The operational efficiency of putty spray machines Mechanized operation and assembly-line workflows with clearly defined roles save time. By using a putty sprayer, a putty mixer handles the blending, after which the prepared putty is fed into the hopper upstream of the oil‑pump. The sprayer then applies the material continuously via its spray gun. This clear division of labor and streamlined production process significantly cut down on both time and effort—saving time translates directly into enhanced productivity.

　　The operational efficiency of putty sprayers

　　When it comes to putty spray machines, you might think of their high efficiency. But do you know why these machines deliver such impressive performance?

Putty sprayer

　　1. Machine feeding is more convenient and faster than manual feeding. By using a putty‑spraying machine, the pre‑mixed putty is placed directly beneath the machine’s feed pump; after starting the machine and venting the air, spraying can begin. Throughout the process, there’s no need to repeatedly lift and transfer the mixed putty, significantly reducing application time and naturally boosting productivity.

　　2. Mechanized operations and assembly-line workflows, with clearly defined roles, save time. A putty‑spraying machine is employed: a putty mixer prepares the compound, which is then transferred to a hopper positioned upstream of the oil‑pump‑driven sprayer. The sprayer uses a spray gun to apply the material continuously. This well‑structured division of labor streamlines production, significantly reducing both time and effort; saving time translates into enhanced efficiency.

　　3. Using a machine reduces labor intensity, preventing workers from becoming overly fatigued. When applying putty by hand, pressing the scraper against the wall can be exhausting for those who lack experience; once they tire, their efficiency declines. In contrast, employing a spray‑plastering machine significantly lowers physical strain and makes the process much more manageable, allowing the machine to operate continuously without breaks and thereby boosting productivity.

　　How does a putty sprayer work? Many people who haven’t used one before are probably curious about this—let’s take a look.

　　A putty sprayer is a high-pressure airless sprayer that uses a mechanical pump to deliver putty at pressures up to 200 kg. As the pressurized putty exits the spray gun nozzle, the significant pressure differential atomizes it into numerous fine particles, which impact the surface. With continuous spraying, these atomized particles densely accumulate on the substrate. By moving the spray gun at a steady speed, the atomized putty forms a uniform coating on the wall.

　　The above outlines the operating procedure of the putty sprayer. To achieve optimal spraying results, when applying to a smooth surface, maintain as consistent a travel speed as possible. In areas with depressions, slow down; in raised areas, speed up—this will yield a more uniform finish.

　　Putty sprayers are categorized into airless putty spraying and air-compressed spraying.

　　1. Disadvantages of airless putty spraying: This method places relatively high demands on the substrate; the surface must be properly leveled before spraying, and no manual troweling is required. However, if the substrate is rough or uneven, the sprayed finish will retain those irregularities. It is typically suitable for flat, high‑rise front walls or repair work. We recommend applying two coats at a rate of approximately 400 m² per hour, using a low‑viscosity putty mix.

　　2. Disadvantages of air‑compressed spraying: After application, manual leveling is required, and the surface must be opened to apply putty. However, this method can be used on any wall or with high‑viscosity putty without disrupting existing procedures, making it widely suitable for all types of walls. The key advantage is speed—approximately 150 square meters per hour.

　　That’s all for today’s introduction. If you’re in need of a putty spraying machine, please contact our manufacturer.
