In today's plastering projects, winning a bid at a low price guarantees a loss, while bidding high means no one will award you the contract. After all is said and done—working tirelessly day in and day out—you end up having done nothing but work for the laborers.

But have you ever stopped to wonder: why is it that on the exact same project, others turn a profit while you merely break even—or even suffer a loss? It is not because your management is poor, nor is it because you are cutting corners; rather, it is because others long ago abandoned the "human-wave tactic." By relying on mechanized plastering, they have firmly seized control—and the initiative—regarding costs, timelines, and quality.

In today's article, we’ll cut the empty talk and give you the definitive breakdown: Can plastering machines actually be used? How do you choose the right one? And—most importantly—how can you leverage one to drive down plastering costs and boost your profits?

The market for plastering machines is a mixed bag, and many people have fallen into costly traps. However, I’m here to tell you today that 90% of those who claim "machines can't match manual labor" simply haven't chosen the right machine or found the right manufacturer.

Myth #1: Machine-applied plastering won't pass supervisory inspection?

False. Current national standards require that plastering flatness deviations not exceed 4 mm. Manual plastering relies entirely on the craftsman's tactile judgment; even the most skilled craftsman will inevitably produce slight surface irregularities after a full day's work, often resulting in flatness deviations exceeding 3 mm, while the rework rate due to hollow spots typically ranges from 10% to 20%.

In contrast, Deruitu’s DM intelligent plastering machine utilizes microcomputer-controlled automatic leveling, consistently maintaining flatness errors within a stable tolerance of 2 mm. When paired with a spraying machine—executing a "spray-first, plaster-later" sequence—it can plaster over 800 square meters per day, achieving construction efficiency far superior to manual labor.

The Deruitu DP220 is a versatile machine capable of spraying mortar, gypsum, and thick-layer fireproofing materials. It is perfectly compatible with both 220V and 380V power supplies. Utilizing high-pressure atomization technology, it ensures deep penetration of the coating into wall crevices, thereby eliminating voids and preventing the need for rework.

Currently, many projects undertaken by state-owned and central enterprises explicitly mandate mechanized plastering; this is precisely because it offers stable, traceable quality and is more reliable than manual labor.

Myth #2: Plastering machines are only suitable for large construction sites and cannot be used for small-scale projects?

False. Many people assume that plastering machines are exclusively large-scale equipment—cumbersome and highly inconvenient to move around. However, modern plastering machines have long since evolved to cover every conceivable scenario: thanks to their modular design, they can be lifted by just two people, transported in a standard van, and can even easily navigate through narrow passageways as tight as 70 centimeters.

Myth #3: Machines are too expensive and take too long to pay for themselves—wouldn't it be better to just hire people?

Let me break down the actual numbers for you, and you’ll see exactly what I mean: A single skilled plasterer can cover, at most, 80 to 100 square meters per day. In contrast, a single machine—operated by a team of just four general laborers—can consistently complete over 800 square meters of work in a single day. That is equivalent to the daily output of 10 veteran plasterers, representing a direct increase in labor efficiency of 60%.

Based on an interior wall project spanning 100,000 square meters—assuming a daily work rate of 800 square meters—the job would take 125 days to complete. At a daily wage of 500 per worker, a team of 10 laborers would cost a total of 625,000 (10 × 500 × 125). In contrast, a team of just four workers utilizing machinery would incur labor costs of only 250,000. Given that a single set of machinery costs just over 100,000, this approach not only allows you to fully recoup your initial investment but also enables you to generate hundreds of thousands in additional profit.

Many friends have fallen into the same trap before. They bought the machine, but the manufacturer didn't care. When it broke down, no one repaired it. No one taught them how to use it, and the machine just sat on the construction site as scrap metal.
