At the construction site at five in the morning, Wang—a plasterer—had already donned his mortar-stained work clothes. Today, he needed to complete 100 square meters of interior wall plastering; at his usual pace, this would require him to work until at least eight o'clock that evening, with only a half-hour break for a meal in between.

This is the daily routine most familiar to countless engineering professionals.

We are constantly talking about cutting costs and boosting efficiency, about project schedules and timelines, and about profit margins. Yet rarely does anyone stop to ask: Are the workers—sweating profusely on the front lines—not exhausted? Are the foremen—staying up until their eyes are bloodshot just to meet deadlines—not struggling?

Today, we won't dwell on cold, hard specs or make exaggerated claims. Instead, we simply want to take you inside a few real-world job sites to see exactly what kind of difference Deruitu’s equipment has made in the lives of construction professionals.

From "spending the day bent over" to "standing and watching the machines"

The construction site where Old Wang works introduced several Deruitu DM2025 intelligent plastering machines last month.

At first, Old Wang and his fellow workers were highly resistant. "How could a machine ever plaster as well as a human?" they asked. "Spend all that money just to buy a hunk of metal?"

But when the first wall was finished, everyone fell silent.

A job that previously required over a dozen people working all day could now be completed by just three people operating the machine. The wall's surface deviation was no more than two millimeters—even more uniform than the work of their most seasoned veteran craftsmen.

More importantly, workers no longer have to stoop over, trowel in hand, scraping away stroke by stroke. Now, one person simply pours the mortar into the hopper, while two others handle the spraying and troweling—effortlessly completing the entire process of feeding, plastering, and leveling.

This is the very purpose of the DM2025. It is not here to take jobs away from workers, but rather to liberate them from arduous physical labor. The labor costs saved translate into tangible profits, while the reduced physical strain is repaid with the smiles of the workers.

From "Dedicated Machines for Specific Tasks" to "One Machine Does It All"

At another commercial complex project, we encountered the Deruitu DP220 multi-functional spraying machine.

Project Manager Mr. Li explained to us that, in the past, wall construction work required preparing several different pieces of equipment: one machine for spraying mortar, another for spraying plaster, and yet another for spraying putty. Not only did this take up a significant amount of space, but moving the machinery back and forth was also a hassle; furthermore, the equipment was sensitive to voltage fluctuations, which often led to project delays.

Since I started using the DP220, all these problems have been resolved. It can spray everything—mortar, gypsum, putty, and textured stone paint.

"One machine does the work of many, saving a significant amount on equipment costs. Whether for interior or exterior walls, it can spray over 800 square meters in a single day—an efficiency rate more than five times that of manual labor."

Many people ask us: What is the biggest advantage of Deruitu's equipment compared to other brands?

Our answer is always: service.

For engineering professionals, equipment failure is a matter of the utmost gravity. A single day's delay in the project schedule can result in financial losses amounting to tens—or even hundreds—of thousands.

Consequently, we have established a dedicated technical service team to provide comprehensive support—ranging from equipment selection and on-site commissioning to operational training and after-sales maintenance. Whether you are located in any province or city within China, or at a construction site overseas, our engineers will promptly travel to your location whenever you require assistance.

If you are concerned about low efficiency in wall construction, high labor costs, or inconsistent quality, why not have a chat with us? A single, compact piece of equipment might just be the solution to your biggest problems.
