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 have the impression that it boasts exceptionally high construction efficiency. Do you know why putty spray machines achieve such impressive productivity? 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 saves considerable time and naturally boosts productivity.

2. The construction is mechanized, with assembly-line operations and clearly defined roles, saving time. A putty‑spraying machine is used: the mixer prepares the putty by blending it, then pours the prepared mixture into the hopper in front of the machine’s feed pump. Sprayers continuously apply the material using spray guns. This clear division of labor ensures efficiency, and the assembly‑line process significantly cuts both time and physical effort. Saving time means boosting productivity.

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. As a result, the putty‑spraying machine can 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-compressed 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 there is no need for manual collection or troweling. However, if the wall is rough and uneven, the sprayed finish will remain bumpy. It is generally best suited for flat, well‑finished walls or repaired surfaces. We recommend applying it 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 lid must be opened to add putty. However, this method can be used on any wall surface and is suitable for applying high‑viscosity putties. Since it does not interfere with existing construction procedures, it is widely applicable to all types of walls. As long as it functions properly, it enables rapid application—approximately 150 square meters per hour.
