Wall Mortar Spraying Machine

It is used to spray cement-based mortars and similar rendering materials onto walls to speed up plastering, achieve uniform finishes, and reduce manual labor on construction projects.

Typical materials include cement mortar, lime mortar, gypsum-based plasters and many premixed render products. Compatibility depends on particle size and mix consistency; check the model's maximum allowable particle size before use.

Choose based on required conveying distance (horizontal and lift), maximum particle size the model accepts, and power/work-pressure needs. The product spec table lists model options and their conveying heights and material limits—contact the supplier if you need help matching a model to your project.

Nozzles of various diameters (4, 6, 8, 10, 12, 14 mm) are available. Use smaller nozzles for finer, thinner layers and finer mixes; use larger nozzles for thicker coats, heavier mixes, or when you need higher output per pass.

The machine offers high output pressure for consistent spraying. Actual work pressure and performance vary by model—refer to the product specification table for model-specific work pressure and conveying performance.

Maximum acceptable particle size varies by model. Some models handle finer mixes (e.g., up to about 3 mm) while higher-capacity models accept coarser mixes (e.g., up to about 5–6 mm). Check the model specifications for exact limits.

The machine is designed to be lightweight and easy to move (around 50 kg for the base unit), making it suitable for transport between job sites and for maneuvering on-site.

Regular maintenance includes flushing and cleaning the hopper, hoses, pump and nozzles after each use to prevent clogging, inspecting hoses and fittings for wear, replacing worn seals, and following the manufacturer's recommended service intervals.

Use properly mixed material (no large aggregates), strain mixes if needed, select the correct nozzle size, and flush the system with clean water or recommended cleaner after use. If a clog occurs, relieve pressure, remove the nozzle and clear it manually or with a soft brush.

Many common admixtures are compatible, but compatibility depends on the chemistry and solids content. Always test a small batch first and follow manufacturer guidance for both the mortar additive and the spraying machine.

Operators should wear eye protection, a dust mask or respirator, gloves and protective clothing. Ensure safe handling of power connections, relieve pressure before servicing, and follow local electrical and on-site safety rules. Keep bystanders clear of the spraying area.

Yes — custom processing and configuration options are available to adapt pressure settings, nozzle setups, hose lengths and other components to your specific project requirements. Contact the supplier to discuss custom options.

Check for blockages in the nozzle or hoses, inspect for air leaks in connections, verify adequate material supply and correct mix consistency, ensure the pump is receiving power, and examine seals and valves for wear. If problems persist, contact technical support.

Yes. Common replacement parts such as nozzles, seals, hoses and wear rings are typically available. For service or parts, contact your supplier or the manufacturer's service center for availability and lead times.

Training is strongly recommended to ensure safe and efficient operation. Many suppliers offer onboarding, operation manuals, and training sessions—ask your vendor about training options when purchasing.
