Plaster Sprayer GEKO G03171 pneumatic for cement mortars, wall application, nozzle sizes 2/4/6

GEKO G03171 pneumatic plaster sprayer is designed for efficient application of cement-based mortars to wall surfaces. The tool accepts three nozzle sizes (2, 4 and 6) to adjust spray pattern and material flow according to mortar consistency and surface requirements. Suitable for both indoor and outdoor wall rendering, this plaster sprayer is intended to accelerate the application of cement renders and repair mortars in building and renovation projects.

Advantages

The pneumatic design provides steady material delivery and reduced manual effort compared with traditional trowel application. Interchangeable nozzles let you adapt spray dispersion and flow rate for fine finishing or thicker render layers. The unit is compatible with typical cement mortars and repair mixes used in construction, enabling faster coverage and more uniform surfaces. Built for site use, the sprayer supports continuous work with straightforward nozzle replacement and cleaning.

Suitable for

• Application of cement-based wall renders and plasters
• Repair mortars and patching of exterior and interior walls
• Accelerating rendering work on renovation and new-build sites
• Surfaces requiring different spray patterns or material flow rates

Key specifications

• Power type: pneumatic (air-driven)
• Nozzle sizes: 2, 4, 6 for adjustable spray patterns
• Material compatibility: cement-based mortars and repair mixes
• Application: wall rendering for interior and exterior use
• Designed for fast coverage and uniform mortar distribution

How to use

Prepare the mortar according to the mortar manufacturer's instructions to achieve the recommended consistency for spraying. Connect the sprayer to a suitable compressed air supply and fit the chosen nozzle (2, 4 or 6) based on the desired spray pattern and material flow. Hold the gun at a consistent distance from the wall and move in overlapping passes to ensure even coverage. Clean the nozzle and material passages after each work session to prevent blockages and maintain spray performance.

Usage recommendations

Use personal protective equipment, including eye protection, gloves and a dust mask, when preparing and spraying cement mortars. Test-spray on a sample board to confirm nozzle selection and air pressure settings before working on critical surfaces. For best results, adjust mortar consistency and air pressure to match the selected nozzle size and the required layer thickness.
