Portable Waterproof Coating Powder Putty Spraying Machine

The Portable Waterproof Coating Powder Putty Spraying Machine (GLP-3A) is a mortar/coating sprayer designed to apply mortar, waterproof coatings, powder putty and similar cementitious or polymer-modified materials. It supports a variety of coating materials so long as particle size and mix guidelines are followed.

The machine's theoretical maximum conveying capacity is 3 m³/h. Actual hourly coverage varies with material type, mix consistency, nozzle, hose length and operator technique; check job conditions to estimate real output.

Key specs: max conveying capacity 3 m³/h, transport distance (hose) up to 50 m, maximum particle size < 8 mm, machine weight ~300 kg, power 4 kW, max working pressure 3 MPa, convey (vertical) height up to 50 m, hopper capacity 50 L, machine dimensions 1650 × 450 × 1200 mm.

The GLP-3A is designed for jobsite mobility (relatively compact and relocatable), but it weighs about 300 kg. Portability typically requires a pallet, small trolley or vehicle for transport and 2–4 people or mechanical aid for repositioning.

No specialized scaffolding or ground repair is required for operation according to the product description. Its design allows spraying at various angles, including roofs and recessed areas, which can reduce the need for extensive scaffolding on many jobs.

The GLP-3A is claimed to reduce material and water usage—improving transfer efficiency and minimizing waste—which can lower material costs by over 20% compared with less efficient manual methods. Faster application rates also reduce labor and scheduling costs.

The machine supports transportation distances up to approximately 50 meters (hose length). Performance may drop with longer hoses or higher vertical lifts; maintain recommended hose diameters and fittings to preserve pressure.

The unit is suitable for materials with particle sizes smaller than 8 mm. Coarser aggregates must be screened out or not used to avoid clogging or pump damage.

The machine requires a 4 kW power supply. Voltage and phase are not specified in the basic description—confirm the exact electrical requirements (voltage, phase, breaker size) with the manufacturer or product datasheet before connecting.

Regular cleaning after each use is recommended to prevent material hardening inside the hopper, pump and hoses. Inspect wear parts (nozzles, seals, hoses) frequently and replace as needed. Follow the manufacturer's maintenance schedule for lubrication, seal replacement and pump checks.

Yes. The machine is designed to spray at variable angles including ceilings and roofs without the need for special repositioning equipment, making it suitable for interior and exterior vertical and overhead work.

Operation is relatively low-labor intensity. Typical crews vary by job, but one trained operator plus 1–2 assistants (for material handling, nozzle guidance and monitoring) is common. Exact crew size depends on project scale and workflow.

Common recommended spares and accessories include extra nozzles, pump seals, gaskets, hoses and couplings, cleaning tools, and a basic set of replacement wear parts. Ask the supplier for a parts list specific to the GLP-3A.

The GLP-3A is described as multi-purpose and not strongly limited by regional/environmental conditions or surface shape. However, very cold, very hot or highly windy conditions may affect material behavior—always verify material compatibility and jobsite conditions before spraying.
