When it comes to putty spray machines, you might think of their exceptionally high construction efficiency. But do you know why these machines deliver such impressive productivity? Let’s take a look.

Speaking of Putty sprayer You might think it’s because the putty sprayer boasts exceptionally high construction efficiency. But do you know why? Let’s take a look.

1. Machine feeding is more convenient and faster than manual feeding. Construction employs a putty‑spraying machine. The mixed putty is placed directly beneath the machine’s loading pump. Start the machine and bleed out the air; once the air has been fully expelled, you can begin spraying. Throughout the process, there’s no need to re‑mix the putty, which significantly cuts down on putty‑spraying time and naturally boosts productivity.

2. The construction is mechanized, with assembly-line operations and clear division of labor, saving time. A putty‑spraying machine is used; the person mixing the putty prepares the blend and pours it into the hopper at the machine’s feed pump, while the sprayer continuously applies the material with a spray gun. This well-defined workflow significantly cuts both time and physical effort. Saving time translates into higher efficiency.

3. Machine application reduces labor intensity, preventing workers from becoming overly fatigued. When applying putty by hand, the scraper must be pressed firmly against the wall, which can be exhausting for those who lack experience or strength. Once they tire, productivity declines. In contrast, using a spray‑plastering machine significantly lowers physical strain and makes the process much easier. This allows the putty‑spraying machine to operate continuously without breaks, thereby boosting efficiency.

Putty sprayer How does it work? I’m sure many of you who haven’t used a putty sprayer are curious about this. Let’s take a look.

A putty sprayer is a high-pressure airless sprayer. It uses a mechanical pump to deliver putty directly at pressures up to 200 kg/cm². As the high-pressure putty is expelled through the spray gun nozzle, the significant pressure differential atomizes it into numerous fine particles that impact the wall. With continuous spraying, these atomized putty particles densely accumulate on the surface, while the spray gun moves at a steady speed. In this way, the atomized putty forms a uniform coating on the wall.

The above describes the operating process of a putty sprayer. To achieve optimal spraying results, when applying to flat surfaces, maintain as consistent a travel speed as possible. In areas with depressions, slow down slightly; in higher‑lying sections, increase the speed. This approach will yield a superior finish.

Putty sprayer It is divided into airless putty spraying and air‑assisted spraying:

1. Disadvantages of airless putty spraying: This method places relatively high demands on the wall surface. The wall must be smooth before spraying can proceed, and no manual scraping or troweling is required. However, if the wall is rough and uneven, the sprayed finish will still retain those irregularities. It is generally best suited for flat, elevated front walls or repaired surfaces. It is recommended to apply in two coats at a rate of approximately 400 square meters per hour. The putty used for spraying has a lower viscosity.

2. Disadvantages of air‑compressed spraying: After spraying, manual leveling is required, and the filler must be applied by opening the lid. However, this method can be used on any wall surface and is suitable for applying high‑viscosity fillers. Since it does not interfere with existing construction procedures, it is widely applicable to all types of walls. As long as it performs effectively, it offers rapid application—approximately 150 square meters per hour.
