automatic plastering machine fits construction teams aiming to upgrade their plastering workflow:
1. Real estate and general construction firms:
Ideal for large residential communities and apartment blocks, where fast finishing helps speed up project handover.
2. Wall renovation and insulation contractors:
Teams specializing in interior and exterior renovation, thermal insulation, and decorative plastering can boost service competitiveness with this setup.
3. Small and medium construction contractors:
Compact and movable, the equipment set can be transferred easily between different job sites. It is a practical upgrade for contractors looking to raise plastering capacity.
FAQs
Q: Is the equipment package suitable for plastering high-rise residential buildings?
A: It depends on the model of the mortar sprayer machine and the plastering height limit. YG-1000 plastering machine supports walls up to 5 meters, which meets most standard residential high-rise interior plastering needs.
Q: Can we adjust the plaster thickness flexibly on site?
A: Yes. Both the mortar sprayer machine’s flow rate and the plastering machine’s working parameters can be adjusted to achieve the target plaster thickness from 2 mm to 30 mm.
Q: Does the package support 220V power supply commonly used in Dominican construction sites?
A: Yes. The automatic wall plastering machine supports 220V / 380V dual voltage options. The mortar sprayer machine can also be customized for matching voltage requirements.
Q: How long does it take for workers to learn to operate this combined set?
A: Most workers can master basic operation within half a day with our operation guide and video tutorials.
